Fuel injection control apparatus and fuel injection control method
Abstract:
According to an internal combustion engine fuel injection control apparatus and control method, when an operating region of the engine shifts from a fuel cut region in which no fuel is injected to a low load region in which a small amount of fuel is injected, or visa versa, at least one pilot injection is executed ahead of a main injection in the low load region, and the number of pilot injections is determined according to the engine coolant temperature. This injection control makes it possible to ensure drivability while suppressing the amount of HC produced.
