Fuel supply control device for internal combustion engine

Abstract

Abstract PURPOSE:To prevent decrease of output due to shortage of fuel immediately after acceleration by keeping the acceleration increase from being stopped regardless of such a little decrease of speed not to change the intake air quantity after acceleration. CONSTITUTION:Fuel supply quantity arithmetic means compute the fuel supply quantity according to the engine speed, the intake air quantity, cooling water temperature and so on. Acceleration and deceleration judging means judge acceleration or deceleration according to a detection value from throttle valve opening detection means, and according to the judgement, acceleration increase decreasing correction means gradually decrease the acceleration increase correction at a designated time after acceleration is judged. The acceleration increase correction stop means are adapted to stop the acceleration increase correction only when a throttle valve opening becomes smaller enough to change the air intake quantity.
