A method for controlling hydrogen combustion in a hydrogen internal combustion engine system includes a combustion chamber linked to an intake port via an intake valve, the hydrogen internal combustion engine system comprising a piston slidably moving between a top dead center position and a bottom dead center position, characterized by 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.

A system and method for discharging condensation from an engine system is disclosed. The system includes a drainage pathway from an upstream body that collects water to a downstream portion of the air intake system. A controller may initiate a draining event upon determining a threshold amount of water has been collected in the upstream body.
