HYDROGEN MIXED-COMBUSTION ELECTRONIC CONTROL DEVICE AND POWER GENERATION SYSTEM USING SAME

A hydrogen mixed-combustion electronic control device that controls the mixed ratio of hydrogen mixedly combusted in a combustion room of a hydrogen mixed-combustion engine having a first fuel supply device that supplies first fuel to the engine and a second fuel supply device that supplies fuel partially containing hydrogen to the engine as second fuel comprises: a crank angle sensor that detects a rotation time of a crank shaft of the engine; and a computation unit that computes an extreme value of the rotation time of the crank shaft and an extreme value timing on the basis of a detection result of the crank angle sensor. The electronic control device determines a combustion state of the engine on the basis of the extreme value and the extreme value timing.
