EPA  Evaluation  of  the Dynamix  Device Under  Section  511  of  the Motor
Vehicle Information and Cost Savings Act

The  Motor  Vehicle  Information and  Cost  Savings  Act  requires  that  EPA
evaluate fuel  economy  retrofit  devices  and publish  a summary  of  each
evaluation in the Federal Register.

EPA  evaluations are  originated upon the  application  of any manufacturer
of a  retrofit device,  upon the request of  the Federal Trade Commission,
or upon the motion of  the EPA Administrator.  These studies are designed
to determine whether the  retrofit  device increases fuel  economy  and to
determine whether the representations made with respect to the device are
accurate.   The  results of  such studies  are  set  forth  in a  series of
reports,  of which this is one.

The  evaluation  of the Dynamix  device was  conducted  upon  receiving an
application for an  evaluation  from the inventor/marketer  of  the device.
The  device  is  claimed  to permit  an  engine  to operate efficiently  on  a
blend of  gasoline and alcohol.   The device is an auxiliary fuel system.

The following is  a summary  of  the  information on  the device as supplied
by the Applicant and  the resulting  EPA analysis and conclusions.

         (2)  Chairman of the Board - Mr.  Fred Velayo  (representing the
                   Herdis group  of Companies)
              President - Mr. Walter Brown
              Vice-President - Annabelle P. Brown
              Treasurer - Mr. Fred Ramos

              Note:  "The  above  are manufacturer/licensees of  the device
              for  the  Philippines  belonging  only  to  Vulcan  Industrial &
              Mining Corp."

3.  Description of  Product (as supplied  by Applicant);

    a.   Purpose;

         "An  add  on  device for  the  conventional  [internal]  combustion
         engine (gasoline fed) to  efficiently mix hydrous  alcohol as low
         as 160 proof  or  even lower with regular gasoline in  vapor form
         and  in  recommended proportions  of  30% alcohol  to 70%  regular
         gasoline.

         "Note;  The device  can  however operate  on a  wider range  of
         proportion  including  pure  alcohol   or pure gasoline,  at  the
         option of  the motorist.  The above add on device can efficiently
         use the above fuels on  an unmodified  engine."

    b.   Theory of  Operation;

         "While alcohol is  considered as  a leading  source of  alternative
         form  of  energy  by  reason  of   past  utilization   by  several
         countries  in  the  past,  it is  not without  problems.   Mainly the
         need to use waterfree alcohol  (anhydrous  199.5  proof)  to prevent
         phase   seperation,  which  can  cause   deteriorated   engine
         performance; cold  starting problems; comparatively higher  fuel
         consumption (than  if you were to use pure  gasoline);  the  high
         solvent action  of alcohol causes  fuel line impurities to  get
         dislodged   and clog  up  the  carburetor  jets  to  cause  engine
         stalling,    corrosion,   and  other   undesirable   factors.    The
         af©restated,  result from  the traditional method  of  blending
         alcohol with  gasoline  in  one  fuel   tank  particularly in  mixed
         fuel  proportions  higher  than  20%  alcohol  to  a  proportionate
         amount of  gasoline.

         "Other Considerations;

-------
(1)  "Cheaper Fuel

     "Furthermore,  even   on  the  assumption   that  there   is
     troublefree  operation  in  the  traditional  way  of  blending
     alcohol  to  gasoline,  now  more  popularly  referred  to  as
     "gasohol",   the   strongest   deterrent  in  its   widespread
     application  throughout  the  world  is  the  high  cost  of
     producing  anhydrous  alcohol,  in  view  of  the  additional
     infrastructure  required   to  dehydrate   the  alcohol   as
     compared  to  the   prevalent  alcohol distilleries  throughout
     the   world   producing   189   proof-alcohol.    Additional
     distillation/dehydration columns  have to  be added  to  the
     conventional   alcohol    distillery   producing   189   proof
     alcohol, not to mention  the higher cost of  operation due to
     more manpower and energy required to produce  it.  160  proof
     alcohol  is  even   cheaper  to produce  than  189  proof.    The
     efficient  utilization  of this  type  of fuel  alcohol  alone
     can result in considerable  savings.

(2)  "Vaporization Thru Heat

     "The high  latent  heat  of alcohol  requires  a higher source
     of heat.  To vaporize alcohol sufficiently, the heat source
     must be  other than  the fuel  line or  the heating  of  the
     incoming  air thru the  intake  manifold.   If  you  heat  the
     fuel line  of the  alcohol,  you will  develop vapor lock  and
     the engine will  stall.   If you heat  the  incoming air,  you
     will  dilute  the  fuel  and  air  charge   and  reduce   the
     volumetric efficiency  and  reduce  the power  output  of  the
     engine.  The heat must therefore be supplied  in a localized
     point  to  vaporize  alcohol  and  yet  not  affect  the  two
     aforementioned factors  affecting  fuel   delivery  and  the
     volumetric efficiency of the air/fuel  charge.

(3)  "Utilization of Waste Heat

     "Likewise, the  heat  supplied  should  be  inexpensive,   not
     draining  additional   energy  from   the    engine   or    the
     electrical system.   Ideally  then,  it  must  utilize   waste
     heat.

(4)  "Supplying Air and Alcohol  Fuel  in  Metered  Quantities

     "The need likewise exists to supply air and fuel  alcohol in
     metered quantities into  the  intake manifold  of the engine
     since  an  indiscriminate  supply   of   either  factor   could
     adversely affect  engine operation.   A system  must therefore
     be  incorporated  into  the  device/system  that  will supply
     fairly  adequate supply of air and  fuel alcohol  in  response
     to the  varying needs of  the  engine at different RPMs.    The
     device/system  must  therefore   attempt  to  equal  if   not
     surpass  the   conventional   carburetor  which  even  in   its
     present form is still an admittedly inefficient  supplier  of
     vaporized fuel and air  in precise quantities at  any given
     time of engine operation."

-------
c.   Construction and Operation;

     "...  the device/system operates  as  follows:

     (1)  "It utilizes  160  Proof alcohol.   (Some  road  tests  were
          conducted using  as low as 140 proof.)  This type of alcohol
          is much cheaper  than 199.5  proof  anhydrous alcohol.

     (2)  "Heated air coming from a  heat  exchanger with air supplied
          from the PCV and air cleaner passing thru [through] a small
          pipe,  combine with finely sprayed alcohol in a vaporization.
          chamber,   just  before   the intake  manifold.    Heated  air
          easily achieve  temperatures  of  120  degrees C  and higher.
          Dynamometer tests  show  that  this   heat source  does  not
          deteriorate  engine  power.   On  the  contrary,   power  is
          consistently  improved,  percentages   of  power   increases
          varying  with   engine  types.    Superior  vaporization  have
          resulted  in improved mileage,  in such tests.  Likewise,  the
          fuel/air   charge have  not  been  diluted inasmuch as  the
          increased volumetric efficiency  improved  the  power.   There
          have  never been  an  instance   of   fuel line   vapor  lock
          throughout the dynamometer  and extensive  road tests.

     (3)  "A jacketed heat  exchanger easily attached to  the exhaust
          pipe immediately  after the  exhaust  manifold  heats  up  the
          air coming from  the PCV and air cleaner before it  is sucked
          thru  the  vaporization  chamber  where  it   combines  with
          sprayed alcohol.  The  heat  from the exhaust pipe  is free.
          The system makes efficient  utilization of the waste heat of
          the exhaust pipe to supply  heat  to the  alcohol.

     (4)  "The air  coming  from the PCV has  a  PCV valve,  and likewise
          with the  air  coming  from  the air cleaner.  When there are
          no PCV valves, the system is supplied.  Most motor vehicles
          are  now  provided  with   such   PCV   valves  which  supply
          additional air  to the  intake  manifold  in  accordance  with
          vacuum pressures  and which are  already calibrated  by  the
          various    automotive/truck    manufacturers    into   their
          respective engines.   The device/system, simply  makes  use of
          the existing  system of supplying  additional  air  into  the
          intake manifold,  thus metering of  the air is achieved.

          "An accelerator  valve  directly  coupled into the carburetor
          throttle  valve  controls the  flow  of  fuel alcohol.   The
          opening  and  closing  of  the   accelerator   valve  is   in
          conjunction with the opening and  closing  of the carburetor
          throttle   valve.    Likewise,   fuel  metering  is   achieved.
          Openings  are  adjusted  in  accordance with engine types  and
          displacement,  also bearing in mind  the fuel to  air  ratios
          of the type of  alcohol utilized."  A drawing  of  the system
          is provided in Figure 1 of  the Attachment B.

-------
         (5)   "Manner of Operation  -  Basically,  the  system  of operation
              is on  the basis of dual  fuel simultaneously  fed  into the
              combustion chamber  in  vaporized  form.   The  conventional
              carburetor supplies  gasoline  in vaporized  form into  the
              combustion chamber in the usual manner.  The  alcohol fuel
              is vaporized  thru this novel system of vaporization whereby
              the heated air  combines  with the  fuel, and  subsequently
              combines with gasoline, both of which  fuels are  in  vapor
              form.   They combine at  a  point just  before  the combustion
              chamb er.

              "The   device   therefore    uses    two   kinds    of   fuels
              simultaneously,  using two fuel  tanks independent  of each
              other  using their respective fuel pumps,  filters,  and pass
              thru  a metering  device  that  proportionately  meters  the
              desired percentage  of  fuel  passing  thru it.   The  alcohol
              system follows  the following sequence in liquid/vapor  flow;
              From the fuel tank, the fuel passes  thru the electric fuel
              pump which forces the  fuel to flow to the engine, then thru
              a filter,  the proportioning  valve,  the accelerating valve,
              the vaporizing  chamber,   and  into the  intake  manifold  in
              vapor  form."

4.  Product Installation,  Operation, Safety  and Maintenance  (as supplied
    by Applicant);

    a.   Applicability:

         (1)   "In view  of  the  systems utilization of  the  stock  parts  of
              the motor  vehicle,  virtually  all  gas-driven  gasoline
              engines can be  provided with  the  device."

         (2)   "The only  inhibiting factor would involve the engine having
              no PCV valves.   In such a  case,  the  installer  can make use
              of such valves  provided  for in the kit,  and  install same in
              the same manner  and form  as indicated  in the  installation
              manual.

              "The kit cones  in two  sizes;

              Type A - From,  1,000 cc to 3,000 cc engines
              Type B - From 3,000  cc to  10,000 cc engines"

    b.   Installation -  Instructions, Equipment, and Skills Required;

         (1)   Device Installation  - General Instructions;

              (a)  "Installation  of  the  alcohol fuel tank  in  the trunk  of
                  the motor  vehicle or  in any suitable place  beside  or
                  opposite the  fuel  tank  of  pick-ups and  trucks.   In
                  which case,  the alcohol fuel  tank  should  be strapped
                  securely in  the chassis in a manner similar  to that  of
                  the conventional gasoline  fuel tank."

-------
(b)   "The  electric  fuel  pump  should   then  be  installed
     beside the fuel  tank,  preferably  in  the  lowest  level
     of   the  fuel  tank  immediately  preceded  by  an in-line
     fuel  filter.   The  level of  the  electric  fuel  pump
     should not be higher than 2 feet from the lowest level
     of  the fuel tank."

(c)   "The proportioning  valve shall then be  installed  in a
     readily accessible place  in  the  engine's  firewall.
     The alcohol  fuel line  should  be  in  series  with  the
     alcohol valve and  the  same  series  installation should
     be  made with the gasoline fuel  line.  The  cuts in the
     fuel line should be carefully made and  connected  with
     supplied  rubber   connectors."   A  drawing   of   the
     proportioning valve  is provided in  Figure  2 of  the
     Attachment B.

(d)   "From  the  proportioning  valve,  the alcohol fuel  line
     proceeds to the  accelerating valve or solenoid valve.
     The   accelerating   valve  should   be  installed   in
     conjunction with  the  accelerator  pedal.    The action
     should  be the  same as  the  action   of  the  throttle
     valve.  When the accelerator  pedal is  depressed,  the
     connecting action  on  the accelerator should  open  the
     throttle  valve  of   the carburetor.   The  same action
     should  govern   the  opening   and  closing   of   the
     accelerating  valve, which is  normally  connected to the
     carburetor by  a  bracket  normally connected  to  the
     carburetor bolts in  the base of the  carburetor.   The
     suitable and  recommended installation  is as follows:"
     A  drawing  of  the   accelerator  valve and  linkage  is
     provided in Figure  3 of  Attachment B.

(e)   "Vaporizing Chamber  -  Most gas-driven  motor  vehicles
     are provided  with an orifice in the intake manifold of
     the. engine.  In  such  a case,  the  plug  is  removed  and
     the vaporization chamber  is installed  in  its place.
     Where  such an orifice is not present, the  PCV line is
     connected  in  the  intake manifold,  the PCV   line  is
     removed and  the  vaporization  chamber is installed  in
     its place.   The PCV  line  is  then   provided  with  a
     connector  that  is then connected in the  air  inlet  side
     of   the  vaporization  chamber."    A   drawing   of   the
     vaporizing  chamber  is   provided  in  Figure  4   of
     Attachment B.

(f)   "The heat  exchanger is then  attached to the exhaust
     pipe,  in  the closest  and most convenient  place  after
     the exhaust manifold.  The PCV  line  [is]  connected  by
     a tee  connection from  the air  cleaner  line,   is  then
     attached to the inlet side of  the  heat exchanger.   The
     exit side  of  the heat  exchanger is  connected to  the
     vaporization  chambers'   air  inlet  side.   Please  refer
     to   the  following  diagram."   A  drawing of  the  heat

-------
          exchanger and heated  air  system is provided  in Figure
          5 of Attachment B.

(2)  "Tools required for installation.

     "In addition  to  the  usual complement  of  small tools  that
     most  mechanics  are  provided,  a  set  of   tube  flaring  and
     cutting tools should be added."

(3)  Equipment required to check accuracy of installation.

     (a)  "Vacuum gauge.   0 to 30  negative  pressure and  from  0
          to 5 psi.

          "The  vacuum  reading  should  be  taken  prior  to  the
          installation of  the  vaporization chamber.  The vacuum
          gauge may be tapped  to  the vacuum  line  of  the  brake
          booster  and  a  vacuum  reading  taken.   Subsequently,
          another   reading   should   be    taken  following   the
          installation of  the  vaporization  chamber.   If only  a
          small  drop  is  shown in  the  reading,  for  instance,
          between 1 -2 atm.  [psi] then the  reading  is  normal.   A
          greater amount of  drop  shows a leak  in the  system and
          all fittings and connections should be checked.

          "On the positive pressure test of  the vacuum  gauge,  to
          test the  fuel  line,  the  electric  fuel pump  should  be
          activated.  After bleeding the  system free of  all  air,
          and a  consistent  pressure drop  takes place,  then the
          fuel line should be checked  for leaks.

     (b)  "Flowmeter - to check" the  rate  and flow of the fuel.

     (c)  "Pulse  Indicators  -  All  electric   fuel  pumps   are
          provided  with   pulse   indicators  connected   to   the
          contact point  and  each  opening   and closing  of  the
          contact point  is  transmitted  to  an  electric  bulb  or
          LED  in  the   instrument   panel.    Depending   on   the
          distance of  the electric  fuel pump to the  vaporization
          chamber,   each pulsation  can  be  calibrated  in  each
          vehicle by measuring the  fuel volume  by cc  in relation
          to  the  pulsation  of  the   electric  fuel  pump."   A
          drawing of the wiring diagram  is given in Figure  6  of
          Attachment B.

(4)  "Adjustments to the  Vehicle  or Vehicle Systems  as  well  as
     the Device Following the Installation.

-------
              (a)  "The  flowmeter  should  be  attached  to  the  gasoline
                   line.   The flowrate  should  then  be  monitored  at  a
                   point  just before  the  red-line*  of  the  tachmometer
                   (while the vehicle is  in motion).   After  the flowmeter
                   is disconnected,  the  flowmeter  should  be attached  to
                   the alcohol fuel  line,  and  the alcohol flow should  be
                   adjusted to 30%  of the  gasoline flow rate  previously
                   taken a point close to the  red-line of the  tachometer.
                   The  adjustment  should  be  made  on the  proportioning
                   valve, at which point  the accelerating valve should  be
                   inoperative.

              (b)  "The accelerating valve  should  be set in  such a manner
                   that  the  metering valve should  be closed  at  idling
                   speed.  It should  only start  to open at  approximately
                   1/10 of the total throttle linkage travel.

              (c)  "The   electric   micro   switch   should    be   similarly
                   adjusted.   It should  only activate  at  a  point  1/10  of
                   the total throttle linkage travel.

              (d)  "The   idling   air  should  be   slightly   closed,   to
                   compensate  for   the   additional  air  from  two   PCV
                   valves.   The   distributor  may  likewise   be  slightly
                   advanced  to   take  advantage   of  the  anti-detonation
                   characteristics  of  alcohol.    Generally upwards   of
                   about  2 degrees  BTDC  can be  added  depending  upon  the
                   engine type and condition.

              (e)  "The  system will  still  work  effectively  even without
                   modifying  the  distributor."

         (5)  Skills Associated with the  Installation of the  Device

              "A  skilled  mechanic  with  some  knowledge  of   electrical
              wirings and the use  of  the  vacuum gauge  and  flowmeter.
              Most  'week-end' mechanics   with  moderate knowledge of  the
              above skills should likewise be able to manage."

    c.   Operation;

         "After  the  engine has  sufficiently  warmed  up,  the  system  is
         activated by putting the power switch on,  in  the control box and
         which control  box is normally  placed in  a  convenient  place  in
         the instrument panel.

         "This  activates  the   electrical   system  which   involves   the
         electric  fuel   pump,  accelerator  switch,  and  the   pulse  (fuel
         flow) indicator.
*Maximum allowable rpm recommended by the engine manufacturer.

                                                                        10
     "At idling speeds and very  low  RPMs,  the system is not activated
     and only  the  normal gasoline flow  takes place.   Once  the  pedal
     is depressed, to place  the  vehicle  in motion and at accelerating
     or  cruising   speeds,  the   alcohol  system  is  activated.   When
     decelerating or idling,  the system is automatically deactivated.

     "The heated air  entry  into the intake manifold  is automatically
     regulated  by  the  PCV  valves  additionally   installed  or  is
     normally  provided  in  the stock system.   At low  intake  manifold
     vacuum  pressures  (as when  accelerating  or at  cruising  speeds)
     more  air  is  admitted  into the system.   At  high vacuum  inlet
     manifold  pressures, (as when idling)  very little air  is  admitted
     into the inlet manifold.

     "The amount  of  air admitted  into  the  inlet manifold  therefore
     varies  in  accordance  with  vacuum   pressures   and   is   fairly
     efficient air metering  device,  standard  in most  motor  vehicles
     today.

     "The  bleeding  of  additional  air  into  the   inlet   manifold
     (together with additional alcohol fuel)  likewise  reduces  the air
     flow  thru the carburetor  and  reduces  the  supply of  vaporized
     gasoline  extracted  from the  carburetor  in proportion with  the
     orifice size in the inlet manifold  and  the  amount of  air  passing
     thru the orifice.

     "Before putting  out the  engine,  the alcohol  system should  be
     deactivated.   However,  no  harm can  take  place  even  if it  is
     inadvertently forgotten to be switched off."

d.   Effects on Vehicle Safety;

     "The  only possible  hazards  involving  the use  of  the device
     involve  the  escaping fumes of  leaking  alcohol  from  the  fuel
     system.   The  human  body's  tolerance to alcohol  fumes  can  be
     considered   non-hazardous    unless    alcohol   in  considerable
     quantities is spilled  in a  sealed  and  non-ventilated  passenger
     compartment.    In  which  case,  dizziness  can  occur.    Such  a
     possibility is however  remote  as  the fuel  system does not  pass
     thru the  interior  of  the motor vehicle  [but]  along  the  chassis
     [to where  the]  proportioning  valve is attached  to the firewall
     of the engine side.

     "The air  fuel system  [is]  contained in sealed  lines,  none  of
     [these] components expose the alcohol  fuel to the atmosphere."

e.   Maintenance:

     "Post  Installation check-up should be made  within 15  days or 500
     kms. whichever comes first.   It  will involve the following:

          Schedule I  - Check  for any  air  or fuel  leaks
          Schedule  II  -  Check  for  the   proper  operation   of   the
          electric fuel pump

-------
                                                                          11
              Schedule III - Check for any  clogging  of  the fuel jets and
              clean same if necessary
              Schedule IV  - Check fuel  filter  and  clean  if  necessary.
              Check calibration of  alcohol fuel  rate.
              Schedule V  -  Check  proportioning  valve  and  accelerating
              valve for clogging or leaks and correct.

         "Recommended Maintenance Schedule of the Device:

     "Every 30 days             Every  90 Days           Every 120 Days
      or 1,500 Kms.             or  3,000 Kms.           or 4,500 Kms.

5.  Effects on Emissions  and Fuel Economy (submitted  by Applicant);

    a.    Unregulated Emissions;

         "Virtually  all  pollutants,  HC,  CO and even  NOx  are  reduced.
         Even while  low grade alcohol  is used  (160  proof),  the efficient
         vaporization  resulting  from  the combination  of  finely  sprayed
         fuel with heated  air  (120 degrees  [celsius] plus)  reduce water
         vapor  in  even  less   quantities   than  those  emitted  in  the
         operation of the automobile without the device.

         "The only  [problem that a] malfunction in  the  supply  of alcohol
         will [cause is that it will]  simply deactivate the entire system
         (malfunction of  the electric  fuel pump)."

    b.    Regulated Emissions and Fuel Economy;

   •'     No data  was provided  with the  application.  Limited  data  were
         supplied with the  applicant's  response, Attachment E,  to EPA's
         request for additional  information, Attachment D.

6.  Analysis

    a.    Identification Information;

         (1)   Marketing  Identification;   In  section  2a  the  applicant
              identified    the    device  as   the   "Dynamix"    (Alcogas
              device/system).    In  the  cover   letter   accompanying   the
              application,  the  applicant also  referred  to the  device as
              the  "Dynamix  (alcohol/gasoline   add  on   device)".    The
              applicant's  response,   Attachment  E,  to   EPA's   initial
              request for  additional  information included test data  for
              this device identified  as "Alcogas dual flow device".   All
              three  identifications are  variations   of  the name for  the
              same device.

              A related product  for diesel  engines  was also referred to
              in  the  information  submitted   on   the   gasoline/alcohol
              device.  This diesel/alcohol  system was referred to  as  the
              Powerflo (alcodiesel  device)   and  the  alcodiesel dual  flow
              device.  No  description  of this   diesel/alcohol device  was
              provided.

-------
                                                                        12
     (2)  The  applicant  stated  in  Attachment  E  that  an   intake
          manifold adapter is provided when  necessary  to ensure  that
          the  alcohol  entered  the manifold  at  the  center.   Since
          there  are  many  different  configurations  of  carburetor
          bases,  several different  adapters  (and  thus model numbers)
          would be required.  Therefore,  the marketing identification
          of the device is judged to be incomplete.

     (3)  Inventor and  Patent Protection:   The original application
          did not include a copy of the patents.  After  reviewing the
          application,  EPA requested,  see Attachment D, a copy  of the
          Republic of  Philippines  patent  no.  13218 and U.S.   Patent
          application covering the device.  The applicant's  response,
          Attachment  E,  did not  include  a  copy  of the Republic  of
          Philippines patent.   The  applicant  provided  no response  to
          a  subsequent  request,  Attachment  F for  this  patent.  The
          only U.S.  patent information supplied  was  a  copy  of  the
          filing  document  for  the  U.S. Patent  (Attachment  A).   This
          document provided no  drawings  or  detailed  description  of
          the device.

     (4)  Applicants   The  applicant was  identified in Section 2c  as
          Mr.  Jose Ma.  R.  Concepcion.   However,  all  correspondence
          received  from   the  applicant   was  on   stationery   with  a
          Tricontech   Inc.  letter  head.    Mr.  Concepcion1s  position
          with Tricontech Inc. was not stated nor is there indication
          of this company's connection with the  device.

b.   Description;

     (1)  The primary purpose  of the  device  is  to allow  a vehicle  to
          efficiently operate  on  a  blend  of  gasoline   and  hydrous
          ethyl  alcohol.   The important  feature  of  this device  is
          that the alcohol does  not need  to be water free since it  is
          introduced  in a vaporized form  and  the alcohol is  contained
          in a separate fuel system.  Normally,  vehicles  operating  on
          a liquid fuel blend of gasoline  and ethyl alcohol  must use
          water-free  alcohol  to  prevent  phase  separation  (the water
          will separate out of the  alcohol/gasoline mixture) and the
          problems associated with having liquid  water  in  the fuel
          system.  The alcohol may also attack parts  of a  standard
          fuel system.

          The applicant  also  stated  in  Section  3b that the   device
          would allow a vehicle  to  operate on a much  wider  range  of
          fuel combinations -  from  only hydrous  ethyl alcohol to only
          gasoline.    EPA  asked   the  applicant  (Attachment  D)   if
          vehicles had been successfully  operated  over  a wide range
          of fuel proportions  and with what  alcohols.   The   applicant
          replied    (Attachment    E)    that     vehicles   had    been
          satisfactorily   operated  with  a wide  range  of  gasoline/
          hydrous ethanol blends,  but  that the engines  stalled  during
          prolonged idle  when  operating only with 160 proof ethanol.

-------
                                                                  13
     EPA  also  asked  the  applicant  (Attachment   D)   if   other
     alcohols  could  be  used.    Since  the   applicant   did  not
     respond to this question, it  is not  known if   the  device  is
     able to operate properly with other  alcohols.

(2)   The  theory  of  operation given  in  Section  3b adequately
     describes  the  problems encountered with the use   of   a
     gasoline/ethyl  alcohol   fuel  blend  and  the   approach  the
     device takes to overcome these problems.

(3)   The description of the  device given in  Section 3c  does  not
     adequately describe the Dynamix device.   The description  of
     the major components  of the system is only given in general
     terms.   However,   a   detailed  description  of  the   major
     components  was not  provided.   EPA's  request  (Attachment
     D & F)   for  more   details   of   the   proportioning   and
     accelerating  valve  was only  partially  answered by  the
     applicant's one technical reply (Attachment E).

     The   description   of   the   proportioning  valve   is   not
     sufficient to show that  is  is actually  able to function  as
     claimed.  The  description does not  specify how the  device
     is able to control  the flow  of  gasoline to be  a   fixed
     percentage  (i.e.,  flow  ratio) of the alcohol  flow and  how
     this flow ratio is readily adjustable by  the operator.

     The  description  of   the  "accelerating  valve"   was  also
     inadequate.   Although it was  called an  accelerating  valve,
     it appears  to  be more  properly an alcohol  flow control
     valve that  is opened and closed by  the throttle  linkage.
     It  does  not   replace   the   function  of  the  carburetor
     accelerator pump.  The  functioning  of  this valve is also
     questionable.    The  linkage  adjustment  procedures   instruct
     the installer to  adjust  this  valve so that it is   shut  off
     at idle and  is open  at engine  red-line (while  in   gear)
     sufficiently to control  the alcohol  flow to  be the desired
     alcohol/gasoline  fuel  ratio.    Therefore,  the  alcohol flow
     is controlled  to  be  a function  of  throttle  position  only,
     regardless  of  engine  load,  whereas,   in  an  unmodified
     engine,  gasoline  flow is controlled to  be  a  function  of
     both load and  rpm.   Thus the  engine  could  have either  too
     much or too little of this gasoline/alcohol blend  under all
     operating conditions.

     An  additional  problem  is   that  the  normal   supplemental
     carburetor  circuits   (idle,   accelerator  pump,  and   power
     enrichment)  probably  will not  function normally due to the
     reduced flow of gasoline and  air into the carburetor.   The
     device  appears  to  have no   means   to   incorporate   these
     necessary auxiliary  carburetor functions into the alcohol
     system.   The  applicant  did  not respond  to  EPA's   requests
     (Attachment D  & F) for this  additional information.

-------
                                                                       14
          The applicant  also states  that  "...  the  increase  in
          alcohol fuel  makes up  for  the  energy  lost by  gasoline.
          However,  quick and easy  accelerating  valve  adjustments  are
          necessary  to effect this  condition."   (Attachment  E)   This
          implies that  problems in  obtaining   the  proper amount  of
          fuel are  readily  overcome  by  the driver.   However,  since
          this valve  is mounted   under  the  hood,  the  operator  is
          unable  to  readjust   the  fuel  flow  to  current   driving
          conditions while operating  the  vehicle.

          The vaporized alcohol is introduced at  any  convenient  hole
          in  the intake manifold.    This  will  cause  uneven  fuel
          distribution to the various cylinders  if either  the hole is
          not centrally  located or  there is  uneven  mixing of  the
          vaporized  alcohol  and  gasoline.  EPA  asked the applicant  to
          comment  on  this  mixing   problem   (Attachment D).    The
          applicant's  response  indicated that  he was  aware of  the
          problem and  now  uses a  carburetor base  plate adapter  to
          allow the  vaporized alcohol to be  introduced  at the center
          of the intake manifold (Attachment E).   This approach  will
          tend to make  the  fuel mixture more uniform.  However,  the
          applicant  submitted no  information that  showed that  good
          mixing  and distribution actually occurred.

     (4)  The device is  claimed to permit  an existing  vehicle to  be
          modified   to  operate  on  a  combination  of  alcohol   and
          gasoline.   However,  there  is no  data  that   showed  that
          modified   vehicles  had performed  satisfactorily in  normal
          usage.

     (5)  The cost  of  the  device  plus  installation  is  not  known.
          EPA's  request for  cost  information (Attachment  F)  was  not
          answered.   Due to  the lack  of  specific details about  the
          device, EPA  is also  unable to estimate  the cost   or  time
          required for  installation of  the device.

c.   Installation, Operation, Safety  and  Maintenance:

     (1)  Applicability;

          The  applicability  of  the  product,   as   stated   in   the
          application,   to   essentially  all  gasoline  vehicles   is
          questionable.   Necessary  carburetor baseplate adapters may
          not be made  for  all  vehicles.  Also,  the  fuel  injection
          systems of most fuel  injected  gasoline vehicles would  not
          function   satisfactorily   with  these  reduced gasoline  flow
          rates.

     (2)  Installation  -  Instructions, Equipment and Skills Required:

          The installation  instructions for the device provide  a
          generalized  but reasonably complete description of  how  the
          device  is  to  be  installed.   However,   there   are  several
          major problems  not  addressed.

-------
                                                                  15
     The device may not contain all the necessary components  and
     parts.   EPA asked the  applicant  if  the accelerating  valve,
     electric  fuel pump,  heat  exchanger,   carburetor  adapter,
     hoses,    fittings,   wiring,    etc.    necessary   for    the
     installation were provided  with the device  (Attachment  F)
     but received  no   response.   If  these  components  and  parts
     are not  provided,   the  installer  would  have  to   have  a
     working knowledge of  the system  and  expend   considerable
     effort   to  acquire  the required  parts and  to  insure  all
     components are compatible.

     As stated  only "...  the  usual  complement of  small  tools
     that  most mechanics  are provided..." would be  required  for
     the  installation.   However,   the   proper  adjustment  will
     require a fuel flowmeter  and  possibly  the  use  of a  vehicle
     chassis dynamometer  (Attachment  E).   A fuel  flowmeter  is
     not a normal mechanic's tool and a chassis dynamometer is  a
     very  expensive piece of specialized  testing equipment.   Few
     mechanics  would even have  access  to  these necessary  items.

     The adjustment procedures 4b(3)(a)  require the engine fuel
     flow  to  be  measured  at  engine  redline  while  in  gear.
     Besides  the   safety   hazard   and   potential  for   engine/
     transmission damage  this presents,  it would be difficult  to
     obtain  the necessary measurements.   The applicants  response
     to EPA's  concern  about the  safety  of this  procedure  was
     that  the procedure had been modified.  The applicant  stated
     that  he now  measures the  flow  rate  with  the  vehicle on  a
     chassis   dynamometer  and,   by  doing   this   for  many
     representative  vehicles,   has   developed  a   table   of
     recommended flow  rates for a given  application.    However,
     the applicant  did  not provide  this  table  of recommended
     settings  or  provide  the  revised   adjustment  procedures.
     Even  if  this  table  were  available  it  might  not cover  an
     individual's  vehicle  model   or  specific  combination   of
     vehicle  and  powertrain.    Therefore  an  installer   would
     either   need  access   to a  chassis  dynamometer  or  have   to
     revert  to  the potentially  unsafe  road procedure.

     The applicant  understates  the   skill  level and  knowledge
     required to  install the  device.   Proper  installation  and
     adjustment of the  Dynamix  device will require above  average
     mechanical skills  plus  a  good understanding of  the  theory
     and operation  of  the device.   It is unlikely  most  weekend
     mechanics  or  many professional  mechanics  will be  able  to
     properly and safely  install and adjust  the  device.

(3)  Operation;

     The operation  of  the system presented  by  the  applicant  in
     Section 4c  is  that it  is  only necessary  to  switch  the
     device  on, after  starting and  the engine  is  warmed up,  and
     then  off  prior to   turning  the engine  off.   However,   in
     practice,    operation   of   the   system   would    require
     considerably more  operator attention.

-------
                                                                   16
     Since a vehicle with the device is dual  fueled  and will use
     large amounts  of  ethyl alcohol, the  operator will need  to
     provide storage  and handling  for  the alcohol  since it  is
     unlikely to be located at a nearby  service station.

     The system does not provide an  alcohol fuel  gauge.  Since a
     considerable amount of  alcohol  would  be  burned  and  running
     out would cause the engine  to  stop,  a fuel  gauge  should  be
     provided.

     A feature of  the  system is the ability  to choose  different
     proportions of alcohol  and  gasoline.   Although  this  can  be
     accomplished by adjusting  the  control on the  proportioning
     valve,  to  maintain a  correct  overall  air/fuel ratio  the
     accelerating   valve   linkage   would  also   need   to   be
     readjusted.    The  user would  have  to  develop  the data  to
     determine  the  proper  new settings.   These   adjustments  can
     only  be performed  when the  vehicle  is parked since  the
     proportioning  and accelerating  valves  are  in  the  engine
     compartment.

(4)  Effects on Vehicle Safety;

     In Section  4d, the  applicant  identifies  some of the  safety
     hazards associated with the device and properly  notes these
     identified  hazards  are  minimal.   However,   he  overlooked
     several hazards that are more  serious and much  more  likely
     to occur.

     Use  of  the  device will  require  large  amounts  of  ethyl
     alcohol.  Unless  alcohol is available at a service station,
     the operator  of  the vehicle will  need  to provide for  the
     safe  storage  and handling  of  large  amounts  of  a  highly
     flammable  liquid.

     The   routine   maintenance   checks  will  require   partial
     disassembly  of  the  alcohol   fuel   system   in   the   engine
     compartment, thus  presenting another  safety hazard.

     Finally,  the  installation adjustment  procedure   requires
     that  the  vehicle  be  operated  at  engine redline  while  in
     gear.   Exceeding  this  engine   rpm  could  lead  to  engine/
     drivetrain  damage.   Also,   since  it  may  be  necessary  to
     perform  this  adjustment   procedure   on  the   road  while
     monitoring   other  system parameters,  this procedure  could
     cause accidents.

(5)  Maintenance;

     The maintenance schedule given  in  Section 4e  is judged  to
     be  adequate.   However,  checking  the  items   required  will
     require partial  disassembly of the  system.   Since  these
     maintenance  requirements occur quite  frequently,  every  30
     days or 1500 kilometers, the vehicle operator will  probably

              need to be  able  to perform, many of  these  checks.   Checking
              the required  items  will require average mechanical  skills,
              a working knowledge of  the device, and  the  usual  complement
              of mechanic's small tools.

    d.   Effects on Emissions and Fuel Economy;

         (1)  Unregulated Emissions;

              The applicant  submitted no  test data  and made  no  claims
              regarding unregulated  emissions.  The  statements given  in
              Section 5a relate to regulated emissions only.

              An EPA  sponsored  study  (1)  showed  that aldehyde  emissions
              were relatively unaffected by  the  use of gasohol  (gasoline
              with 10%  ethyl alcohol).  Also,  there  were no  significant
              quantities  of  ethyl  alcohol observed  in   the  exhaust.   A
              similar  result could  be expected  for   the  Dynamix  device
              when operating with  a  10%  alcohol  concentration  if  the
              device  functions  as  stated and  is  properly matched  to  the
              vehicle.  The  effects  on unregulated emissions are  unknown
              when    operating    the   device    with   higher    alcohol
              concentrations since  vehicles  tested with  higher  alcohol
              concentrations normally have  had engine  modifications.

         (2)  Regulated Emissions and Fuel  Economy;

              The applicant  did not submit test  data  in accordance  with
              either   the   Federal  Test  Procedure  or  the  Highway  Fuel
              Economy Test.   These  two  test  procedures  are the  primary
              ones recognized by  EPA for  evaluation  of  fuel economy  and
              emissions for light duty vehicles(2).

              The test  data which was  submitted  consisted  of  a  limited
              amount  of fuel economy data  for  passenger cars on  the road,
              steady  state passenger  car and  light  duty  vehicle tests  on
              a chassis dynamometer,  and a heavy  duty engine dynamometer
              test (Attachment  D).    This  data did not  substantiate  the
              fuel economy  claims  for  the  device.   Although  emission
              benefits were claimed,  no supporting  data were  supplied.
(1)  "Gasohol,   TEA,   MTBE,   Effects  on   Light   Duty  Emissions,"   EPA
460/3-79-012

(2) The requirement for test data following these procedures  is  stated in
the policy  documents  that  EPA sends  to each  potential  applicant.   EPA
requires duplicate  test  sequences before  and after  installation of  the
device  on a minimum of two vehicles.   A  test  sequence consists of a  cold
start  FTP plus a HFET or,  as a simplified  alternative, a  hot start  LA-4
plus a  HFET.   Other  data  which have  been collected  in  accordance  with
other   standardized procedures  are  acceptable  as  supplemental  data  in
EPA's  preliminary evaluation of a  device.

-------
                                                                          18
              The  applicant   was  advised   of  our   requirement   that
              applicants  submit   appropriate .test  data  to  substantiate
              their claims.  He was reminded of the  test  requirements  and
              our  obligation  to  publish the  results  of  our  evaluation
              (Attachments C,  D,  G, H,  I,  and  J).  Although he was  given
              adequate time to comply, no further data or  information  was
              provided.   Therefore, our evaluation was  completed  on  the
              basis of  the information  available and  EPA's  engineering
              judgement.

              EPA  has  performed   only  a limited  amount  of  testing with
              gasolines  containing ethyl alcohol.   For  'gasohol', a  blend
              of 10% ethyl alcohol in gasoline, EPA's test  program  showed
              that  the  expected  result  would  be  higher   evaporative
              emissions, lower hydrocarbon and carbon monoxide  emissions,
              and  poorer   fuel   economy  (3).   However,   because   the
              applicant  failed to provide  valid test  data or an adequate
              description of his device, it is impossible  to determine  if
              the Dynamix device  would  perform  in a similar manner.   The
              device  uses  a  wide  range  of  ethyl  alcohol  to gasoline
              ratios,  is  able to use  hydrous  ethyl alcohol,  and  uses  a
              different  fuel induction system.

7.  Conclusions

    EPA  fully  considered  all  of  the  information  submitted  by   the
    applicant.  The evaluation of the  Dynamix  device was  based on that
    information.

    The  information  supplied  by  the  applicant  was   insufficient   to
    adequately  assess  if  the  device  would  mechanically  function   as
    claimed.   The  applicant  failed to  respond  to  repeated requests  for
    this additional information.

    The  limited  fuel  economy  test   data  supplied were  inconclusive.
    Although  emission benefits  were   claimed,  no  supporting  data were
    supplied.    The  applicant  was advised  by  letter and  by telephone  on
    several  occasions  of  EPA's  requirement   that  applicants   submit
    appropriate test data  to  substantiate  their claims.   Although  he  was
    given  adequate time to  comply,  no  further  data or information  was
    provided.    Therefore,  our evaluation was  completed  on  the basis  of
    the information available  and EPA's engineering  judgement.

    The  installation  and adjustment,  operation,  and maintenance  of  the
    Dynamix device will  expose  the   installer  or  operator  to serious
    safety hazards.
(3) "Gasohol Test Program",  EPA Test  and Evaluation Branch report  79-4A.
Part  of  the  decrease in  fuel  economy  is  due  to  the  fact  that ethyl
alcohol has a lower energy content than the gasoline  it displaces.

                                                                             19
    The  installation  of the  Dynamix device  on a  vehicle  would  require
    many hours  and need to  be done  by  a  skilled mechanic who  has had
    specialized  training.    Specialized   tools   and  equipment  would   be
    needed for the post installation adjustments.

    The  applicant's concept  of modifying  vehicles to operate  on a dual
    fuel system appears to be a potentially viable  approach for operating
    a vehicle on a combination of gasoline and  ethanol.  However,  without
    a detailed  description  of the device  or  valid supportive  test  data,
    there is  no technical  basis to  support  any claims  that  the  Dynamix
    device  improves   fuel  economy,  reduces  emissions,   or provides   an
    acceptable method of using an  alternate fuel.

Mr. Jose Ma. R. Concepcion

Republic of the Philippines
Dear Mr. Concepcion:

We have received  your  application for an EPA  evaluation of the "Dynamix"
device.  Our  Engineering Evaluation  Group  has  reviewed  your application
and has  identified several  areas that require  additional clarifications
prior  to  further  processing  of  your  application.   The questions  are
listed below .according to the section numbers of your 511  application.

1.  Section III,  B, Patent  Protection.   We  ask  that  you  submit  a  copy of
    RP patent 13218 and  the U.S. patent application.

2.  Section VIII  Description of the device

    A.   Section  VIII,   A.  states  the  device  normally  operates  in  the
         recommended proportions  of  30%  alcohol to  70% regular gasoline.
         Is  this  30% alcohol  the 160 proof  hydrous alcohol  mixture,  or
         does  this  mean the alcohol  content  in the  hydrous  alcohol mix-
         ture is  in a ratio of 30% pure alcohol  to gasoline?
B.
C.
D.
     Section VIII, A. states regular  gasoline
     country use unleaded gasoline.
                                                     Most vehicles in this
         Section VIII, A.  states  that  a  wider  range of proportions can be
         used,  including  only alcohol and  only gasoline.   Have modified
         vehicles  been  successfully  operated   only   on  gasoline?   only
         alcohol?  which alcohols?  what range of proofs (water content)?

         Section  VIII,  C.  states   the  proportioning valve  meters  the
         desired  percentage  of   fuel  passing  through  it.    By fuel,  I
         presume you mean  gasoline.  That  is,  the  amount of gasoline flow
         is controlled  to  be a preset ratio  of the  hydrous  alcohol flow
         rate   (normally   70%  gasoline  to  30%  hydrous  alcohol).   The
         alcohol  flow is  controlled  solely  by  the   alcohol  accelerator
         valve.  Is this correct?
    E.   Details of the proportional valve and its controls are needed.

    F.   The  device appears  to  restrict the  flow of  gasoline  to  a  set
         percentage of  the  alcohol  being consumed.   It appears that under
         most  driving  conditions,  the  carburetor  float bowl will  not be
         full  and  in  fact may be  relatively empty.   If  this  is correct,

-------
                                                                           27
                                   -2-
         the  carburetor,  idle  circuits,   accelerator  pump,  and  power
         enrichment  circuits  will  not  function   properly.    There  is
         apparently  no   function  in the  alcohol  circuits  to   take  over
         these functions.  Is this correct?

3.  Section  IX,  F.  shows  the  vaporization   chamber   located  in  any
    convenient orifice  in the  intake manifold  or the manifold  PCV  hole.
    It appears  that this would not  give  an identical homogenous  mixture
    of  air,  hydrous alcohol  and  gasoline  to  each  cylinder  for  most
    vehicles.  Please comment and provide data.

4.  Section X, I.  states that  for  adjusting  the device and  vehicle,  the
    gasoline flowrate is taken "at a point  just  below  the  red-line of the
    tachometer  while   the   vehicle  is  in  motion".    This  adjustment
    procedure  is  unacceptable.   It  would  require  the  vehicle  to  be
    operated at maximum speed  for an extended  period  and thus  present  a
    safety hazard.

If you  are able  to visit EPA  when you come  to North  America early  in
November, we could  discuss  the questions listed in this  letter.  If you
can not come to EPA, we would  like  to  receive answers to  these questions
by mail by the first of November.

I am  enclosing  our  latest policy documents  related to  the  evaluation  of
fuel economy and emission control devices.

    Mr.  Merrill W.  Korth
    Device Evaluation Coordinator
    United States Environmental Protection Agency

    Dear Mr.  Korth,

         Hereunder please find the answers to your queries contained in
    your letter dated Sept.  30, 1981.

    1.   Attached please find a photocopy of the Notice of Allowance from
        the US Patent Office relative  subject application and referred to
        as application no.  115,616 labelled and attached hereto as Annex A.
        The consolidated and amended claims are contained in the US patent
        which my lawyers in Washington DC should have by now.  I have ins-
        tructed them to mail you a copy.

    2A.  This  refers to 30%  of 160 proof hydrous ethanol to 70% gaoline.

    2B.  For purposes of this application, we shall refer to unleaded gasoline.
        Reference must however be made to tests with leaded gasoline in RP.

    2C.  "Modified" vehicles run normally with pure gasoline.  The same vehi-
        cles  run satisfactorily when in motion and at cruising speeds with
        160 -nroof ethanol.   However Engine stalls occur at prolonged idling
        speeds when operating with only 160 proof ethanol.

    2D.  Your  observation is correct, the alcohol flow is controlled by the
        accelerating valve,  after maximum proportions are preset by the pro-
        portioning valve.

    2E.  Attached please find the details of the proportional valve referred to
        as Annex B.

    2F.  The proportioning valve does restrict the flow of gasoline at such points
        where the flow of alcohol is increased sicne the metering valves are dia-
        gonally opposed. This is particularly true when cruising at proportions
        exceeding 50% hydrous alcohol  to gasoline.   In such a case, when gasoline
        fuel  starvation take place,  the increase in alcohol fuel makes up for the
        energy lost by gasoline.   However,  quick and easy accelerating valve ad-
        justments are necessary to effect this condition.

        The overiding principle in the device is to operate at preset proportions
        such  as 30% hydrous  alcohol  to 70%  gasoline and operate on pure alcohol
        or liberal  proportions thereof on rare but  necessary occassions when there
        is no gasoline.

         Item:   Likewise,  when the intake air is  bled  thru  the  device orifice
         in the intake manifold,  there  is a proportional  drop in  carburetor
         air velocity which in this case is compensated by  the  alcogas device/
         system infusing both heated air and alcohol fuel thru  said orifice.   It
         is reasonable to  presume therefore that  becasue  of lessened vacuum pres-
         sure and air velocity passing  the gasoline carburetor, that a sonse-
         quential reduction of gasoline fuel would take place.

         The orifice size  of the  intake manifold  therefore  would  enable a  given
         engine to operate efficiently  only at certain parameters,  that, is why
         it is  recommended that for most applications, a  20% to 30% hydrous
         alcohol to the equivalent gasoline proportion is recommended.  On the
         basis  of fixed and present proportions,  this  factor alone  may even set
         aside  the mechanical manipulations in the proportioning  valve.  This,
         plus the fact that alcohol contains oxygen, which  gasoline does not  have.

     3.   You must be referring to the need to effect a fairly equal distribution
         of air and fuel alcohol  to all the cylinders.  This is not a problem
         when the orifice  is located in the center of  the intake  manifold.  Most
         of the popularly  sold cars in  the PHILIPPINES (RP)  have  the orifice  in
         the center of the intake manifold.   Whenevsr  the orifice in the intake
         manifold is not centered,  we provide an  adapter  immediately under the
         carburetor containing an inlet orifice for the device to effect a more
         equal  distribution .of fuel alcohol  and heated air  to all the cylinders.

     4/   There  would be a  safety  hazard at top gears,  but we normally take this
         at the lowest gears.   STill, you have a  point, irregardless if the moni-
         toring is being taken at crawling sppeds at low  gear.  We  have since,
         amended the procedure by priorly dterming proportions on chassis  dynos
         on as  many representative cars and recommending  the desired flow  rate
         for a  given application.


         Certainly,  considerable  improvements can still be  effected,  such  as  mo-
     nitoring and computerizing fuel and air deliveries in  relation to varied
     engine loads and speeds.   Please allow me to respectfully aver however,  that
     the  worldwide concern involves survival considerations in utilizing economi-
     cally  feasible alternatives.   The  socio-economic  implication in suitable
     alternatives such as  cheap alcohol involving and  affecting the grain  interests
     (corn,  wheat,  manioc,  sugar,  etc.  feedstocks) plus the capability of  distressed
     governments to reduce crude  oil dependence has now assumed survival conside-
     rations.   Incidentally,  several top oil company executives have expressed
     satisfaction over this 30% hydrous alcohol compromise.  The  device can be
     further improved to exceed this recommedded  proportions but  the imperatives
     of international business require  a concept  of l£ve  and let  live.

Mr. Jose Ma. R. Concepcion
#30 Melantic Street
San Lorenzo Village Markate
Metro Manila
Republic of the Philippines
Dear Mr. Concepcion:

We have received  your  letter of October 19,  1981  in which you  responded
to our  request for  additional information on  "Dynamnix".  Our  Engineering
Evaluation Group  has reviewed  your  response  and  has identified  several
areas that still  require additional clarification  prior  to further  pro-
cessing of your  application.  Again, our questions are  listed  below  ac-
cording to the section numbers of your  511  application.

    1.   Section  III,  B, Patent  Protection.   We  ask that you  .submit  a
         copy of RP patent 13218.

    2.   Section VIII,  Description of the Device.

         A.   Section VIII,  A,  your reply  (2C)   referred  to  160 proof
              ethanol.    I therefore  assume  your  device  has  not   been
              tested with other alcohols nor  is it meant  to be  used  with
              other  alcohols.   Is  this  assumption  correct?   Your answer
              also appears to imply  the  vehicles  do not  start and accel-
              erate  properly  when operating  on  only 160  proof  ethanol.
              Is this assumption correct?

         B.   The  drawings  of  the  proportioning   valve,  provided as an
              attachment to  your  letter, do  not  adequately describe  the
              valve  and  its  manner  of  operation.    Please provide a more
              detailed description of  the  valve and its method of   con-
              trolling  the flows of ethanol  and gasoline.

         C.   Your  reply  (2F)  stated  "However,  quick and  easy  acceler-
              ating  valve  ...".  I  presume  the accelerating  valve  here
              referred  to  is  the  alcohol  accelerating  valve.   Is   this
              assumption  correct?    The  function   of this  accelerating
              valve  appears  to  be  to replace part  of the engine's basic
              fuel requirement.   Since  the  normal  supplemental carburetor
              circuits  (idle,   accelerator  pump,   and power   enrichment)
              probably will not function normally  due to the reduced flow
              of  gasoline  and  air  into  the  carburetor,  how  are these
              supplemental functions performed  by  the alcohol   acceler-
              ating valve.

                                                                           31
         D.   Your reply  (2F)  states "On  the  basis of fixed  and  present
              proportions,  this  factor  alone  may  even  set  aside  the
              mechanical manipulations in  the proportioning  valve.   This,
              plus the  fact  that  alcohol contains  oxygen, which gasoline
              does  not  have."   The  meaning  of   this  statement  is  not
              clear.  Please  describe more  fully  what is  meant by  this
              statement.

         E.   Your reply  (3) states  that  mixture  distribution  is  not  a
              problem when using the  orifice located at the  center  of the
              intake manifold.  Please  provide  data or other  information
              to support this statement.

    3.   Section IX, Device Installation

         A.   Your reply  (3)  refers  to  a  carburetor  adapter.   For  which
              makes/models/years  of  vehicles  sold in the  U.S.  do  you
              provide adapters?  Is the  appropriate adapter  supplied  with
              the device?   Which  makes/models/years of  vehicles sold  in
              the U.S. can use the device without  an adapter?

         B.   Your  reply  (4)  states you  have modified  the  recommended
              installation  adjustment procedures.  What  are  the  propor-
              tions  recommended  for  each  make/model/year  of  vehicle?
              Please  list.   Does  the  installer  simply  dial  in  this
              value?   Are  adjustments   required   to  be  performed  on  a
              chassis   dynamometer?   Are   road    adjustments   required?
              Please provide a  copy of  the current installation instruc-
              tions as provided with  the device.

What is the suggested retail price of Dynamix?

What  parts are  supplied  with  the  Dynamix device,  e.g.,  accelerating
valve,  electric  fuel  pump, heat  exchanger, carburetor  adapter,  hoses,
fittings, wiring, etc.

Again,  I  welcome the  opportunity to personally  discuss  these  questions
with  you  if you have  the opportunity to  visit EPA in November.  If  you
cannot  come to EPA,  we would like  to receive  answers to these  questions
by mail by December 4th.

    Dear Mr. Concepcion:

    We received  your letter  of  October  19,  1981 in which you responded to our
    request  for  information on  your  "Dynamix"  device.  As  I  noted in  my
    letter of November  19,  1981  (copy enclosed) we  still  require additional
    information   prior  to  further  processing  of  your  application.   Please
    provide the  requested information immediately.

    The Environmental Protection Agency is  obligated  to expeditously process
    your application.  However,  the information you previously submitted  does
    not adequately  describe your device and does not  include  valid test  data
    following the  proper  EPA test procedures.   The  limited  information  you
    provided does not show a benefit  for your device. Therefore,  we presently
    have  insufficient   technical   information  to  adequately  evaluate  your
    claims for the  device.

    Unless I  receive  a satisfactory response  by February  5,  1982,  we  will
   •complete  the evaluation of  your  device  using  the  information  that  is
    currently available.

    Again, . I  welcome  the opportunity  to  answer your  questions  and  to  work
    with you in designing a  test  plan  to  test your device  at  an independent
    laboratory here in the United  States.   However, I will  need the requested
    information  to  efficently assist  you.

    Please contact  me  immediately  if  you  do not  understand  this  course  of
    action.

Dear Mr. Concepcion:

We received your telegram  of  February  1  in which you stated  that  you  had
just learned of our request for information on  "Dynamix" as  contained  in
our recent two letters.  You  also  indicated  that  you  had  not  received  the
actual request contained in our letter of November 19, 1981.  Although  a
copy of  the  letter of November 19 was  to be enclosed with the letter  of
January 11, apparently you did not receive it.   I  am therefore  enclosing
a copy of both these letters.

Your telegram also  stated  that you expect to return  to the United States
in March  to  run tests on  your device.   Again,  I welcome  the opportunity
to answer  your  questions  and  to  work with you  in  designing  a test plan
for  testing  your  device  at  an independent laboratory  in this  country.
However, I will  need the requested information  to  efficiently assist  you
and ask  that you  respond to my letters  of November 19 and January 11  by
March 19.

Because of the  problems  we have had with the  mails,  please  notify me  by
telegram as soon as you receive this letter.

Dear Mr. Concepcion:

I am enclosing copies  of  three  letters  that we sent to  you  previously on
November 19,  1981,  January 11,  1982, and  February 11,  1982.   During  our
telephone conversation on March 25 you  did  not  seem to recall what corre-
spondence you had received from EPA.

We are discouraged  that you  have  not been able to  respond to our letters
nd answer our questions, especially the questions posed in our letter date
d November 19.  Your application for an EPA evaluation of your device dates
 back to September 10, 1981 and we have made no significant progress.

We are considering  completing our  evaluation  with the  information at hand
at this point.  In that situation, you  could  reapply at  a later date whan
you will be  nearer  to the point  of  developing scientific data  to demon-
strate the effectiveness  of  your  device.   I would be  happy  to comment on
the suitability of your test plans at any time.

Please let me know if you have any questions concerning these actions.

Dear Mr. Concepcion:

We still lack  several  critical pieces of information  before  we can prop-
erly  evaluate  "Dynamix".   As  explained  in  our earlier  letters and tele-
phone  conversations,  we are  obligated to  publish our  evaluation  in the
Federal Register.   We  cannot delay that  action indefinitely.  Therefore,
I  am  forced to complete our  evaluation and publish our conclusions with
the information at hand.

The most important  information we lack  is  substantive  test  data to sup-
port  your  claims  for the device.  We  have  yet to see your  test  plan for
the test  program you are  about to initiate.   As we explained,  if we do
not have  the  opportunity  to  review  your plan,  you run  the  risk  of an
oversight  that might  invalidate your  whole  effort.   We  recognize that
such  testing is expensive  and want to ensure  that your  testing will meet
our needs.

The other  important  pieces of  information  are the details  of  the device
description and  installation instructions.   We originally requested  that
information in our  letter  of November 18 and  have reiterated the  request
in subsequent correspondence.

Because of  the  inordinate  amount of  time that has passed  since  we first
received your  application  and the  difficulties encountered in getting the
information in proper form  for us  to  analyze,  we  are  faced  with  the need
to establish a deadline.  That  deadline  is  May 21.  At that time, we will
conclude our  evaluation,  with  or  without the  requested  information.   We
believe  that  that  date allows more  than enough  time  for our review of
your  plan  and  the conduct of  the  test program at an  independent  labora-
tory.  At  least  three  vehicles should be  tested.   If  the data  from the
independent  laboratory  indicate  a meaningful fuel economy or  emission
benefit, EPA will perform  confirmatory  tests  even though you may  not wish
to fully disclose the detailed  description of  your device.

Please  let  us know  when you send  us the  test  plan what  laboratory you
have selected and  the  scheduled  dates for your  testing.   If  you have any
questions  about  these   requirements,  please  contact me   immediately  at
