Abstract
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.
Claims5
A controller for a hydrogen engine that uses hydrogen gas as fuel, the controller comprising a processor configured to:
- calculate a peak value of an in-cylinder pressure before ignition based on an operating state of the hydrogen engine;
- and
- when the peak value is greater than a threshold value, change a control content of the hydrogen engine such that the peak value becomes less than or equal to the threshold value.
