Abstract
Provided is a technique capable of suppressing the amount of fuel adhering to a wall surface of a cylinder in an engine whose wall surface temperature varies every cycle. An internal combustion engine control device that controls an internal combustion engine, which injects fuel into a cylinder and generates combustion by ignition, includes: a wall surface temperature calculation unit that calculates a wall surface temperature of the cylinder based on a pressure in the cylinder; and a combustion control unit that controls the combustion of the internal combustion engine based on the calculated wall surface temperature.
