Interesting method and technology for controlling ignition timing by using the spark plug as a sensor when it’s not firing. Delphi Ion Ignition
Performance Advantages
With Delphi's Ion Sense technology, the conventional spark plug acts as an intrusive sensor in the cylinder to obtain information about each combustion event with minimal influence due to environmental conditions such as vibration, mechanical noise, and temperature. Optimized individual cylinder knock control helps increase engine efficiency and reduce fuel consumption. Through Delphi's Ion Sense technology, misfire detection is OBD II capable and provides very high reliability and robustness compared to many other detection methods. Advanced features of Delphi's Ion Sense Subsystem, such as compensation of combustion due to fuel variation, are also available to help reduce cold-start HC tailpipe emissions.
