燃烧室结构形状对柴油机经济性和排放的影响

Effect of the Chamber Form and Structure on Combustion Emission

对于直喷式柴油机来说，燃烧室结构形状直接影响到燃烧室的气体运动及燃烧过程的进行．最终影响柴油机的经济性和排放性能．本文从小型直喷式柴油机的燃烧过程出发，通过试验对比．结合缸内燃烧放热过程的计算，分析探讨了三种燃烧室结构形状对燃烧放热及柴油机性能的影响，为设计开发新产品提供一定的参考依据．

This paper is aimed at combustion and emission of D. I. engine. The effects of the chamber form and structure of D. I. engine on conbustion and emission are analysed and discussed by calcutation of the combustion process and comparision of the experimental measurements, thus the refrence basis is provided for reasonably organizing the combustion and reducing the emission of NOxof D. I. diesel engine.
