    摘要: An ignition system for internal combustion engines includes a monitoring circuit (9) which is used for introducing appropriate emergency measures for protecting the catalyst in the case of faulty ignitions. The ignition system includes an evaluation device (10), which subjects the ignition-diagnostic signal (Zund OK) to statistical weighting and, when the weighted ignition-diagnostic value (ZUNTAB) exceeds a specified threshold, introduces appropriate measures, the evaluation being continued steadily so that if the value subsequently falls below the fault threshold (AFSDZU), correction is recognized and the emergency measures are withdrawn.

    摘要: An hydraulic valve actuator for actuating a gas-exchange valve in a combustion cylinder of an internal combustion engine has an operating piston delimiting two pressure chambers, of which the lower pressure chamber acting in the valve-closing direction is permanently charged with fluid pressure via which an intake and return line can be charged by, or relieved of, fluid pressure. To brake the gas-exchange valve in the final phase of the closing procedure to reduce the set-down speed, the return line of the upper pressure chamber is split between two discharge openings, which are connected to one another and arranged in the housing with axial clearance, the upper discharge opening being coupled to a restrictor and the lower discharge opening being displaceable relative to the operating piston and disposed in its displacement path such that it may be closed thereby at a defined distance, prior to reaching its upper limit position.

    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: An hydraulically controlled actuator for activating a valve, especially for activating a gas-exchange valve in a combustion cylinder of an internal combustion engine, which includes two fluid-filled pressure chambers having controllable chamber volumes and a movable operating piston which delimits the pressure chambers by piston sides facing away from one another, the operating piston acting upon the valve and having an effective closing area acted upon by fluid pressure in the pressure chambers to close the valve and an effective opening area acted upon by the fluid pressure to open the valve. To influence the kinematics of the opening and closing movement of the valve, the operating piston is such that the surface area of at least one of the two effective areas changes along the sliding path of the operating piston.
