Description
Technical Field
[0001] The utility model relates to the technical field of motorcycle accessories, in particular to a motorcycle engine inner cavity breathing oil and gas condensation separation and drainage device. Background Art
[0002] As an internal combustion engine that relies on the reciprocating motion of pistons to execute its working cycle, a motorcycle engine operates with a delicate and complex mechanism. During the engine's operation, the pistons continuously reciprocate up and down, a motion that directly causes the engine's internal volume to cyclically change—occasionally expanding and contracting. This volume shift further triggers a phenomenon similar to "breathing," establishing a dynamic exchange of airflow between the engine and the external environment through the air duct.
[0003] Specifically, when the piston moves downward, the internal volume of the machine increases, forming a negative pressure, thereby "inhaling" the outside air through the air duct; when the piston moves upward, the internal volume decreases and the pressure increases, forcing the hot gas generated after combustion and the incompletely burned exhaust gas to be "exhaled" to the external environment through the air duct. It is worth noting that these exhaled hot gases not only contain pollutants such as carbon dioxide, water vapor and possible nitrogen oxides produced by combustion, but also carry oil vapor that evaporates due to high temperature during engine operation.
[0004] These oil vapors, as part of the engine's internal lubrication system, are evaporated into tiny particles under high temperature and high pressure and are discharged along with the exhaust gas. Since they contain substances harmful to the environment and human health, if they are directly discharged into the atmosphere without proper treatment, they will undoubtedly have a certain negative impact on the environment.
[0005] Therefore, the utility model proposes a motorcycle engine inner cavity breathing oil and gas condensation separation and drainage device to solve the above problems. Utility Model Content

[0025] For the purpose of simplicity and illustration, the principles of the embodiments are described primarily with reference to examples. In the following description, many specific details are provided to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring the understanding of these embodiments. In addition, all embodiments may be used in combination with each other.
[0026] Example 1: Please refer to Figures 1 to 7 The utility model provides a technical solution: a motorcycle engine inner cavity breathing oil and gas condensation separation and drainage device, comprising: an oil and gas condensation separator body 3, the oil and gas condensation separator body being hollow inside and having three joints, external pipes 11 being provided on both sides of the oil and gas condensation separator body, external threads 12 being provided on the surface of the external pipes 11, a first delivery pipe 2 and a second delivery pipe 4 being connected to both sides of the oil and gas condensation separator body respectively, the first delivery pipe 2 and the second delivery pipe 4 having the same structure, and a limit assembly 8 being provided on both the first delivery pipe 2 and the second delivery pipe 4;
[0027] A first sealing gasket 10 is fixed to the external pipe 11 near the oil-gas condensation separator body 3. A drain pipe 5 is connected to the bottom of the oil-gas condensation separator body. One end of the first delivery pipe 2 is connected to the air outlet of the motorcycle engine body 1, and the other end of the first delivery pipe 2 is connected to the oil-gas condensation separator body 3. One end of the second delivery pipe 4 is connected to the air filter body 6, and the other end of the second delivery pipe 4 is connected to the oil-gas condensation separator body 3.
[0028] During use, the oil-gas condensation separator body 3 is arranged between the motorcycle engine body 1 and the air filter body 6 to separate the oil and gas from the oil vapor, and only discharge the gas, thereby reducing the negative impact on the environment caused by directly discharging the oil vapor. In addition, the provided limit assembly 8 can be used to quickly connect the first delivery pipe 2, the second delivery pipe 4 and the oil-gas condensation separator body 3. After the oil-gas condensation separator body 3 has been used multiple times, it is convenient to inspect and replace the oil-gas condensation separator body 3.
[0029] Embodiment 2: On the basis of embodiment 1, an abutting end ring 21 is fixed at the end face of the first conveying pipe 2, and a second sealing gasket 23 is fixed on the surface of the first pipe. The second sealing gasket 23 is located next to the abutting end ring 21. An inner ring 17 is fixed on the surface of the first conveying pipe 2, and a guide rod 19 is slidably connected to the inner ring 17. There are several guide rods 19, and the guide rods 19 are equidistantly distributed on the inner ring 17. One end of the guide rod 19 is provided with a movable ball 22, and a top plate 26 is fixed on the guide rod 19. The top plate 26 is disc-shaped and is located next to the movable ball 22. A spring 18 is sleeved on the guide rod 19, and the spring 18 is located between the inner ring 17 and the top plate 26. One end of the spring 18 is fixedly connected to the top plate 26, and the other end of the spring 18 is fixedly connected to the inner ring 17. The inner fixed ring 24 is provided with an inner ring 17 groove on one side facing the bottom plate 16. The movable ball 22 contacts the bottom wall of the inner ring 17 groove and is rolled.
[0030] When in use, the first pipe and the second pipe have the same structure, so the overall setting mode of the second pipe and the limit assembly 8 is consistent with the overall setting mode of the first pipe and the limit assembly 8. When the delivery pipe and the external pipe 11 need to be connected, the specific operation is as follows: by holding the outer wall of the transmission pipe 14 and driving the transmission pipe 14 to move away from the end face of the delivery pipe, the inner fixed ring 24 will be moved, thereby driving the guide rod 19 to slide in the inner ring 17, thereby causing the spring 18 to be further compressed. At this time, the spring 18 is compressed to store elastic potential energy. When the end face of the connecting pipe 7 moves to the abutment end ring 21, the external pipe 11 is moved to the abutment end ring 21, and Slowly release the tension on the transmission tube 14, and match the internal thread 13 of the connecting tube 7 with the external thread 12 of the external tube 11. At this time, by rotating the transmission tube 14, the internal thread 13 and the external thread 12 are threadedly connected. With continuous rotation, the external thread 12 and the internal thread 13 are completely docked, thereby completing the installation operation. While the transmission tube 14 rotates, the movable ball 22 will continue to roll in the inner groove, and the spring 18 will continue to give a thrust to the transmission tube 14 and the connecting tube 7. When the installation is completed, the thrust still exists, which improves the stability of the connection between the delivery tube and the external tube 11 after installation. It is worth noting that the spring 18 is in a compressed state throughout the entire process.
[0031] The limiting assembly 8 includes a connecting tube 7, a transmission tube 14, and an inner fixing ring 24. The limiting assembly 8 is located on the periphery of the first transmission tube 2. A chassis 16 is fixed to one end of the connecting tube 7. One side of the chassis 16 is chamfered. The inner wall of the chassis 16 contacts and movably connects to the outer wall of the first transmission tube 2. The other end of the connecting tube 7 is fixedly connected to the connecting tube 7. The outer ring diameter of the chassis 16 is larger than the outer ring diameter of the transmission tube 14.
[0032] When in use, the chassis 16 provides a support for the palm when pulling the transmission tube 14, making it convenient to apply force. When the transmission tube 14 moves, the inner wall of the chassis 16 will contact the outer wall of the conveying tube, providing a support for the movement of the transmission tube 14 and the connecting tube 7.
[0033] Example 3: Based on Example 2, the connecting tube 7 is provided with an internal thread 13, which is thread-matched with the external thread 12. An inner fixing ring 24 is fixed to the inner wall of the transmission tube 14, and the inner fixing ring 24 is arranged close to the end face of the transmission tube 14. The outer wall of the transmission tube 14 is provided with anti-slip grooves 15.
[0034] One side surface of the inner fixing ring 24 facing the connecting pipe 7 contacts and tightly abuts the surface of the abutting end ring 21 , and the other side of the abutting end ring 21 contacts and tightly abuts the end surface of the outer pipe 11 ;
[0035] When in use, an external thread 12 is provided on the surface of the external tube 11, which is adapted to the internal thread 13 of the connecting tube 7 of the limiting assembly 8 to ensure the tightness and stability of the connection. The anti-slip grooves 15 provided on the outer wall of the transmission tube 14 increase the friction and facilitate installation and disassembly. After completing the connection between the oil and gas condensation separator body 3 and the delivery pipe, the first sealing gasket 10 will be tightly pressed against the end face of the connecting tube 7, and at the same time, the second sealing gasket 23 will be in contact with the inner ring 17 of the inner fixed ring 24, and at the same time, the abutting end ring 21 will be in contact with and tightly pressed against the end face of the external tube 11, effectively preventing oil and gas leakage and improving the sealing performance of the device.
[0036] Working principle: During actual use, the gas containing oil vapor exhaled by the motorcycle engine body 1 enters the oil-gas condensation separator body 3 through the first delivery pipe 2. The oil-gas condensation separator body 3 is shaped like a pig kidney, made of plastic, and is hollow inside. At this time, the gas will naturally expand when it encounters a loose space and mix with the cold air here. After being cooled, the oil vapor condenses on the four walls of the oil-gas condensation separator body 3. As the piston continues to move, fresh air is sucked into the engine, and the original oil vapor condenses and remains on the inner wall of the oil-gas condensation separator body 3. When it accumulates too much, it will be discharged from the drain pipe 5 along the inner wall, thereby realizing the separation of oil and gas in the oil vapor, only discharging gas, reducing the negative impact on the environment caused by directly discharging oil vapor, and using the set limit assembly 8, the first delivery pipe 2, the second delivery pipe 4 and the oil-gas condensation separator body 3 can be quickly connected. After the oil-gas condensation separator body 3 has been used many times, the oil-gas condensation separator body 3 is convenient for maintenance and replacement.
[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
