FUEL INJECTION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine that can control a fuel amount injected from a cylinder injection valve properly so as to provide desired air-fuel ratio regardless of an operational state of an internal combustion engine.SOLUTION: The fuel injection control device for an internal combustion engine includes: additional injection means that, when the operational state of the internal combustion engine is determined to be a transient state, executes additional injection of injecting an additional fuel amount from the cylinder injection valve so as to correspond to an intake air amount that changes according to the transient state; subtraction means that subtract a fuel amount as much as the minimum injection amount of the cylinder injection valve from the injection fuel amount before the additional injection.SELECTED DRAWING: Figure 1
