ABSTRACT:
A method is disclosed for controlling the fuel injection system for an internal combustion engine having a fuel injector for injecting fuel by a series of steps including: determining whether the engine performs stable combustion at the engine start depending on operating conditions of the engine; setting a fuel injection pulse width for the fuel injector in accordance with the operating conditions of the engine; and then generating a first pulse at an intake stroke of the engine and a second pulse at an exhaust stroke of said engine, when the engine does not perform stable combustion at the engine start, a total width of said first and second pulses corresponding to the set fuel injection pulse width.
