Abstract
A pre-chamber system for an internal combustion engine has a pre-chamber having a wall, a spark plug having at least one electrode, and a gas introduction device, particularly a gas valve. A gas channel connects the gas introduction device to the pre-chamber via an inlet opening. A riser channel connects the pre-chamber (2) to a combustion chamber of the internal combustion engine. A guiding device influences the flow of the gas in the pre-chamber, the guiding device being arranged adjacent to the inlet opening in such a manner that in operation, the volume flow of hot gas flowing into the pre-chamber via the channel (8) and reaching the electrode (13) of the spark plug (4) is reduced by the guiding device (9).
