摘　　要：针对发动机实际喷油时间相对于计算喷油时间超差这一现象,从混合气浓度闭环控制理论出发,对产生这一现象的诸多原因进行了分析和归纳。阐述了喷油量超差现象与发动机真空控制系统泄露之间的联系,并由此提出一种新的真空控制系统故障诊断方法。Aimed at the ultra difference phenomenon of engine injection quantity, we carried out analysis and induction on a lot of causes of this phenomenon according to the theory of closed cycle control, expounded the relationship between injection quantity and engine vacuum system. A new method for vacuum system malfunction diagnosis is brought forward.
