The ECM calculates a peak value of an in-cylinder pressure before ignition based on the operating state of the hydrogen engine. When the peak value of the in-cylinder pressure before ignition exceeds a threshold value, the ECM performs an advancement correction of the ignition timing such that the peak value becomes less than or equal to the threshold value.

Exhaust gas control apparatus for internal combustion engine

A control device determines an operation amount of an actuator that regulates an intake air amount, on the basis of operation conditions of an internal combustion engine. The control device is configured to calculate an index value of a piston temperature of the internal combustion engine, and correct the operation amount to an operation amount that increases the intake air amount, when the calculated index value is a value corresponding to a higher temperature of the piston temperature than a threshold value of the index value corresponding to an upper limit threshold value of the piston temperature, at a time of deceleration in which an engine speed of the internal combustion engine decreases. As the index value, for example, the piston temperature which is estimated from a deviation between an inputted heat amount and a heat release amount of a piston can be used.
