Description

Fuel engine efficient mass transfer device

Technical field: a kind of novel fuel motor mass transfer apparatus.

The present invention is oil gas efficient mass transfer device.Its effect is that the mist of oil after spraying is fully mixed with air rapidly efficiently, enters cylinder and fully burns, 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 portion mass transfer are all insufficient, does not accomplish that each petrol molecule or micel fully contact with airborne oxygen molecule.Traditional theory people are divided into laminar mass transfer and turbulent mass transfer mass transfer.Laminar mass transfer speed is extremely slow.Turbulent flow mass transfer rate is very fast, is that turbulent vortex induced effect causes.On Practical Project, first oil gas mass transfer is macroscopical mass transfer.Macroscopical mass transfer of science is within the extremely short time, to make mist of oil carry out rapidly, fully mix with air, and reaching at each macroscopical position oil gas is all uniformly, promotes mist of oil gasification.Then carry out thin portion 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 is exactly in oil gas flows, to manufacture turbulent flow, and controls quantity and the size of vortex, makes petrol molecule contact more fully better with oxygen molecule.

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.Macroscopic view mass transfer can be realized by method below.The center (see Fig. 1,4 and 5) of the nozzle of gasoline 4 being aimed to conical surface diffusion disc (or disk diffusion disc) 6, the mist of oil after spraying flows from center along diffusion disc 6 to periphery, forms the mist of oil layer of thin layer.Because the restriction mist of oil of diffusion disc 6 walls is perpendicular to the pulsation of wall direction, its fluidised form is similar to laminar flow, with outer field air stream, blending does not occur substantially.In the time 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, due to the induced effect of 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 portion 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, mass transfer difficulty is very big.And the centrifugal inertia of small vortex can strengthen the speed difference that mist of oil and air radially produce along vortex greatly in fluid, greatly improve 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 is again less, vortex is more, therefore after every slice graticule, all produce a high proportion of micro-vortex, their centrifugal inertia has strengthened mist of oil and the thin portion of air mass transfer rate widely, complete rapidly thin portion mass transfer, make each molecule of mist of oil or micel can be fully mix and contact with oxygen molecule, 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.

Implementation methods:

This fuel engine efficient mass transfer device is mounted between motor air feed main and cylinder.This device is made up of interface bolt 1, shell 2, annular oriffice 3, frequency conversion air pump air supply pipe entrance 4, fuel nozzle 5, conical surface diffusion disc (or the dull and stereotyped diffusion disc of circle) 6, 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.See Fig. 1.Orifice plate air flow sensor 2, differential pressure flow sensor 8, temperature transducer 9 are all connected with electronic control unit (ECU).7 points of fixed mesh groups of grid group and two kinds of structures of moving mesh group.Fixed mesh group is constant by barrel hole size, is shaped as rectangle, polygonal or circular multi-layer net composition.See Fig. 2.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, is made up of the variable grid of multi-disc aperture and accessory thereof.Every slice graticule is that many fixing lined 12 use links 13 connect into entirety.Grid is gone up most by being fixed on for many rotating shafts 14, 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 multiple winglet wings 18 vertical with fin 17, form rotating vane grid.See Fig. 3,4,7.Air inlet main section has two kinds of rectangle, circles, and therefore 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.In rotating vane grid circular housing, connect square, see 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 being 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 rotating vane grid group is connected.

When motor moves in normal speed, above-mentioned two kinds of grid group can complete thin portion mass transfer well, reach fuel-economizing and reduce tail gas pollution effect.Motor car engine is in the time of low cruise, because the flow of mist of oil and air is too low, while flowing through fixed mesh group, flow velocity is low, micro-vortex centrifugal inertia is too small, it is extremely insufficient that thin portion mass transfer completes, fuel-economizing and reduction tail gas pollution successful variation, the therefore pollution maximum of orthodox car motor tail gas pollution maximum, particularly pm2.5 in the time of low cruise.The rotating vane grid group above-mentioned situation of can greatly taking on a new look.In the time there is no mist of oil and Air Flow, the cross bar 19 that rotating vane 17 is promoted by spring 22 pushes, and 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 portion 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 in the time that automobile reaches high speed, it is maximum that fin grid open degree also reaches.When variable open degree fin grid group can guarantee automobile low-speed running, the thin portion mass transfer of mist of oil and air, enters cylinder and fully burns, and increases substantially engine efficiency, significantly subdues the pollution of tail gas pollution, particularly pm2.5.

The feature of apparatus of the present invention:

Oil nozzle 5 is positioned at the center of this crust of the device 2 (extending air feed main), and the center of positive alignment conical surface diffusion disc or the dull and stereotyped diffusion disc 6 of circle, establishes thereafter grid group 7.

Grid group 7 has two kinds of forms, the fixing fixed mesh group of first barrel hole size, is shaped as rectangle, polygonal or circular grid composition; It two is that barrel hole size is self-adjustable.The drive mechanism of eyelet (grid) size adjustment can be versatile and flexible because of the variation of motor and oil channel structures, is all automatically to be regulated by the promotion of gas stream.

The inventive example goes out multi-disc by the variable rotating vane grid group of rotating vane 17 and the orthogonal open degree forming of fixing glazing bar 12.
