Abstract
The invention relates to a combustion recess in the head of a piston for a diesel engine, the piston being provided with a cooling duct optionally existing in the form of a cooled ring carrier. This combustion recess has, in the radially outer edge area, an undercut which is formed such that the radially outer delimitation of the combustion recess is situated sufficiently near the cooling duct so that the cooling duct has a cooling effect upon the combustion recess.
