Abstract
An injection quantity control apparatus provided to an internal combustion engine having an injection nozzle which continuously injects fuel is provided. The apparatus includes a fuel quantity adjustment mechanism which has a static pressure chamber and a total pressure chamber to which a static pressure and a total pressure of an intake pipe of said engine are supplied, respectively, and adjusts an amount of fuel supplied to said injection nozzle in accordance with a dynamic pressure between a pressure of said static pressure chamber and a pressure of said total pressure chamber. The apparatus also includes a dynamic pressure corrector which corrects said dynamic pressure so that an air-fuel ratio of the engine is controlled to be substantially a target value. Thus, a desired air-fuel ratio can be achieved without a necessity of a manual operation by an operator.
