Abstract: The invention relates to a cylinder head (10) for a combustion engine, where the cylinder head (10) comprises one or more gas channels (18a, 18b) with a gas connection (20) to receive gas and which is connected with one or more valves (14,16) for control of gas supply and gas admission, where said one or more valves (14,16) are fitted on or in the cylinder head (10). The cylinder head (10) comprises an internal gas channel (18a, 18b) that runs from the gas connection (20) and internally in the cylinder head (10) to said one or more valves (14,16). Also described is a method for supply of prechamber gas in a cylinder head (10) belonging to a combustion engine, in which gas is led through an internal boring (22) that is connected with a gas channel (18a) integrated internally in the cylinder head (10), where the internal boring (22) runs into an prechamber (26) in the cylinder head (10).

Abstract: A valve system is described for a gas engine (20) comprising a number of valves (36, 44) that are arranged to regulate the amount and supply of gas into an inlet manifold (16) in the engine (20). The system comprises a valve housing (30) equipped with a centrally placed and linearly moving control valve (36) and a surrounding admission valve (44), where the admission valve (44) is arranged to rotate to regulate the amount of gas that is let into the valve housing (30).
