Abstract
An internal combustion engine, in particular a gas Otto-cycle engine, is provided. The internal combustion engine comprises a plurality of cylinders. Each cylinder is provided with a pre-chamber, and a pre-chamber gas supply conduit through which the pre-chamber can be supplied with fuel gas. The fuel gas is supplied to the pre-chambers by way of a pre-chamber gas valve associated with the respective pre-chamber. Also, an aperture is arranged between the pre-chamber gas supply conduit and the pre-chamber gas valve. At least one aperture associated with a pre-chamber gas valve has a through-flow coefficient such that pressure occurring at a maximum between combustion cycles in a volume between the pre-chamber gas valve and the aperture does not reach a pressure prevailing in the pre-chamber gas supply conduit.
