Abstract
In an internal combustion engine cylinder head for being clamped to a cylinder block for defining therewith a plurality of combustion chambers arranged in a row, the cylinder head is formed with three parallel coolant passages along the row of combustion chambers, a first, a second and a third one of those passages successively passing by intake ports, exhaust ports and roofs of the row of combustion chambers, respectively, each passage being independently connected at one end thereof with a coolant jacket of the cylinder block to receive coolant therefrom, so that three parallel coolant flows of a favorable triple distribution of flow rates are optionally established according to certain relative magnitudes of flow resistance of the three coolant passages.
