Abstract: 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.

Abstract: A pre-chamber component for an internal combustion engine includes a chamber for accommodating an air-fuel-mixture to be ignited, wherein the pre-chamber component includes a first opening into the chamber for arranging an ignition device, in particular a spark plug, and a second opening for introducing the air-fuel-mixture in the form of a mixture flow into the chamber. The pre-chamber component includes a mixture flow guiding device, which is shaped such that the mixture flow of the air-fuel-mixture in the chamber is oriented substantially transversely with respect to a longitudinal axis from the second opening of the chamber to at least a part of the chamber adjacent to the first opening and/or in the form of a turbulent flow.
