Zusammenfassung:PROBLEM TO BE SOLVED: To surely cool an intake air and to miniaturize a water pump by segregating a cooling water circulating path for an exhaust port side water jacket from that for other part water jackets. SOLUTION: A water jacket inside a cylinder head is partitioned into a water jacket 6 in an intake port side and a water jacket 8 in an exhaust port side. The cooling water circulating path 25 of the water jacket 8 which is another system from the cooling water circulating path 18 of the water jacket 6 is formed of cooling water passages 20, 22 and a heater core 21. This constitution can accurately cool the circumference of an intake and a combustion chamber by the cooling water circulating the circulation path 18. The water pump 11 just circulates the circulating path 18 for the cooling water of the water jacket 12 and the water jacket 6 so that the water pump 11 can be miniaturized.
