Abstract
PURPOSE: To raise a rotational speed of the engine in a manner of good response, by making an interruption command of the fuel injection quantity, at the time of speed acceleration of the engine, to a microprocessor, for making an output as a digital signal on the basis of previously set information, with an arithmetic operation made immediately to provide the injection feed.
CONSTITUTION: A microprocessor 110, with the rotational speed information of a counter 112 and the intake air quantity information of an A/D converter 113 being the main information on the basis of the control program stored in a memory 111, makes an arithmetic operation of the fuel injection quantity synchronously with a rotational speed of the engine, providing an output as a digital signal with a corrective operation processed by a water temperature information from the A/D converter 113. Hereat, the fuel injection quantity is outputted as digital signal for showing a fuel injection time, that is, the valve opening time of an injection valve 8. A speed acceleration detecting circuit 116 detects a condition of rapid speed acceleration above the prescribed speed acceleration by the pulse signal from output terminals 5a, 5b outputting a speed acceleration signal for showing the condition of rapid speed acceleration.
