Abstract

蛍光体の寿命が持つ温度依存性に着目し,高温の固体表面または流体の温度分布測定法を開発した.また,粒子径が数μmの蛍光体をトレーサーとして併用し,共通の画像から筒内速度分布を同時計測する技術を開発した.筒内ガス温度分布計測ではクランク角の変化による温度変化など定性的な変化の傾向を検出することができた.

A purpose of this study is to develop simultaneous measurement of temperature and velocity in-cylinder. In this report, we tried to measure wall temperature distribution using phosphorescence life time method with high speed camera. Its object was confirmation of possibility of this method for adaptation in in-cylinder measurement. And then we tried to measure gas temperature and velocity, simultaneously. As a result, we measured wall temperature distribution and its temperature had good correlation with a change of calculated gas temperature from in-cylinder pressure. We also measured gas temperature and velocity at motoring condition. Its temperature was good correlation with change of calculated temperature.
