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.

摘要： A lean-burn engine may comprise a combustion chamber, an intake manifold configured to provide a lean fuel/air mixture to the combustion chamber, and a pre-chamber in fluid communication with the combustion chamber. The pre-chamber may include a spark igniter configured to initiate combustion of the lean fuel/air mixture in the combustion chamber, and a heating element contained in the pre-chamber. The heating element may be configured to heat the pre-chamber to a temperature sufficient to allow the production of hydrogen peroxide (H2O2) from fuel and air in the pre-chamber.

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： The internal combustion engine has an upstream side NOX selective reduction catalyst and a downstream side NOX selective reduction catalyst which are arranged in an engine exhaust passage. The upstream side NOX selective reduction catalyst has a region where the NOX removal rate becomes substantially constant when the ratio of concentration of ammonia to NOX of the inflowing exhaust rises. The internal combustion engine has an operating state in that region where the ratio of concentration of ammonia to NOX is maintained. The downstream side NOX selective reduction catalyst has an ammonia oxidation ability which is larger than the upstream side NOX selective reduction catalyst.

摘要： A system and method for preventing knocking prevents knocking by injecting a sub fuel including ethanol having high octane number to a combustion chamber in a case that the knocking occurs. The system for preventing knocking may include a cylinder, a piston moving in the cylinder reciprocally, forming a combustion chamber with the cylinder, and having a central axis, a first injector mounted at an upper surface of the cylinder with a distance from the central axis of the piston, and directly injecting a main fuel including gasoline into the combustion chamber, a second injector mounted at the upper surface of the cylinder on the central axis of the piston, and directly injecting a sub fuel including ethanol into the combustion chamber, and a spark plug disposed at the upper surface of the cylinder near the second injector.
