Abstract: A fuel injection system having a common rail pressure reservoir filled with high-pressure fuel and having a dual-fuel injector for a bi-fluid injection of fuel and an additive fluid into an internal combustion engine. The system includes a first 2/2-way valve in the injection line between the common rail pressure reservoir and a pressure chamber encompassing the injector needle of the dual-fuel injector as well as a second 2/2-way valve, whose inlet is connected via a supply line to the injection line at a point between the first 2/2-way valve and the pressure chamber, and whose outlet is connected to the low-pressure fuel side by way of an outlet line. As a result, the otherwise conventional 3/2-way solenoid control valves, which are significantly more complex technically, can be replaced by more reasonably priced 2/2-way valves. At the same time, this raises the possibility of shifting the quantity metering for additive fluid to a single metering valve that serves an entire group of injectors.

Abstract: A fuel injection device for an internal combustion engine having a fuel injection valve which sprays the fuel in the direction of an inlet valve and includes an electric heating element for the fuel before it reaches an inlet valve. The fuel injection device has a fuel injection valve which sprays the fuel in the form of a fuel jet in the direction of the inlet valve of the internal combustion engine, the fuel jet leaving the fuel injection valve at least in part strikes an electric heating element which, according to the invention, is designed as a Peltier element. The fuel injection device according to the invention is intended, in particular, for mixture-compressing, applied-ignition internal combustion engines.

Abstract: A fuel injection device for internal combustion engines is proposed in which a fuel injection valve is controlled by the pressure in a pressure chamber, which acts on a pressure shoulder in its opening and closing direction. The pressure supply to the a pressure chamber is controlled by a control valve member which in turn is moved by a pressure in a working chamber. The pressure in the working chamber is controlled by a pre-control valve which has a closing body which, through the influence of the piezoelectric drive mechanism, is moved from a second valve seat to a first valve seat and thereby momentarily opens a relief line of the working chamber. This movement results in an opening of the control valve member and a supplying of high fuel pressure to the pressure chamber for purposes of injection. Thus a very small pre-injection quantity is produced.

According to the invention, it is proposed that a plurality of flat bags be introduced into the cartons simultaneously, with the flat bags each being assigned to certain cartons.

Abstract: Known tank systems have an adsorption filter in order to accept degassing constituents of the fuel in a fuel tank. Such tank systems have to be tested for leaks and a pump appliance is provided for this purpose. The pump appliance is fitted to a ventilation conduit of the adsorption filter in order to supply a defined volume to the tank system so that an increase in pressure in the tank system is effected. In order to determine whether the tank system is pressure-tight, ample time is left after the pressure build-up in order that, if pressure decays, the conclusion can be drawn that there is a leak. The pump appliance according to the invention possesses an electromagnetic valve which has a vacuum connection connected to an induction pipe of an internal combustion engine in order to adjust, alternately, vacuum and ambient pressure in a pump space so that the pressure forces move a pump diaphragm in order to pump air into a ventilation conduit of an adsorption filter.

Abstract: The invention relates to a hydraulic brake system having a tandem master cylinder as the brake force set-point value transducer for braking by external force, downstream of which are disconnection valves for hydraulically disconnecting the master cylinder from wheel brake cylinders for external force braking. To achieve a pedal travel when the disconnection valves are closed, the invention proposes a lengthened idle travel of the pistons of the master cylinder, for instance by increasing a valve opening stroke of central valves integrated with the pistons. A travel-dependent pedal force is realized with simulator spring elements that act upon the pistons.

Abstract: The invention relates to a vehicle hydraulic brake system having a traction control unit and a dynamic driving control unit. To enable building up pressure quickly with a return feed pump, even when the master cylinder is not actuated, a precharge pump, which is mounted on the storage container of the master cylinder and can be made to communicate with the master cylinder through a valve that is mounted in the storage container following the master cylinder. When the master cylinder is not actuated, pressure can be built up in the master cylinder and thus in the vehicle brake system using the precharge pump.

The apparatus and the method are intended for an internal combustion engine of a vehicle.

Abstract: A fastening screw is used to hold a hollow body against a base body. To assure that no dirt can get into the hollow body, sealing between the fastening screw and the hollow body is necessary. The fastening screw has a bevel (10s) coated with a relatively soft coating at the transition between the screw shaft and the screw head. When the fastening screw is tightened, one edge of the hollow body digs into the coating, thus assuring a secure seal. The fastening screw is intended in particular in a brake system for securing a motor housing to a pump housing.
