摘要： A rotary actuator for imparting a rotational force to a rotary valve member of a multi-way valve device has a cylindrical housing and an electric motor housed therein and being operative to produce a torque corresponding to the input current supplied to the motor. The motor shaft is hollow and rotatably journalled by the end walls of the motor housing. A torsion bar is housed in the shaft and fixed at one end to one end of the shaft. The other end of the torsion bar is fixed to the housing so that, when rotational force is imparted by the motor to the shaft and thus the rotary valve member connected thereto, the torsion bar produces a return force applied to the shaft. The angular position of the other end of the torsion bar about the axis thereof is adjustable within a limited range. The actuator is suited to impart a rotational motion of less than 180.degree. and provides a reduced hysteresis in the rotation characteristics.

摘要： The timing of spark ignition is set in normal operating conditions at a programed spark advance angle corresponding to the MBT (minimum spark advance for best torque). When knocking of the engine is detected by a vibration sensor, the ignition timing is delayed by a predetermined amount, e.g., 2.DELTA..theta., for each engine cycle that knocking is detected in synchronism with the rotation of the engine. When knocking is not detected, the ignition timing is advanced by another predetermined amount, for each engine cycle that knocking is not detected. e.g., .DELTA..theta.. In this method for controlling the spark timing, the amount of retardation, 2.DELTA..theta., is selected to be larger than the other amount of advance, .DELTA..theta..

摘要： A spark-ignition timing of the internal combustion engine is normally set at an MBT (minimum spark advance for best torque). However, when a knocking of the engine is detected by a vibration sensor fixed to the engine, the ignition timing is retarded with respect to the MBT by an angle corresponding to either a non-knocking limit retard angle or a maximum retard angle determined by engine operating conditions whichever is smaller.

摘要： A method of detecting knocking intensity of an internal combustion engine uses a detector for detecting vibration propagated within the engine and a first calculation circuit for obtaining an average value of vibration sensed by the vibration detector within a predetermined crank angle before the top dead center, and in which knocking is identified when the ratio between the above average value and the maximum value of vibration after the top dead center exceeds a predetermined value. This method also uses a second calculation circuit for obtaining a further average value of vibration detected by the vibration detector within a predetermined crank angle after the top dead center of the internal combustion engine, and a knocking discrimination circuit for generating a knocking indication output corresponding to the ratio between the average value of vibration before the top dead center obtained by said first calculation circuit and the average value of vibration after the top dead center by said second calculation circuit.
