Abstract
This invention relates to a cylinder head (1) for a plurality of cylinders (A,B,C) for a liquid-cooled internal combustion engine, with a cooling chamber configuration (3) adjacent to a fire deck (2), which is divided by an intermediate deck (4) essentially parallel to the fire deck (2) into a lower cooling chamber (5) next to the fire deck (2), and an upper cooling chamber (7) adjoining the lower cooling chamber (5) in the direction of the cylinder axis (6), where lower and upper cooling chamber (5, 7) communicate with each other via at least one flow opening, and where at least one coolant inlet (13) per cylinder (A,B,C), which is preferably located in the fire deck (2), opens into the lower cooling chamber (5), and at least one coolant outlet departs from the upper cooling chamber (7). For the purpose of improved cooling a lower cooling chamber (5) is associated with each cylinder (A,B,C) and the lower cooling chambers (5) of at least two adjacent cylinders (A,B,C) are substantially separated from each other by a partitioning wall (12) and the upper cooling chamber (7) extends over at least two cylinders (A,B,C).
