Abstract: In an electromagnetically powered engine valve control apparatus of an internal combustion engine having an electromagnetic actuator which drives the engine valve electromagnetically, and a valve-lift sensor which detecting a valve lift of the engine valve, a control unit operates the engine valve in a selected one of a normal operating mode enabling both powered opening and powered closing of the engine valve by energization of the electromagnetic actuator, and a free-fly operating mode enabling a kinetic system of the engine valve to be free to fly according to a damped vibration system by deenergization of the electromagnetic actuator. The control unit calculates a damping coefficient as a ratio of a valve lift detected during the free-fly operating mode to a valve lift detected during the normal operating mode, and also calculates a desired valve open period from a time when the engine valve starts to open to a time when the engine valve closes, based on engine speed and engine load. A controlled current value of exciting current applied to the electromagnetic actuator is determined based on the damping coefficient and the desired valve open period.

Abstract: Die Erfindung betrifft ein Verfahren zur Nockenwellenverstellung in einer Brennkraftmaschine, wobei die Nockenwelle bzgl. einer Kurbelwelle mittels eines von einem Regler und einem Proportionalventil betätigten Verstellers um einen vorbestimmten Winkel verschwenkt wird, wobei der Regler einen Winkelsollwert mit einem Winkelistwert vergleicht, in Abhängigkeit von diesem Vergleich eine Stellgröße in Form eines Tastverhältnisses für das Proportionalventil bestimmt und bei Übereinstimmung von Winkelsoll- und Winkelistwert diese Stellgröße auf ein Haltetastverhältnis derart einstellt, daß der Winkelsollwert gehalten wird. Hierbei wird während einer Verstellung der Nockenwelle vor einem jeweiligen Soll-/Istwertvergleich dem Winkelistwert ein Prädiktionswinkel derart hinzuaddiert, daß die Summe aus Winkelistwert und Prädiktionswinkel einem Winkel der Nockenwelle entspricht, den diese nach Umstellen der Stellgröße auf den Haltewert bis zum vollständigen Schließen des Proportionalventils während einer Ventilschließzeit erreicht.

Abstract: The invention relates to an electronic device for controlling gas exchange valves in an internal combustion engine with variable valve timing, which makes it possible to fully close at least the intake valves and which is fitted with means for detecting the amount of air suctioned by the internal combustion engine and means for detecting valve lift. The electronic control device changes the opening function during displacement starting from a totally closed position of the intake valve in order to open the inlet valve, detect the extent to which the valve has being opened, whereupon the amount of air is detected and uses said extent as reference for determining the actual cross section of the aperture.

Abstract: In an internal combustion engine equipped with a pair of intake ports for each cylinder and capable of controlling a quantity of air entering the engine by controlling an intake valve open timing and an intake valve closure timing of each of a pair of intake valves located in the respective intake ports, a two-intake-valve operating mode is used in a high-load, high-speed operating range, whereas a one-intake-valve operating mode is used in predetermined low- and mid-load, low- and mid-speed operating ranges to create a great gas flow within the cylinder. A fuel injector is located in a first one of the intake ports to allow air flow through the first intake port over all operating ranges. An electronic engine control unit switches a compensating mode for an injection amount of fuel injected by the injector, based on changes in a quantity of wall fuel mass flow adhered onto the inner wall surface of the intake port during transient operating conditions, from one of a first compensating mode which is preprogrammed to be suitable for the one-intake-valve operating mode and a second compensating mode which is preprogrammed to be suitable for the two-intake-valve operating mode to the other.
