The laser Rayleigh scattering method was applied for the time history measurements of local gas temperatures in a methane-fueled spark-ignition engine. Transient temperatures were measured at three different points in the combustion chamber under various operating conditions of the engine. Results showed that the gases at the respective points were subjected to nearly the same temperature history with the highest temperature just after flame arrival, followed by gradual decrease as the process proceeded. A simulation model, which was developed to predict gas temperatures under the relevant engine operations, revealed that the temperatures measured corresponded fairly well with the predicted ones. The Rayleigh scattering method was found to be an effective means of time- and space-resolved temperature measurement in an actual engine.
