Abstract: 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.

Abstract: A first intake manifold is connected to a first group of cylinders, a second distinct intake manifold is connected to a second group of cylinders and a first, respectively a second, exhaust manifold for receiving the exhaust gas emitted from the first, respectively the second, group of cylinders. An EGR line is connected to the first and second exhaust manifolds. A mixing unit includes a four-way valve having a first inlet connected to an air line, a second inlet connected to the EGR line, a first outlet connected to the first intake manifold and a second outlet connected to the second intake manifold. The first inlet is connected to the air line, the second inlet is connected to the EGR line. The first outlet and said second outlet form a substantially X-shape. The first inlet and said second inlet are coaxial. The first outlet and second outlet are coaxial such that the first inlet is diagonally facing the second inlet and the first outlet is diagonally facing the second outlet.
