Abstract:
A fuel injection system comprising:fuel injectors provided for each of cylinders in an internal combustion engine, the fuel injectors supply fuel to each of the cylinders; a temperature detecting means for detecting temperature relating to an operating condition of the internal combustion engine; base control means for controlling the fuel injectors so that each of the cylinders is supplied with base injection amounts; correcting means for correcting the base injection amounts based on injection correction amounts so as to suppress the engine revolution speed change caused by differences of combustion power between the cylinders; storing means for storing the injection correction amount in connection with the temperature detected by the temperature detecting means; and initial value obtaining means for obtaining an initial value of the injection correction amount in the correcting means when the correcting means starts or resumes the correcting process, the initial value of the injection correction amount is obtained on the basis of the stored value of the injection correction amount in the storing means.
