Abstract: A fuel injection system has one or more unit fuel injectors or pump-line-nozzle units, corresponding in number to the cylinders, for compressing the fuel. The fuel injection system includes means for generating two different injection pressures during the injection and at least one valve for controlling the injection with a cross sectional control. The fuel injection with the aid of the unit fuel injector or a pump-line-nozzle unit can be achieved over a wide rpm range with great precision.

Abstract: In a pressure-controlled fuel injection system, a nozzle needle is subjected to pressure in the closing direction by a nozzle spring. A nozzle chamber for opening the nozzle needle is connectable to a pressure reservoir via a pressure line. A hydraulic device is embodied to reinforce the closing performance of the nozzle needle. As a result, a faster closing performance of the nozzle needle is achieved.

Abstract: In a fuel injection system for an internal combustion engine, in which fuel can be injected at at least two differently high fuel pressures via injectors into the combustion chamber of the engine, having a central distributor device for distributing the fuel to the individual injectors and having a central pressure reservoir for the lower fuel pressure, one valve unit for switchover between the two fuel pressures is provided locally for each injector individually. Furthermore, the central distributor device for the higher fuel pressure is disposed parallel to the central pressure reservoir for the lower fuel pressure. To enlarge the injection window for the pre-injection and the post-injection, the lower fuel pressure is metered from the central pressure reservoir, without going by way of the distributor device.

Abstract: A fuel injector in injection systems for internal combustion engines having a valve body containing a control chamber that can be pressure-relieved and can be acted on with fuel via an inlet throttle and can be pressure-relieved via an outlet throttle. A first actuator can actuate a closing element. The valve body is connected to a holding body that has a nozzle body connected to it, which encompasses an injection valve element. In order to relieve the pressure in the control chamber, an additional, second outlet throttle is provided, whose closing element can be actuated either by an additional actuator or as a function of the power supply to a double-switching actuator.

Abstract: A fuel injection system for internal combustion engines with a fuel injector that can be supplied from a high-pressure fuel source has an injection valve, with injection nozzles pointing toward the combustion chamber, and coaxial inner and outer nozzle needles assigned to the injection nozzles are triggerable as a function of pressure to open and close various injection cross sections at the injection nozzles. Each of the nozzle needless is assigned a respective damping piston, and the damping pistons are movable relative to one another and act on a damping chamber which can be made to communicate with a low-pressure return system via an outlet throttle. In addition to the damping chamber, a closing chamber is provided, to which an end face of the outer nozzle needle is exposed in the closing direction. The closing chamber can be made to communicate with the low-pressure return system as well, via a closing chamber throttle; the outlet throttle has a greater throttling action than the closing chamber throttle, so that the pressure in the closing chamber drops first, and only after a delay does the pressure in the damping chamber drop as well.

Abstract: A fuel injection is effected by means of a high-pressure pump (2) and a pressure reservoir chamber (6) for generating and storing a first system pressure. This system pressure is not used for injection; instead, by means of the pressure booster unit (9), a higher injection pressure is generated during the injection, and this injection pressure can be reduced to shape the course of injection. By means of this invention, an improved capability of metering the fuel injection and an improved execution of fast switching times are achieved.

Abstract: A pressure booster for increasing the injection pressure in direct-injection internal combustion engines with a plurality of cylinders, in particular diesel engines, having a booster piston which has a relatively large end face that is subjected to a relatively low pressure and a relatively small end face at which in the pumping stroke an elevated injection pressure prevails, wherein on the side remote from the relatively large end face, because of the difference in size between the two end faces of the booster piston, an idle volume results. The idle volume is in communication with a cantilevered spring reservoir disposed locally for each individual cylinder or centrally for all the cylinders of the engine.

Abstract: A method and system for injecting fuel in at least two different high fuel pressures via injectors into a combustion chamber of an internal combustion engine. The higher fuel pressure being stored in a central pressure reservoir, the lower fuel pressure is generated individually locally for each injector, at all times during the injection event by diversion of the higher fuel pressure. The diversion being activatable or deactivatable via a multi-way valve. To that end, a corresponding fuel injection system with a central pressure reservoir for storing the higher fuel pressure has a local diversion unit for each injector by means of which the lower fuel pressure can be generated dissipatively from the higher fuel pressure, and the local diversion unit has a multi-way valve for activating and deactivating the diversion, respectively. In this way, an improved metering of the lower fuel pressure can be achieved.
