The report describes development testing, optimization, and durability testing of emission control systems capable of meeting 1981 gaseous emission standards while maintaining low sulfate emissions. Four emission control systems were investigated (1) oxidation catalyst with air modulation system, (2) high temperature exhaust system, (3) threeway catalyst with feedback carburetor, and (4) threeway plus oxidation with air modulation system and feedback fuel injection. In Phase I of the project, the air modulation system and the threeway catalyst system were selected for optimization and durability testing. The usual gaseous emissions, plus nonmethane hydrocarbons, total cyanide and ammonia were measured on both systems. The oxidation system was operated on a test car for 24100 km and the threeway catalyst system for 32200 km, with emission tests every 8050 km. The durability distance accumulation was halted on both cars because emissions levels exceeded the 1981 standards. In Phase II of the project, a threeway plus oxidation catalyst system was developed, optimized and tested for durability for 64,400 km. During the durability testing, emissions tests were performed every 8050 km.
