Problems solved by technology
In the traditional body cooling water jacket structure, the water jacket near the cylinder jacket is generally of uniform width, that is, the width is the same. If the water jacket is thicker, the water flow will be too small. At the same time, it is necessary to dig holes between the two cylinder holes to improve the cooling effect. Not good, the support strength is also poor, and it is easy to cause the deformation of the body; if the thickness of the water jacket is narrow, there will be problems of high flow rate and large resistance
Therefore, the traditional body cooling water jacket structure cannot meet the actual needs of the engine

Embodiment Construction
[0023] The present invention will be further described below in conjunction with the specific embodiments in the accompanying drawings.
[0024] refer to Figure 1-7 As shown, the body cooling water jacket structure of a multi-cylinder engine of the present invention includes a horizontal water channel 1, a longitudinal water channel 2 and a plurality of cylinder liner water channels 3, and each cylinder liner water channel 3 is independently arranged on the cylinder liner 4 and the body 5 Between, that is, one cylinder liner 4 corresponds to one cylinder liner water channel 3, so that the two adjacent cylinder liner water channels 3 are not connected, and the coolant will not circulate between the cylinder liners, so that the coolant can be quickly taken away from the cylinder The heat of the outer wall of the jacket 4 further improves the cooling effect; wherein, the cylinder jacket water channel 3 includes an upper water jacket 6 and a lower water jacket 7, and the cross-se...

The invention discloses an engine body cooling water jacket structure of a multicylinder engine, belongs to the technical field of engine cooling, and solves the problem that the cooling effect is poor and the resistance is larger due to uniform width of a traditional engine cooling water jacket. The engine body cooling water jacket comprises a transverse water channel, a longitudinal water channel and a plurality of cylinder jacket water channels, wherein each of the cylinder jacket water channels is independently arranged between the cylinder jacket and the engine body; each of the cylinderjacket water channels comprises an upper water jacket and a lower water jacket; the cross section widths of the upper water jackets in the circumferential direction are equal; the cross section widthon the left and right sides of each of the lower water jackets is equal to the cross section width of each of the upper water jacket; and the cross section width on the front and back sides of each ofthe lower water jackets is greater than the cross section width of each of the upper water jacket. According to the engine body cooling water jacket structure, the cylinder jacket water channels adopt non-uniform width design, so that the water flow rate is effectively increased while ensuring the strength of the engine body, and the cooling effect is improved.
Description
technical field [0001] The invention relates to the technical field of engine cooling, more specifically, it relates to a cooling water jacket structure of a multi-cylinder engine body. Background technique [0002] During the manufacturing process of the engine, in order to cool the combustion chambers such as the engine piston, a cooling water jacket is usually arranged between the body and the cylinder liner. In the traditional body cooling water jacket structure, the water jacket near the cylinder jacket is generally of uniform width, that is, the width is the same. If the water jacket is thicker, the water flow will be too small. At the same time, it is necessary to dig holes between the two cylinder holes to improve the cooling effect. Not good, the support strength is also poor, and it is easy to cause the problem of body deformation; if the thickness of the water jacket is narrow, there will be problems of high flow rate and large resistance. Therefore, the traditio...
