Abstract:
A fuel injection control device for an internal combustion engine, comprising:revolution determining means for determining revolution of the internal combustion engine; an injector for injecting fuel into the internal combustion engine; fuel injection control means for controlling the injection of fuel of the injector, wherein the fuel injection control means include engine-start-completion detecting means for detecting whether or not the internal combustion engine has started, and fuel-injection-amount correcting means for correcting the amount of fuel to be injected, after the engine has started, by an amount of fuel for correction obtained by considering the amount of fuel remaining uncombusted in an air intake valve when starting the engine and in accordance with one of the frequency of fuel injection, revolution of the internal combustion engine, and the elapse of time; and a load determining means for determining the load on the internal combustion engine and an engine-temperature determining means for determining the temperature of the internal combustion engine, wherein, in the fuel-injection-amount correcting means, the amount of fuel for correction is adjusted in accordance with the load on the internal combustion engine and the temperature thereof.
