Abstract This report describes the laboratory effort toward reducing emission and fuel consumption in a heavy-duty gasoline engine, while retaining current durability performance. The goals were HC plus NOx of 6.7 g/kW-hr (5g/bhp-hr) CO of 33.5 g/kW-hr (25 g/bhp-hr), a ten percent reduction in specific fuel consumption and 1500 hours of service accumulation, using the procedures proposed for the 1979 model year. The initial laboratory evaluations involved standard carburetors, a Dresserator inductor, a Bendix electronic fuel injection system, exhaust manifold thermal reactors, exhaust gas recirculation along with a number of other engine emissions control components and operating parameters. Based on the project goals and the initial results, a system was selected to undergo final optimization and service accumulation. The system selected consisted of electronic fuel injection, thermal reactors with air injection, exhaust gas recirculation and a high energy ignition system with vacuum advance. This system met the emissions and specific fuel consumption goals and completed 1500 hours of service accumulation. During the last 750 hours of service accumulation, a heavy-duty oxidation catalyst was included in the exhaust system as an add-on to the optimized system. Subsequent to the 1500 hours of service accumulation, this engine was installed into a heavy-duty truck for an evaluation of driveability and performance.
