Highlights
Aftermarket Retrofit Device
Evaluation Program
The U.S. Environmental Protection Agency (EPA) conducts a program
to evaluate the effects of fully developed aftermarket devices on vehicle
emissions and fuel economy. Participation in this program by
manufacturers of devices is voluntary. EPA evaluations of engines,
retrofit devices, emission control devices, and related products are
conducted for the purpose of keeping policy makers, technical
personnel in government and industry, and the general public abreast of
developments in the field of automotive fuel economy and pollutant
emission control.
Background
Aftermarket fuel additives and devices advertised to increase vehicle fuel
economy and/or reduce vehicle emissions may claim to have EPA
approval. EPA, however, does not approve, certify, endorse or register
these products.
EPA evaluates aftermarket fuel additives and devices on a voluntary
basis when an application is accepted from the company which manufac-
tures the product. The Agency may also evaluate a product at the direc-
tion of the EPA Administrator or the Federal Trade Commission. Results
of any evaluation are a matter of public record and are published in the
Federal Register. All preliminary independent laboratory and EPA
laboratory costs for a voluntary evaluation are paid for by the company
offering the product. The evaluation program is restricted to fuel addi-
tives and devices and does not apply to oil additives and lubricants.
A minimum evaluation program employs the same type of scientific tests
used by EPA to certify vehicles for sale in the United States. These are
the Federal Test Procedure (FTP) and the Highway Fuel Economy Test
I Printed on Recycled Paper
-------
(HFET). Both involve controlled driving
patterns on a laboratory test machine (a
dynamometer) which similuates an actual
road load condition and during which
exhaust gases are captured and analyzed.
Fuel economy for city and highway driving
(FTP and HFET, respectively) is calculated
using a carbon balance formula and the
actual emission samples results which are
the same methods used for calculating the
city and highway fuel economy informa-
tion displayed on windows of new vehicles.
EPA tests are conducted under very con-
trolled conditions in a laboratory to elimi-
nate uncontrollable variables such as
individual driving habits, wind, weather,
traffic and road conditions experienced
with actual driving on roads. The make,
model and year of vehicles used in an
evaluation are selected to represent typical
vehicles for which the device or additive is
intended to be used.
EPA has evaluated over one hundred
products in this program. A listing of the
products which have been tested (as of this
publication's date) is attached to this
document. The report number associated
with each of the evaluated products may be
used to purchase a copy of the report.
Orders for the reports may be placed with:

It is suggested that individuals contemplat-
ing the purchase of these products request
test data rather than testimonial or anec-
dotal evidence from the supplier. One
should also weigh the cost of the product
against the actual fuel savings over the
intended use period.
The test vehicle's engine is first adjusted to
the vehicle manufacturer's specifications
and tested in this configuration to provide a
base line. In the second stage the product is
installed on the vehicle and the test is
repeated. In the third stage the product is
removed and the vehicle is reset to the
original configuration of the first stage to
determine whether use of the device af-
fected original performance. Duplicate
tests are conducted for each of the vehicle
configurations.
EPA engineers report their findings based
on the test data. The report is then pub-
lished in $\Q Federal Register. Individual
copies of a test evaluation may be pur-
chased from the National Technical Infor-
mation Service (NTIS).

(1) Indicated a statistically significant improvement in fuel economy without an increase in exhaust emissions although cost effectiveness
must be determined by the consumer for his particular application.
(2) Indicated a statistically significant improvement in fuel economy but with an increase in exhaust emissions. According to Federal
Regulations, installation of this device could be considered tampering.
(3) Reduced carbon monoxide and hydrocarbons on older emission control technology vehicles.
