Abstract
An internal combustion engine control device includes a correlation index estimation unit configured to estimate a piston temperature correlation index correlated with a temperature of a piston based on an internal combustion engine operating condition parameter and an oil jet parameter for injecting oil to a back surface of the piston; and a hydraulic pressure setting unit configured to set a hydraulic pressure of an oil jet based on the piston temperature correlation index and an evaporation parameter of fuel attached to the piston, wherein when the piston temperature correlation index is less than a first predetermined value determined based on a temperature corresponding to a fuel evaporable condition as the evaporation parameter, the hydraulic pressure setting unit sets the hydraulic pressure of the oil jet to a hydraulic pressure at which oil jet injection can be stopped.
