Abstract: 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

Abstract: A method for identifying a lubricant composition that reduces the propensity for knock in an engine. The lubricant composition is mixed with a solvent to reduce the viscosity of the lubricant composition, thereby forming a lubricant-solvent mixture having a viscosity similar to or less than that of engine fuel. A sample of a lubricant-solvent mixture is then subjected to a constant volume combustion test to determine the reactivity associated with the lubricant-solvent mixture. The test is repeated for a range of lubricant-solvent ratios, and statistical methods are used to calculate the reactivity of the lubricant composition without solvent.

Abstract: The present disclosure relates to lubricant oil compositions formed from base stock oils to optimize internal combustion engine performance. Base stock oils are identified that have selected cetane number characteristics and relatively reduced reactivity to improve their associated combustion characteristics and reduce engine knock without the need to modify the engine fuel or engine parameters such as compression ratio and/or ignition timing. The base stocks may specifically include esters of dicarboxylic acids, esters of trimellitic anhydride and/or alklyated naphthalene compounds.

Abstract: A method of preventing a pre-ignition event within a cylinder (20) of a spark ignition engine (100) involves taking in-cylinder measurements and using the measurements to determine the instantaneous heat being released within the cylinder (20) as a function crank angle. If significant heat is being released before the intended spark timing, additional fuel is injected into the cylinder (20) immediately following the detection of early heat release (pre-ignition) within the same engine cycle, preferably within 45 crank angle degrees following the detection of pre-ignition. The additional fuel quenches the heat released within the cylinder (20) to prevent a pre-ignition event.
Abstract translation: 一种防止火花点火发动机（100）的气缸（20）内的预先点火事件的方法包括进行气缸内测量并使用测量来确定作为功能曲柄的气缸（20）内释放的瞬时热量 角度。 如果在预期的火花正时之前释放出明显的热量，则在检测相同发动机循环中的早期放热（预点火）之后，最好在检测之后的45个曲柄角度内，立即将额外的燃料喷入气缸（20） 的预燃。 额外的燃料淬火在气缸（20）内释放的热量以防止预先点火事件。
