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 of operating a cylinder valve of an internal-combustion engine with an electromagnetic actuator for moving the cylinder valve into opposite open and closed valve end positions includes the steps of energizing an electromagnet of the actuator for generating an electromagnetic force for moving an armature of the actuator toward a pole face of the electromagnet against the force of a return spring; after the armature enters a zone adjacent the pole face of the electromagnet, applying to the armature an additional force opposing the electromagnetic force of the electromagnet; dimensioning the additional force such that an equilibrium between the electromagnetic force of the electromagnet and the increased opposing force of the return spring is situated at a location shortly before the armature enters into engagement with the pole face of the electromagnet; and after the armature reaches the location of force equilibrium, controlling a current supply to the electromagnet such that the armature reaches the pole face of the electromagnet with a predeterminable velocity.

摘要： A method of initiating motion of at least one of cylinder valve of a cylinder of a reciprocating engine, with each cylinder valve being actuated by an electromagnetic actuator having an electrical closing magnet and an electrical opening magnet, between which magnets an armature that is connected to the cylinder valve to be actuated is movably guided back and forth, counter to the forces of restoring springs, and with the alternating current supply to the closing magnet and the opening magnet being controlled by an electrical engine control. The natural frequency of the spring-mass system formed by the restoring springs and the armature with the cylinder valve is stored in the electrical engine control. The instantaneous rpm and position of the crankshaft with respect to a dead center point position and with reference to the stored natural frequency are detected by the engine control. The time for the beginning of an alternating current supply to the electromagnets is calculated in the period of the natural frequency, taking into consideration the crankshaft rpm and position, the natural frequency of the spring-mass system and the armature path from an inoperative position until it is in contact with the pole surface of one of the two electromagnets, so that the armature motion and the piston motion occur in the same direction immediately before a possible contact of the armature with the pole surface of a capturing magnet.

摘要： A device for the determination of the alcohol content and/or the calorific value of fuels by measuring the characteristics of the fuel in a measurement cell in which a flow body that is at least partially wetted by the fuel is arranged. The accuracy and speed of this measurement is improved by providing a first electrode for the dielectric measurement of the fuel and a second electrode for the measurement of the conductivity of the fuel on the outside of the flow body. Preferably the first electrode for the measurement of the capacitance, its outer connection and the walls of the measurement cell form a mechanically rigid system. It can also be expedient to mount the measuring circuit for the measurement of at least the capacitance directly on the housing of the measurement cell.

摘要： In a device for measuring and transmitting the combustion radiation in the combustion chamber of combustion engines, the combustion radiation in the movable part of the combustion engine is detected by means of optical sensors arranged therein and transmited through optical light guides to the fixed part of the engine. At the gap between the movable part and the fixed part an optical light guide emitting with its cross-section representative signals for the determined combustion radiation is arranged in the movable part, and on the fixed part opposite the gap an optical receiver is mounted for receiving and transmitting the received signals.

摘要： The present invention relates to a method for unthrottled load control of an internal combustion engine by means of exhaust gas. The method requires entirely freely adjustable opening and closing times for the inlet and exhaust valves. Starting at full load with the minimum of exhaust gas in the cylinder the amount of exhaust gas in the cylinder is increased thereby reducing the available combustion chamber volume for receiving fresh mixture mass thereby reducing the load. The fresh mixture mass and the exhaust gas mass are controlled exclusively by coordinating the opening and closing times of the intake and exhaust valves.
