- Measurements of flame temperature and KL factor in a diesel engine by the two-color Method
抄録
The diesel engine has been receiving mounting critical attention for its pollutants emissions. This study aims to measure flame temperature and soot concentration in a diesel engine, and the author designed and built an optical system of the two-color method. Experiments have been conducted using a single cylinder heavy duty diesel engine, and the effects of EGR and fuel injection pressure on in-cylinder flame temperature and KL factor have been investigated. The result show that the radiation intensity from the flame increases first with crank angle due to soot formation and drops later due to soot oxidation, and the level of intensity at a later crank angle correlates well with soot emission value in engine exhaust.
本研究では,最新の高過給エンジンにおいて高EGR 率と高噴射圧力が火炎温度とKL 値の局所値に及ぼす影響を多数サイクルにわたって調査することを目的としている.
