Systems for a pre-chamber
Methods and systems are provided for a pre-chamber. In one example, a pre-chamber comprises a plurality of slots fluidly coupling it to a primary combustion chamber. The plurality of slots comprising a plurality of corresponding flaps configured to direct gases through the plurality of slots.
1. A system, comprising:
a pre-chamber arranged in a volume of a primary combustion chamber, wherein the pre-chamber comprises a plurality of slots and a plurality of flaps shaped identically to the plurality of slots, wherein the pre-chamber further comprises a hole arranged at a bottom surface of the pre-chamber, wherein a size of the hole is less than a size of each slot of the plurality of slots and wherein there are no other inlets or outlets in the pre-chamber except for the plurality of slots and the hole.
2. The system of claim 1 , wherein a geometric center of the hole is aligned with a geometric center of a spark plug of the primary combustion chamber.
3. The system of claim 1 , wherein each of the plurality of slots and the plurality of flaps comprises a rectangular shape.
4. The system of claim 1 , wherein a shape of the hole is a different shape than a shape of the plurality of slots.
5. The system of claim 1 , wherein a shape of the hole comprises a circle.
6. The system of claim 1 , wherein the plurality of flaps and the plurality of slots are arranged symmetrically about a protection tube of the primary combustion chamber.
7. The system of claim 6 , wherein the plurality of slots extends through an entire thickness of the protection tube.
