Abstract:
This invention relates to a deposit remove amount estimation device for estimating inlet and outlet deposit remove amounts by calculating an inlet deposit remove amount which is an amount of a removed combustion product among the combustion product accumulating on an injection hole inlet area and an outlet deposit remove amount which is an amount of a removed combustion product among the combustion product accumulating on an injection hole outlet area. In this invention, the inlet deposit remove amount is calculated on the basis of the inlet deposit accumulation amount which is an amount of the combustion product accumulating on the injection hole inlet area and the outlet deposit remove amount is calculated on the basis of the outlet deposit accumulation amount which is an amount of the combustion product accumulating on the injection hole outlet area.
