ABSTRACT:
Small change in the period of a crank-angle signal which is generated at every crankshaft rotation of a predetermined angle is not faithfully reflected to a false crank-angle signal which is used by a fuel injection control device for detecting the engine's running speed. Thus, even when the actual running speed is varied, the running speed recognized by the fuel injection control device doesn't change faithfully to this variation. Therefore, the amount of fuel injected into the engine, which amount is calculated in accordance with the running speed, doesn't vibrate with the variation of the running speed, preventing the surge phenomenon from occurring.
