摘要： When a pressure of fuel is intensified using a pressure intensifier an electronic control unit is configured to set a target common rail pressure to be higher as a fuel leakage volume that is a volume of fuel leaking from a common rail to a fuel tank becomes larger until a three-way valve is switched from a state in which the pressure intensifier is connected to the common rail to a state in which the pressure intensifier is connected to the fuel tank.

摘要： A fuel injector assembly has a control valve body and a plurality of end caps. End cap locating holes are formed into a mating surface of each end cap, and control valve body locating holes are formed into each mating surface of the control valve body. Locating pins inserted into the end cap and control valve body locating holes each have a fixed portion that affixes the locating pins to either the control valve body or the end cap. In the event of failure of a locating pin between the fixed portion and a free portion of the pins, the free portion maintains alignment of the control valve body locating holes with the end cap locating holes.

摘要： The present invention relates to a two-stage fuel injection valve. The two-stage fuel injection valve of the present invention is configured such that the pressure of main fuel delivered from an injection pump is applied to a plunger in a main fuel chamber, and subsequently delivered to an ancillary fuel pressure chamber via the plunger so as to compress ancillary fuel, such that a needle is retracted in a manner similar to those of slide valves by means of the pressure of the ancillary fuel so as to open an ancillary fuel nozzle hole and inject the ancillary fuel, and a main fuel nozzle hole is opened after the injection of the ancillary fuel so as to inject the main fuel, thereby conducting two-stage fuel injection.

摘要： Methods of operating fuel injectors with intensified fuel storage. At least one storage volume is provided in the intensifier type fuel injector, with a check valve between the intensifier and the needle chamber and storage volume preventing loss of injection pressure while the intensifier plunger cylinder is refilling with fuel. Using the check valve to isolate the storage volume from the intensifier to reduce and control pressure spikes that effect injector operation. This provides very efficient injector operation, particularly at low engine loads, by eliminating the wasted energy of compressing, venting and recompressing fuel for injection and reducing and controlling pressure spikes that effect injector operation.

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.

摘要： A pressure intensifier (64) is controlled by a control valve (ICV 66) to intensify pressure with which fuel is injected from an outlet port (40) of an injection device (20) into an engine cylinder in comparison to that at which fuel is introduced. A controller operates both a needle control valve (NCV 54) and the ICY valve during an engine cycle to cause: intensified pressure to be applied to fuel in the injector while the fuel outlet port is closed; then the outlet port to open while intensified pressure continues to be applied as fuel is injected; then while the outlet port remains open and fuel injection continues, the intensified pressure attenuates; then after the intensified pressure has attenuated, the outlet port is re-closed to terminate injection; and then the outlet port is re-opened and the attenuated pressure re-intensified to inject fuel at re-intensified pressure.

摘要： Digital fuel injector, injection and hydraulic valve actuation module and engine and high pressure pump methods and apparatus primarily for diesel engines. The digital fuel injectors have a plurality of intensifier actuation pistons allowing a selection of up to seven intensified fuel pressures. The disclosed engine operating methods include using at least one cylinder for a compression cylinder for providing compressed intake air to at least one combustion cylinder. A pressure sensor in each combustion cylinder may be used to indicate temperature in the combustion cylinder to limit combustion temperatures to below temperatures at which substantial NOX is generated. A re-burn cycle may be used to complete the burning of hydrocarbons, providing a very low emission engine. A compression cylinder may be provided with a pump actuated by the piston in the compression cylinder. Various aspects and embellishments of the invention are disclosed.
