System and process for predicting and preventing pre-ignition

A process and a system for preventing pre-ignition in an internal combustion engine (ice) includes detecting an ionization level of a combusted gas from a cylinder of the ice during gas exchange and for a given combustion cycle i. When the ionization level is greater than a reference ionization level a pre-ignition countermeasure prior to and/or during an immediate subsequent combustion cycle i+1 is executed. ... Fev Gmbh
