PROBLEM TO BE SOLVED: To provide an engine control device capable of coping with waxing and freezing of fuel supplied as a lubricant, and capable of avoiding lubrication failure in gas oil fuel lubrication type engine using the fuel such as the gas oil as lubricating oil also. SOLUTION: The engine control device 1 is provided with a lubrication system fuel circulation circuit 3, an injection system fuel circulation circuit 4, an electric lubrication pump 6 incorporated in the lubrication system fuel circulation circuit 3, and ECU 12 for controlling operation of the electric lubrication pump 6. The engine control device 1 drives the electric lubrication pump 6 in accordance with the state such as the temperature of the fuel, and the fuel flows into the lubrication system fuel circulation circuit 3. Thereby, it is possible to cope with waxing and freezing of the fuel at the very low temperature, and lubrication failure such as runout of oil film and seizure at the time of start of the engine can be prevented.
