Abstract
The invention provides a fuel injection nozzle of an opposite-spraying atomizing internal combustion engine. On the basis of a traditional fuel injection nozzle, the original needle valve is changed to a cup-shaped tubular valve which is sleeved on a conical valve seat to control a plurality of oil injection holes on the valve seat. The bottom of the fuel injection nozzle and the valve seat are correspondingly provided with conical pits, the oil injection holes correspondingly arranged on the valve seat inject oil beams with the same horizontal included angle, a plurality of oil beams are oppositely impacted at the same potion, thus, the primarily atomized fuel particles are secondarily atomized. By using the fuel injection nozzle of the invention, the construction is simple, the manufacture is easy, and more excellent atomization effect can be obtained under the same oil injection pressure. The fuel injection nozzle is capable of replacing the traditional fuel injection nozzles and widely applied to the prior engines. The fuel injection nozzle can be made into the fuel injection nozzle of diesels or the fuel injection nozzle of gasoline engines and can be applied to the fuel injection nozzle of jet engines and mechanical equipment needing to atomize fuel.
Description
Affiliated field
The present invention relates to the design and the manufacturing technology of petrol engine fuel injection nozzle to the ejection type internal combustion engine fuel injection nozzle, and the design and the manufacturing technology of diesel engine fuel oil oil nozzle.Relate in particular to design and manufacturing technology to spray formula fuel-oil atmozation oil nozzle.
Background technique
Along with the progress of society, the energy consumption exhaust index of conventional engines can not satisfy modern society to the higher requirement of motor.Improve the quality of burning mixture, improving combustion condition is the important measures of energy-saving and emission-reduction.For pursuing higher atomization and optimized combustion effect, on diesel engine, begin to adopt high pressure common rail electric-controlled oil spout new technology, its fuel-injection pressure can be up to more than the 200Mpa.The development of high-pressure common rail technology is to realize with the injection pressure of superelevation.Injection pressure is big more, and then the oil spout energy is high more, oil spout is thin more, mixed gas forms and burning is complete more, thereby the emission performance of diesel engine and Economy all are improved.But the fuel pressure of superelevation not only needs high-quality oil-fired system, and also being needs to consume certain power consumption.
In order to improve the atomization quality of petrol engine mixed gas, on petrol engine, adopted electric jet technology widely.Along with country to improving constantly that motor car engine, energy-saving and emission-reduction require, how further to improve the fuel-oil atmozation quality, be most important in the engine art all the time.
Summary of the invention
The objective of the invention is, provide a kind of atomization formula fuel of internal combustion engine oil nozzle.The technological scheme of taking is: on the basis of traditional oil nozzle, the needle valve in the oil nozzle is made into as being inverted the pipe type valve of goblet shape.With the corresponding valve seat of pipe type valve, be a cone that makes progress, under coniform valve base, on the outer bottom of oil nozzle, establish corresponding with valve seat, as a to make progress pyramidal pits.Between coniform valve base and the columniform pit below it, ecto-entad is provided with several to, the nozzle opening that relatively sprays.Nozzle opening all sprays to inboard axial point, every pair of oil bundle that is sprayed is all intersected bump against to go up on one point.The horizontal angle of cut of every pair of oil beam jetted can be located between 20 °-45 °.The quantity of the nozzle opening on the nozzle can be determined according to dissimilar types, from 1-5 to all can.Under intensity and toughness allows, open a plurality of open-works on one's body at the cup of cup-shaped pipe valve, the quality that can reduce pipe valve can make the oil nozzle internal oil channel unobstructed again, can also adopt complete hollow tubular valve.In order to make spray orifice and tubular valve tight-closed, the bottom part of tubular valve is set as bottom less than 60 °, make it with the oil nozzle shell in 60 ° of grooves on base match, form sealing configuration.
The present invention is to atomization formula engine fuel oil nozzle, is to utilize in the nozzle opening oil bundle more than two of ejection at a high speed, collides relatively with certain angle.Utilize the kinetic energy of high-speed fuel oil bundle, make the collision relatively at a high speed of the fuel droplet that atomized, bump against, can divide countless littler droplets, therefore atomized fuel in high quality as the oil droplet of two different direction motions.Thisly the original spray angle of every oil bundle that is sprayed is changed, help spraying diffusion towards periphery, can under identical jet pressure, obtain better fuel-oil atmozation quality spray formula fuel-oil atmozation mode.
The present invention is on the basis of original oil nozzle, most of 26S Proteasome Structure and Function of the former oil nozzle of (comprising the electromagnetic coil part) reservation, its profile and the volume of oil nozzle, with traditional oil nozzle much at one, its principle is simple, easy to manufacture with low cost, can replace and be applied on the conventional diesel engine, and on the high pressure co-rail diesel machine.It is well suited for making the nozzle of petrol engine, is applied on the petrol engine.Importantly it can replace traditional oil nozzle easily, and the energy-conservation exhaust index of a large amount of orthodox cars is largely increased.Utilize fuel spray nozzle of the present invention, can also be applied on the air breathing engine, or other need in the equipment of fuel-oil atmozation.Therefore, its economic benefit that contains and social benefit are very huge.

Embodiment
Oil nozzle according to existing each diesel engine and petrol engine is the design reference foundation.Keep its normal structure and function, partly change needle valve into cup-shaped tubular valve, design the quantity and the aperture of spray orifice as requested.The installation dimension of newly-designed oil nozzle is consistent with former oil nozzle, or roughly the same.
