Method for controlling hydrogen combustion in a hydrogen internal combusting engine

A method for controlling hydrogen combustion in a hydrogen internal combustion engine system comprising a combustion chamber linked to an intake port via an intake valve, and linked to an exhaust port via an exhaust valve, the hydrogen internal combustion engine system further comprising a piston slidably moving between a top dead center position and a bottom dead center position, wherein the method comprises the steps of:

• injecting water in liquid phase in the intake port when the piston is between 0 and 40 crank angle degrees before opening of the intake valve,
• injecting hydrogen after opening of the intake valve and when the piston is between 0 and 60 crank angle degrees after the top dead center position,
• stopping hydrogen injection when the piston is between 0 and 100 crank angle degrees before the bottom dead center position.
