摘　　要：介绍天然气发动机多点顺序喷射系统的开发研究 ,试验在原F913C柴油机上进行 ,对原机的进气系统和燃烧系统进行了改进 ,采用高能点火。电控系统精确控制点火时刻、燃气喷射量 ,通过三元催化剂控制排放。发动机通过了动力性和排放的测试 ,达到了动力性要求并满足欧Ⅱ排放标准。This paper introduces an Electronically Controlled Multi Point Sequential Injection CNG engine,which is developed on the base of an original F913C diesel engine with optimized induction and combustion system.The high-energy electronic ignition is adopted.The ignition timing and injection quantity of CNG are exactly controlled .The exhaust emission are reduced by a three way catalytic converter.The test result shows that the multi Point sequential injection CNG engine has a good dynamic performance,and the exhaust emissions can meet the Euro Ⅱstandard.
