Abstract
PURPOSE: To prevent ignition failure or insufficient torque by providing an accelerating pulse generating circuit.
CONSTITUTION: An acceleration pulse generating circuit 5 for producing an acceleration pulse signal of a time width corresponding to the opening speed of a throttle valve 7 is provided between a throttle sensor 6 and an OR circuit 2. As the throttle valve 7 is progressively opened at the time of the engine acceleration, a slide 6 is separated from a contact 6a, and an accelerating pulse generating circuit 5 produces an accelerating pulse signal of level "1", which is coupled through an OR circuit 2 and an output circuit 3 to an electromagnetic injection valve 4 for suppoying fuel for acceleration to the engine independently of a main pulse signal from a main cauculating circuit 1. Meanwhile, at the time of sudden acceleration the time width of the accelerating pulse signal is increased to increase the rate of supply of accelerating fuel, thus permitting smooth engine acceleration.
