摘要： An injection nozzle of a stroke-controlled fuel injection device has a control chamber for triggering a nozzle needle and also has a nozzle chamber connectable to a pressure booster. The communication between a differential chamber of the pressure booster and a leakage line and the communication between a control chamber and a leakage line are controllable with the aid of a common valve.

摘要： In a fuel injection system for an internal combustion engine, in which fuel at at least two differently high fuel pressures can be injected via injectors into the combustion chamber of the engine, parallel to a bypass line a hydraulic pressure booster is provided for generating the higher fuel pressure; the pressure booster is actuatable and deactuatable via a valve unit. Since the pressure booster is not constantly in operation, and the losses from friction are also reduced, the efficiency is improved.

摘要： In a fuel injection system for an internal combustion engine, in which the fuel pumped by means of a high-pressure pump can be injected into the combustion chamber of the engine at at least two different, high fuel pressure via injectors, between the high-pressure pump and the injectors, at least one central pressure booster unit for all the injectors is provided. The pressure booster unit is triggerable in a targeted way as need, and as a result the fuel which is at the higher pressure can be better regulated in quantity, and the losses from friction can be reduced accordingly as well.

摘要： A method for injecting fuel at at least two different high fuel pressures via injectors into the combustion chamber of an internal combustion engine. The fuel injection at the higher fuel pressure takes place by pressure-controlled features, during the fuel injection, at least one lower fuel pressure is generated. To that end, a fuel injection system has one local diversion unit for each injector, and the diversion unit can be activated or deactivated via a valve unit.

摘要： A fuel injection system includes a pressure storage chamber and one injector assigned to each cylinder, which injector can be connected to the pressure storage chamber via a pressure line that includes a metering valve. Using a single 2/2-way valve as a metering valve per cylinder makes for a more-economical manufacture of a fuel system, especially for small engines. The fuel injection is done under pressure control.

摘要： In a method for injecting fuel at at least two differently high fuel pressures via injectors into the combustion chamber of an internal combustion engine, the fuel injection at the lower fuel pressure takes place under stroke control, and the fuel injection at the higher fuel pressure takes place under pressure control. For a pre- and/or post-injection and/or a boot injection at the lower fuel pressure, the control chamber and via a check valve the nozzle chamber as well are connected to a low-pressure fuel supply, and that for a main injection at the higher fuel pressure, the nozzle chamber is connected to the high-pressure fuel supply.
