An experimental and theoretical study was carried out of mixture formation process in the combustion chamber of a gas engine. The planar laser induced fluorescence technique was applied for the measurement of the concentration distribution in the combustion chamber in the case that the fuel is injected continuously in the intake port. The effect of the state of the inlet mixture on the mixture formation process was investigated. The measured results show that the in the case that the fuel and air mixing is insufficient in the intake port, the fuel concentration distribution at the last stage of the intake stroke becomes less uniform. A three dimensional numerical analysis was applied for the prediction of the fuel concentration and velocity distributions. The calculated results also show that the mixture formation process in the combustion chamber is affected by the fuel and air mixing behavior in the intake port.
