THE EFFECT OF ENGINE DESIGN PARAMETERS ON COMBUSTION RATE IN SPARK-IGNITED ENGINES

The effect of five engine design factors on combustion rate was determined. Burn time was measured on 17 different engine configurations, each configuration containing different design levels of the five design factors. The effects of burn time on cyclic variation, ignition delay time, rate of pressure rise and emissions were also examined. Decreasing burn time resulted in increased rates of pressure rise and hydrocarbon emissions and reduced cyclic variation and ignition delay time. Reduction in NOX emissions was noted when burn time was decreased while operating was exhaust gas recirculation. /GMRL/
