Abstract: The processes of ignition and combustion of a diesel engine are affected by temperature distribution formed during compression stroke. We present an applied study on the measurement of temperature distribution in the swirl chamber of an IDI engine using the Moire deflection technique. The method for determining the quantitative temperature distribution from detected Moire fringe shift has been established. From the measured temperature distribution, the evaporation and air mixing processes in the swirl chamber during compression stroke is analysed and discussed. The temperatures mapped by Moire deflectometry are compared and validated with the temperatures measured by hot-wire anemometry at several representative points. The experimental investigation opens up a new means for measuring the temperature distribution in the combustion chamber of IC engines.
