The invention relates to an automobile engine cooling water jacket structure integrating an exhaust manifold. The automobile engine cooling water jacket structure comprises a cylinder body water jacket, a cylinder cover water jacket and an air cylinder mat; the automobile engine cooling water jacket structure is characterized in that the cylinder body water jacket comprises a water passing way arranged on the air inlet side of an engine and a cylinder body water jacket body wrapping the air cylinder and communicating with the water passing way; and the cylinder cover water jacket comprises a burning chamber water jacket wrapping a burning chamber and communicating with the water passing way and an exhaust manifold water jacket wrapping the exhaust manifold and communicating with the burning chamber water jacket. By means of the automobile engine cooling water jacket structure, an air cylinder cover and an air cylinder body are better cooled, the cooling water distribution ratio of thecylinder body water jacket to the cylinder cover water jacket can be adjusted to enable the cooling effect on the air cylinder cover and the air cylinder body to be better, the more even air cylindertemperature can be guaranteed, the cooling strength of the burning chamber and the exhaust way zone can be adjusted, and the temperature of the burning chamber and the temperature of the exhaust way zone can keep coincident; and the cooling capacity of the exhaust manifold can be improved, and the reliability and the economical efficiency of the engine are improved.
