Abstract
The invention provides an automobile engine air flow adjusting device, which is a venture, and is provided with an air inlet, an air outlet and a shrinking neck, wherein the shrinking neck is arranged between the air inlet and the air outlet, and a thread structure is arranged on the outer wall of the venture. The automobile engine air flow adjusting device can overcome the defect that an existing automobile air flow adjusting device is slow in heat dissipation.
Description
Technical field
The present invention relates to the motor vehicle components field, be specifically related to the air flow regulator of car engine.
Background technique
Hyundai Motor uses a kind of air flow regulator more and more, this device is a Venturi tube, usually be installed in the exhaust manifold of car engine, utilize venturi principle to regulate the flow velocity of air-flow, to impel fuel oil fully to burn or the exhaust pollutant content, for example the device of CN2668874Y, CN201090292Y, CN202176392U disclosure all belongs to similar device.
There is the slower defective of heat radiation in existing air flow regulator, usually cause high temperature at the controlling device place in the course of the work, it is aging ahead of time that this high temperature causes ternary to touch coal, and this place's high temperature also can make air flow regulator because expanding with heat and contract with cold by perishable or fracture.
Summary of the invention
The objective of the invention is to overcome the slower defective of existing Automobile air flow modulation device heat radiation.
The present invention proposes a kind of car engine air flow regulator, and it is a Venturi tube, have suction port, air outlet and the necking down between suction port and air outlet, and the outer wall of Venturi tube has worm structure.
Preferably, the outer wall of described Venturi tube has the concave surface that concaves.
In a kind of embodiment, described bottleneck is provided with ring gear.
In another kind of embodiment, suction port diameter R1〉air outlet diameter R2 constriction diameters R3, suction port to the distance L 1 between the necking down greater than necking down to the distance L 2 between the air outlet.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide a further understanding of the present invention, and the letter among the figure had both referred to associated components, represented again when needed its size.
Fig. 1 is the longitudinal sectional view of the air flow regulator of first embodiment of the invention;
Fig. 2 is the longitudinal sectional view of the air flow regulator of second embodiment of the invention;
Fig. 3 is the transverse sectional view at bottleneck of the air flow regulator of second embodiment of the invention.
Embodiment
Fig. 1 is the longitudinal sectional view of the first embodiment's air flow regulator.This device has suction port R1, air outlet R2 and necking down R3, and integral body is a Venturi tube.The present invention is provided with screw thread at this Venturi tube outer wall, and this screw thread has increased the heat diffusion area of Venturi tube, can improve heat dissipation rate.
As preferred setting, the outer wall of Venturi tube is the concave surface that concaves, and this can reduce the thickness of Wen's tube wall, and further increasing heat radiation area.
The size of suction port R1 and air outlet R2 can be identical, also can be different.As a kind of preferred setting, it is R1 that the diameter of suction port R1, air outlet R2 and necking down R3 is closed〉R2 R3, suction port R1 to the distance between the necking down R3 (import stroke) L1 greater than necking down R3 to the distance between the R2 of air outlet (outlet stroke) L2.In this embodiment, gas enters through larger diameter air inlet R1, arrive necking down R3 through a long distance L 1, the necking R3 suction of the exhaust that is come by engine and convergent are mixed, when fluid leaves necking down R3 discharged to the downstream enlarged section, expand gradually its diameter to air outlet R2 by R3, through one than short distance L2.In outlet stroke L2, fluid is subject to " extruding ", and forms one " flow-disturbing (turbulent flow) district " between necking down R3 and air outlet R2, more makes oil, gas mixing, under secondary combustion with imperfect combustion pollutant perfect combustion.
Controlling device of the present invention can be R1, R2 according to vehicle exhaust amount and the inner caliber size of outlet pipe, R3 adjusts, and can be installed on Motor Vehicle, general car, diesel-oil vehicle, LPG Car, lorry, Combination Truck Tractor-trailer.
Fig. 2 is the longitudinal sectional view of the air flow regulator of second embodiment of the invention.Itself and the first embodiment one significantly difference be the built-in ring gear D at necking down R3 place.As shown in Figure 3, ring gear D is to the outstanding a plurality of tooths of center of circle direction.This tooth can be pointed dentation, arc shape, sheet or other suitable shapes.This ring gear plays the flow-disturbing effect, so that mix more even through the fluid after the necking down.
Device of the present invention can be made by iron, stainless steel, aluminum alloy, Ti metal.Preferred material is Ti metal, because Ti metal hardness is high, high temperature resistant, corrosion-resistant, heat conduction is good, rapid heat dissipation, density are low.The NO that discharges when motor
xContain carbon, carbon can remain in the surface of apparatus of the present invention, makes the not residual carbon distribution of smooth surface in the surface by titanium metal material, and corrosion-resistant, heat conduction is good, the multiple advantages of rapid heat dissipation.
Air flow regulator of the present invention can make fuel oil fully burn, and carbon distribution had not both been saved the energy, had reduced again pollutant emission.In addition, because controlling device rapid heat dissipation of the present invention, avoided the high temperature generation, reduced nitrogen oxide production its can be used for useful fuel oil do the Motor Vehicle of power, such as gasoline car, diesel-oil vehicle etc.
The explanation of the embodiment of front can disclose general features of the present invention fully, so that other people are easily concrete application by existing knowledge these embodiments are adjusted and/or adaptations, these all do not depart from scope of the present invention, so these adjustment and revise the replacement that is equal to be considered as mode of execution disclosed in the present invention.
Claims (4)
