Abstract

PURPOSE: To improve responsive property by varying gain of an amplifier with position of a throttle to set gain of rotational speed feedback system to the optimum over the whole rotational speed range.
CONSTITUTION: By means of an amplifier 12 interlocked with a throttle (not shown) or throttle sensor 10 to vary its gain with a position of the trottle, are amplified the deviation signal Δe derived from the difference between actual rotational speed signal Pn of an engine rotational speed detector 2 and rotational speed setting signal En of the throttle sensor 10, so that an actuator 7 may be driven the fuel injection amounts may be controlled. Thus, fuel injection amount can be set to the opimum value over the whole range of the engine rotational speed.
