Effects of Combustion Chamber Design on Combustion in Spark Ignition Engines 821578

ABSTRACT

Combustion chamber design, through its strong influence on the rate at which energy is released during combustion, plays a key role in determining engine performance. To aid in understanding the effects of chamber design, the link is established, first, between energy-release rate and critical performance parameters such as efficiency, emissions, power stability, tolerance to dilution, roughness and knock. Design approaches are then explored for controlling the energy-release rate. Supplementing these general approaches is an examination of the effects of specific design features on energy release and engine performance. Finally, a number of contemporary engines incorporating these design features are reviewed.
