Popis:	Premixture combustion mainly occurs in gasoline engines but it had also occurred in diesel engines at the previous combustion. Gasoline engines have been used as marine engines especially for pleasure boats. The mechanism of premixture combustion helps to reduce air pollution and fuel consumption. It also helps to know the mechanism of previous combustion which generates noise and heat loss in diesel engines. This work has studied the effect of flow characteristics to the flame structure during premixture combustion. A constant volume combustion chamber was designed to research the relationships between combustibility and flow characteristics by changing the gas velocity to study its effect on flame shape. Gas velocity was measured by LDV system, combustion pressure was measured by pressure indicator and flame shape was studied by a television camera. The results showed that the main cause of the complexity of flame shape is the turbulence intensity of gas flow.
