    摘要: An arrangement for supplying current to the solenoid valves of an electrohydraulic valve-timing system of an internal combustion engine in a controllable manner has solenoid valves assigned to the gas-exchange actuators. A two-stage supplying of voltage is provided for the solenoid valves, namely the supplying of an inrush voltage from an inrush voltage source, and the supplying of a holding voltage from a holding voltage source. In this context, the inrush voltage is greater than the holding voltage. The solenoid valves can be actuated independently of one another for the duration of an inrush current time by an inrush current that corresponds to the applied inrush voltage, and for the duration of a holding current time by a holding current that corresponds to the applied holding voltage. For each solenoid valve, one holding voltage line and one inrush voltage line are provided, which connect the solenoid valve to the holding voltage source and to the inrush voltage source, respectively. From each solenoid valve, a ground lead leads to ground, a ground lead disconnector being provided in the ground lead for switchably disconnecting the electrical connection between the solenoid valve and ground.

    摘要: A device for monitoring at least two electromagnetic valves of an internal combustion engine in a motor vehicle. An actual current that is independent of the other valves may be supplied to each valve. A setpoint current is preselected for each valve. Measuring devices are provided for measuring the actual currents supplied to the valves. A control unit is used to add the measured actual currents to yield a total actual current. Due to the control unit, the setpoint currents are added to yield a total setpoint current and compared to the total actual current. This comparison is used by the control unit for monitoring the valves and/or their interconnections.

    摘要: A method for triggering solenoid valves assigned to gas-exchange valves in an electrohydraulic valve activation of an internal combustion engine having a plurality of combustion chambers. The solenoid valves assigned to the gas-exchange valves may be activated independently of each other. To this end, crankshaft-synchronous trigger signal for solenoid valves of the internal combustion engine are ascertained in a control unit and transmitted to an output stage. The output stage controls the solenoid valves on the basis of the transmitted trigger signals. Each combustion chamber of the internal combustion engine has at least one intake valve and at least one discharge valve as gas-exchange valve. All solenoid valves of all gas-exchange valves of a combustion chamber form a solenoid-valve set. One activation profile in each case is specified for all solenoid valves of a solenoid valve set. In the control unit, a crankshaft-synchronous activation signal is ascertained for each combustion chamber and supplied to the output stage. The output stage triggers the solenoid valves of the solenoid-valve set on the basis of the activation signal of the cylinders according to the activation profile stored for the individual solenoid valve.

    摘要: In an hydraulic actuator, a movement of an actuating element of the actuator is effected in that a working chamber of the actuator, with the aid of a valve device, is able to be selectively connected to, and disconnected from, a fluid reservoir in which pressurized hydraulic fluid is stored. The lift of the actuating element of the actuator is a function of a fluid volume present in the working chamber. It is provided that, to ascertain an instantaneous operating performance of the actuator, the working chamber is briefly connected to the fluid reservoir, the corresponding pressure drop in the fluid reservoir is recorded, and the corresponding lift is determined from the pressure drop with the aid of known geometrical variables of the actuator.
