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).
Claims16
A prechamber system for an internal combustion engine, comprising:
- a prechamber having a wall,
- a spark plug having at least one electrode,
- a gas introduction device including a gas valve,
- a gas passage connecting the gas introduction device to the prechamber by way of an inlet opening,
- a riser passage for connecting the prechamber to a combustion chamber of the internal combustion engine, and
- a guide device for influencing the flow of the gas in the prechamber,
- wherein the guide device is arranged adjacent to the inlet opening in such a way that in operation, the volume of flow of hot gas reaching the electrode of the spark plug, which hot gas flows into the prechamber by way of the riser passage, is reduced in comparison to the volume of flow of hot gas that would reach the electrode of the spark plug with out the guide device, and
- wherein the guide device extends into the prechamber between the inlet opening of the gas passage and the spark plug.
A prechamber system for an internal combustion engine, comprising:
- a prechamber having a wall,
- a spark plug having at least one electrode,
- a gas introduction device including a gas valve,
- a gas passage connecting the gas introduction device to the prechamber by way of an inlet opening,
- a riser passage for connecting the prechamber to a combustion chamber of the internal combustion engine, and
- a guide device for influencing the flow of the gas in the prechamber,
- wherein the guide device is arranged adjacent to the inlet opening in such a way that in operation, the volume of flow of hot gas reaching the electrode of the spark plug, which hot gas flows into the prechamber by way of the riser passage, is reduced in comparison to the volume of flow of hot gas that would reach the electrode of the spark plug with out the guide device, and
- wherein the guide device is disposed between the inlet opening of the gas passage and the riser passage, the guide device having a through opening connecting the inlet opening and the riser passage.
