摘要： A fuel injector has a seat and at least one seat passage. The seat includes an outer tip surface through which the seat passage extends. Fin structure is provided in the outer tip surface and is constructed and arranged to increase a surface area of the outer tip surface as compared to a surface area of the outer tip surface absent the fin structure. The outer tip surface, including the fin structure, is constructed and arranged to be heated by combustion gases so that the outer tip surface reaches a temperature greater than a temperature that the outer tip surface would reach absent the fin structure, so as to cause evaporation of fuel that contacts the outer tip surface.

摘要： A heat transfer system for use in an internal combustion engine and related methods are disclosed. The heat transfer system may be configured to absorb and transfer heat from a combustion chamber of an internal combustion engine. The heat transfer system may also be configured to reintroduce absorbed and/or transferred heat into the internal combustion engine via a fuel injector or another suitable device. Removal of the heat from the combustion chamber may reduce a quantity of work required or used for compression of a first combustion fluid, increase a charge density in the combustion chamber, and/or increase the compression ratio of the engine. Additionally, the heat transfer system may be designed such that it may be used to retrofit an existing internal combustion engine.

摘要： In a method for injecting fuel into the combustion chamber of an internal combustion engine, the fuel is fed by at least one prefeed pump from a tank to at least one high-pressure pump and the high-pressure fuel fed by the high-pressure pump is supplied to the injector, wherein the injector has an injection nozzle with an axially movable nozzle needle protruding into a control chamber which can be fed with fuel under pressure and whose pressure is controlled by a control valve which opens or closes at least one inflow or outflow duct for fuel. Between the prefeed pump and the high-pressure pump, a partial volume of the fuel is branched off as a flushing volume and supplied to a flushing channel of the injector, wherein the flushing volume is directly supplied to the control valve such that the flushing volume flows at least partially through the control valve and preferably mixes with the fuel from the inflow or outflow duct, respectively.
