介绍了通过改进进气系统和燃烧系统,提高2190T天然气发动机性能的研究结果。为了解决2190T天然气发动机两缸工作不均匀的问题,研究成功了稳压进气管,从而有效地消除了两缸空燃比和排气温度差异过大的缺陷。为提高整机性能,解决2190T天然气发动机燃烧速度低,后燃严重和排气温度过高等问题,研究成功了新型两级点火燃烧系统,大大提高了燃烧速度,从而显著地改善了发动机的动力性、燃料经济性和排放指标。新型两级点火燃烧系统,结构简单,工作可靠,维修方便,便于推广应用。
The results of a study to improve the performance of a 2190T natural gas engine by improving the intake system and combustion system are presented. In order to solve the problem of non-uniform working of two cylinders of 2190T natural gas engine, the successful research of regulated intake pipe has effectively eliminated the defect that the difference between two cylinders air-fuel ratio and exhaust gas temperature is too large. In order to improve the overall performance of the 2190T natural gas engine and solve the problems of low burning speed, serious afterburning and excessive exhaust gas temperature of the 2190T natural gas engine, a new two-stage ignition combustion system is successfully researched, which greatly improves the combustion speed and significantly improves the engine power , Fuel economy and emission targets. New two-stage ignition combustion system, simple structure, reliable, easy maintenance, easy to promote the application.
