The invention discloses an engine cylinder cover water jacket which comprises a cylinder cover main water jacket body, a cylinder cover auxiliary water jacket body and a cylinder body water outlet water jacket body. The cylinder cover main water jacket comprises a water inlet, a combustion chamber cooling water jacket, an exhaust passage cooling upper water jacket and a water outlet, the water inlet is located in the air inlet side of an engine, and the water outlet is located in the rear end of the exhaust side of the engine. A first water jacket supporting part is further arranged on the side, away from the combustion chamber cooling water jacket, of the exhaust passage cooling upper water jacket, and an exhaust passage first cooling branch is arranged on the exhaust passage cooling upper water jacket; the combustion chamber cooling water jacket comprises an oil sprayer cooling water jacket, an air inlet channel cooling water jacket, a spark plug cooling water jacket, a nose bridge area cooling water jacket and a second water jacket supporting part. The cylinder cover auxiliary water jacket comprises an exhaust passage second cooling water jacket and an auxiliary water jacket supporting part, and the exhaust passage second cooling water jacket is located below the exhaust passage. According to the engine cylinder cover water jacket, the multiple cooling water jackets are arranged, the cooling capacity of the engine cylinder cover water jacket can be remarkably improved, and the heat dissipation requirement of an engine is met.
Description
Technical field [0001] The present invention relates to the field of engine technology, and more particularly to an engine cylinder head. Background technique [0002] As the national regulations are increasingly strict on energy conservation and environmental requirements, the thermal efficiency of the engine is also increasing, and the efficient combustion system and high compression ratio technology are also applied to the current gasoline engine. As the compression ratio is increased, the engine's knocking tendency is also increasing, which requires the engine cylinder cover with a strong cooling ability to reduce the temperature in the engine cylinder to reduce the engine's knock. The traditional technology of the engine cylinder head is poor, and the heat dissipation requirements of the engine have not been met. [0003] Therefore, there is an urgent need for an engine cylinder head. Inventive content [0004] It is an object of the present invention to provide an engine c...
