20130024092 | DEVICE FOR PREVENTING THE ENGINE FROM STALLING IN A VEHICLE EQUIPPED WITH A DIESEL INJECTION SYSTEM - A device is provided for preventing the engine from stalling in a vehicle equipped with a diesel injection system, particularly a common-rail injection system. The device comprises a volume flow control valve, a high-pressure fuel pump, a pressure control valve, one or more injectors and a control unit. The control unit carries out a pressure control by controlling the volume pressure control valve in the idle state of the engine in a first operating mode, monitors whether a working point is present at which a release of air from the fuel is carried out and, in the event such a working point is detected, initiates a second operating mode in which a pressure control is carried out by controlling the pressure control valve. | 01-24-2013 |
20130291836 | Fuel Injection System Of An Internal Combustion Engine, And Associated Pressure Regulating Method - A fuel injection system of an internal combustion engine includes a first and a second fuel pump, a leakage-prone volume flow regulating valve arranged in a fuel line between the first and the second fuel pump, and a control unit configured to actuate the first fuel pump as a function of a position of the leakage-prone volume flow regulating valve, such that the leakage-prone volume flow regulating valve serves as the sole actuating element for pressure regulation in the fuel injection system. An associated pressure regulating method is also disclosed. | 11-07-2013 |
20140196691 | Method And Device For Controlling A Valve - A valve includes a spring having a spring force, an actuator having an actuator force that acts against the spring force, and a tappet that can be actuated by means of the actuator. The valve also includes a sealing element, which is or can be coupled to the tappet, and a sealing seat, such that the valve is closed when the sealing element lies against the sealing seat. A current having a specified curve, proceeding from an initial value of the current to a specified final value of the current, is applied during a specified time interval of the actuator after a closing phase of the valve for a normally open valve or after an opening phase for a normally closed valve. The initial value of the current is less than the final value. | 07-17-2014 |
