Summary:

The aim of this study was to clarify the feasibility of applying ion current measurement to detect knock and misfire in lean-burn gas engines. The practical applicability was evaluated by conducting a basic test on a small engine and a test on a large engine. The tests were conducted by advancing the ignition timing to cause knocking, and an evaluation was carried out by comparing the knocking intensity detected by ion current signals and by cylinder pressure signals. By increasing the application voltage and including an amplifier circuit, the weak ion current signals were detected, which indicates that it should be possible to use ion current measurement to detect knock and misfire in lean-burn gas engines
