In this paper, based on the specific CNG engine parameters and characteristics, the influence of the injection timing, ignition energy and lean combustion for the engine is tested, in order to explore the control rules of fuel injection, ignition energy and lean combustion and then draw the following conclusions: small injection advance angle of electronic controlled injection CNG engine is optimum

文章根据天然气发动机的具体参数和特性，探索电控喷射CNG发动机在燃料喷射、点火能量和稀燃等方面的控制规律，确定最优的控制参数，开展了喷射定时、点火能量及稀薄燃料等参数对发动机性能影响的试验研究工作，并根据试验结果分析，得出了以下结论：电控喷射WT615CNG发动机燃料喷射提前角要小些为宜

In order to reduce the maximum combustion pressure and the NO, emission, it adopts smaller advance angle of fuel delivery. In most conditions, the combustion starts after TDC; the maximum rate of pressure rise, the combustion pressure and the heat release rate are lower; their relevant phases are retarded.

结果表明，为降低最大燃烧压力及NO、排放，小缸径直喷增压柴油机采用的喷油提前角较小，柴油机在大部分工况下，燃烧始点较迟，最大压力升高率、最大燃烧压力较低，其对应相位较迟，放热规律也较低。

By properly using turbocharger,increasing the efficiency of air charge, improving the machining process for the liner and reducing the advance angle of fuel feeding etc, the particles and NOx of improved 4102BZQ diesel engine were reduced so that it can meet EuroⅠemission standard.The develoPMent of Model 4102BZQ improved diesel engine allows the 4-cylinder engine of DCD to meet the emission legislation forced by our country, and extends the life-time of DCD engines, which makes a contribution to the develoPMent of DCD economy and protection of environment.

通过合理匹配增压器，缸盖进气道，提高充气效率、改善缸套加工工艺、缩小供油提前角等措施来降低4102BZQ完善提高型柴油机的颗粒物和氮氧化物，使之达到欧Ⅰ排放标准。4102BZQ完善提高型柴油机的开发，使朝柴四缸机达到了国家强制性排放法规的要求，延长了朝阳柴油机的寿命，为发展朝柴经济和保护环境做出了贡献。

The animal heat is the result of a slow combustion, and disease and death take place when this is too rapid; or for want of fuel, or from some defect in the draught, the fire goes out.

动物的体温是缓慢内燃的结果，而疾病和死亡则是在内燃得太旺盛的时候发生的；或者因为燃料没有了，或者因为通风装置出了毛病，火焰便会熄灭。
