    Abstract: An LED 103 and a photodiode 104 of a crank angle detector confront one another across a gap G', through which a plate 102 rotates. The LED and photodiode communicate through respective housing windows 111 when a slit 110 in the plate passes between them. The windows and the slit are sector-shaped, with concentric inner and outer edges, and radially oriented side edges. These configuration steepen the leading and trailing edges of the photodiode output, thus enhancing the detection accuracy.

    Abstract: An engine control apparatus and method for accurately controlling the operation of an engine such as ignition, fuel injection, etc., particularly in the high-speed range or during a sudden change in the rotational speed of the engine. A signal generator generates a positional signal in the form of pulses representative of a reference piston position of each cylinder in synchrony with the rotation of the engine. A sensor means senses the operating conditions of the engine. A control unit in the form of a microcomputer, which includes a timer means for controlling the operations of the corresponding cylinders, calculates, based on the positional signal and the output signal of the sensor means, control times for controlling the corresponding cylinders at every reference piston position, and determine, at every reference piston position, whether the timer means has already done control on the cylinders. If the timer means has yet to do control on the cylinders, the control unit resets or updates the dimer means to new control times which are calculated at the present reference piston position for controlling the present operations of the cylinders. On the other hand, if the timer means has already done control on the cylinders, the control unit sets the timer means to new control times which are calculated at the present reference piston position for controlling the next operations of the cylinders.

    Abstract: A cylinder recognition apparatus for a multi-cylinder internal combustion engine has a position sensor which generates for each cylinder output pulses which indicate prescribed positions of the piston of the cylinder. The output pulse for a prescribed reference cylinder of the engine has a different pulse width from the pulses for the other cylinders. A cylinder recognition circuit calculates a ratio which is a function of the pulse width and the period of each output pulse. A comparator compares the ratio with a prescribed value and a cylinder is recognized on the basis of the comparison.

    Abstract: In order to mount the control circuit for the ignition system at a location remote from the spark plug and ignition coil, i.e. at a location not subject to electromagnetic or electrical interference, photoconductors are used to interconnect the control circuit with the final output stage. Photoconductors are also used to interconnect the basic synchronization unit, that is the unit which furnishes a pulse for each rotation of a shaft of the engine, to the input of the control circuit. A theft prevention device is also incorporated. Specifically, the control circuit compares a sequence stored in a microprocessor to the on/off pattern of a received light pulse sequence. The latter is applied from a light emitter through a convex lens and a photoconductor to a second input of the control unit. Only if the stored pattern corresponds to the received light pattern can control signals initiating a spark be generated.
