Abstract
An internal combustion engine includes a level plate that is arranged between a cylinder head and a cylinder, is adjacent to a combustion chamber and is provided with at least one opening for at least one inlet valve and/or one outlet valve and/or at least one injection equipment or the like, the plate bordering on a level cylinder head bottom. In order to reduce the introduction of heat into the cylinder head in the easiest possible way, the diameter of the opening is larger than the valve seat for the inlet valve and/or for the outlet valve and the valve seat for the inlet valve and/or for the outlet valve is formed by the cylinder head or by a valve seat ring that is solidly connected thereto.
