Problems solved by technology
[0003] In the above technical solution, after the coolant enters the water jacket of the multi-cylinder cylinder block through the water inlet on the machine body, the cylinder close to the water inlet is first cooled, and then the other cylinders are cooled in order. During the circulation of the coolant, without cooling For the rear cylinder, part of the coolant directly enters the cylinder head water jacket, which will result in less coolant flowing through the rear cylinder than the front cylinder, uneven coolant flow, and poor cooling effect
At the same time, the water inlet is facing the cylinder liner of the first cylinder, and the coolant keeps impacting the cylinder liner of this cylinder, which is easy to cause cavitation corrosion of the cylinder liner of this cylinder

Embodiment Construction
[0012] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0013] like figure 1 As shown, the multi-cylinder cylinder block water jacket of the present invention is mainly provided with a water baffle 2 at the water inlet 1 of the body. Split flow, according to which to distribute the flow of coolant in the multi-cylinder water jacket, to achieve uniform distribution of coolant in the multi-cylinder water jacket, the improvement is simple, but the cooling effect is significantly improved.
[0014] like figure 2 As shown, the multi-cylinder cylinder block in this embodiment includes the first cylinder block water jacket 3, the cylinder block water jacket and the cylinder head water jacket 6 are communicated through the cylinder head upper nozzle 5, and the cylinder block wate...

The invention discloses a multi-cylinder air cylinder body water jacket which is arranged in an air cylinder body. Various air cylinder body water jackets are mutually communicated and are communicated with corresponding air cylinder cover water jackets through water openings on cylinder covers. The multi-cylinder air cylinder body water jacket is characterized in that a machine body water inlet is formed in the air cylinder body and is communicated with the multi-cylinder air cylinder body water jacket, and a water partition plate is arranged at the machine body water inlet. The multi-cylinder air cylinder body water jacket structure enables cooling liquid flowing through every air cylinder body water jacket and every corresponding air cylinder cover water jacket to be even and remarkable in cooling effect. Meanwhile, the cooling liquid cannot impact a first air cylinder sleeve so as to avoid the cavitation erosion of the first air cylinder sleeve.
Description
technical field [0001] The invention relates to the field of engine cylinders, in particular to a multi-cylinder cylinder block water jacket. Background technique [0002] The cylinder block water jacket is a cooling water circulation channel designed inside the engine to cool down the high temperature parts of the engine. The coolant circulates in the water jacket to achieve the effect of heat dissipation. The structure of the water jacket has a great influence on the circulation of the coolant. The general engine The cooling liquid circulation method is as follows: first, the water pump presses the cooling liquid from the water inlet at the front end of the cylinder block, directly enters the oil cooler, and cools the oil through the cooling fins of the oil cooler. Then, the coolant cools the cylinder block and the cylinder head. When cooling the cylinder block, the coolant enters the water jacket of the multi-cylinder cylinder block through the water inlet on the body, an...
