Analysis of combustion efficiency is very important for evaluating the engine performance. The components of exhaust gas from the combustor may indicate the behavior of combustion. Therefore, a measurement system of the gas sampling/ chromatographic analysis has been developed under supersonic combustion condition. The components of H2, O2, N2, CO, and CO2 have been obtained under different pressure and temperature of kerosene injection. The results shown the combustion is not uniform, and the average combustion efficiency is around 70%. The further investigation should be carried out to get more details in order to improve the performance.
