The state of heat loss from combustion gas to combustion chamber walls in an internal combustion engine can be evaluated from instantaneous surface temperature of the walls measured by thin-film thermocouples. For this purpose, measurement devices should ensure high accuracy and synchronize with the engine operation. On the other hand, the measurement circuit used needs to be noise-free and quick in response. Furthermore, meaningfully reproductive data must be generated from the data processing device. In this report, the authors' measurement system including all those devices is presented.
