涡流室式柴油机起动孔对燃烧过程的影响

Effect of Starting Throat in Prechamber on Diesel Engine Combustion Process

本文借助于数据采集系统实测的L195型柴油机不同工况下的主燃室和涡流室示功图及计算所得相应的燃烧放热规律,分析了涡流室起动孔对燃烧放热过程的作用护理及其对涡流室柴油机动力性、经济性以及怠速噪声的影响。

By means of data logging system,the indicator diagrams in main andprecombustion chambers for L195 type diesel engine under different workingconditions were recorded and corresponding combustion heat release rates werecalculated.Therefrom,the effect of starting throat in prechamber on combus-tion heat release process,power output,fuet economy and idle noise levelof prechamber diesel engines was analysed.
