Abstract

PURPOSE: To increase accelerating power of an engine and prevent its temporary operation of power down or misfiring when an increasing rate of opening in a throttle valve exceeds an expected value, by injecting temporarily additional fuel for compensation to a standard amount of fuel injection.
CONSTITUTION: In a memory 1, engine speed Ne, throttle opening degree Qth and suction pressure PB are stored, and a standard fuel signal Ti is stored in accordance with the Ne and the other one of the values. The signal Ti read in accordance with the Ne and Qth or PB controls an injection nozzle through a preset down counter 6 and flip-flop. An increasing rate is obtained from values before and behind the Qth and compared with the three standard values in a comparator 17, then for not less than a prescribed value temporary fuel increase correction signal output is set in accordance with said increasing rate in a preset down counter 21 to perform the addition to the Ti through an OR gate 10.
