Abstract
A fuel injection control system and method for an internal combustion engine and an engine control unit, for accurately determining a fuel injection period and for performing accurate and optimum control of the actual fuel injection amount. An amount of fuel demanded by the engine is determined according to the detected operating conditions of the engine. An amount of fuel deposited on walls downstream of the fuel injection valve is determined according to the detected operating conditions. A net amount of fuel to be injected from the fuel injection valve is determined based on the determined demand amount of fuel and the determined deposited amount of fuel. Pressure of fuel to be injected from the fuel injection valve is determined. The fuel injection period is determined by correcting the determined net amount of fuel according to the determined pressure of fuel.
