Abstract
In an internal combustion engine comprising a cylinder block having at least one row of cylinders and at least one cylinder head, there are provided a coolant distributor passage for supplying a coolant from a pump to the water jacket of the cylinder block, first and second communication holes for allowing the coolant to flow from the cylinder block water jacket to the cylinder head water jacket, and a coolant collector passage for returning the coolant from the cylinder head water jacket to the pump. The coolant distributor passage and collector passages both extend along the cylinder row, one on one side of the cylinder row and the other on the opposite side. The distributor passage is formed in an upper portion of the cylinder block near the cylinder head. The collector passage is formed in the cylinder head. One longitudinal end of the collector passage is connected to the pump. The first communication holes are formed on the distributor passage's side and the second communication holes on the collector passage's side. The first and second communication holes are so sized that the total opening area of the first communication holes are larger than that of the second holes.
