INTRODUCTION

In January, 1976, the Office of Mobile Source Air Pollution Control
(OMSAPC) of the EPA distributed a report on the results of the sulfuric
acid baseline program.  The report contained results of tests on 56 non-
catalyst and catalyst equipped vehicles designed to meet various light
duty vehicle emission standards.  Since that time, EPA-OMSAPC has con-
tinued testing various prototype vehicles with advanced emission control
systems.  This report discusses the results of OMSAPC testing since
completion of the last baseline program report.

Fourteen vehicles were tested for gaseous and sulfate emissions during
this period.  The objective was to further characterize sulfuric acid
emissions from vehicles with technologically advanced emission control
systems.

TEST SCHEDULE

The vehicles were tested on one of two test sequences.   The first seven
cars were tested using the following two day test sequence:

     1.   1975 Federal Test Procedure - Cold Start (FTP)
     2.   Congested Freeway Driving Schedule - Run twice (formerly SET-7)
     3.   Highway Fuel Economy Test Schedule (HFET)
     4.   Congested Freeway Driving Schedule - Run twice (CFDS)
     5.   Repeat 1-4 once on next day

This is the sequence that was used during the baseline program for
sulfuric acid emissions.

Six of the last seven vehicles were tested using the slightly different
test sequence listed below:

     1.   1975 FTP - Cold start
     2.   CFDS
     3.   HFET
     4.   CFDS
     5.   Repeat 1-4 once on next day

The first three tests of the above sequence is the sequence being con-
sidered in the EPA sulfate test procedure development program  aimed at
developing a uniform sulfate test procedure.

One vehicle in this series, the Ford LTD-930, was not tested using
either of the above sequences.  This car was tested as part of a cor-
relation program with Ford.  Therefore, the test sequence used at Ford
was also used at EPA-OMSAPC.  The daily sequence (run twice at EPA) was
as follows:

-------
     1.   1975 FTP - Cold start
     2.   CFDS - run four times
     3.   HFET

In general, the catalyst vehicles were tested using .030 (+ 0.002)
weight percent sulfur fuel.  There was one exception to this.   The  Gould
NOx catalyst was found by the manufacturer to be sensitive to  high  fuel
sulfur levels.  Gould, therefore, requested that TAEB test the two  dual
catalyst vehicles Novas 781 and 711 with a reduced sulfur level gaso-
line.  At the time this request was received, TAEB had already completed
testing on Nova 781 with .030 weight percent sulfur gasoline.   Nova 711
was tested with the gasoline in the vehicle's tank which was reported by
Gould to be .011 weight percent sulfur.  The diesel vehicles were tested
on diesel fuel containing .270 wt percent sulfur.

The series included nine catalyst vehicles, one of which, the Cosworth
Ve'ga-468, had a pelleted catalyst.  The rest of the catalyst test vehicles
were equipped with monolithic catalysts.  The prototype lean burn Fury
Custom-035 was the only catalyst vehicle without air injection.

The other five cars in the series were non-catalyst vehicles.  Four of
these had diesel engines, while the fifth car was a lean burn Toyota
with modified combustion chamber design.  This consisted of a small
side-chamber (a turbulence generating pot) off the side of each main
combustion chamber.  The fuel is ignited at the mouth of the turbulence
generating pot and as the fuel burns, the pressure inside the pot in-
creases.  According to Toyota, this causes a flame torch to project into
the main combustion chamber, giving more complete combustion in much the
same way a stratified charge engine works.

In general, the preconditioning consisted of 1000 miles of modified AMA
operation for pelleted catalyst vehicles and 500 miles of modified AMA
operation for monolithic catalyst vehicles.  Fuel containing 0.030
weight percent sulfur was used for the preconditioning.  This assured
that the catalyst was stabilized for 0.030 weight percent sulfur fuel
and would not give any unusual storage and/or release of sulfur compounds
due to a different fuel sulfur level.  Since pelleted catalysts have a
larger storage capacity than monolith catalysts, more preconditioning
was necessary for the pelleted catalyst vehicles.  Generally, the pre-
conditioning was done under EPA contract on the Dana Corporation test
track in Ottawa Lake, Michigan.  Two exceptions to this rou£ine were
that the two Novas with dual catalysts were not subjected to any special
preconditioning but were tested as received.

The non-catalyst cars received no preconditioning, since stabilization
of the vehicle to a particular fuel sulfur level is assumed to be re-
quired only when a catalyst is present.

Cooling for the cars during the tests was provided by 5300 cfm fans.
Usually, the smaller cars were cooled using two fans placed in front of
the car.  The larger cars were cooled with four fans - one fan on the
driver side at floor level directed towards the rear wheel and fuel tank
and three fans placed in front of the car.  This cooling is more than is
usually used for the FTP.  There has been some concern expressed that
the standard cooling used in the FTP (generally, a single 5300 cfm fan)
may be inadequate for sulfate testing.  OMSAPC plans to conduct further
work to determine the cooling required for sulfate tests.

The Cosworth Vega-468 was equipped with a conventional pelleted catalyst
and pulsed air injection.  The sulfuric acid emissions from this car on
the congested freeway driving schedule were very low (average =1.1 mg/km
(l.fr mg/mi)).

Eight monolithic catalyst vehicles were tested in this series." All but
one (lean burn Fury Custom-035) had air injection.  The results from
this group of vehicles were extremely varied.  The sulfuric acid emissions
ranged from 0.4 to 38.3 mg/km (0.6-61.7 mg/mi) with an average of 15 mg/km
(24 mg/mi) on the CFDS.  This is the level expected for cars of this
type with high exhaust oxygen levels that generally (but not always)
result from the use of air pumps.

This group included two Novas with Gould NOx catalysts and GM pelleted
oxidation catalysts that were designed to give identical emissions.
However, Nova-781 emitted 38.3 mg/km (61.7 mg/mi) of sulfates while
Nova-711 emitted 7.0 mg/km (11.2 mg/mi), or less than one-fifth the
emission rate from Nova-781.  There are several possible explanations
for this wide variation.  The Nova-781 was preconditioned by Gould for
about 3000 miles with 0.030 weight percent sulfur fuel before it was
discovered that the catalyst was sensitive to sulfur.   Nova-711 was
preconditioned for about 200 miles with low sulfur fuel (0.001 weight
percent).  Therefore, Nova-711 probably was able to store more sulfur
when it was tested in Ann Arbor.  Another reason for the higher sulfuric
acid emission rate from Nova-781 is that this car was tested with 0.030
weight percent sulfur fuel, while. Nova-711 was tested with 0.011 weight
percent sulfur fuel.  This situation cannot be rectified by simply
normalizing the results from Nova-711 to 0.030 weight percent sulfur
fuel, since the validity of this numerical manipulation is questionable.
Although the relationship between fuel sulfur level and sulfate emission
rate is linear, as reported by Exxon Research and Engineering (1)*,
the; slope of this line can be extremely variable for different cars.
Therefore, multiplying the sulfate emissions by the ratio of the fuel
sulfur levels may not yield an accurate result, especially over such a
large range (0.011-0.030).

These two cars also showed significant variation in the NOx emissions.
This might have been due to the different types of EGR valves on the two
cars.  Nova-781, which emitted 0.61 g/km (0.98 g/mi) NOx, was equipped
with a backpressure EGR valve.  Nova-711, which emitted 0.39 g/km (0.63
g/mi) NOx, had a dual diaphragm EGR value.
 Numbers in parenthesis indicate reference at end of report.

-------
The two Pintos (537A and. 537B) listed in Table 2 are actually the same
vehicle with provisions for changing catalysts, so that the same car can
be used to test different catalysts.  Pinto-537A was equipped with a
production catalyst made by Engelhard.  Pinto-537B had an experimental
base metal catalyst produced by Union Carbide.  The production catalyst
emitted much higher levels of sulfuric acid (17.1 rag/km vs. 4.0 mg/km),
but the gaseous emissions were lower (0.22, 1.68, 1.18 g/km HC, CO, NOx
vs. 0.51, 2.98, 1.32 g/km HC, CO, NOx) on the FTP.  The Union Carbide
catalyst emitted much less sulfuric acid, but at the expense of some
gaseous emission control.

The Fury Custom-035 was a prototype lean burn vehicle with electronic
spark advance and a monolithic catalyst without air injection.  This car
had a higher sulfuric acid emission rate than is normally seen from
catalyst vehicles that do not have air injection (24.8 mg/km, (39.9
mg/mi)).  This was possibly due to the lean mixture resulting in high
exhaust oxygen levels, and thus higher sulfate emissions.

The two Volkswagen Rabbits in this category were very similar vehicles
with one difference.  Rabbit-318 was a production car with a monolith
catalyst and air pump.  Rabbit-504 was basically the same car, except
that it was equipped with pulsed air injection.  The sulfuric acid
emissions were very low for both vehicles, although a little lower for
Rabbit-504 (1.2 mg/km for Rabbit-318 and 0.4 mg/km for Rabbit-504).
However, Rabbit-504 emitted about seven times as much CO as Rabbit-318
(5.96 gm/km vs. 0.86 gm/km) in the FTP.  This could be a direct result
of the pulsed air injection which gives little air at idle conditions,
and thus, less oxidation of CO.

As previously mentioned, the Ford LTD-930 was tested as part of a cor-
relation program with Ford Motor Company.  This car was equipped with a
monolithic catalyst and air injection.  Table 3 shows the results of the
testing at both EPA-OMSAPC and at Ford.  (The numbers in brackets indicate
the sample size).

The above results indicate an agreement between laboratories considered
to be fair.

Included in this series of tests were five non-catalyst vehicles, four
of which were equipped with diesel engines.  These four diesels de-
monstrated sulfuric acid emission rates ranging from 3.4 to 7.6 mg/km
(5.4-12.2 rag/mi) with an average of 5.7 mg/km (9.1 mg/mi) on the CFDS
tests.  These emission rates are higher than those normally obtained
from non-catalyst vehicles.  This is, in part, due to diesel fuel con-
taining 0.270 weight percent sulfur or about nine times as much sulfur
as the fuel used to test catalyst cars.

The fifth non-catalyst car tested was the Toyota-276 equipped with a
lean burn engine and the turbulence generating pot.  This vehicle de-
monstrated a very low sulfuric acid emission rate (0.3 mg/km) as is
expected from a non-catalyst gasoline-fueled vehicle.

CONCLUSIONS

The data for oxidation catalyst vehicles in the baseline study for
sulfuric acid emission seem to indicate a trend toward higher sulfuric
acid emissions with lower gaseous emissions.(23)  This trend was not
apparent in the series of fourteen vehicles tested since the end of the
baseline program.  The highest CO emitter in the group, the Rabbit-504,
was also the lowest sulfate emitter and conversely, the lowest CO emitter,
the Nova-781, was the highest sulfate emitter.  However, the rest of the
vehicles showed no definite trend.  A possible explanation is that this
group, unlike the baseline study, was composed mainly of experimental
vehicles.  One can speculate that these cars could operate rich during
accelerations and emit high levels of CO, but operate rather lean during
cruise and thus emit high levels of sulfates.  On the other hand, the
control on exhaust oxygen level might be very good and thus the vehicle
would emit low levels of both CO and sulfates.  In general, this study
neither confirms nor contradicts the results of the baseline study.

The results of this series of tests demonstrate that vehicles equipped
with air injected oxidation catalysts emit higher levels of sulfuric
acid than non-catalyst cars.  Sulfuric acid emission rates for these
cars averaged about 15 mg/km (24 mg/mi).

This study also shows that diesel cars emit higher levels of sulfuric
acid than conventional non-catalyst cars, but not as high as oxidation
catalyst vehicles.  The primary reason for this higher level of sulfuric
acid emissions (average of 5.7 mg/km (9.1 mg/mi) is assumed to be that
diesel fuel contains much higher levels of sulfur than gasoline does.
