甲醇柴油双喷射柴油机性能及燃烧研究──甲醇柴油喷射间隔时间对性能及燃烧的影响

A Study on Methanol -Diesel -Dual -Fuel Injection Engine Performance and Its Combustion

本文通过对甲醇柴油双喷射柴油机在甲醇柴油不同喷射间隔时间的燃烧过程、性能和排放等方面实验研究分析，表明甲醇柴油不同的喷射间隔时间对甲醇柴油双喷射柴油机的指示热效率、燃烧稳定性和ＨＣ的排放有大的影响，并指出可以通过调整甲醇柴油的喷射间隔时间来改变燃烧规律，降低ＮＯｘ的排放。

With the experimental study of of the performance, combustion process, emission etc. of the methanol -diesel -dual - foel eugine,the paper shows that under different injection interval time of methanol and diesel, it is shown that different injection interval of methanol and diesel has much more effect on the indicated thermal efficiency and combustion stability and HC emission of methanol - diesel - dual - fuel injection engine. It also points out that the combustion regularity can be changed. NOx emisson can be reduced by adjusting the injection interval of methanol and diesel.
