Abstract

This application relates to the field of cylinder block water jacket technology and discloses a cylinder block structure that controls the cooling effect of the water jacket through plungers. The structure includes a cylinder block water jacket, a first plunger, and a second plunger. The outer side of the cylinder block water jacket consists of two shell layers. The first and second plungers are inserted between the two shell layers of the cylinder block water jacket. The length of the middle rod of the second plunger is greater than the length of the middle rod of the first plunger.

Description

Technical Field

[0001] This application relates to the field of cylinder water jacket technology, specifically a cylinder structure that controls the cooling effect of the water jacket through a plunger. Background Technology

[0002] The function of the cylinder block water jacket structure is to transfer the heat energy from the engine combustion chamber and the inner wall of the cylinder to the coolant through heat conduction. Since the liquid is fluid, it is circulated to the radiator by the water pump. The radiator dissipates heat from the coolant through the flow of outside air. Then, the coolant circulates back to the engine water jacket to receive the heat generated when the engine is working, and so on.

[0003] The existing cylinder block water jacket structure has the following problems:

[0004] Firstly, the flow direction of the water jacket is disordered, and the cooling water entering the pump flows in multiple directions;

[0005] Secondly, the flow velocity of the water jacket is inconsistent in different places, and there are even local stagnations in the water flow.

[0006] The two issues mentioned above affect the cooling performance of the engine block. Utility Model Content

[0007] To address the shortcomings of existing technologies, this application provides a cylinder block structure that controls the cooling effect of the water jacket through a plunger. This structure has the advantage of controlling and adjusting the flow direction and velocity of the cooling water in the water jacket, thus solving the problem of low cooling performance of the engine cylinder block.

[0008] To achieve the above objectives, this application provides the following technical solution: a cylinder block structure for controlling the cooling effect of the water jacket by a plunger, comprising a cylinder block water jacket, a plunger one and a plunger two, wherein the outer side of the cylinder block water jacket is composed of two shells, the plunger one and the plunger two are inserted between the shells on both sides of the cylinder block water jacket, and the length of the middle rod of the plunger two is greater than the length of the middle rod of the plunger one.

[0009] The improved cylinder block water jacket has two plungers, which can forcefully control the direction of the water flow in the water jacket cooling water and improve the cooling effect of the water jacket.

[0010] Preferably, the length of the gap formed between the middle of the second plunger and the inner side of the cylinder water jacket is greater than the length of the gap formed between the middle of the first plunger and the inner side of the cylinder water jacket.

[0011] In summary, this application includes at least one of the following beneficial effects:

[0012] 1. The improved cylinder block structure controls the cooling effect of the water jacket through plungers. The improved cylinder block water jacket is equipped with two plungers, which can forcefully control the water flow direction of the water jacket cooling water, improve the cooling effect of the water jacket, and thus improve the cooling performance of the engine cylinder block.

[0013] 2. The improved cylinder block structure, which controls the cooling effect of the water jacket through a plunger, allows the plunger to adjust the flow rate and velocity of the cooling water in the water jacket through the gap, thereby enhancing the cooling effect of the cylinder block water jacket and improving the engine cooling performance.

[0019] Please see Figs. 1-3 A cylinder block structure that controls the cooling effect of the water jacket by a plunger includes a cylinder block water jacket 1, a plunger 1 2 and a plunger 2 3. The outer side of the cylinder block water jacket 1 is composed of two shells. The plunger 1 2 and the plunger 2 3 are inserted between the two shells on both sides of the cylinder block water jacket 1. The length of the middle rod of the plunger 2 3 is greater than the length of the middle rod of the plunger 1 2. The length of the gap formed between the middle of the plunger 2 3 and the inner side of the cylinder block water jacket 1 is greater than the length of the gap formed between the middle of the plunger 1 2 and the inner side of the cylinder block water jacket 1.

[0020] With the above technical solution, when cooling water is introduced into the two shells of the cylinder water jacket 1 from the inlet, the flow rate and velocity of the cooling water in the water jacket are adjusted by the control of plunger 2 and plunger 3, thereby improving the cooling effect of the cylinder water jacket 1 and enhancing the engine cooling performance.
