Abstract
The invention relates to a gas-oil separator of an engine with high gas-oil separating efficiency and low resistance. The technical proposal is as follows: the gas-oil separator of the engine is characterized in that vanes, a filter element and a rotation shaft are arranged, wherein, the vanes and the filter element are fixed on the rotation shaft which is arranged on a shell. The gas-oil separator combines the structural features of a filter element type gas-oil separator and a cyclone type gas-oil separator, the gas from a crank case is separated by the vanes for the first time and by the filter element once again, meanwhile, as the filter element can rotate, oil drops attached to the filter element can be separated from the filter element under the action of centrifugal force, thus effectively reducing the resistance of the filter element, achieving the optimal gas-oil separating effect and lowering the resistance of the system.
Description
Technical field
The present invention relates to engine crankshaft ventilation system, especially relate to a kind of oil-gas separating device for engine.
Background technique
The available engine crankcase ventilation system adopts mazy type or cyclone type oil-gas separator more.The mode of the realization Oil-gas Separation of labyrinth type oil gas separating device is: when fuel-air mixture during through the labyrinth; Because inertia; Little oil droplet in the mixed gas can be run on the wall of labyrinth, and under wall flow, the gas in the mixed gas then gets into crankcase ventilation system through the labyrinth smoothly.The separate mode of cyclone type oil-gas separator is similar with the labyrinth type oil gas separating device, and only the little oil droplet in the mixed gas is run into the wall of deaerator under action of centrifugal force, under wall flow.
The characteristics of these two kinds of deaerators are that resistance is little, non-maintaining; Shortcoming is that separation effect is low, also has the fraction motor to adopt the filer element type deaerator, is characterized in that separation effect is high, resistance is big; After particularly adhering to a certain amount of machine oil on the filter core, the resistance of filter core can be bigger.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of oil-gas separating device for engine, and Oil-gas Separation efficient is high, resistance is little.
Realize the object of the invention technological scheme:
A kind of oil-gas separating device for engine is characterized in that: have blade, filter core, rotatingshaft, wherein blade, filter core are fixed on the rotatingshaft, and rotatingshaft is contained on the housing.
The beneficial effect that the present invention has:
The present invention has combined the structural feature of filer element type and cyclone type oil-gas separator; Crank case gases carries out secondary separation through filter core again after blade carries out first separation, simultaneously because filter core can produce rotation; Make adhesion oil droplet above that under action of centrifugal force, break away from filter core; Can effectively reduce the resistance of filter core, reach best oil gas separation, reduce system resistance simultaneously.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
As shown in the figure, oil-gas separating device for engine has housing 1, blade 3, filter core 2, rotatingshaft 4, and wherein blade 3, filter core 2 are fixed on the rotatingshaft 4, and rotatingshaft is contained on the housing 1.
Be between blade 3, filter core 2, the rotatingshaft 4 and be rigidly connected, filter core is positioned at the top of blade.Housing 1 is provided with the rotatingshaft mounting hole, and housing can be arranged on valve chamber cover, timing cover or the crankcase, also can be integrated with valve chamber cover, timing cover or crankcase, and make engine structure more compact.
Arrow is depicted as the flow direction of crank case gases among the figure.Crank case gases at first drives filter cores 2 moving axis 4 rotations that rotate through blade 3, and the crank case gases Radial Flow produces cyclonic separation simultaneously, can separate the bigger oil droplet of diameter in the crank case gases.Then, crank case gases separates through filter core again, falls owing to the bigger oil droplet of diameter is separated, has so just reduced the resistance of filter core greatly; Simultaneously,, make adhesion oil droplet above that under action of centrifugal force, break away from filter core, further reduced the resistance of filter core because filter core produces rotation.Isolated machine oil under the effect of gravity under the wall flow of housing 1, flow out through the outlet of housing 1 upper end through the crank case gases of filter core.
Along with the increase of engine load, piston air leakage and engine oil carrying quantity all increase to some extent, and under the effect of crank case gases, the blade rotational speed also can be faster, and the efficient of deaerator will be higher like this.
