SYSTEM AND PROCESS FOR PREDICTING AND PREVENTING PRE-IGNITION

A process and a system for preventing pre-ignition in an internal combustion engine (ICE). The process includes providing an ICE that has a combustion chamber and an exhaust. Also provided is a total hydro-carbon (THC) sensor in communication with the combustion chamber. The THC sensor senses a THC...

Zusammenfassung:	A process and a system for preventing pre-ignition in an internal combustion engine (ICE). The process includes providing an ICE that has a combustion chamber and an exhaust. Also provided is a total hydro-carbon (THC) sensor in communication with the combustion chamber. The THC sensor senses a THC level of the combusted gas for a given combustion cycle i (THCi) of the ICE. In the event that THCi is greater than a reference THC level (THCref), a pre-ignition countermeasure prior to an immediate subsequent combustion cycle i+1 is executed. Furthermore, the executed pre-ignition countermeasure prevents pre-ignition from occurring in the immediate subsequent combustion cycle i+1 of the ICE.
