Abstract

The application 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 head water jacket, and the cylinder body water jacket and the cylinder head water jacket are connected; the cylinder head water jacket includes a cylinder head water jacket , The water jacket on the cylinder head and the channel system; there is a flow channel on the water jacket of the cylinder body, and a liquid inlet on the water jacket of the cylinder head; the flow channel is connected with the liquid inlet, and the liquid inlet is connected to the exhaust of the water jacket under the cylinder head Side communication, the exhaust side of the cylinder head water jacket is connected with the intake side of the cylinder head water jacket, the air intake side of the cylinder head water jacket is connected with the cylinder head water jacket through the channel system, and the cylinder head water jacket’s air intake side Connected with the cylinder water jacket. This system enables the coolant to flow directly into the lower water jacket of the cylinder head through the flow channel integrated on the cylinder block, so that the cooler coolant can all flow through the exhaust side of the cylinder head, distribute evenly and then flow through the exhaust nose bridge of each cylinder area and around the spark plug hole, so that these high-temperature positions can be cooled most fully, effectively reducing the temperature in the nose bridge area of ​​the cylinder head.

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...
