本文首先介绍了在多缸机上进行单缸电控喷油的实验方案 ,包括单缸功率、油耗的测量 ,进气流量的调节等。之后通过实验和燃烧放热分析 ,详细对比研究了预喷射与单次喷射对柴油机燃烧过程的影响。
This paper first introduces the experimental scheme of single-cylinder electric fuel injection in multi-cylinder machine, including single-cylinder power, fuel consumption measurement, intake flow adjustment and so on. Afterwards, the influence of pre-injection and single-injection on the combustion process of diesel engine is studied in detail through experiments and combustion exothermic analysis.
