The beneficial effect that the utility model has:
The utility model can manufacture turbulent flow in oil gas flowing, and controls quantity and the size of vortex, petrol molecule is contacted with oxygen molecule more abundant better.
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 fully can not contact with air.Macroscopic view mass transfer can realize by method the following.By the center of the nozzle alignment conical surface diffusion disc (or disk diffusion disc) of gasoline, the mist of oil after spraying, from center along diffusion disc to perimeter, forms the mist of oil layer of thin layer.Because the restriction mist of oil of diffusion disc wall is perpendicular to the pulsation in wall direction, its fluidised form is similar to laminar flow, substantially blending does not occur with outer field air stream.When reaching the edge of diffusion disc, mist of oil and air stream and diffusion disc lift-off, and produce a series of vortex along the periphery of diffusion disc, it is a vortex district after diffusion disc, due to the induced effect of vortex, mist of oil and air complete rapidly macroscopical mass transfer, and namely all its mist of oils of macroscopical position and the concentration of air are 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 increase the speed difference that mist of oil and air produce along vortex radial direction greatly 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 is again less, vortex is more, therefore after every slice graticule, a high proportion of micro-vortex is all produced, their centrifugal inertia increases mist of oil and air thin portion mass transfer rate widely, complete rapidly thin portion mass transfer, each molecule of mist of oil or micel fully can be mixed with oxygen molecule and contact, enter Thorough combustion after cylinder.This can not only save the consumption of oil in a large number, more significantly can reduce tail gas pollution, particularly the pollution of pm2.5.
