The pattern of temperature distributions of gases in the combustion chamber of a rapid compression machine and in an internal combustion engine will be complex. And in this report, a successive approximation equation which gives the gas temperature measured by the infrared radiation pyrometer has been derived under the condition of nonuniform temperature distributions. The results agree with the measured temperature and the characteristics of the pyrometer have been investigated with hive model distributions which will occur in the combustion chambers. The pyrometer gives a little higher temperature than the average and the tendency will be more intensified as the ratio of the highest temperature to the lowest departs from unity and temperature levels become lower. The gas near the radiation detector affects the reading more than that located farther apart. Some examples to calculate the peak temperature of the gas in a combustion chamber have been presented.
