An internal combustion engine with at least one combustion chamber, at least one fuel delivery line for the delivery of fuel to at least one combustion chamber, and at least one differential pressure control valve for controlling the pressure in the at least one fuel delivery line. The at least one differential pressure control valve is configured to perform a valve opening or valve closing movement based on a pressure difference between the at least one fuel delivery line and a reference volume having a reference pressure. The internal combustion engine further includes at least one pressure relief valve, separate from the at least one differential pressure control valve, and configured to open to cause a pressure relief in the reference volume and a decrease in the reference pressure if a drop occurs in the power to be performed by the internal combustion engine.

Internal combustion engine

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

Cylinder head for an internal combustion engine

A cylinder head for an internal combustion engine comprising a prechamber (), wherein a prechamber gas valve () is fitted into a cavity in the cylinder head () and the prechamber gas valve () is connected to the prechamber () by way of a flow transfer passage (), wherein the flow transfer passage () has a first portion () adjoining the prechamber gas valve () and a second portion () into which the first portion () opens, wherein the second portion () extends at least around a part of a periphery of the prechamber (), wherein the second portion () has an uninterrupted peripheral surface apart from that opening () with which it passes into the prechamber ().

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.
