Abstract
A fuel injection control system for an engine comprising: accelerating/decelerating state detection means which samples an intake pipe pressure of the engine at each sample timing which comes every time a very short time is passed from a timing at which a signal generator generates a signal at a reference crank angle position of the engine, and detects whether the engine is in an accelerating state or in a decelerating state when a difference between the intake pipe pressure sampled at each sample timing and an intake pipe pressure sampled at the corresponding sample timing one combustion cycle before exceeds a set value; and injector drive means which decides a fuel amount to be injected from an injector so as to be suitable for the detected state when the accelerating state or decelerating state is detected and drives the injector so as to inject the decided amount of fuel.
