Abstract
PURPOSE: To cut off a feed of fuel on the basis of output, and improve an efficiency of fuel consumption, by providing a method of detecting a state of deceleration of the engine, and a method of discriminating a deceleration for more than a prescribed length of time and a frequency of deceleration repetition.
CONSTITUTION: With a deceleration state detector 1 discriminating a state of deceleration and a switching made to an output of high level, an integral output of an integrator 2 is changed toward negative direction with the lapse of time. When lowered soon below the set value of a comparator 3, with one input of an AND circuit 4 becoming high level, at this time on condition that the state still be in deceleration, the AND circuit 4 outputs a fuel cutoff signal of 1. And after a release, if shifting again into a state of deceleration, an output of the integrator 2 is again changed into the negative side proportionally to the time of release, and at the time when becoming less than the set value of the comparator 3, the output of the AND circuit 4 again comes to be 1, and a feed of fuel is cut out.
