Injection quantity control apparatus provided to internal combustion engine

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.
