Recent research on the design of the combustion chamber of gasoline engines has been focused on lowering exhaust emissions and fuel costs. As the investigation of the combustion process can reveal the major variables of engine performance and the exhaust emission system, much attention has been paid to the formation of the initial flame nucleus and the evolution of the flame thereafter. And the combustion characteristics of an engine are determined by the thermo-chemical conditions, and are determined by the geometrical characteristics of the combustion chamber, the chemical characteristics of the incoming fuel-air mixture, and the flow conditions of the fuel-air mixture flowing into the combustion chamber. If we understand the inter-relationship between these conditions and the combustion characteristics well, we will be able to achieve the optimization of engine combustion.
