Abstract
The invention provides a fuel supply control method and apparatus in which an air fuel ratio does not become rich even if an acceleration and deceleration operation is repeated for a short time in the case that a time lag with respect to a response from a detection of an acceleration state to a fuel amount increase is large, and troubles such as a black smoke generation from an exhaust pipe, an engine stop and the like are not generated. In a fuel supply control method of an internal combustion chamber for increasing an amount of a fuel for acceleration so as to inject from an injection apparatus, at a time of detecting a transient state at an accelerating time or the like on the basis of data such as an opening degree of a throttle valve and/or an air suction pressure, the method inhibits the fuel amount increase for acceleration on the basis of the detection of the transient state, if a total amount of an injection fuel per a unit time is more than a fixed value.
