Abstract
A combustion prechamber is formed by at least two components. An upper component for accommodating an injection device, for example, and a lower component for sealing the prechamber off from the main combustion chamber. To configure such a combustion pre-chamber such that, without impairing the combustion process and the service life, instead of being welded, the connecting seam between the upper component and the lower component is notch-free and, at the same time, has a high strength, and is produced by a brazing process.
