Description

Fuel engines efficient mass transfer device

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

The present invention is oil gas efficient mass transfer device. Its effect is that the mist of oil after making spraying is sufficiently mixed with air rapidly efficiently, enters cylinder and fully burns, increases substantially engine efficiency, significantly cut down the pollution of tail gas pollution, particularly pm2.5.

Operation principle:

Spraying gasoline clean-burning prerequisite in the cylinder is each petrol molecule or micel will be fully contacted with the oxygen molecule in air. There are some researches show general-utility car fuel oil 1/3rd not burning, slatterning in vain, its reason is that macroscopic view mass transfer, thin portion mass transfer are all insufficient, it does not have accomplish that each petrol molecule or micel are fully contacted with the oxygen molecule in air. Traditional theory people are divided into laminar mass transfer and turbulent flow mass transfer mass transfer. Laminar mass transfer speed is extremely slow. Turbulent flow mass transfer rate quickly, is that the vortex induced effect of turbulent flow causes. On Practical Project, first oil gas mass transfer is macroscopic view mass transfer. Macroscopical mass transfer of science is to make mist of oil and air carry out rapidly, be sufficiently mixed within the extremely short time, and it is all uniform for reaching at each macroscopic view position oil gas, promotes mist of oil gasification. Then carrying out thin portion mass transfer, namely oil gas carries out mass transfer with air at extremely contiguous position. It is all very big for the difficulty of both mass transfers fuel engines. The basic skills that the present invention adopts is exactly at gas stream disorder of internal organs manufacture turbulent flow, and controls quantity and the size of vortex, makes petrol molecule contact more abundant with oxygen molecule more good.

Firstly, because very short from oil burner nozzle to entering cylinder time, if not adopting science mass transfer means, macroscopic view mass transfer is difficult to be sufficiently complete, and a lot of mist of oils can not be fully contacted with air. Macroscopic view mass transfer can realize by method the following. The nozzle 4 of gasoline is directed at taper seat diffusion disc (or disk diffusion disc) 6 center (see Fig. 1,4 and 5), the mist of oil after spraying from centrally along diffusion disc 6 to perimeter, form the mist of oil layer of thin layer. Because the restriction mist of oil of diffusion disc 6 wall is perpendicular to the pulsation in wall direction, its fluidised form is similar to laminar flow, does not substantially blend with the air stream of outer layer. When reaching the edge of diffusion disc, mist of oil and air stream and diffusion disc 6 lift-off, and along diffusion disc 6 periphery produce a series of vortexs, it it is a vortex district after diffusion disc, induced effect due to vortex, mist of oil and air have been quickly completed macroscopical mass transfer, and namely its mist of oil of all of macroscopic view position is substantially with the concentration of air uniformly.

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 greatly increase the speed difference that mist of oil radially produces along vortex with air in fluid, substantially increase the exposure rate of mist of oil and air. Allow mist of oil and air flow through multi-layer net, when fluid flows through lattice bar, produce a series of little vortex in the both sides of glazing bar. 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 after every grid, all produce a high proportion of micro-vortex, their centrifugal inertia greatly increases mist of oil and air thin portion mass transfer rate, it is quickly completed thin portion mass transfer, makes each molecule of mist of oil or micel fully to contact with oxygen molecule mixing, fully burn after entering cylinder. This can not only save the consumption of oil in a large number, and the pollution of tail gas pollution, particularly pm2.5 more can be greatly reduced.

Implementation:

This fuel engines efficient mass transfer device is mounted between electromotor supply 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, taper seat diffusion disc (or circle flat board diffusion disc) 6, grid group 7, differential pressure flow sensor 8, temperature sensor 9. Thereafter 10 is air intake branch of the engine, and 11 is fuel engines. See Fig. 1. Orifice plate air flow sensor 2, differential pressure flow sensor 8, temperature sensor 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 the multi-layer net composition of rectangle, polygon or circle. See Fig. 2. Moving mesh group is the regulatable grid group of barrel hole size, and its driving mechanism can be different with the structure of oil circuit versatile and flexible with application engine. The first of the present invention releases rotating blade grid group, and the grid variable by multi-disc aperture and auxiliary device thereof form. Every grid is that many fixing lined bar 12 connectors 13 connect into entirety. A plurality of rotating shaft 14 by be fixed on grid go up most, under top cover 15 on lined bar 12 back side support fixing. Fin 17 side is connected in rotating shaft 14, and opposite side has multiple little wing 18 vertical with fin 17, constitutes rotating blade grid. See Fig. 3,4,7. Air inlet main section has rectangle, circle two kinds, and therefore the shell of apparatus of the present invention also has rectangle and circular two kinds accordingly. The fixed mesh of circular housing is circular, sees Fig. 2, a, b, c. Connect square in rotating blade grid circular housing, see Fig. 5. Its periphery has four airproof half curved baffles 21. Every grid of rotating blade grid group 7 connects with the baffle plate 21 being connected, and baffle plate 21 connects (see Fig. 5) with shell 2 inwall. Restriction fin open degree cross bar 19 connect on the springs 22, spring 22 is connected on spring vertical supporting 23, and its underpart is pallet runners 20. Pallet runners 20 is connected (see Fig. 6) with grid horizontal stripe 12, spring vertical support piece 23.

These parts above-mentioned constitute rotating blade grid group 7 together. Connector 16 is gone up with each grid most, the most lower fixing lined bar 12, spring vertical support piece 23 upper and lower side are connected, and rotating blade grid group is connected.

When electromotor is in normal speed operation, above two grid group can complete thin portion mass transfer well, reaches fuel-economizing and reduces tail gas pollution effect.Automobile engine is when low cruise, owing to the flow of mist of oil Yu air is too low, flow through flow velocity during fixed mesh group 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 effect are substantially deteriorated, and therefore orthodox car electromotor tail gas pollution when low cruise is maximum, and particularly the pollution of pm2.5 is maximum. Rotating blade grid group then can be taken on a new look above-mentioned situation significantly. When not having mist of oil and air flowing, the cross bar 19 that rotating blade 17 is promoted by spring 22 extrudes, and its open degree is minimum, even if car speed is very low, also can guarantee that and produces higher flowing velocity when mist of oil and air flow through, it is ensured that thin portion mass transfer can be well carried out. Along with the pressure of the raising of speed, mist of oil and air increases, fin 17 is rotated backward by promotion, and fin grid open degree is gradually increased, and when automobile reaches most high speed, fin grid open degree also reaches maximum. Variable open degree fin grid group can guarantee that mist of oil and the thin portion mass transfer of air during automobile low-speed running, enters cylinder and fully burns, increases substantially engine efficiency, significantly cut down the pollution of tail gas pollution, particularly pm2.5.

The feature of apparatus of the present invention:

Oil burner nozzle 5 is positioned at the center of this crust of the device 2 (extending supply main), the center of positive alignment taper seat diffusion disc or circle flat board diffusion disc 6, sets 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 the grid composition of rectangle, polygon or circle; 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 change of electromotor and oil channel structures, is all be automatically adjusted by the promotion of gas stream.
