摘要： This control device for an engine provided with a fuel supply system capable of supplying liquefied natural gas to the engine as fuel comprises: a control unit for calculating a feedback adjustment value on the basis of a deviation between an actual fuel supply quantity and a target fuel supply quantity, and performing feedback control of the fuel supply system on the basis of the calculated feedback adjustment value; an acquiring unit for acquiring a methane number of the liquefied natural gas; a correcting unit for correcting the feedback adjustment value on the basis of the acquired methane number; and a failure diagnosis unit for performing failure diagnosis of the fuel supply system on the basis of the corrected feedback adjustment value. The engine control device can allow the failure diagnosis of the fuel supply system to operate normally.
