1-9. (canceled)
A prechamber for an internal combustion engine, comprising:
- a surface that is subjected to flow during operation of the prechamber and which is arranged at an inner side of the prechamber, wherein the surface has at least a first surface region and at least a second surface region, wherein the first surface region has a specific structure, wherein the second surface region is free from the specific structure.
A method for configuring and/or producing a prechamber for an internal combustion engine, comprising the steps of:
- providing a prechamber geometry of a prechamber having a surface that is subjected to flow during operation of the prechamber;
- simulating a gas flow at an inner side of the prechamber;
- identifying a surface region which is suitable for an application of the gas flow to the surface with regard to a stabilization of the gas flow;
- and
- providing a specific structure in the surface region, wherein the specific structure is provided so that the gas flow is applied to the surface in the region of the specific structure.
