Impact of A/F Ratio on Ion Current Features Using Spark Plug With Negative Polarity

摘要

The increasing interest and requirement for improved electronic engine control during the last few decades has led to the implementation of several different sensor technologies. The process of utilizing the spark plug as a combustion probe to monitor the different combustion-related parameters such as knock, misfire, Ignition timing, and air-fuel ratio have been the subject of research for some time now.
