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。
Aiming at the defects of the engine air - fuel ratio open - loop control, after analysing the air - fuel ratio closed loop control connotation and closed- loop control scheme, we expound the relationship between airfuel ratio and fuel correction value, and then study the correlation between fuel correction and the engine control system failure, finally analyze the application of fuel correction value used in oil control fault diagnosis.
