摘要： A reciprocating piston internal combustion engine includes: a sensor system on a gas exchange valve which has a valve head situated at a first end of a valve stem; a lever element which engages at a second end of the valve stem and which is designed to actuate the gas exchange valve by displacing the valve head; a detection element which, upon actuation of the gas exchange valve, is displaced along a displacement path; and a sensor device configured to ascertain a position of the detection element. The sensor device is situated in such a way that the detection element, during a displacement along a portion of the displacement path, moves predominantly in a movement toward the sensor device or away from the same, thereby providing a measurement of valve timing of the gas exchange valve.

摘要： A linear variable differential transformer (LVDT) for monitoring engine valve position is disclosed. The system includes a valve guide having an elongated recess through it. The engine valve has a valve head and a valve stem with two adjacent materials having different magnetic properties meeting at an interface. The valve stem fits and moves linearly within the valve guide, and the valve head closes an engine combustion chamber. It also includes monitoring coils within the valve guide that create a signal related to the position of the interface within the valve guide. An engine control unit (ECU) is coupled to the monitoring coils and receives and analyzes the signal from the monitoring coils to determine operation of the valve.

摘要： A system for preloading a latch used in a variable valve actuation system for internal combustion engines is disclosed. It includes a rocker arm assembly having a first arm for operatively engaging the first cam for a first desired lift profile, and a second arm for operatively engaging the second cam for a second desired lift profile. A selectively-activatable latch to operatively latch the second arm with the first arm. An electronic control unit (ECU) communicates with an oil control valve that changes oil pressure to the latch to cause it to secure the arms together, or allow them to move independently. Due to the short time period required to operate the latch, the ECU provides a signal for the oil control valve to supply oil pressure or release oil pressure prior to the rocker arms being engaged with the base circle of the cams. This effectively preloads the latch causing it to react quickly and within the small time period allowed to latch.

The method for controlling the actuator includes: a. Starting of a drive pulse having a setpoint duration of the drive pulse for opening and/or closing the valve, b. Generating at least one signal, and c. Correcting the setpoint duration of the drive pulse and/or of a following drive pulse assigned to the lift and/or to a partial lift, in accordance with the signal.

摘要： According to the invention, recuperation may be optimized for a hydraulically-operated gas exchange valve by provision of two fluid-filled pressure chambers and a movable regulating piston with two active faces each defining one of the pressure chambers. The pressure chambers are each connected to two hydraulic valves of which the first hydraulic valves may be pressurized from a first pressure reservoir and the second hydraulic valves may be connected to a base pressure reservoir. The first hydraulic valves may furthermore be connected to a second pressure reservoir. A control or regulation device switches the valves, from a rest position in a first accelerating phase and a braking phase. The second pressure reservoir is provided as pressure buffer for providing the pressure in the first pressure reservoir and/or for providing pressure for the fuel pump and/or for the fuel supply to an internal combustion engine and/or for providing pressure for a further gas exchange valve in the same or another combustion cylinder of the internal combustion engine.

摘要： A method for controlling stopping and starting of an engine having a variable event valvetrain is described. According to the method engine valves may be used to reduce engine evaporative emissions as well as engine starting emissions. Since the engine configuration shown has electrically actuated intake and exhaust valves it is possible to reconfigure the engine operating sequence during a start. For example, the pistons for cylinders two and three are in the same position at the same time. This allows either cylinder to be set to an intake stroke during a subsequent engine restart when the piston is traveling away from the cylinder head while the companion cylinder is set to the expansion or power stroke. Thus, the cylinder having the first intake stroke could be configured to provide a first combustion event during an engine restart. On the other hand, the cylinder set to the power stroke could have been set to the intake stroke such that it is the first cylinder to provide a combustion stroke during a restart.

摘要： A piston rod position detecting mechanism is proposed which can detect continuously or in a multiple-point manner that the piston rod position has changed due to increase or decrease in the protruding amount of the piston rod due to aging. The protruding amount from a cylinder end wall is detected by a position detecting mechanism comprising a detecting coil housed in a bobbin provided at the cylinder end, a flange portion formed on the piston rod, and a coil spring. Also, an autotensioner and an electromagnetic valve with such a position detector are proposed. Further, a belt tension adjusting device is provided with a detector for detecting the position of a tension pulley which is pivotable with increase or decrease in the belt tension.

摘要： A valve lift sensor detects the position of an engine valve. The valve lift sensor includes a movable target carried on an engine valve and a stationary coil carried within an engine valve assembly. A signal generator energizes the coil with an oscillating voltage to create an oscillating magnetic field, which is concentric to the coil for inductive transfer with the target. A comparator compares the voltage from the signal generator with the voltage at the resistor to determine the phase lag of resistor voltage relative to signal generator voltage and indicate the engine valve position. Using the phase lag, the comparator provides a pulse-width-modulated signal with a duty cycle proportional to the valve lift to an engine valve control operable to control the operation of the engine valve.
