摘要： 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.

摘要： Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency or the engine.

摘要： Fuel management system for enhanced operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder. It is preferred that the direct injection occur after the inlet valve is closed. It is also preferred that stoichiometric operation with a three way catalyst be used to minimize emissions. In addition, it is also preferred that the anti-knock agents have a heat of vaporization per unit of combustion energy that is at least three times that of gasoline.
