PURPOSE:To prevent engine stall by preparing a detection circuit which detects the degree of deceleration of revolution number, and when the degree of deceleration of the number of revolution of an engine is above a set value, by increasing the fuel recovery revolution number after the stop of fuel feeding higher than that in the case when the degree of deceleration is below the set value. CONSTITUTION:A deceleration detecting circuit 14 is constituted to generate the level signal (1) when the engine revolution number decreases at the rate more than a set deceleration, and generate the level signal (0) when the number of revolution of the engine decreases at the rate less than the set deceleraion, and the fuel recovery revolution number after the stop of fuel feeding which is determined by comparators 13 is controlled at a higher value, when the output of the detector 14 is (1) level, and at the value which introduces a normal set revolution number, when the output is (0) level. |
