Description

The automotive oil air separation

Technical field

The utility model relates to a kind of filtrating equipment that gas is filtered, and relates in particular to a kind of automotive oil air separation.

Background technique

Automobile engine crankshaft case secondary inflammable gas is one of important composition in the vehicle fuel system, and it couples together inflammable gas in the motor through pipeline and intake manifold.Its main task is to transmit the unburned utilizable secondary combustion gas that motor acting back produces, thereby the realization fuel oil is not wasted the raising fuel economy, guarantees that the oil consumption of automobile is stable, makes automobile obtain economic driveability.Yet; In the course of conveying of combustible gas, after the fluid of gas-entrained and impurity get into the burning of motor air chamber with gas, produce a large amount of carbon distributions and cover in the firing chamber through regular meeting; The carbon distribution that accumulates over a long period can increase oil consumption influence discharging, the big heavy discount of engine life.

The model utility content

For solving the deficiency that exists in the existing technology, the utility model provides a kind of impurities in waste gas composition that can effectively separate to reduce the automotive oil air separation of carbon distribution, and it is simple in structure, effectively raises engine life.

For realizing above-mentioned purpose; The automotive oil air separation of the utility model; Comprise sealing the fluid collection cylinder, be arranged on suction port and air outlet on the fluid collection cylinder; Suction port and air outlet be communicated with passage on be provided with the filter that the gas that has fluid that suction port is flowed into filters, in the fluid collection cylinder, be provided with gas that suction port is flowed into baffle liner to the filter channeling conduct.

As the qualification to aforesaid way, described filter is the tubular that places the inside and outside wall of fluid collection cylinder to have filtering hole, and the gas that baffle liner is accepted suction port is sleeved on the top of filter.

Further qualification as to aforesaid way is fixedly connected with diffusing cone in the bottom of filter, and described diffusing cone has the face that extends out greater than the filter diameter.

As the further qualification to aforesaid way, extending out mask has downward-sloping radian.

As the further qualification to aforesaid way, the described face of extending out is stepped.

As qualification to the utility model, the internal communication of described air outlet and filter.

Adopt technique scheme, be cushioned, guide through setting up baffle liner, make the gas that has fluid and impurity; Reduced to have of the impact of the gas of fluid and impurity to the fluid collection cylinder; And through setting up diffusing cone, realized disperseing, fluid has been got in the fluid collection cylinder be evenly distributed filtering the fluid that forms; And then the automotive oil air separation that makes the utility model is when being connected in the gas pipeline, to the tension equalizer of gas pipeline, stable.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:

Fig. 1 is the blast structural representation of the utility model;

Fig. 2 is the overall structure schematic representation under the utility model assembled state.

Among the figure: 1-fluid collection cylinder; The 2-filter; The 3-baffle liner; The 31-annular seating; 32-air-flow damping plate; The 4-suction port; The 5-air outlet; The 6-diffusing cone.

Embodiment

As shown in Figure 1; It is that the waste gas that has fluid with producing in the crankcase filters that the automotive oil air separation of the utility model mainly acts on; Its structure specifically comprises fluid collection cylinder 1, places the filter 2 in the fluid collection cylinder 1; Wherein, fluid collection cylinder 1 has the housing structure of sealing, and its top is provided with and is communicated with the suction port 4 that can the waste gas in the crankcase be imported fluid collection cylinder 1 with crankcase; Filter 2 is the cylinder-like structure that is installed in the inside center position of this fluid collection cylinder 1; Its periphery adopts copper material; And has filtering hole; The portion top position is provided with the air outlet 5 that is connected with the outside of fluid collection cylinder 1 within it, and this air outlet 5 is connected with intake manifold, to realize intake manifold and filter 2 inner being communicated with.

Below suction port 4, be provided with baffle liner 3; Baffle liner 3 has an annular seating 31 that cooperates with filter 2 outer wall suits, evenly is provided with the air-flow damping plate 32 of the inclination of several circumferentially extendings around the annular seating 31, is accepted by the air-flow damping plate earlier from the off-gas flows rapidly that suction port 4 gets into; After reducing speed on the air-flow damping plate flattens surely; Flow down from the interval between the air-flow damping plate again, thus the sidewall through filter 2, at this moment; Can be through the filtering hole of filter 2 sidewalls be set; Make the diameter of the aperture of filtering hole less than fluid and impurity, thereby make fluid and impurity be isolated in the outside of filter 2, gas then gets into the inside of filter 2 through filtering hole.

The bottom of filter 2 is provided with diffusing cone 6, the setting of diffusing cone 6, and the one, realized sealing to filter 2 bottoms; Do not get into the inside of filter 2 to prevent oil gas from passing through filtering hole, the 2nd, playing fluid and impurity that filter 2 is filtered carries out the effect of water conservancy diversion, and the structure of diffusing cone 6 is the circle urniform in the present embodiment; Can clearly find out by Fig. 1; It has three end differences, wherein, is positioned at the end difference at top and the bottom fastening of filter 2 and is connected to realize the sealing to filter 2 bottoms; The diameter that is positioned at middle part and two end differences of bottom is all greater than the diameter of the end difference that is positioned at the top; And be and increase form gradually; And then formed the face that extends out greater than filter 2 diameters; It is successively disperseed fluid and impurity when the fluid that flowed down by filter 2 outer walls and impurity are carried on as two end differences that extend out face, finally flow into uniformly in the fluid collection cylinder 1; In order to ensure fluid and the flow effect of impurity on diffusing cone 6, all has downward-sloping radian as this two-layer end difference that extends out face.

This automotive oil air separation is communicated with suction port 4 when work with the crankcase of automobile, air outlet 5 is communicated with the intake manifold of motor car engine; The waste gas that contains the organic oil particulate that in crankcase, produces is through above the suction port 4 entering fluid collection cylinders 1; After the barrier air of waste gas process baffle liner 3 became steadily, from the below of baffle liner 3 inflow fluid collection cylinders 1, the filtering hole of process filter 2 got into below the inside of filter 2 then; Pass in the process of filtering hole at waste gas; The machine oil particulate that it contains condenses into bigger drop at filter screen, and along the extending out under the surface current of diffusing cone 6, is collected in the bottom of fluid collection cylinder 1; After filtering waste gas arrives the inner and upper of filter 2, and through the air outlet 5 flow into automobiles intake manifold.
