Abstract: So that an actuator drive which holds an actuator element for actuating, for example, a charge cycle valve of an internal combustion engine, in a limit position by a coil, can be switched at the correct time into the other limit position, the energization of the coil is switched off a certain time period before the time at which the actuator element is to be released from the limit position. Here, the time period is selected as a function of the supply voltage of the actuator drive and/or of the coil current during the holding in the limit position. It is also possible to adapt the time period.

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.

Abstract: A method for operating a piston-type internal-combustion engine having electromagnetic valve trains for actuating the cylinder valves, which respectively have an armature that can move back and forth between two electromagnets, counter to the force of restoring springs, with the valves being completely variably actuated by an electronic engine timing control unit. The functioning of the electromagnetic valve trains of each cylinder is detected in the engine timing control unit during operation, and when a functional failure of an electromagnetic valve train is detected at a cylinder, the electromagnet of the failed electromagnetic valve train is acted upon with a capturing current, which brings the armature into an end position at an electromagnet, and from this end position, the electromagnetic valve train is actuated for the ongoing work cycle of the cylinder.

Abstract: A method for controlling a valve lift device associated with an internal combustion engine includes determining, according to maps, a relative timing angle to be applied to a camshaft and crankshaft. The determined timing angle is processed with a PID-type control. Each time an engine enters a stabilized low idle speed, a reference value of the timing angle is determined when a valve lift device is inactivated. The reference value is taken into consideration when any later timing angle command is given. At least one further step is included. For example, a map of a duty cycle for an opening of a hydraulic valve controlled by the PID of the valve lift device is pre-established on a test bed as a function of an engine water temperature, and/or the timing angle to be applied as a function of the engine water temperature is adjusted by modifying the reference value.

Abstract: First and second valve-operating characteristic changing mechanisms for changing the valve lift and the valve timing of an intake valve respectively are provided on an intake side of an engine. A hydraulic pressure control valve for the first valve-operating characteristic changing mechanism is mounted on one side of a cylinder head, and an oil filter for the second valve-operating characteristic changing mechanism is mounted on the other side of the cylinder head. The hydraulic pressure control valve and the oil filter are mounted outside a chain cover covering a timing chain. Therefore, the control valve and the oil filter do not interfere with the timing chain, and the maintenance of the control valve and the oil filter is carried out without removal of the chain cover.

Abstract: An estimated value is calculated for a disturbing force which occurs as a result of the gas forces acting on the gas exchange valve immediately prior to the opening of the latter. The time profile of the disturbing force resulting at the gas exchange valve after the commencement of opening is estimated from a response of a transfer member to a jump in the disturbing force from the estimated valve to a predetermined value. An actuating signal for the actuator drive is determined as a function of the time profile of the disturbing force.

Abstract: A control unit controls both a motor actuated throttle valve and a magnetically actuated variable valve in accordance with an operation condition of an internal combustion engine. The control unit is configured to provide both a first control mode wherein an intake air control is carried out by controlling the open/close timing of the variable valve while keeping the throttle valve at a full-open or near full-open position and a second control mode wherein the intake air control is carried out by controlling the position of the throttle valve while reducing a controllable range of the open/close timing of the variable valve. The first and second control modes are selectively switched in accordance with the operation condition of the engine. The first and second control modes allow the engine to output the same engine torque under the same operation condition of the engine. The first and second control modes are respectively provided by calculating target intake air amounts for the first and second control modes and feeding the engine with the calculated target intake air amounts respectively.
