STATUS OF INDUSTRY PROGRESS TOWARDS ACHIEVEMENT OF THE 1975 FEDERAL EMISSIONS STANDARDS FOR LIGHT-DUTY VEHICLES

The report presents a compilation and assessment of all available information pertaining to the technological progress made by the automotive industry toward meeting the 1975 Federal emission standards for light-duty vehicles. Important findings and conclusions are presented in the Highlights and Executive Summary sections of the report. Material related to candidate 1975 emission control systems is given in Section 2. An assessment of emission control techniques and system components (engine modifications, EGR (exhaust gas recirculation), oxidation catalysts, thermal reactors, and secondary air supply) is presented in Sections 3 through 7. Engineering emission goals and emission control system deterioration characteristics with mileage accumulation are discussed in Section 8. The interim standards proposed by the automobile manufacturers are summarized in Section 9 and maintenance, cost, safety and production lead time aspects are briefly discussed in Sections 10 and 11. Section 12 presents a brief status report of unconventional automotive engines, including the rotary (Wankel), diesel, gas turbine, stratified charge, Rankine cycle, and Stirling cycle.
