| Outline of Final Research Achievements |
A compact housing with optical arrangement for interferometry was designed and made. When hot air was flowed in the measurement region suddenly with an air dryer, the temperature obtained from this interferometry system with a line-sensor camera increased faster than that with a thermocouple. The higher response of the interferometry was confirmed. Next, this housing was set between cylinder block and exhaust pipe and history of exhaust gas temperature was measured in one cycle. As a result, when the combustion delayed in a low load, at first the temperature is decreased and thereafter the temperature is increased.
