EVOLUTION OF A NEW COMBUSTION SYSTEM FOR DIESEL EMISSION CONTROL

The emission control of small naturally aspirated diesels has posed severe problems. The exhaust quality of engines of this type can be improved by reducing the combustion temperatures and/or reducing the initial heat release rate. A qualitative review of the problem led to the evolution of a modified cycle characterized by high turbulence leading to higher air/fuel mixing rates and faster diffusion burning. This "Squish Lip" combustion system allowed CARB 1977 projected emission levels to be met on development engines without performance deterioration. /GMRL/
