Abstract
PURPOSE: To perform arithmetic operation of an injection pulse on the basis of suction air quantity more practical than a mean value, by determining the final read value in a turn of rotation as the suction air quantity when performed the decision of a transient state.
CONSTITUTION: A converter 23 reads a continuous flow meter output 1 in a certain period. Count of this read value is converted into voltage in a counter 24 further converted into an air quantity Q in a table look up 25. A next integrating unit 26 performs integration of the air quantity Q while in a crank angle of 360° simultaneously counts a read number of times N. At reception of a 360° signal a transient state decision device 27 performs decisions for a steady state, that is, almost at constant speed and a transient state, that is, acceleration or deceleration state. And if a transient signal (f1=1) is generated, the final air quantity value Q' read while in a turn of rotation is determined as a calculation value U, then the air quantity Q and count value N already integrated are reset.
