<p>PROBLEM TO BE SOLVED: To provide an internal combustion engine control device capable of acquiring a temperature of a tip section of an injector and a heat quantity of a cylinder head without directly detecting the temperatures of a tip section of the injector and the cylinder head with a temperature sensor.SOLUTION: An internal combustion engine control device (100) comprises: a fuel inlet temperature acquisition section (101) which acquires a fuel inlet temperature of an injector on the basis of a pressure drop amount of fuel inlet pressure and fuel injection pressure when the injector injects fuel; and a head heat quantity acquisition section (101) which acquires a heat quantity of a cylinder head with the injector installed thereon on the basis of a difference between a temperature of a tip section of the injector and the fuel inlet temperature.</p> |
