Patent ID: 6899063

Claim:
Cylinder head for a multi-cylinder liquid-cooled internal combustion engine, with a cooling chamber configuration adjacent to a fire deck, which is divided by an intermediate deck essentially parallel to the fire deck into a lower cooling chamber next to the fire deck and an upper cooling chamber adjoining the lower cooling chamber in the direction of the cylinder axis, wherein lower and upper cooling chambers communicate with each other via at least one first transfer opening, and wherein at least one first transfer opening is provided in an area of an opening receiving a centrally disposed fuel injection device, and wherein at least one coolant inlet per cylinder opens into the lower cooling chamber, and at least one coolant outlet departs from the upper cooling chamber, and wherein a lower cooling chamber is associated with each cylinder and the lower cooling chambers of at least two adjacent cylinders are essentially separated from each other by a partitioning wall and a coolant flow in the lower cooling chamber is essentially transverse to the cylinder head, and wherein the upper cooling chamber extends over at least two cylinders, wherein the first transfer opening and the opening receiving the fuel injection device are spatially separated by a defined minimum distance between the receiving opening and the transfer opening by a portion of the cylinder head, and wherein at least one first transfer opening is disposed in an area of at least one web between intake port and receiving opening and/or exhaust port and receiving opening.
