摘要： In a method and a circuit system for operating a solenoid valve, particularly for actuating an electrohydraulic gas-exchange valve control, an injection valve, or an intake or exhaust valve of an internal combustion engine, to permit the simplest possible driving of the solenoid valve, the solenoid valve is acted upon in a controlled manner in a cycle including three phases, in which in a pull-up phase, the solenoid valve is connected for a predefined time duration to a first voltage of predetermined magnitude for generating a pull-up current, in a holding phase is connected to a second voltage of predetermined magnitude for generating a holding current, and in a de-energize phase is separated from both voltages.

摘要： The valve has a valve shutter cooperating with an actuator housed in an actuator chamber (10), and a valve seat housed in a control chamber (11). A sealing unit (19) is provided between frontal surfaces (21, 22) of respective shutter segments (3.1, 3.2) of the shutter and tightly separates the chamber (11) from the chamber (10). The segment (3.2) slides transversally to a valve axis (25) in a pressure reduction channel (39).

摘要： Described is an apparatus for rapid pressure buildup in a motor vehicle reservoir-type injection system (common rail) supplied with fuel by a high-pressure pump, the apparatus including a piston, which defines a pressure chamber that can be enlarged counter to the force of a spring element prestressed counter to the piston, which pressure chamber communicates with the feed pump and with the device supplied with the pressure medium. A locking device acting on the piston is provided, by which the piston can be locked in a locking position, assumed as a result of the pressure, built up in the pressure chamber by the feed pump, counter to the prestressing of the spring element and can be untensed after unlocking into a position that reduces the size of the pressure chamber. By the relaxation of the spring, the system pressure is built up suddenly.

摘要： A device for controlling a gas exchange valve for internal combustion engines, having a housing including an axially movable valve member, which on an end close to the combustion chamber, has a valve sealing face that cooperates with a valve seat affixed to the housing and on an end remote from the combustion chamber, has a piston that axially separates upper and lower hydraulic working chambers from each other. The lower working chamber closer to the combustion chamber acts on the valve member in the closing direction and the upper working chamber further from the combustion chamber acts on the valve member in the opening direction. The lower working chamber continuously communicates with a high pressure source and the upper working chamber can be alternatingly filled with high pressure by way of a high pressure supply line containing an electric control valve. The upper working chamber is discharged by way of a discharge line that contains an electric control valve. When the electric control valve is without current, the control valve closes the high pressure supply line connected with the upper working chamber and when the electric valve in the discharge line is without current, the discharge line is open.

摘要： A method for cylinder-charge control is described as implementing an internal recirculation of residual gas in the cylinder, through controlling the closing times of at least one exhaust valve of the respective cylinder and by opening at least one intake valve in the vicinity of top dead center of the piston, along with intermittent discharge of residual gas in front of the at least one intake valve. Within one charge-exchange process in the cylinder, in at least two phases that are offset in time from one another, at least one intake valve is opened. This method optimizes the engine operation in the warm-up phase from the standpoint of consumption, pollutant emission and running smoothness.

摘要： The invention relates to an electrohydraulic valve control system (10) of an internal combustion engine, comprising at least one actuator (24) which acts on a gas exchange valve (38). Said actuator, in turn, comprises at least one working chamber (30) which is connected to a high-pressure hydraulic accumulator (16) for actuating the actuator (24) in such a way that it moves from a first position to a second position, and which is separated from a low-pressure return line (56). In order to actuate the actuator (24) in such a way that it moves back from the second position into the first position, the working chamber (30) is connected to the low-pressure return line (56) and is separated from the high-pressure hydraulic accumulator (16). In order to easily maintain the pressure constant or to cause a pressure drop in the high-pressure hydraulic accumulator (16), the working chamber (30) is simultaneously connected to the high-pressure hydraulic accumulator (16) and to the low-pressure return line (56).
