ABSTRACT:
A fuel injection control system assumes fuel amount introduced in an engine combustion chamber on the basis of an air/fuel ratio dependent value derived by monitoring an air/fuel ratio dependent component in an exhaust gas, and an intake air amount introduced into the combustion chamber, assumes wetting fuel amount to be consumed for wetting an induction system on the basis of the fuel amount introduced into the combustion chamber and a fuel injection amount injected up to the immediately preceding fuel injection cycle, and prospect fuel amount to be introduced into the combustion chamber on the basis of the current fuel injection amount and the wetting fuel amount. The prospected fuel amount to be introduced into the combustion chamber is compared with a target fuel amount which is derived according to the engine driving condition for modifying the fuel injection amount so that the prospected fuel amount coincides with the target fuel amount.
