Abstract
The utility model relates to a kind of integrated spiral formula cylinder head cover oil-gas separation mechanism, comprise the cylinder head cover with oil and gas import and oil gas vent, the Oil-gas Separation path formed between described oil and gas import and oil gas vent is provided with oil baffle, also comprise spiral oil-gas separation mechanism, and described spiral oil-gas separation mechanism is by flanging welded on described oil baffle, and described spiral oil-gas separation mechanism comprises barricade guide openings, separator inlet, separator volute chamber and is positioned at the separator outlet at separator volute chamber center.Oil-gas separation mechanism of the present utility model effectively solves that cylinder head cover built-in labyrinth type oil-gas its disengagement efficiency is low, and independent deaerator takies the large problem of arrangement space, has the feature of easy for installation, low cost of manufacture and long service life.
Description
Technical field
The utility model relates to the technical field of Vehicle Engine Structure design, and more particularly, the utility model relates to a kind of integrated spiral formula cylinder head cover oil-gas separation mechanism.
Background technique
In prior art, cylinder head cover Oil-gas Separation mostly is independent agency or built-in labyrinth type oil-gas separating mechanism, and its shortcoming is: (1) uses independent oil-gas separation mechanism to increase system development costs; (2) dismounting is complicated, and assembly cost is high, takes up room and is unfavorable for that greatly complete machine is arranged; (3) many employing labyrinth type oil-gas separating mechanisms in conventional cylinder housing, separation effect is low, and engine oil carrying quantity is unfavorable for greatly the available ventilation of crankcase.
Model utility content
In order to solve above-mentioned technical problem of the prior art, the purpose of this utility model is to provide a kind of integrated spiral formula cylinder head cover oil-gas separation mechanism.
To achieve these goals, the utility model have employed following technological scheme:
A kind of integrated spiral formula cylinder head cover oil-gas separation mechanism, comprise the cylinder head cover with oil and gas import and oil gas vent, the Oil-gas Separation path formed between described oil and gas import and oil gas vent is provided with oil baffle, it is characterized in that: also comprise spiral oil-gas separation mechanism, and described spiral oil-gas separation mechanism is by flanging welded on described oil baffle, and described spiral oil-gas separation mechanism comprises barricade guide openings, separator inlet, separator volute chamber and is positioned at the separator outlet at separator volute chamber center.
Wherein, described cylinder head cover is become by aluminum alloy cast appearance.
Compared with prior art, integrated spiral formula cylinder head cover oil-gas separation mechanism described in the utility model has following beneficial effect:
(1) effectively to solve cylinder head cover built-in labyrinth type oil-gas its disengagement efficiency low for oil-gas separation mechanism of the present utility model, independent deaerator takies the large problem of arrangement space, has the feature of easy for installation, low cost of manufacture and long service life.
(2) aluminum alloy of cylinder head cover use described in the utility model, not only casting processability is good, and the cylinder head good thermal stability formed, and heat distortion amount is little, and has good anti-fatigue performance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of integrated spiral formula cylinder head cover oil-gas separation mechanism described in embodiment 1;
Fig. 2 is the schematic diagram of spiral oil-gas separation mechanism in oil-gas separation mechanism described in embodiment 1;
Fig. 3 is the schematic diagram of oil gas flow path in the oil-gas separation mechanism of embodiment 1.
Embodiment
Be further elaborated integrated spiral formula cylinder head cover oil-gas separation mechanism described in the utility model below with reference to specific embodiment, to help, those skilled in the art conceives model utility of the present utility model, technological scheme has more complete, accurate and deep understanding.
Embodiment 1
As shown in Fig. 1 ~ 2, integrated spiral formula cylinder head cover oil-gas separation mechanism described in the present embodiment, comprise the cylinder head cover 11 with oil and gas import 1 and oil gas vent 4, the Oil-gas Separation path formed between described oil and gas import 1 and oil gas vent 4 is provided with oil baffle 3, comprise spiral oil-gas separation mechanism 2 in addition, and described spiral oil-gas separation mechanism 2 is welded on described oil baffle 3 by flange 9, described spiral oil-gas separation mechanism 3 comprises barricade guide openings 5, separator inlet 6, separator volute chamber 7 and be positioned at the separator outlet 8 at separator volute chamber center.Fuel-air mixture enters from oil and gas import, by spiral oil-gas separation mechanism after the speed-raising of barricade guide openings, enter separator inlet, centrifugal motion is done in volute chamber, Oil-gas Separation is realized under centrifugal action, isolated machine oil flows through oilhole under gravity and finally flows back to oil sump, and mixed gas then escapes from volute chamber from separator outlet, and the mixed gas after separation flows out cylinder head cover from oil gas vent after breeze way.The present embodiment is by integrated oil-gas separation mechanism, and reasonably optimizing structure, saves arrangement of mechanism space, and reduce development cost.By self helix structure, fuel-air mixture is accelerated in volute chamber, and realize Oil-gas Separation under the influence of centrifugal force, oil-gas separation efficiency can be made to significantly improve, thus reduce the impact of vehicle exhaust on atmosphere environment, improve emission performance and the economic performance of vehicle.The present embodiment is by mechanism ingehious design, the machine oil that realization has been separated and mixed gas move toward one another effect, namely machine oil moves downward under gravity naturally, to be fallen oil return pond by the oilhole that falls, mixed gas then escapes from volute chamber by perforate above volute chamber, thus avoid the oil gas be separated again to be dispelled and the possibility taken away by the mixed gas of high-speed motion, and realize separation effect maximization.For the cylinder head cover of certain 2.0T supercharging type, the oil-gas separation mechanism of the present embodiment is placed in air chamber, uses STAR CCM+ software modeling to analyze, can 5.48E+01 be reached through primary Calculation monomer separation efficiency.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technological scheme is carried out; or design of the present utility model and technological scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
