摘要： The invention relates to a fuel pump for a fuel system of an internal combustion engine, having a housing and a housing cap joined to the housing. In order to create a fuel pump which in its operation generates little airborne sound, structure-borne sound (vibration amplitudes) and pulsations in a low-pressure region of the fuel pump, it is proposed that the housing cap has at least one damping element, which is embodied as a sandwich construction having at least a first cover layer, a second cover layer, and a damping connection layer disposed between them. The damping connection layer has a markedly higher elasticity and/or higher material damping than the two cover layers, which may be constructed of sheet metal or the housing cap itself.

摘要： A fuel injection system of an internal combustion engine delivers fuel into a fuel rail via a high-pressure pump. The quantity of the delivered fuel is influenced by a quantity control valve operated by an electromagnetic operating device. A trigger signal supplied to the electromagnetic operating device is defined by at least two parameters, and a) in an adaptation method with the second parameter defined, at least one first parameter of the trigger signal supplied to the electromagnetic operating device is varied successively up to a final value at which a closing or opening of the quantity control valve is at least indirectly no longer or just barely detected, b) the first parameter is subsequently defined at least temporarily based on the final value, and c) the temporarily defined first parameter is adapted based on at least one prevailing operating variable of the fuel injection system or the second parameter is adapted based on at least one prevailing operating variable of the fuel injection system and of the temporarily defined first parameter.

摘要： In a fuel injection system of an internal combustion engine fuel is delivered into a fuel rail by a high-pressure pump. The quantity of the delivered fuel is influenced by a quantity control valve operated by an electromagnetic operating device. At least one parameter of a braking pulse of the electromagnetic actuating device depends on an efficiency of the electromagnetic actuating device and/or on a supply voltage of a voltage source and/or on a temperature, in particular of a component of the fuel injection system or of the internal combustion engine.

摘要： In a fuel injection system of an internal combustion engine, fuel is delivered from a high-pressure pump into a fuel rail. The quantity of the delivered fuel is influenced by a quantity control valve which is activated by an electromagnetic actuating device. The level of control of the quantity control valve during the transition from the closed state to the open state of the quantity control valve is provided in the form of a sufficiently flat, descending progression which allows a robust control of the opening motion with regard to the varying specimen properties.
