摘要
气体传感器通过对空燃比的反馈控制达到改善汽车性能、节约燃料和降低排放的目的,已经成为内燃机控制系统不可分割的组成部分。文章介绍了发动机控制系统的发展过程及工作原理,讨论了催化剂转换效率的诊断和监测,并提出了一种新颖的HC转换效率测量方法。
Gas sensors have become an integral component of control systems for I. C. engines to provide information for feedback control of air - fuel ratio to achieve improved vehicle performance and fuel economy as well as decreased levels of emission. The development process and working principle of the engine control sys- tem are introduced. The catalyst conversion efficiency in the diagnostics and monitoring is discussed and a novel HC conversion efficiency measurement method is proposed.
