ABSTRACT:
A cylinder head of light metal for an air-compressing, self-igniting internal combustion engine which is provided with a vortex chamber that is delimited on the side of the main combustion space by an insert of a high heat-resistance material; the insert which preferably has an abutment collar is arranged in a stepped bore in the cylinder head bottom; a relatively high temperature is desired for the insert with the firing channel which is controlled by heat removal in particular into the cylinder head bottom; the abutment collar and the insert are spaced each exclusively within a section of the outer circumference facing a hot zone of the cylinder head bottom from the respective walls of the stepped bore; the spacing at the insert is smaller than the structural height thereof.
