Abstract

A compression ignition internal combustion engine having at least one combustion chamber for high ignition pressures. Each combustion chamber comprises a cylinder bore in the crankcase or a cylinder liner in the cylinder bore, a piston, and a cylinder head. Spaces for conveying coolant are disposed in the crankcase such that coolant flows about walls of the cylinder bore or a liner. The cylinder head has coolant chambers. The internal combustion engine has a separate cooled plate disposed between the combustion chamber and the cylinder head. The cooled plate forms a surface cover of the combustion chamber and is connected in a positively engaging and gas tight manner with the crankcase and/or the cylinder liner. Valve seats for at least one inlet valve and at least one outlet valve are disposed in the cooled plate, and at least one injection valve extends through the cooled plate.
