Any remaining engine oil that does not flow back completely through the oil return hole flows back through the first and second labyrinth inlets.

Description

Technical Field

[0001] This utility model relates to the field of motorcycle engine oil-gas separation technology, and in particular to a motorcycle engine oil-gas separation structure. Background Technology

[0002] Motorcycle engine oil-gas separation refers to the effective separation of oil vapor and mixed gas generated in the crankcase of a motorcycle engine through specific devices and technologies, preventing oil from entering the combustion chamber for combustion, thereby reducing oil consumption and emissions pollution.

[0003] However, existing technologies have some problems: in the existing motorcycle engine oil-gas separation structure, there is only one oil-gas separation inlet on the top cover and the housing. In order to achieve the oil-gas separation effect, the oil-gas separation chamber is often designed to be relatively large or complex. Therefore, it is necessary to provide a motorcycle engine oil-gas separation structure to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides a motorcycle engine oil-gas separation structure, which solves the technical problem of poor oil-gas separation effect in motorcycle engine oil-gas separation structures.

[0005] To solve the above-mentioned technical problems, this utility model provides a motorcycle engine oil-gas separation structure, comprising:

[0006] The enclosure includes a housing, a labyrinth cover, an oil-gas separation sealing gasket, an oil baffle, a first bolt, a second bolt, a first labyrinth inlet, a second labyrinth inlet, an oil return hole, an inlet area, an oil-gas separation labyrinth, and an outlet area. The labyrinth cover and the oil-gas separation sealing gasket are fixedly connected to the housing by the first bolt, and the oil baffle is fixedly connected to the housing by the second bolt.

[0007] Preferably, the labyrinth cover and the oil baffle are respectively fixedly connected to two different chambers on the housing.

[0008] Preferably, the first maze inlet is located on the side of the maze cover, and the second maze inlet is located at the bottom of the oil baffle.

[0009] Preferably, there are two oil return holes, and the two oil return holes are arranged symmetrically.

[0010] Compared with related technologies, the motorcycle engine oil-gas separation structure provided by this utility model has the following beneficial effects:

[0011] This utility model provides an oil-gas separation structure for a motorcycle engine. The air-fuel mixture can enter through the first labyrinth inlet and the second labyrinth inlet, where it collides and creates turbulence, achieving a certain oil-gas separation effect. The remaining air-fuel mixture passes through the oil-gas separation labyrinth, where the remaining oil is separated again and returned through the oil return hole. Any oil that cannot be completely returned through the oil return hole is then returned through the first labyrinth inlet and the second labyrinth inlet.

[0012] This utility model provides an oil-gas separation structure for a motorcycle engine. The labyrinth cover is provided with two oil return holes, and the oil separated from the air-fuel mixture can be returned through the oil return holes and the first labyrinth inlet and the second labyrinth inlet.

[0013] This utility model provides an oil-gas separation structure for a motorcycle engine. The air-fuel mixture enters from two different directions, the first labyrinth inlet and the second labyrinth inlet. The air-fuel mixture collides with each other, initially achieving the function of oil-gas separation. Subsequently, the oil-gas separation labyrinth does not need to be made particularly large or complex to achieve the oil-gas separation effect, allowing the engine oil in the air-fuel mixture to be separated out, and the remaining air-fuel mixture flows out from the outlet area.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example 1:

[0020] Please see Figure 1-3This utility model provides a technical solution: a motorcycle engine oil-gas separation structure, including: a housing 1, a labyrinth cover 2, an oil-gas separation sealing gasket 3, an oil baffle 4, a first bolt 5, a second bolt 6, a first labyrinth inlet 7, a second labyrinth inlet 8, an oil return hole 9, an inlet area 10, an oil-gas separation labyrinth 11, and an outlet area 12. The labyrinth cover 2 and the oil-gas separation sealing gasket 3 are fixedly connected to the housing 1 by the first bolt 5, and the oil baffle 4 is fixedly connected to the housing 1 by the second bolt 6.

[0021] In this implementation scheme, the air-fuel mixture can enter through the first labyrinth inlet 7 and the second labyrinth inlet 8, where it collides and causes turbulence at the inlet area 10, achieving a certain oil-gas separation effect. The remaining air-fuel mixture passes through the oil-gas separation labyrinth 11, where the remaining engine oil is separated again and returned through the oil return hole 9. The engine oil that cannot be completely returned through the oil return hole 9 is then returned through the first labyrinth inlet 7 and the second labyrinth inlet 8.

[0022] Example 2:

[0023] Please see Figure 1-3 As shown, based on Embodiment 1, this utility model provides a technical solution: the labyrinth cover plate 2 and the oil baffle plate 4 are respectively fixedly connected to two different chambers on the box body 1. The first labyrinth inlet 7 is located on the side of the labyrinth cover plate 2, the second labyrinth inlet 8 is located at the bottom of the oil baffle plate 4, and there are two oil return holes 9, which are symmetrically arranged.

[0024] In this embodiment: the labyrinth cover plate 2 is provided with two oil return holes 9. The oil separated from the mixture can be returned through the oil return holes 9 and the first labyrinth inlet 7 and the second labyrinth inlet 8. The mixture enters from two different directions, the first labyrinth inlet 7 and the second labyrinth inlet 8. The mixture collides with each other, which initially plays the role of oil-gas separation. Subsequently, the oil-gas separation labyrinth 11 does not need to be made particularly large or complex to achieve the oil-gas separation effect, so that the oil in the mixture is separated out, and the remaining mixture flows out from the outlet area 12.

[0025] The working principle of the motorcycle engine oil-gas separation structure provided by this utility model is as follows:

[0026] Implementation steps for the first innovation point:

[0027] Step 1: The air-fuel mixture can enter through the first labyrinth inlet 7 and the second labyrinth inlet 8, where it collides at the inlet area 10, creating turbulence and achieving a certain oil-gas separation effect. The remaining air-fuel mixture passes through the oil-gas separation labyrinth 11, where the remaining engine oil in the air-fuel mixture is separated again.

[0028] Step 2: The oil is returned through the oil return hole 9. Any oil that cannot be returned through the oil return hole 9 is then returned through the first labyrinth inlet 7 and the second labyrinth inlet 8.

[0029] Implementation steps for the second innovation point:

[0030] Step 1: The labyrinth cover 2 is provided with two oil return holes 9. The oil separated from the air-fuel mixture can be returned through the oil return holes 9 and the first labyrinth inlet 7 and the second labyrinth inlet 8. The air-fuel mixture enters from two different directions, the first labyrinth inlet 7 and the second labyrinth inlet 8, and the air-fuel mixture collides with each other, which initially plays the role of oil-gas separation.

[0031] Step 2: The subsequent oil-gas separation labyrinth 11 does not need to be made particularly large or complex to achieve the oil-gas separation effect, so that the oil in the mixture is separated out and the remaining mixture flows out from the outlet area 12.

[0032] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
