The purpose of the report was to demonstrate a prototype of the atomics International diesel exhaust control system in a Southern California Rapid Transit District bus (a flexible coach equipped with a Detroit Diesel 6V-71N engine). The program objectives were to meet the California 1975 heavy-duty vehicle standards and to establish the economics of the system. Emission reduction objectives were attained except for the reduction of NO sub x. To meet California requirements of less than 5 gm/B-Hp-Hr of combined HC and NO sub x, larger residence times were required. The resulting muffler size may not be compatible with bus installation constraints. Alternative technologies of NO sub x control under development by diesel engine manufacturers may prove to be more cost effective. Advantages and disadvantages of the Atomics International diesel exhaust emission control system (DEEC) in vehicle application are discussed. Recommendations are offered and conclusions reached. Tables and figures are numerous. Appendices include the tabulation of laboratory test data, muffler performance test reports provided by the California Air Resources Board, Air Resources Laboratory, and a market analysis for the DDEC muffler.
