Embodiment:

This fuel engine efficient mass transfer device is mounted between motor air feed main and cylinder.This device is comprised of interface bolt 1, shell 2, annular oriffice 3, frequency conversion air pump 4, fuel nozzle 5, conical surface diffusion disc or the dull and stereotyped diffusion disc 6 of circle, grid group 7, differential pressure flow sensor 8, temperature transducer 9.Thereafter 10 is air intake branch of the engine, the 11st, and fuel engine, be shown in Fig. 1.Frequency conversion air pump 4, grid group 7, differential pressure flow sensor 8, temperature transducer 9 all are connected with electronic control unit ECU.Grid group 7 can be fixed mesh group or movable adjustable grid group.The fixed mesh group is rectangle, polygonal, roundness mess composition with the multi-disc eyelet, sees Fig. 2.Movable adjustable grid group can be rotated grid group for fin, and it is the grid group changed with throughput by the multi-disc open degree that fixedly glazing bar 12 and rotating vane 17 form, and its pushing structure, on supporting plate slideway 20, consists of the cross bar 23 of spring 12 promotions; The moving mesh group is the regulatable grid group of barrel hole size, and its driving mechanism can be different versatile and flexible with the structure of application engine and oil circuit.The first rotating vane grid group of releasing of the present invention, grid and the accessory thereof variable by the multi-disc aperture form.Every slice graticule be many fixedly glazing bar 12 use links 13 connect into integral body.Grid is gone up most by being fixed on for many rotating shafts 14, the top cover 15 on bottom rail glazing bar 12 back sides supports fixing.Fin 17 1 sides are connected in rotating shaft 14, and opposite side has a plurality of winglet wings 18 vertical with fin 17, form the rotating vane grid.See Fig. 3,4,7.Air inlet main section has two kinds of rectangle, circles, so the shell of apparatus of the present invention also has two kinds of rectangle and circle shapes accordingly.The fixed mesh of circular housing is circular, sees Fig. 2, a, b, c.When the air inlet main is pipe, when the shell of this device is pipe, the rotating vane grid connects square in being, sees Fig. 5.Its periphery has four airproof half curved baffles 21.Every slice graticule of rotating vane grid group 7 joins with the baffle plate 21 be connected, and baffle plate 21 and shell 2 inwalls join (seeing Fig. 5).Restriction fin open degree cross bar 19 be connected on spring 22, spring 22 is connected on spring vertical supporting 23, its underpart is supporting plate slideway 20.Supporting plate slideway 20 be connected with grid horizontal stripe 12, spring vertical supporting part 23 (seeing Fig. 6).

Above-mentioned these parts form rotating vane grid group 7 together.Link 16 goes up with each slice graticule most, the most lower fixing lined 12, spring vertical supporting part 23 upper and lower end are connected, and the rotating vane grid group is connected.

When motor moves in normal speed, above-mentioned two kinds of grid group can complete thin section mass transfer well, reach fuel-economizing and reduce the tail gas pollution effect.Motor car engine is when low cruise, because the flow of mist of oil and air is too low, while flowing through the fixed mesh group, flow velocity is low, the micro-vortex centrifugal inertia is too small, it is extremely insufficient that thin section mass transfer completes, fuel-economizing and reduction tail gas pollution successful variation, so the pollution maximum of orthodox car motor tail gas pollution maximum, particularly pm2.5 when low cruise.The rotating vane grid group above-mentioned situation of can greatly taking on a new look.When there is no mist of oil and Air Flow, cross bar 19 extruding that rotating vane 17 is promoted by spring 22, its open degree minimum, even when car speed is very low, also can guarantee the higher flowing velocity of the out-of-date generation of mist of oil and air stream, guarantees that thin section mass transfer can carry out well.Along with the raising of the speed of a motor vehicle, the pressure of mist of oil and air increases, and fin 17 is pushed and rotates backward, and fin grid open degree increases gradually, and when automobile reaches high speed, it is maximum that fin grid open degree also reaches.When variable open degree fin grid group can guarantee the automobile low-speed running, the thin section mass transfer of mist of oil and air, enter cylinder and fully burn, and increases substantially engine efficiency, significantly subdues the pollution of tail gas pollution, particularly pm2.5.

Working principle:

Spraying gasoline clean-burning precondition in cylinder is that each petrol molecule or micel will fully contact with airborne oxygen molecule.There are some researches show not burning of general-utility car fuel oil 1/3rd, slatterning in vain, its reason is that macroscopical mass transfer, thin section mass transfer are all insufficient, does not accomplish that each petrol molecule or micel fully contact with airborne oxygen molecule.The traditional theory people are divided into laminar mass transfer and turbulent mass transfer to mass transfer.Laminar mass transfer speed is extremely slow.The turbulent flow mass transfer rate is very fast, is that turbulent vortex induced effect causes.On Practical Project, at first the oil gas mass transfer is macroscopical mass transfer.Macroscopical mass transfer of science is within the extremely short time, to make mist of oil and air carry out rapidly, fully mix, and reaching at each macroscopical position oil gas is all uniformly, promotes the mist of oil gasification.Then carry out thin section mass transfer, oil gas and air carry out mass transfer at extremely contiguous position.For fuel engine, the difficulty of these two kinds of mass transfers is all very large.The basic skills that the present invention adopts be exactly in oil gas flows, manufacture turbulent, and quantity and the size of control vortex, petrol molecule is contacted with oxygen molecule more fully better.

At first, because very short to entering cylinder time from oil nozzle, if do not adopt science mass transfer means, macroscopical mass transfer is difficult to fully complete, and a lot of mist of oils can not fully contact with air.The macroscopic view mass transfer can be realized by following method.The nozzle of gasoline 4 is aimed to the center (see Fig. 14 and 5) of conical surface diffusion discs (or disk diffusion disc) 6, the mist of oil after spraying flows from center along diffusion disc 6 to periphery, the mist of oil layer of formation thin layer.Because of the pulsation perpendicular to the wall direction of the restriction mist of oil of diffusion disc 6 walls, its fluidised form is similar to laminar flow, with outer field air stream, blending does not occur substantially.When reaching the edge of diffusion disc, mist of oil and air stream and diffusion disc 6 lift-offs, and produce a series of vortexs along the periphery of diffusion disc 6, it after diffusion disc, is a vortex district, induced effect due to vortex, mist of oil and air have completed rapidly macroscopical mass transfer, and the concentration of all its mist of oils of macroscopical position and air is uniform substantially.

Thin section mass transfer is the mass transfer at extremely contiguous position.In turbulent motion, the fluidised form of extremely contiguous point-to-point transmission is laminar flow, so its mass transfer rate is extremely low, the mass transfer difficulty is very big.And in fluid, the centrifugal inertia of small vortex can strengthen the speed difference that mist of oil and air radially produce along vortex greatly, greatly improved the exposure rate of mist of oil and air.Allow mist of oil and air stream through multi-layer net, the both sides at glazing bar when fluid flows through lattice bar produce a series of little vortex.Two little vortexs converge the more less vortexs of generation, the eddy size that these less vortexs converge generation again is less, vortex is more, therefore all produce a high proportion of micro-vortex after every slice graticule, their centrifugal inertia has strengthened mist of oil and the thin section of air mass transfer rate widely, complete rapidly thin section mass transfer, make each molecule of mist of oil or micel can be fully with oxygen molecule, mix and contact, fully burn after entering cylinder.This can not only save oily consumption in a large number, more can significantly reduce the pollution of tail gas pollution, particularly pm2.5.
