Recently, the growing concern over the exhaust emissions, cooling requirements and design of exhaust system devices has led to the study of the instantaneous heat transfer rates in the straight portion of the engine exhaust port and the port itself. In this study, experimental measurements were made of the instantaneous exhaust gas temperatures and the instantaneous wall surface temperatures at four different positions in the exhaust port for a range of engine operating conditions. The calculated instantaneous heat transfer rates and the instantaneous heat transfer coefficients were found to be significantly dependent on the geometrical position in the exhaust port, the engine speed and the engine load and depicted a consistent trend in the results.
