LPG单燃料发动机电控标定的研究

Research of Electrically Controlled Calibration for LPG Single-fuel Engine

简要介绍了电控单燃料LPG发动机电控系统的组成情况 ,对不同工况下的空燃比、点火提前角及废气旁通阀的开度等进行了实验标定 ,并通过发动机台架试验 ,考察了LPG发动机的总体性能。

This paper briefly introduces the composition of the electrically controlled system of LPG single-fuel engine.Experimental calibrations are carried out to air-fuel ratio,ignition advance angle and aperture of exhaust bypass valve in different conditions.The performances of LPG engine is investigated through engine bench test.A controlling method adopted has some directive meaning to development of LPG single-fuel electrically controlled engine.
