Abstract:
A cylinder head for an internal combustion engine comprising a prechamber (3), wherein a prechamber gas valve (5) is fitted into a cavity of the cylinder head (2) and the prechamber gas valve (5) is connected to the prechamber (3) by way of a flow transfer passage (10), wherein the flow transfer passage (10) for a given cross-sectional area immediately downstream of the prechamber gas valve (5) is of such a length that in operation of the cylinder head (2) mounted in an internal combustion engine in a compression stroke of the combustion process propellant gas which flow out of the prechamber gas valve (5) forms a gas cushion at least in a first portion (8) of the flow transfer passage (10), that adjoins the prechamber gas valve (5).
