Embodiment 1

[0018] figure 1 Shown is a schematic structural diagram of the oil-gas separator in the embodiment of the present invention. Such as figure 1 As shown, the oil-gas separator in the embodiment of the present invention includes a separation cavity, and an air inlet 4 and an air outlet 5 are formed on the separation cavity. Gas separation, the separated gas is discharged from the gas outlet 5, and the oil droplets return to the oil pan through the oil return pipeline. Wherein, the separation chamber includes a first separation chamber 1 and a second separation chamber 2 that are airtightly connected, and a labyrinth baffle group 6 is arranged in the first separation chamber 1, and the area where the labyrinth baffle group 6 is located forms a labyrinth. Separation zone; the second separation chamber 2 includes a cyclone separation zone, thereby forming a secondary oil-gas separation structure. A first liquid outlet (not shown in the figure) and an air inlet 4 are formed on the...

Embodiment 2

[0026] Based on the same inventive concept, an engine is provided in an embodiment of the present invention. The oil-air separator of the engine adopts the oil-air separator in Embodiment 1. Since the oil-air separation efficiency of the oil-air separator is improved, the oil and gas in the crankcase of the engine are reduced. Emissions caused by oil and gas.

[0027] Wherein, by effectively utilizing the internal space of the engine cylinder block, the first oil return pipeline can be formed on the inner wall of the engine cylinder block, specifically, it can be molded together with the engine cylinder block through a casting process, which is beneficial to reduce the occupied space of the engine. Further, by connecting one end of the first oil return pipeline to the air inlet of the oil-gas separator in airtight communication, while the other end is used as the crankcase air intake, the length of the air intake passage of the oil-gas separator can be greatly increased, making...

Embodiment 3

[0031] At the same time, the embodiment of the present invention also provides an automobile. The engine of the automobile adopts the engine in the second embodiment, and the emission problem caused by oil and gas in the crankcase of the engine is reduced, thereby reducing the emission problem of the automobile.

[0032] It can be seen from the above embodiments that the oil-gas separator provided by the present invention includes a first separation chamber and a second separation chamber that are connected. A plurality of labyrinth baffle groups are arranged in the first separation chamber to form a labyrinth separation area; the second separation chamber includes a cyclone separation area to form a secondary oil-gas separation structure. Among them, the first liquid outlet and the air inlet of the oil-gas separator are formed on the first separation chamber, and the second liquid outlet and the gas outlet of the oil-gas separator are formed on the second separation chamber, s...

Abstract

The invention belongs to the technical field of automobile structures, and discloses an oil and gas separator, an engine and an automobile. The oil and gas separator comprises a first separating cavity and a second separating cavity; the first separating cavity is hermetically communicated with the second separating cavity; a plurality of labyrinth barrier sets are arranged in the first separating cavity to form labyrinth separating areas; the second separating cavity comprises a cyclone separating area so as to form a secondary oil and gas separating structure; and a first liquid outlet and a gas inlet of the oil and gas separator are formed on the first separating cavity, and a second liquid outlet and a gas outlet of the oil and gas separator are formed on the second separating cavity, so that oil and gas mixtures are fed into the labyrinth separating areas at first, and oil and gas in the oil and gas mixtures are coarsely separated from each other in the labyrinth separating areas and then are fed into the cyclone separating area to be finely separated from each other. The oil and gas separator, the engine and the automobile have the advantages that the oil and gas separating efficiency of the oil and gas separator is greatly improved, the problem of emission due to oil gas in a crankcase of an existing engine is solved, and accordingly the problem of emission of an existing automobile is solved.

Description

technical field [0001] The invention relates to the technical field of automobile structures, in particular to an oil-gas separator, an engine and an automobile. Background technique [0002] In recent years, the global requirements for the automotive industry to solve environmental protection, energy and other issues have become higher and higher, especially emission issues. Among them, during the operation of the car, the emission problem caused by the oil and gas (including oil mist particles and hydrocarbon exhaust gas) that escapes from the engine cylinder into the crankcase has attracted more and more attention. [0003] At present, the oil and gas discharged from the crankcase are mainly separated by the oil and gas separator, so in order to reduce the discharge problem caused by the oil and gas in the crankcase, the separation efficiency of the oil and gas separator is very important, and the oil and gas separation in the prior art The device is a single separation ...
