| Abstract(J) | ディーゼルエンジンの大幅な熱効率向上には燃焼期間中の冷却損失の低減が極めて重要である．この冷却損失メカニズムの解明に向けて燃焼室壁面の瞬時熱流束の直接計測を目的に、高熱効率を狙った超高筒内圧(３５MPa)条件で使用可能な小型熱流束センサーの開発を行ったので、その概要と得られた結果について報告する． Translation |
| Abstract(E) | Cooling loss reduction during combustion period could be an essential measure for further improvement in thermal efficiency of diesel engines. Direct measurement of local and instantaneous heat flux at various points of the in-cylinder surface will play an important role to reveal detailed mechanism of the cooling loss phenomena. However, there have been very limited number of studies with state-of-the-art engines. This paper reports the outline of a newly-developed thin-film-thermocouple type heat flux sensor, which can be fitted anywhere and is durable under very high in-cylinder pressure (up to 35MPa) aiming higher thermal efficiency, and achieved results by the sensor. |
