Cylinder head, core for manufacturing such a cylinder head, method for manufacturing said cylinder head and vehicle

摘要

The cylinder head comprises an exhaust manifold (22), and a cooling circuit (40) fitted to inner side of the cylinder head by liquid coolant. The cooling circuit comprises a concave cooling chamber (52) laid between walls of the exhaust manifold to collect gas trapped in the cooling circuit, an outlet cavity (44) to collect the coolant flowing in the cooling circuit, a degazing groove connecting tip of the chamber for cooling at the cavity. The groove is inclined and shaped so that gas moves from the tip towards the cavity of the outlet. The cylinder head comprises an exhaust manifold (22), and a cooling circuit (40) fitted to inner side of the cylinder head by liquid coolant. The cooling circuit comprises a concave cooling chamber (52) laid between walls of the exhaust manifold to collect gas trapped in the cooling circuit, an outlet cavity (44) to collect the coolant flowing in the cooling circuit, a degazing groove connecting tip of the chamber for cooling at the cavity. The groove is inclined and shaped so that gas move from the tip towards the cavity of the outlet, and increases or extends horizontally in the operating position of the cylinder head. Independent claims are included for: (1) a core for manufacturing a cylinder head for an internal combustion engine; and (2) a process for manufacturing the cylinder head by molding.
