摘要： A method for recognizing misfires in a piston-type internal-combustion engine with spark ignition and an engine control unit (ECU) for actuating electromagnetic actuators to operate the cylinder valves. The time difference between the opening time preset by the engine control unit and the actual opening time of an exhaust valve is detected as the actual value, then compared to a preset tolerance-time difference as the nominal value, and a signal is generated if this nominal value is not met, i.e., the nominal value exceeds the actual value.

摘要： A piston internal combustion engine with at least one gas exhaust valve (2) for each cylinder (1), which is actuated by an actuator (7), in particular an electromagnetic actuator, controlled by a fully variable engine control unit (15). Based on the predetermined operating cycle, the valve can close off the cylinder interior space against a gas exhaust channel (13) that follows the valve seat (3) of the exhaust valve. This channel is connected to an exhaust gas system and is provided with a means for example a constriction (14) for reducing the pressure gradient during the start of the opening of the gas exhaust valve (2). A specific pressure fluctuation is used for a further reduction in the pressure gradient behind the exhaust valves during the opening through a corresponding layout of the pipe geometry and the container volumes in the exhaust gas system or corresponding installed components.

摘要： A method for controlling an electromagnetic actuator for a cylinder valve in a piston-type internal combustion engine with the actuator being operatively connected to the cylinder valve and moveable back and forth between two electromagnetics, counter to the force of at least one restoring spring. The current supplied to the electromagnetics is controlled with the aid of a sensor arrangement and via an engine control unit such that the current supply to the catching electromagnet, i.e., the electromagnet being approached by the moveable armature of the actuator, is controlled so as to move the armature slowly toward the respective pole face. Moreover, in order to regulate the valve play during the closing movement of a cylinder valve, the current supply to the catching electromagnet is controlled such that the valve initially touches down softly on its seat and that following the valve play, the armature touches down softly on the pole face.

摘要： A method of controlling a supply current applied to an electromagnet of an electromagnetic actuator by a control unit for obtaining a low impact speed of a reciprocating armature of the actuator upon arrival of the armature at a pole face of the electromagnet, includes the following steps: during travel of the armature toward the pole face detecting displacements of the armature and a sequence of the armature speed as actual values; comparing the actual values with a performance characteristic field stored in the control unit and relating to a predetermined relationship between armature speed and armature displacement for the armature travel toward the pole face; determining a desired value for the supply current from the comparison step; comparing an actual value for the supply current with the determined desired value; adjusting the supply current based on a difference between the actual and desired values; and applying the adjusted supply current to the electromagnet.

摘要： A method for monitoring the operation of a piston-type internal combustion engine, comprising electromagnetic actuators with filly variable actuation for the cylinder valves, wherein the engine control unit supplies current based on respective predetermined current flows. The actuators are associated with respective sensors for detecting operation and transmitting operationally relevant signals to the engine control unit of the displacement movement of the respective actuator. The engine control unit detects the current and voltage flows for the actuator and, if no sensor signal is received, a sensor failure or actuator failure is detected from the voltage flow at the actuator. If a sensor fails at the actuator, the detection of a sensor signal is taken from a different, corresponding actuator by the engine control unit and the engine control unit causes initiation of a starting operation (start of oscillations) for the actuator initially determined to be non-operative. If an actuator failure subsequently is detected, the associated cylinder is shut down.

摘要： A method for starting up an electromagnetic actuator operating an engine cylinder valve. The actuator has two spaced electromagnets, between which an armature, connected to the cylinder valve, is reciprocated against a restoring spring from a center position to lie against a magnet pole face. An ECU alternatingly supplies the electromagnets with a capturing current, the level of which is regulated as a function of the approach of the armature toward a pole face, as detected by a sensor assembly. A reference temperature is detected for the magnets, and, at a normal temperature, the armature starts oscillating due to the alternating energization of the electromagnets, and is brought into contact with a pole face. Or, at a low temperature level, one of the electromagnets is supplied with a high current pulse.
