摘要： Disclosed is a fuel injector for internal combustion engines, in which a cross section (21) of an outlet is unblocked to establish a connection between injection pumps (1) and an injection nozzle (2) at the beginning of the pressure reduction process introducing the end of the injection phase such that the compressed fuel volume can be discharged quickly, thus allowing the pressure to be reduced rapidly.

摘要： An internal combustion engine (1) for operation in a switchable manner with liquid fuel or gaseous fuel operates with pilot injection in the gas mode, wherein in the event that the injectors (5, 8) provided for the pilot injection in the gas mode and for the injection in liquid fuel mode are connected to a common accumulator (6), the pressure level thereof is lower for the pilot injection in the gas mode than for the operation with liquid fuel.

摘要： The invention relates to a fuel injection nozzle for internal combustion engines, in particular self-ignition-type internal combustion engines, comprises a nozzle needle (5) having a shank section (7) guided in a longitudinal bore (4) of the nozzle body (2), which shank section transitions into a constricted shank section (14) passing through a pressure chamber (9), wherein the transition between said shank sections is located within the longitudinal bore (4) spaced from the junction thereof into the pressure chamber (9).

摘要： The invention concerns a pressure limiting valve (1) for fuel injection devices, in particular for fuel injection devices produced in the form of supply manifold systems. The inventive pressure limiting valve comprises a housing (2) including a high pressure connection (5) on the intake side, a backflow connection (9), as well as a flow connection located between said two connections and controlled by a valve element (7) which is guided mobile in the housing (2) and which is sealingly spring-biased towards a valve seat (6) on the intake side in the direction of its locking position. Said valve element opens, while being limited by a stop, via a high pressure applied on the intake side and its surfaces pressurized to counter the spring force are larger in the opening position releasing the flow connection than in the locking position. Since the valve element (7) is coupled, in terms of displacement, to a surface (17) of a piston (12) mobile in the housing (2), said surface being capable of being pressurized to move the valve element (7) in the opening position, it is possible in certain operating conditions, in particular when the engine is stopped for maintenance, to open the valve regardless of the dimensioning of the pressure limiting valve so as to reduce to a selectable predefined level the pressure in the connected fuel device.
