阐述了直列6缸发动机发火顺序对曲轴扭振的影响,直列8缸发动机的增压特性以及气缸出口排气温度的差异。影响特定气缸排气温度异常升高的因素有很多,但主要是受其他气缸排气压力波的影响,因此进一步分析了压力波的大小与受压力波影响的时间。
The effect of firing order of on-line 6-cylinder engine on the torsional vibration of the crankshaft is expounded. The turbocharged characteristics of the in-line 8-cylinder engine and the difference of exhaust gas temperature at the outlet of the cylinder are described. There are many factors that affect the abnormal increase of exhaust gas temperature in a particular cylinder but are mainly influenced by the discharge pressure wave of other cylinders. Therefore, the time of the pressure wave and the pressure wave are further analyzed.
