Abstract
PURPOSE: To calculate an adequate fundamental pulse, by storing a pulse width correction value of the fuel injection fundamental pulse corresponding to the intake air amount of an engine and its speed and correcting a pulse width indexed from the measured intake air amount and speed of the engine.
CONSTITUTION: The intake air amount of an engine is measured by a thermal flow meter 10, and its output voltage is converted into a flow rate by a vlotage-flow converter 12. This flow rate value is input to a flow-speed correction circuit 14 to index a correction value of fundamental pulse from measured speed and flow rate value of the engine. The output of said correction circuit 14 is input to a fundamental pulse arithmetic unit 16, and to the output of said arithmetic unit 16 a correction unit 18 of various kinds is connected to perform the correction of fuel increase for the low temperature of cooling water. Output of the correction unit 18 is applied to a fuel injection output unit 20. The correction circuit 14, in case of the measured value in an intermediate value, calculates the fundamental pulse by supplemental calculation.
