Abstract

The invention provides an engine cooling water jacket system, an engine cooling method, and a vehicle. The system includes a cylinder body water jacket and a cylinder cap water jacket, the cylinder body water jacket is connected with the cylinder cap water jacket, the cylinder cap water jacket includes a cylinder cap lower water jacket, a cylinder cap upper water jacket, and a channel system, a flow channel is arranged on the cylinder body water jacket, a liquid inlet is formed in the cylinder cap lower water jacket, the flow channel communicates with the liquid inlet, the liquid inlet communicates with the air discharging side of the cylinder cap lower water jacket, the air discharging side of the cylinder cap lower water jacket communicates with the air inletting side of the cylinder caplower water jacket, the air inletting side of the cylinder cap lower water jacket communicates with the cylinder cap upper water jacket through a channel, and the air inletting side of the cylinder cap lower water jacket communicates with the cylinder body water jacket. According to the system, cooling liquid flows to the cylinder cap lower water jacket directly through the flow channel integrated on a cylinder body, so that the cooling liquid with lower temperature can penetrate through the air discharging side of a cylinder cap totally, and penetrate through the peripheries of an air discharging noise bridge area and spark plug holes after being distributed evenly, so that positions with high temperature can be cooled fully, and the temperature of a noise bridge area of the cylinder capcan be effectively reduced.

Description

technical field [0001] The present application relates to the technical field of engine cooling, in particular to an engine cooling water jacket system, an engine cooling method and a vehicle. Background technique [0002] In order to make the engine structure design compact, reduce the size and reduce the number of parts, the modern supercharged engine usually adopts the cylinder head design with integrated exhaust manifold. [0003] In order to ensure the cooling effect and meet the requirements of the casting process, the water jacket of the cylinder head is usually designed in two pieces, namely, the upper water jacket of the cylinder head and the lower water jacket of the cylinder head. In some existing technologies, the design of the water jacket structure cannot reasonably distribute the coolant flow to the upper water jacket of the cylinder head, the lower water jacket of the cylinder head and the water jacket of the cylinder block, which will cause the nose bridge a...
