Description
Technical field
The utility model is related to a kind of gas-oil separation device of automobile engine more particularly to a kind of labyrinth type oil-gas separation dresses
It puts.
Background technology
With the development of science and technology and the improvement of people's living standards, automobile have become the most important friendship of people's trip
Logical instrument.Automobile engine at work, due to that there are gap, can cause a part mixed between cylinder wall and piston, piston ring
Gas is closed, enters crankcase containing fuel oil, machine oil, vapor and other steam, causes the waste of fuel oil and machine oil.Currently the majority
Engine is united using positive crankcase ventilation system, using the negative pressure of inlet manifold, oil gas in a part of crankcase is made to pass through air inlet
Manifold returns to in-cylinder combustion, and machine oil steam therein is also inevitably consumed, and causes engine motor oil consumption high, simultaneously also
The serious carbon deposit of valve and combustion chamber can be caused to influence engine performance.Further, since band organic oil in engine crankcase gas blowby
Particle, machine oil can't burn completely, thus can be to burning and discharge has a negative impact.
Gas oil separation structure is that the machine oil oil droplet that will be carried in crankcase gas blowby separates, and the exhaust gas after separation passes through song
Crankcase ventilation pipeline introduces combustion chambers burn, and the oil droplet after separation is back in crankcase, so as to prevent consumption of lubricating oil mistake
The problems such as height, abnormal combustion.
In order to be effectively prevented machine oil exudation, many engines all employ labyrinth type cylinder head casing Oil-gas Separation dress at present
It puts, gas oil separation structure is is integrated in valve mechanism cover at present, and Pcv valve side, tonifying Qi side level-one separation labyrinth, labyrinth main body is one
Series of baffle plates.In a limited space, the oil-gas separation efficiency of existing product can not be further promoted simpler, at low cost.It passes
System oil gas crude separation structure, is felt structure, cyclone type structure or absolute construction mostly, occupied space is big, and cost is higher.
If patent CN201120045632.1 discloses a kind of double gas and oil separating plants of labyrinth type, which is included by setting
There is gaseous mixture entrance in what several partition plates that the side wall of the enclosing on cylinder head casing and the inside sidewalls are equipped with collectively formed
With the gas and oil separating plant main body of gas outlet, it further include with the matched oil-gas separating plate of gas and oil separating plant main body,
Gas and oil separating plant main body is the first oil-gas separation chamber and second by divides that are contour with side wall and being fixed in its side wall
Oil-gas separation chamber.The labyrinth channel of the separator of the patent is not to grow very much, there are oil gas separation it is poor the shortcomings of, usually
In order to promote oil gas separation, there is a need to further increases the path of gas channel by increasing the quantity of maze board.
However, the increase of maze board quantity necessarily causes the increase of set-up time and installation cost.
Therefore, it is necessary to provide it is a kind of it is simple in structure, occupy little space and low-cost labyrinth oil gas separator.
