Abstract

A fuel control apparatus for an internal combustion engine (100) that is able to mix a first fuel with a second fuel that is higher in compression ignitability than the first fuel and then to use the mixture of the first fuel and the second fuel, includes a combustion pressure acquisition unit (62) that acquires a pressure in a combustion chamber (12) in which the first fuel and the second fuel are combusted; and a fuel control unit (60) that changes a percentage of the first fuel in fuel used on the basis of a maximum pressure at the time of combustion in the combustion chamber (12).
