Description

Technical Field

[0001] The utility model relates to the field of engine cylinders, and specifically relates to an engine cylinder with high strength and corrosion resistance. Background Art

[0002] The engine cylinder is an important part of the engine cylinder. The engine cylinder is usually a cylindrical hollow component installed inside the engine block. It, together with the piston and piston rings, constitutes the combustion chamber and working space of the engine. Generally, an engine has multiple cylinders, and the number depends on the type of the engine. Common ones include four-cylinder, six-cylinder, eight-cylinder, etc. The cylinder provides an accurate guide for the up-and-down movement of the piston. The piston makes a reciprocating linear motion inside the cylinder, and transmits power to the crankshaft through the connecting rod to achieve the power output of the engine. At present, the temperature of the existing engine cylinder is relatively high during operation, and the heat cannot be dissipated in a short time, resulting in increased corrosion of the internal materials due to overheating. Therefore, an engine cylinder with high strength and corrosion resistance is needed.

[0003] For the existing engine cylinder, during use, it is inconvenient to dissipate heat and cool down the cylinder, thus reducing the strength and durability of the cylinder material, making the cylinder more prone to damage phenomena such as deformation and cracks, shortening the service life of the engine, and the corrosion resistance of the inner wall of the cylinder is poor. Over time, small corrosion points will appear on the inner wall of the cylinder, and these corrosion points will continue to expand, resulting in an increase in the roughness of the inner wall of the cylinder and affecting the smooth movement of the piston. Therefore, an engine cylinder with high strength and corrosion resistance is urgently needed. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an engine cylinder with high strength and corrosion resistance to solve the problems that the existing engine cylinder is inconvenient to dissipate heat and cool down the cylinder and the corrosion resistance of the inner wall of the cylinder is poor.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An engine cylinder with high strength and corrosion resistance, including an engine cylinder main body. A sealing gasket is installed on the outer wall of the engine cylinder main body. A convex block is fixedly connected to the top of the sealing gasket. A coolant injection hole is opened inside the engine cylinder main body. A diversion groove is opened inside the engine cylinder main body. Heat dissipation fins are fixedly connected to the outer wall of the engine cylinder main body.

[0006] A silicon carbide ceramic layer is fixedly connected to the inner wall of the engine cylinder main body. A polymer coating is fixedly connected to the inner wall of the silicon carbide ceramic layer.

[0007] Preferably, the engine cylinder main body is of a slotted design, and the engine cylinder main body is snap-fitted with the sealing gasket through the convex block.

[0008] Preferably, the bumps are symmetrically arranged with respect to the central axis of the sealing gasket, and the sealing gasket is sleeved on the outer wall of the engine cylinder block main body.

[0009] Preferably, the heat dissipation fins are located in the flow guiding grooves, and the heat dissipation fins are of an open-hole design.

[0010] Preferably, the engine cylinder block main body and the silicon carbide ceramic layer are closely attached, and the engine cylinder block main body and the silicon carbide ceramic layer are arranged in parallel.

[0011] Preferably, the silicon carbide ceramic layer and the polymer coating are closely attached, and the silicon carbide ceramic layer and the polymer coating are arranged in parallel.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By providing the engine cylinder block main body, the coolant injection hole, the flow guiding grooves and the heat dissipation fins, when the coolant is injected into the coolant injection hole, the coolant can flow along the flow guiding grooves through the outer wall of the engine cylinder block main body and be discharged from the bottom of the engine cylinder block main body. Since the heat dissipation fins are fixedly connected to the outer wall of the engine cylinder block main body, the engine cylinder block main body can conduct heat to the heat dissipation fins. Due to the open-hole design of the heat dissipation fins, the coolant can flow through to take away the heat, achieving the effect of facilitating the heat dissipation and cooling of the engine cylinder block main body, improving the heat dissipation effect of the engine cylinder block main body, preventing damage phenomena such as deformation and cracks of the engine cylinder block main body due to overheating, and increasing the service life of the engine.

[0014] 2. By providing the engine cylinder block main body, the silicon carbide ceramic layer and the polymer coating, the structural strength and corrosion resistance of the engine cylinder block main body can be improved by fixedly connecting the silicon carbide ceramic layer to the inner wall of the engine cylinder block main body. The corrosion resistance of the engine cylinder block main body can be further improved by fixedly connecting the polymer coating to the inner wall of the silicon carbide ceramic layer, increasing the service life of the engine cylinder block main body and enabling the piston to move smoothly.

The bump 3 is symmetrically arranged with respect to the central axis of the sealing gasket 2, and the sealing gasket 2 is sleeved on the outer wall of the engine cylinder block main body 1. The heat dissipation fins 6 are located inside the flow guide groove 5, and the heat dissipation fins 6 are of an open-hole design, which can facilitate the heat dissipation and cooling of the engine cylinder block main body 1, improve the heat dissipation efficiency, and prevent the engine cylinder block main body 1 from being damaged due to overheating, such as deformation and cracks.

[0023] Please refer to Figures 1-4 , an engine cylinder with high strength and corrosion resistance, a silicon carbide ceramic layer 7 is fixedly connected to the inner wall of the engine cylinder block main body 1, a polymer coating 8 is fixedly connected to the inner wall of the silicon carbide ceramic layer 7.

[0024] Working principle: When in use, by moving the engine cylinder block main body 1, making it pass through the sealing gasket 2, and driving the bump 3 to be butted and clamped into the engine cylinder block main body 1, the engine cylinder block main body 1 can be stably installed in the cylinder block. By injecting coolant into the coolant injection hole 4, the coolant can flow along the diversion groove 5 through the outer wall of the engine cylinder block main body 1 and be discharged from the bottom of the engine cylinder block main body 1.
