Recently, the regulation of car-exhaust emission has become more and more needed. Due to the regulation, catalyst technologies have made remarkable progresses. Exhaust-gas temperature is one of the important factors in the efficiency of such exhaust systems. The purpose of this study is the development of a new technology to know the exhaust-gas temperature field; that is, the usage of an infrared thermograph by which we measure the heat-radiation energy in proper wavelength ranges of H_2O, CO_2 and CO included in the automobile exhaust gas. This technology has an advantage that we can get real-time temperature-field information without disturbances by sensor probes in the test flow field.
