Combustion System Optimization for a New SOHC V8 Engine

A systematic methodology for combustion system optimization was formulated for the development of the new Chrysler V8 engine. The methods employed by this process correlated flow bench generated airflow and charge motion studies to dynamometer based measurements of wide-open-throttle performance, exhaust emissions, fuel consumption, and combustion stability. Selection of the optimum combustion system was based on a weighted analysis of dynamometer generated parameters.
