摘要
针对发动机空燃比开环控制的弊端,分析了空燃比闭环控制内涵与闭环控制方案,给出了空燃比与燃油修正值的关系,研究了燃油修正与发动机控制系统故障的相关性,并结合实例,分析了燃油修正值在油控故障诊断中的应用.
Aimed at defects of open-loop control of the engine air-fuel ratio,the air-fuel ratio closed loop control connotation and closed-loop control scheme are analyzed,the relationship between the air-fuel ratio and fuel correction value is given,the fuel corrected and the power control system failure correlation are studied,fuel correction value in oil control fault diagnosis is analyzed.
