摘要

为了在线获得发动机工作过程中气缸内的燃烧信息

并对发动机非正常燃烧进行诊断

在一台点燃式汽油机的气缸垫内对称布置8个离子电流测量电极

来采集发动机正常燃烧与爆震、失火时气缸内的离子电流信号

经分析比较给出了爆震和失火的诊断依据。结果显示:爆震时

气缸垫内4号测量电极测得的离子电流信号的峰值大于1 μA

7号测量电极测得的离子电流信号提前出现且在上止点附近; 失火时

5号、6号测量电极测得的离子电流很微弱

小于0.2 μA

离子电流信号推迟出现且在上止点后30°～40°之间。该结果可为离子电流法获取点燃式及压燃式发动机气缸内不同位置的信息提供理论依据

且方法简单易行、获得燃烧信息全面

可为实现基于离子电流法的发动机电控系统开发提供实验基础。

Abstract

To obtain the information about combustion in cylinder

and diagnose the abnormal combustion

abnormal combustion in a spark-ignition engine is experimentally investigated with ion current method. Eight ion current sensors are located symmetrically in the gasket. The ion current signals generating during normal combustion

knock and misfire are collected

and a diagnostic criterion for knock and misfire is established by analyzing the ion current signals. The results show that when knock occurs

the peak of ion current detected by the fourth ion current sensor exceeds 1 μA

and the ion current detected by seventh ion current sensor is advanced to the top dead center(TDC); when misfire occurs

the ion currents detected by the fifth and sixth ion current sensor are very week(less than 0.2 μA)

and the appearance of the two ion currents are postponed to 30°-40° CA ATDC.
