ABSTRACT:
A method of controlling the quantity of fuel to be injected into an intake manifold for an engine by a fuel injection unit comprising the steps of identifying parameters indicative of a change in the dynamic characteristic of the fuel supply system due to changes in the environmental conditions including the atmospheric pressure and engine temperature, estimating the quantity of fuel to be supplied to the engine cylinder on the basis of the identified parameters, and controlling the quantity of fuel to be injected so that the ratio between the measured quantity of air supplied to the engine cylinder and the estimated quantity of fuel supplied to the engine cylinder attains the desired air-fuel ratio.
