Based on the engine control principle, from a new visual angle, four kinds of causes of insufficient engine driving force are discussed, the variations of mixture characteristic values and the ignition angles in the fault conditions are obtained, together with a relationship among five parameters in fault conditions, including the injection time of each turn, which increases the correlation of these parameters greatly, and enhances their applicability in fault diagnosis. Based on this method, the locations may be identified where failure may occur., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null,

articleAbstract=发动机动力不足是影响汽车使用性能的常见故障之一。由于涉及供油、点火、怠速、排放等多个子系统，是汽车故障诊断的难点。本文基于发动机控制原理，阐述了发动机动力不足的3类原因，给出了故障状态下混合气特征值和点火提前角的变化规律，建立了每转喷油时间等5项参数的关联模型，使参数与故障的关联度大大增加，增强了参数在故障诊断时的适用性。由此出发，比较全面地分析了可能发生故障的部位，并给出了故障诊断流程。,
