• The frequency of a sound wave is changed from the original one by passing through the rapidly temperature changing gas. The new technique for measuring the varying gas temperature by detecting the frequency change of the passing ultrasonic wave was applied to the temperature measurement of combustion gas in a four cycle reciprocating engine. For the check of the measured temperature using this new technique, the measured sound velocity was compared with that by the conventional direct sound velocity measuring method. As a result of the experiment, it was concluded that the new measuring technique was reliable.
