    摘要： A rotational position detecting apparatus for use in spark ignition control systems for internal combustion engines. A plurality of angular informations are provided circularly on a rotatable disk except at the predetermined reference angular position of said rotatable disk. Two of the angular informations provided beside the reference angular position are spaced twice as wide as a predetermined angular interval between other two of the angular informations. A first and second signal generators spaced integer times as wide as the predetermined angular interval from each other are associated with the rotatable disk for generating respective a.c. output signals in response to the passing of each of said angular informations. The a.c. output signals of the first and second signal generators are applied to an electric circuit which subtracts one of the a.c. output signals from the other of the a.c. output signals and shapes the subtraction resultant signal into a pulse signal.

    摘要： A crankshaft rotational reference position detecting apparatus is adapted for use with ignition timing control systems for internal combustion engines. The apparatus comprises a rotor disk fixedly mounted on the crankshaft of an engine and having rotational angle information indicating slits and a rotational reference position indicating mark which are formed along the periphery thereof, a first sensor for detecting each rotational angle information indicating slit and generating a first pulse signal corresponding thereto, the first sensor producing no first pulse signal when a rotational reference position is detected, a second sensor located at a position displaced from the first sensor in a desired rotational direction and adapted to generate a second pulse signal delayed in phase from the first pulse signal, a storage device responsive to the second pulse signals to store the output level of the first sensor, and a detection circuit responsive to a change in the output of the storage device which is indicative of the detection of the rotational reference position by the first sensor so as to generate a reference position detection pulse. In the event that the rotor disk is rotated in the reverse direction, the detection of the rotational reference position does not result in the generation of any reference position detection pulse.

    摘要： In a method and apparatus for controlling a combustion engine, a digital computer repetitively and sequentially calculates first and second values corresponding to the proper settings or actuation of first and second control devices that are used to control the combustion of the air-fuel mixture, by sensing changes in the operating conditions of the engine, the computer being programmed to calculate such first and second values from a first fuction describing a desired relationship between the condition of the engine and the setting of the first control device and from a second function describing another desired relationship between the condition of the engine and the setting of the second control device. An interrupt controller is provided to receive pulses which are synchronized with the rotational speed of the engine (hereinafter: synchronized pulse or pulses) and at least one clock pulse in a predetermined time interval so as to initially calculate the first value in the computer upon receiving a synchronized pulse even during the calculation of the second value, and subsequently calculate the second value after completion of the calculation of the first value.
