摘要：PURPOSE:To provide proper fuel increase with a simple device by judging the cylinder wherefrom fuel is injected immediately before acceleration, allowing this cylinder to make additional injection at the normal timing after acceleration to have control so that fuel increase is made. CONSTITUTION:If acceleration is made immediately after injection of fuel from, for ex., No.5 cylinder in a 6-cylinder engine in which fuel injection is made in the sequence as 1, 5, 3, 6, 2, and 4, first the acceleration is sensed by a control unit 15 in which output signals from a crank angle sensor and throttle opening sensor are fed. After the cylinder from which the fuel is injected (No.5 cylinder) immediately before sensing of acceleration is judged, No.5 cylinder shall make additional injection at the timing of No.3 cylinder injection. Injection after sensing of acceleration (No.3 cylinder) shall be in the amount as the additional injection being added to normal injection. The No.6 and No.2 cylinders shall inject also the amount as additional injection being added to normal injection.
