The effects of converter position, ignition timing and idle speed on catalytic converter light-off behavior were studied on an electronically controlled LPG injection engine.
研究了电控LPG发动机的催化转化器安装位置、点火提前角和怠速转速对催化转化器快速起燃的影响。
The injection pressure, timing, duration and rate depend on the engine speed and load.
喷油压力、喷油始点、喷油持续角和喷油率均取决于柴油机转速和负荷。
Variable valve train enables the engine to achieve the best valve timing at a very high speed and load. Thus the performance of the engine can be improved.
配气可变机构可使发动机在较高转速和全负荷范围都能得到最佳配气，因而改善了发动机性能。
