摘要： The invention relates to an engine having prechamber ignition, in particular a gas engine, that comprises a main combustion space in a cylinder of the engine for combusting an air-fuel mixture and a prechamber having an ignition device arranged therein and a fuel injector arranged therein, wherein the prechamber has at least one transfer port that fluidically connects the prechamber to the main combustion space. The engine is characterized in that the fuel injector arranged in the prechamber is the only fuel injector via which fuel can be introduced into the associated main combustion space.

摘要： The invention relates to an axial piston machine comprising a swash plate, a drive shaft having a driving mechanism, one or more driving mechanism pivots that are displaceable therein and whose piston stroke can be set by the swash plate, a mechanical adjustment unit for changing the pivot angle of the swash plate, and an externally controllable control valve. The control valve has a valve housing having a control displaceable control piston, with the adjustment device being hydraulically actuable by means of the control valve. An adjustment chamber of the control valve is connectable in dependence on the switched state of the control valve to a high pressure inlet or to a low pressure inlet for the hydraulic pressurization of the adjustment device via a setting pressure connection radially extending through the control piston. A connection between a high pressure inlet and a setting pressure connection can be selectively established in regular operation via a first control edge or between the low pressure inlet and the setting pressure connection via a second control edge. In a first aspect in accordance with the invention, a connection can be established between the low pressure inlet or high pressure inlet via a further control edge in emergency operation without an active control. In a second aspect in accordance with the invention, a control pressure inlet of the control valve is connectable to a hydraulic tank or to a hydraulic source via an integrated or attached valve. The invention further relates to a control valve for an axial piston machine in accordance with the first aspect.

摘要： The invention relates to a system for supplying a gaseous fuel that comprises a low temperature tank for receiving the fuel in its liquid aggregate state achieved by cooling and comprises a rail that is fluidically connected to at least one injector device for discharging gaseous fuel into a combustion space. The system is characterized in that it has a pressure store that is configured to receive gaseous fuel and that is fluidically connectable to both the low temperature tank and the rail to buffer fuel coming from the low temperature tank and to supply it to the rail.

摘要： The invention relates to a device for supplying a gaseous fuel to an engine that comprises a gas accumulator for receiving highly pressurized gaseous fuel, a gas buffer for receiving medium pressurized gaseous fuel, a gas supply device for delivering a gaseous fuel into an engine combustion space, a first gas line that connects the gas accumulator to the gas buffer and whose gas flow can be regulated via a first valve, a second gas line that connects the gas accumulator to the gas buffer and whose gas flow can be regulated via a second valve, and a third gas line that connects the gas buffer to the gas supply device. The device is further characterized in that a compressor is arranged in the second gas line to increase a pressure of a gaseous fuel flowing from the gas accumulator to the gas buffer.

摘要： A controller for a common-rail injection system includes a plurality of fuel injectors, a common fuel supply line for the fuel injectors, a high-pressure pump for supplying the common fuel supply line with fuel, and a pressure sensor for determining the pressure in the common fuel supply line. A determination unit evaluates data of the pressure sensor and, from the pressure drop caused by an injection in the common fuel supply line, determines the fuel quantity actually injected during this injection or a value derived therefrom. An adaption unit uses the results of the determination unit in order to adapt the actuation of the fuel injectors. The determination unit carries out at least one test injection, and the actually injected fuel quantity or a value derived therefrom is effected by way of the test injection or injections.
