Pre-chamber for an internal combustion engine and combustion engine

A system, comprising:

• a mixture flow guide configured to couple to a pre-chamber having a pre-chamber component coupled to a spark plug sleeve of an internal combustion engine, wherein the pre-chamber comprises a chamber formed by a peripheral wall of the pre-chamber component extending about a longitudinal axis and a bottom wall of the spark plug sleeve extending across the longitudinal axis, a first opening disposed in the bottom wall and configured to receive an igniter, and a second opening configured to introduce an air-fuel mixture into the chamber, wherein the mixture flow guide comprises one or more guiding walls in the pre-chamber component and a slot in the bottom wall of the spark plug sleeve, wherein the slot extends along the bottom wall at least from the peripheral wall over a distance toward the first opening, wherein the mixture flow guide is configured to guide the air-fuel mixture into the chamber as a mixture flow:
• oriented substantially transversely with respect to the longitudinal axis from the second opening of the chamber to at least a part of the chamber adjacent to the first opening.

A method, comprising:

• guiding an air-fuel mixture as a mixture flow into a chamber of a pre-chamber having a pre-chamber component coupled to a spark plug sleeve of an internal combustion engine via a mixture flow guide, wherein the chamber is formed by a peripheral wall of the pre-chamber component extending about a longitudinal axis and a bottom wall of the spark plug sleeve extending across the longitudinal axis, the pre-chamber comprises a first opening in the bottom wall of the spark plug sleeve and configured to receive an igniter and a second opening configured to introduce the air-fuel mixture into the chamber, wherein the mixture flow guide comprises one or more guiding walls in the pre-chamber component and a slot in the bottom wall of the spark plug sleeve, wherein the slot extends along the bottom wall at least from the peripheral wall over a distance toward the first opening, wherein the mixture flow guide is configured to guide the mixture flow:
• oriented substantially transversely with respect to the longitudinal axis from the second opening of the chamber to at least a part of the chamber adjacent to the first opening.
