汽车正常行驶到滑行阶段发动机喷油量控制研究

Engine Fuel Injection Control Research from Vehicle Normally Driving to Sliding Period

通过对几种汽车的正常行驶到滑行阶段发动机喷油量的测试研究,汽车在正常运行到滑行阶段的过程中,发动机的喷油脉宽的变化情况与汽车的运行状况有很大关系,带档滑行在短距离情况下省油;通过对发动机急加速时的喷油脉宽与正常工作时的喷油脉宽的对比,仅急加速时喷油脉宽变化较大。本研究的测试结果及数据分析有利于指导驾驶员更好的使用汽车,对节约燃料和环保具有很大的指导意义。

According to the research of engine fuel injection control from vehicle normally driving period to the sliding period, the change of engine fuel injection pulse -width is closely related with the driving conditions of the vehicle, and the vehicle sliding with speed will save fuel in short distance. Through the comparison of engine fuel injection pulse - width in emergent aecelerant with that in normal driving conditions, it works out that only in emergent accelerant fuel injection pulse - width has a large range change. This research and data analysis are useful for wiser driving, environment protection and fuel saving.
