摘要: An apparatus and method for operating a plurality of valves in an engine uses valve actuators to move each valve. Accelerometers are used to detect acceleration of the valves and particularly the moment when they seat. A knock sensor detects an acoustic impulse made by the valves when they seat. A controller correlates signals from the sensor and accelerometers, wherein a signal from the sensor that correlates in time with a signal from an accelerometer indicates seating of the respective valve, which indicates a closure of the respective valve. The controller measures a magnitude of the acoustic impulse to be used as feedback in controlling the operation of the respective valve actuator, and provide softer landings of the valve.
