Oil-gas separator on motorcycle engine tank body

Abstract

The invention provides an oil-gas separator on a motorcycle engine tank body, and belongs to the technical field of motorcycles. The technical problem that because oil-gas separation can not be achieved until an independent oil-gas separator is fixed to a tank body of an existing motorcycle, the structure is complex is solved. The engine tank body comprises a vertical tank cover. The oil-gas separator is arranged inside the tank cover, and comprises an end cover and a surrounding plate. The surrounding plate and the tank cover are fixed to form an oil-gas separation cavity. A first separation plate and a second separation plate are fixed to the inner side of the surrounding plate and divide the oil-gas separation cavity into a first separation cavity body, a second separation cavity body and a third separation cavity body which are sequentially arrayed. A steam inlet is formed in the end cover. When the end cover is fixed to the other end of the surrounding plate, the steam inlet of the end cover is communicated with the first separation cavity; two oil return openings are formed in the lower portion of the surrounding plate, and a gas outlet is formed in the upper portion of the surrounding plate. The oil-gas separator has the advantages of being good in oil-gas separation effect and simple in structure.

Description

technical field [0001] The invention belongs to the technical field of motorcycles, and relates to an oil-gas separator on a motorcycle engine case. Background technique [0002] The oil-gas separator of existing motorcycle engine generally adopts labyrinth type oil-gas separator to realize, and labyrinth type oil-gas separator is connected in the cylinder head cover of motorcycle engine as independent parts. [0003] Usually, the oil-gas separator arranged on the cylinder head cover, because the motorcycle engine cylinder head cover needs to be disassembled or replaced related engine spark plugs and other parts, or the vibration of the cylinder head will easily lead to the decrease of the labyrinth seal. In addition, the cylinder head has a high thermal load, which greatly increases the probability of rubber or plastic sealing failure, which leads to the failure of the entire labyrinth. Therefore, under normal circumstances, the cost and material selection requirements of ...

AI Technical Summary

Problems solved by technology

[0003] Under normal circumstances, the oil-gas separator arranged on the cylinder head cover needs to be disassembled or replaced related engine spark plugs and other parts of the motorcycle engine cylinder head cover, or the vibration of the cylinder head can easily lead to a decrease in the labyrinth seal.

In addition, the cylinder head has a high thermal load, which greatly increases the probability of rubber or plastic sealing failure, which leads to the failure of the entire labyrinth.

Therefore, under normal circumstances, the cost and material selection requirements of the labyrinth oil-gas separator arranged on the cylinder head cover are relatively high, resulting in an increase in production costs, and maintenance is required after a period of use, which also increases the use cost.
