Problems solved by technology

[0003] The V-shaped engine adopts the middle part of two rows of cylinder blocks as the oil-gas separation chamber. Due to the limited space of the oil-gas separation chamber, the capacity of the oil-gas separation device may exceed the limit under the condition of high engine speed and heavy load, so that a large amount of oil is stored in the oil-gas separation chamber. internal, resulting in low separation efficiency of the system, and resulting in a large amount of oil carried out by the system
This requires an external oil and gas separator to meet the requirements of oil and gas separation capacity, but it will increase the difficulty and cost of the overall machine layout

Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention will be further described: as figure 1 As shown in -3, a compound oil-gas separation device is characterized in that: the gas guide pipe 1 and the oil return pipe 2 are connected at the air inlet of the oil-gas separation chamber at the rear end of the V-shaped engine, and the oil return pipe 2 is a "J"-shaped pipe It communicates with the oil pan; the oil return pipe inlet 3 is arranged at the bottom of the oil-gas separation chamber.

[0010] When the engine is running at high speed and heavy load, the oil-air mixture entering the oil-gas separation chamber enters the oil-gas separation chamber through the gas guide pipe 1, and the gas guide pipe 1 changes the direction of gas flow, so that the gas collides with the wall of the oil-gas separation chamber, thereby reducing the The flow rate of the oil-air mixture increases the separation capacity of the oil-gas separation chamber; at the same time, t...

Abstract

The invention relates to a composite oil-gas separation device, which is characterized in that: a gas guide pipe and an oil return pipe are connected at a gas inlet of an oil-gas separation cavity at the rear end of a V-shaped engine; the oil return pipe is a J-shaped pipe and is communicated with an engine oil dish; and an inlet of the oil return pipe is formed at the bottom of the oil-gas separation cavity. The separating capacity of the oil-gas separation cavity can be improved on the premise of not adding an oil-gas separator; and gas inlet and oil return are separated, and the separating efficiency of the oil-gas separation cavity is improved.

Description

Technical field: [0001] The invention relates to a composite oil-gas separation device for a V-type engine. Background technique: [0002] With the continuous development of automobile technology, the power of the engine is constantly increasing, and the amount of air leakage is also increasing accordingly. Due to the limitation of the structure, the position that can be used for oil and gas separation is getting smaller and smaller. How to ensure the performance and reliability of the oil-gas separation device and give full play to the function of the oil-gas separation device has become a problem that engine designers pay more and more attention to. [0003] The V-shaped engine adopts the middle part of two rows of cylinder blocks as the oil-gas separation chamber. Due to the limited space of the oil-gas separation chamber, the capacity of the oil-gas separation device may exceed the limit under the condition of high engine speed and heavy load, so that a large amount of o...
