摘要

A cooling water flow reinforcing structure for vehicle engine is provided to enhance the efficiency of cooling the combustion chamber wall by directing the whole cooling water in the exhaust-side water jacket of the head toward the combustion chamber wall. A cooling water flow reinforcing structure for vehicle engine includes a cooling water guide unit(11) which is located on one side in an exhaust-side water jacket of a head. The cooling water guide unit directs the whole cooling water in the exhaust-side water jacket of the head toward a wall(20) of a combustion chamber, thereby enhancing the cooling efficiency.
