    • Methods of mitigating the occurrence of a low-speed pre-ignition event in a multi-cylinder internal combustion engine (10), the engine (10) having a computerized engine management control module (70) and an ignition timing module (66) controllable by the engine management control module (70). The computerized engine management module (70) monitors the operating conditions of the internal combustion engine (10) and at certain operating conditions dithers the ignition timing of at least one cylinder (20) of the engine (10) to induce light to medium SI engine knock temporarily. Due to the high temperature, high frequency pressure waves caused by SI engine knock, fuel and/or lubricant related deposits accumulated on combustion chamber components, i.e. top piston land crevices or piston crown, are consumed so that said deposits (60) cannot become a source of pre-ignition
