Abstract
In a fuel control system for an internal combustion engine, fuel is injected in a quantity the direct delivery part of which provides a desired quantity of fuel to be actually fed to the engine together with the drawn part of the intake-manifold wetting fuel. The quantity of the intake-manifold wetting fuel on the basis of which the quantity of the drawn part is calculated is calculated on the basis of the quantity of the adhering part of the fuel which was injected by the preceding injection and the quantity of the residual part of the preceding intake-manifold wetting fuel.
