Description

Technical Field

[0001] The utility model belongs to the technical field of motorcycle oil-gas separation air filters, and particularly relates to a motorcycle air filter with both engine oil waste gas separation and afterburning functions. Background Art

[0002] With the rapid development of the motorcycle industry and the increasing awareness of environmental protection, the performance optimization and emission control of motorcycle engines have become the focus of the industry's attention. In the motorcycle engine system, the air filter plays a crucial role. It is responsible for filtering the air entering the engine, removing dust, sand grains and other impurities therein, so as to protect the engine from wear and maintain its efficient operation.

[0003] During the operation of the engine, the high-temperature and high-pressure gas in the cylinder will penetrate into the crankcase through the fine gaps of the piston ring parts and generate engine oil vapor with the engine oil in the crankcase. To keep the air pressure in the crankcase stable, the engine oil vapor needs to be continuously discharged outwards. However, in existing motorcycles, the engine oil vapor is introduced into the air filter and then enters the cylinder to participate in combustion. Since the engine oil vapor burns incompletely, carbon deposits are formed, which aggravates the cylinder wear and shortens the service life of the engine. In addition, another part of the engine oil vapor will condense on the air filter element to form sludge, thus affecting the intake efficiency and reducing the output power and service life of the engine.

[0004] Therefore, the inventor is committed to designing an air filter to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a motorcycle air filter with both engine oil waste gas separation and afterburning functions, which helps to keep the inside of the engine clean, reduce carbon deposits and wear, and thus improve the power output and overall performance of the engine.

[0042] The working principle of the motorcycle air filter with both engine oil exhaust gas separation and afterburning in this embodiment is as follows:

[0043] The external air is purified by the air filter element 2 and then enters the cavity 14 to mix with the gas in the cavity 14. At the same time, the high-temperature exhaust gas discharged from the engine enters the exhaust gas oil path 13 from the oil-gas port 131, then enters the oil storage pipe 71 through the oil-gas hole 114, and finally enters the storage oil bottle 7. The K&N mushroom head in the storage oil bottle 7 separates the exhaust gas and stores the separated engine oil in the storage oil bottle 7.

Embodiment 2

[0045] Refer to Figure 12 and Figure 13This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: at the two oil and gas holes 114 at the bottom of the base 11 in this embodiment, a mushroom head 8 is connected through a tee-shaped direct exhaust pipe 81. The mushroom head 8 is a KMDM crankcase ventilation mushroom head, which is used to filter dust and moisture in the air, ensure that the crankcase ventilation gas is clean and dry, effectively prevent the phenomenon of engine oil emulsification, and guarantee the lubrication effect and heat dissipation performance of the engine. Other structures are the same as those in the first embodiment and will not be elaborated here.

[0046] The working principle of the motorcycle air filter that combines engine oil waste gas separation and afterburning in this embodiment is as follows:

[0047] The external air is purified by the air filter element 2 and then enters the cavity 14 to be mixed with the gas in the cavity 14. At the same time, the high-temperature waste gas discharged from the engine enters the waste gas oil path 13 from the oil and gas port 131, then enters the direct exhaust pipe 81 through the oil and gas holes 114, and is directly guided to the bottom of the vehicle for discharge after being filtered by the mushroom head 8.

[0048] The motorcycle air filter that combines engine oil waste gas separation and afterburning in this embodiment is of the direct exhaust type, and can directly guide the engine oil vapor discharged from the crankcase to the bottom of the vehicle for discharge. Its advantages include: First, it avoids the formation of sludge due to the condensation of engine oil vapor on the air filter element 2, ensures the intake efficiency, and improves the working performance of the engine; Second, it avoids the backflow of engine oil vapor to the cylinder, resulting in unburned engine oil entering the combustion chamber, causing the phenomenon of burning engine oil and the generation of carbon deposits, reducing wear, and prolonging the service life of the engine. Embodiment Three

[0049] Refer to Figures 14 to 17 This is the third embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: in the space at the upper end of each waste gas oil path 13 in this embodiment, an oil path gasket 9 is accommodated along the direction of the waste gas oil path 13, that is, the oil groove 112 part of the waste gas oil path 13 is blocked by the oil path gasket 9, and the bottom groove 116 part of the waste gas oil path 13 is not blocked. Oil and gas return bolts 91 are respectively provided at the two oil and gas holes 114 of the base 11, and an oil and gas inlet hole 911 is provided on each oil and gas return bolt 91. The oil and gas inlet hole 911 is communicated with the space at the lower end of the waste gas oil path 13. The oil and gas return bolt 91 can be communicated with the waste gas discharge port of the engine through a pipeline. Other structures are the same as those in the first embodiment and will not be elaborated here.

[0050] The working principle of the motorcycle air filter in this embodiment is as follows:

[0051] The external air is purified by the air filter element 2 and then enters the cavity 14 to be mixed with the gas in the cavity 14. At the same time, the high-temperature waste gas discharged from the engine enters the oil and gas inlet hole 911 of the oil and gas return bolt 91 through the conduit, then enters the waste gas circuit 13, and is introduced into the cylinder through the oil and gas port 131 to participate in secondary combustion.

[0052] The motorcycle air filter of this embodiment is a backfire type, which can introduce the oil vapor discharged from the crankcase into the air filter and then into the cylinder to participate in secondary combustion. Its advantages include: First, the transparent cover 3 allows users to intuitively feel the breathing process of the engine, and its unique appearance design enhances the driving experience; Second, the oil vapor is introduced into the throttle valve to participate in secondary combustion, reducing harmful substance emissions, reducing environmental pollution, and helping to improve the ecological environment.
