In the production of internal combustion engines, there has been a move towards the development of high-performance engines with fuel economy, lighter weights and smaller sizes. These trends help to answer problems related to thermal load and abnormal combustion, etc., in these engines. In order to clarify these problems, a thin film-type probe for instantaneous measurement of surface temperatures has been suggested. A method for manufacturing such a probe was established in this study. The instantaneous surface temperature of a constant-volume combustion chamber was measured by this probe, and heat flux was calculated and analysed with a Fourier series. For a thorough understanding of the characteristics of combustion, the authors measured the wall temperature of the combustion chamber and computed heat flux through a cylinder wall while varying the protrusion height of the probe. To achieve the above goals, an instantaneous temperature probe was developed, thereby making possible the analysis of the instantaneous temperature of the wall surface and unsteady heat flux in the constant-volume combustion chamber.
