摘要： A fuel injection system includes a pressure booster having a displaceable piston which can be subjected to pressure via a pressure booster chamber on the low-pressure side for compressing the fuel in a pressure booster chamber on the high-pressure side to be delivered to an injector. The stroke of the piston is controllable by the pressure in a differential chamber of the pressure booster and is used to vary the fuel pressure delivered to the injector. Means for continuously variable definition of the inlet cross section to the pressure booster chamber of the pressure booster on the low-pressure side or of the outlet cross section from the differential chamber of the pressure booster are provided.

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： A pressure booster of a fuel injection system includes a displaceable piston unit (30a, 31a), which on one end can be subjected to pressure via a pressure booster chamber on the low-pressure side and on the other end has a pressure booster chamber on the high-pressure side for fuel compression. The piston unit has a further piston cross section, which is reduced compared to the first piston cross section provided for imposing pressure, for embodying a differential chamber that is connectable to a leak fuel line. At least one control conduit connects the pressure booster chamber on the low-pressure side to the differential chamber, whose opening is closed or opened as a function of the motion of at least parts of the piston unit.

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： A fuel injection system for internal combustion engines has at least one stroke-controlled injector. A pressure booster that has a movable piston is connected between the at least one injector and a high-pressure working medium source. The movable piston divides a primary chamber, which can be connected to the high-pressure working medium source, from a pressure chamber that communicates with the at least one injector and is filled with fuel. The pressure booster generates a first fuel system pressure in the injector, which is used for the injection. The fuel injection system has means for furnishing a further, second fuel system pressure, and these means can be used for injection without activating the pressure booster.
