Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model is be integrated in cyclinder head cover by deaerator for existing oil and gas separating system, only carry out an Oil-gas Separation, there is the problem that separation effect is low, a kind of oil and gas separating system is provided, by arranging independent external deaerator, make mixed gas by twice separation, be separated more thorough.
As shown in Figure 1 and Figure 2, a kind of oil and gas separating system of embodiment of the present utility model, described oil and gas separating system comprises: cyclinder head cover 1, second deaerator 2, first conduit 3, first return tube 4, second conduit 5 and the 3rd conduit 6 that are provided with the first deaerator; Wherein, the first port 21 of described second deaerator 2 is connected with one end of described first conduit 3, and the other end of described first conduit 3 connects the first port 11 of described cyclinder head cover 1; Second port 22 of described second deaerator 2 is connected with described first return tube 4, imports in the oil sump of automobile by described first return tube 4 by the machine oil after being separated; 3rd port 23 of described second deaerator 2 is connected with one end of described second conduit 5, is connected to the intake manifold of automobile by described second conduit 5; 4th port 24 of described second deaerator 2 is connected with one end of described 3rd conduit 6, before the other end of described 3rd conduit 6 is connected to automobile turbocharger compressor inlet by pressure regulator valve 7; The five-port 25 of described second deaerator 2 is connected with the crankcase of automobile.
In this embodiment, composition graphs 1 and Fig. 2, when high engine speeds high load, crankcase pressure is greater than the pressure of the 3rd conduit 6 before supercharger air compressor, first fuel-air mixture in crankcase enters into cyclinder head cover 1, and the first deaerator integrated in cyclinder head cover 1 carries out first time Oil-gas Separation.Afterwards, fuel-air mixture after first time Oil-gas Separation by the first port 11 of cyclinder head cover 1 through first port 21 of the first conduit 3 to the second deaerator 2 arranged separately, flow in the second deaerator 2 and carry out second time Oil-gas Separation, after secondary oil gas is separated, separation rate reaches requirement, can be flowed out by the second port 22 of the second deaerator 2 for isolated machine oil, recycle in the oil sump being imported to automobile by the first return tube 4, and for isolated waste gas in order to free from environmental pollution, derived by the 4th port 24 of the second deaerator 2, through the 3rd conduit 6, before pressure regulator valve 7 is connected to automobile turbocharger compressor inlet, through gas exhaust manifold until firing chamber is burnt.Be separated with the secondary oil gas arranging separately the second deaerator by the first deaerator of setting integrated in cyclinder head cover, improve the separation effect of Oil-gas Separation, avoid waste.
It is to be understood that establish low-pressure cavity and hyperbaric chamber in the second deaerator, be carry out Oil-gas Separation by hyperbaric chamber, and when transmitter low speed and load, Oil-gas Separation is carried out in low-pressure cavity in the work of high engine speeds high load.When low engine speed low-load, first fuel-air mixture in crankcase is entered in the second deaerator 2 by the five-port 25 of the second deaerator 2 and is separated, same can being flowed out by the second port 22 of the second deaerator 2 of isolated machine oil, recycle in the oil sump being imported to automobile by the first return tube 4, and now for isolated waste gas, be derived after the second conduit 5 flow into intake manifold until firing chamber is burnt by the 3rd port 23 of the second deaerator 2.And be greater than the pressure in crankcase due to the pressure of the 3rd conduit 6 before supercharger air compressor during low-load, therefore fresh air flow into the first deaerator in cyclinder head cover 1 successively from the 3rd conduit 6, second deaerator 2, first conduit 3, after flow to March axle box polishing in crankcase by cyclinder head cover 1, decrease crankcase due to gas and flow out the damage that arrangement works is caused.
Due to when high engine speeds high load, pressure in second deaerator is lower than gas exhaust manifold, exhaust manifold pressure is greater than the second deaerator, there will be gas flows back to the second deaerator through the second conduit situation from gas exhaust manifold, for avoiding the appearance of this situation, further, as shown in Figure 1, described second conduit 5 comprises: the first arm 51 and the second arm 52; One end of wherein said first arm 51 is connected with the 3rd port 23 of described second deaerator 2, the other end of described first arm 51 is connected through an one-way valve 8 one end with described second arm 52, and the other end of described second arm 52 connects described intake manifold.
The setting of above-mentioned one-way valve 8, makes gas can only flow from the first arm 51 to the second arm 52, and can not reverse flow, and like this, just avoiding gas exhaust manifold gas flows in the second deaerator 2, thus affects the normal work of the second deaerator.
Further, as shown in Figure 2, described cyclinder head cover 1 comprises: the second port one 2 be connected with crankcase; The second return tube 9 be connected with described oil sump, is imported to the machine oil after being separated in described oil sump by described second return tube 9.
Cyclinder head cover 1 comprises the second port one 2 be connected with crankcase, when can realize high engine speeds high load, in crankcase, air-fuel mixture gas flows in cyclinder head cover 1 and carries out first time Oil-gas Separation, the tonifying Qi to crankcase when also can realize transmitter low speed and load.And the second return tube 9 can recycle be imported in oil sump by the machine oil of the first deaerator separation in cyclinder head cover 1.
In sum, the oil and gas separating system of the utility model embodiment, by arranging independent external deaerator, when high engine speeds high load, twice separation is carried out to mixed gas, being separated more thorough, also to tonifying Qi in crankcase, the damage of device work can being reduced when low speed and load when being separated mixed gas.
The utility model embodiment still provides a kind of automobile, comprises oil and gas separating system as above.
The oil and gas separating system of this automobile, by arranging independent external deaerator, when high engine speeds high load, twice separation is carried out to mixed gas, be separated more thorough, also to tonifying Qi in crankcase, the damage of device work can be reduced when being separated mixed gas when low speed and load.
It should be noted that this automobile is the automobile applying above-mentioned oil and gas separating system, the implementation of above-mentioned oil and gas separating system is applicable to this automobile and also can reaches identical technique effect.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation " " be connected " " connection " etc. should be interpreted broadly, such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
