摘要
本文研究了喷油嘴针阀头部形状变化对ZH110 5单缸直喷式柴油机性能的影响 ,研究表明针阀头部形状变化对柴油机低速大转矩工况的烟度与燃油消耗率影响明显。通过对油束动量和活塞燃烧室积炭情况的分析 ,揭示了针阀头部形状变化影响柴油机性能的原因。
The influence of the needle tip shape change on ZH1105 diesel engine is studied in this paper. The experiment results show that the different shape of needle tip make a remarkable influence on the smoke emission and fuel consumption of engine at low engine speed and heavy load. Through the analysis of fuel spay instantaneous momentum and carbon laydown in combustion chamber, the reason that the shape of needle tip influence on engine performance has been illustrated.
