Abstract
A cylinder head for a liquid-cooled multi-cylinder internal combustion engine, with a cooling chamber configuration adjacent to a fire deck, which is partitioned by an intermediary deck essentially parallel to the fire deck into a lower cooling chamber in the direction of the cylinder axis, where lower and upper cooling chambers are flow-connected by at least one main transfer opening for each cylinder in the area of the side wall of the cylinder head and by at least one auxiliary transfer opening in the region of a preferably central opening for the insertion of a fuel injection device. At least one auxiliary transfer opening is configured as a recess in the insertion opening, and at least one first auxiliary transfer opening is located in at least one of the areas between intake passage and insertion opening and/or exhaust passage and insertion opening.
