Fuel Injection Control Device For Internal Combustion Engine

摘要

When fuel injection is carried out, an amount of deposit produced newly around a second injection hole is estimated on the basis of an amount of fuel injected from at least the first injection hole. The amount of produced deposit estimated every time the first fuel injection is carried out is integrated. When the integrated value of the amount of deposit reaches a set value, fuel injection in which the second injection hole is used is carried out to remove the deposit.
