Abstract

A cylinder head for air-compressing, self-ignition fuel-injection internal combustion engines has four valves per cylinder and an auxiliary combustion chamber between the inlet ducts of the inlet valves. In order to achieve a structurally stiff inclusion of the auxiliary combustion chamber in the cylinder head housing, the cylinder head top located between a coolant space and a control space is set at an angle in the transverse direction in such a way that the auxiliary combustion chambers are immediately adjacent to the cylinder head top and can be cast jointly with the cylinder head.
