Abstract
An electronic control device for mixed hydrogen combustion includes a combustion timing detection unit that detects the combustion timing of an engine; and an abnormal state detection unit that detects an abnormal state, in which a type of abnormality occurring in the engine has been determined, on the basis of the combustion timing and a second fuel supply ratio calculated from the supply amount of hydrocarbon fuel supplied by a first fuel supply device and the supply amount of a second fuel supplied by a second fuel supply device. A control mode determination unit determines a control mode corresponding to the abnormal state, controls the supply amount of hydrogen to be supplied by the second fuel supply device on the basis of the control mode, and outputs the control mode to an engine controller for controlling the engine.
