 note = {It is important to measure the temperature of burnt gas and combustion chamber wall surface of a spark ignition engine because of improvement for thermal efficiency in the engine. The engine combustion chamber wall temperature is usually measured by the thin film type of thermocouple. However there are many restrictions for the thermometer to install the engine. In this study, measurements of temperature and heat flux on spark ignition engine combustion chamber wall using infrared rays were developed. At first the calibration was carried out by detecting infrared rays from a material at given temperature with an IR detector. The calibration is the method to obtain a relation of temperature and infrared radiation. As a result temperature of a measuring object was calculated from measured infrared radiations with the obtained calibration curve. Next infrared rays from spark ignition engine wall were measured with the IR detector. At the same time pressure measurement was also carried out with pressure indicator. To eliminate the influence of infrared radiation from burnt gas, a sapphire glass for observation window sprayed black paint was applied. Therefore the measuring object was the outer surface of the black paint on the sapphire glass. Heat flux was calculated to estimate crank angle where heat flux becomes 0 W/m2. On the crank angle combustion chamber wall temperature and burnt gas temperature were equal. The burnt gas temperature was calculated from measured pressure and equation of state for perfect gas. Generally the result of infrared thermometer agrees with the result of heat flux sensor in average temperature. But improvement for response of infrared thermometer is necessary to apply the engine combustion chamber.},
