United States Air and Radiation EPA420-F-98-033 Environmental Protection October1998 Agency Office of Mobile Sources v>EPA Technical 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: NTIS 5285 Port Royal Road Springfield, VA 22161 (800)553-6847 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).
