Abstract
A water-cooled internal combustion engine has a cylinder headprovided with a cylinder head water jacket Jthrough which cooling water flows. The cylinder head water jacket Jincludes a combustion chamber water jacketsurrounding combustion chambersand an exhaust passage water jacketaround an exhaust manifold passage. The exhaust gas discharged from the combustion chambersthrough exhaust portsflows through the exhaust manifold passage. The exhaust passage water jacketis divided into an upstream water jacketand a downstream water jacketby a partition wall. The cooling water flows from both the upstream water jacketand the downstream water jacketinto the combustion chamber water jacket. Equality in temperature between a combustion chamber wall and an exhaust passage wall is improved and the cylinder headis heated in a uniform temperature distribution.
