Description
Technical field
The utility model relates to a kind of internal combustion engine injection valves, and in particular to a kind of aeration type air injection valve.
Background technique
As the cry of global energy-saving and emission-reduction constantly increases, environmental requirement is discharged also increasingly to the exhaust gas of internal combustion engine by various countries
Height, thus also have harsher environmental requirement to the exhaust system of internal combustion engine.
Existing exhaust gas filtering system is mainly three-way catalytic apparatus, under the trend that discharge standard is continuously improved, ternary
Filter density in catalytic unit is increasing, so that it is not smooth enough so that exhaust is obstructed, exhaust gas cannot emit in time, newly
Thus there is the intracavitary fuel oil combustion of internal combustion engine because the obstruction by exhaust gas cannot properly enter combustion chamber in fresh mixed gas
Burn it is insufficient, cause internal combustion engine export power have the shortcomings that decaying by a relatively large margin, meanwhile, exhaust gas is in three-way catalytic apparatus
Manage not complete enough, there are still have the case where pollution when being discharged into outside environment.
Summary of the invention
Fuel burning is insufficient caused by the utility model is obstructed for air present in the prior art, power decaying
Problem and gas discharge polluted disadvantage, and provide a kind of aeration type air injection valve, it includes injection valve body, described
Injection valve body be a hollow tube body and at inner wall setting ratio position be equipped with the oblique protrusion of integrally formed double inclined plane,
The protrusion position is boss, and the space that the inclined-plane protrusion before the boss is formed is expansion hatch, and boss is subsequent tiltedly
The space that face protrusion is formed is boost port, and the injection valve body is equipped with oxygenation ring, and to be located at boss corresponding for oxygenation ring
On injection valve body outer wall, be equipped with air duct inside oxygenation ring, air duct is equipped with check valve, the air duct with
Vacuum tank connection, vacuum tank are located at the boss inner surface of injection valve body, and the extension line of vacuum tank and injection valve body hangs down
Directly.
Quantity is equipped with inside the oxygenation ring and is no less than 4 air ducts, and air duct is evenly distributed on oxygenation ring
It is interior.
The vacuum tank is annular shape.
The injection valve body and oxygenation ring are the C20 special steel material of ti coat on diamond.
The injection valve body is located at expansion hatch that side chamfer length greater than boost port that side chamfer length.
The injection valve body is mounted at the front end of three-way catalytic apparatus or the connecting port of rear end.
Utility model has the advantages that being then arranged inside oxygenation ring by the way that oxygenation ring is arranged outside injection valve
Air duct allows air duct to be to provide fresh air inside injection valve, these fresh airs can have with HC, CO etc. in exhaust gas
Evil gas reaction, makes it be further converted into CO2 and vapor, reduces exhaust pollution with this, and the internal structure meeting of injection valve
Make the gas in internal combustion engine quickly through three-way catalytic apparatus, and discharge resistance suffered in exhaust pipe, through the above arrangement
It can make this injection valve that there is the environment protecting of fuel-economizing, speed-raising.

Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
It is as Figure 1-Figure 2: a kind of aeration type air injection valve, wherein the inside of injection valve body 1 is convex equipped with double inclined plane
Then portion is generated " Venturi effect " using double inclined plane protrusion, is accelerated the discharge of exhaust gas with this, and Venturi effect " principle
It is when blowing air over obstacle, near ports air pressure is relatively low above the leeward of obstacle, to generate suction-operated
And lead to the flowing of air；And in this injection valve, when exhaust gas passes through boost port 4, the inclined-plane aperture at boost port 4 is continuous
Reduce, exhaust gas can be formed squeeze in this way, it is made to possess certain injection pressure, if the gas of engine exhaust is bigger, that
The pressure that gas is subject at boost port 4 also can be bigger, and the reaction force of injection can also increase with it, when the high temperature that these are pressurized
When gas is released at expansion hatch 5, these gases will generate physical expansion, and expansion will form powerful thrust and can be
A pull of vacuum is formed at boss 8, thrust can accelerate the flow velocity and dynamics of exhaust gas discharge, and discharge gas institute in exhaust pipe
The resistance being subject to keeps the exhaust effect of internal combustion engine faster more smooth than original, just can increase the mass rate of emission of exhaust gas in this way, then
Keep the fuel burning of fuel oil more abundant, improves the power output efficiency of internal combustion engine, and pull of vacuum can open check valve 6, so
The fresh air inspiration of outside is sprayed inside valve body 1 by air duct 3 afterwards, check valve 6 can guarantee that these air will not
Reflux will not flow to outside out of air duct 3, will be in high temperature item when then these ozones enter inside injection valve
Oxidation reaction occurs with pernicious gases such as HC, CO in exhaust gas under part, so that it is further converted into CO2 and vapor, is subtracted with this
The pollution of few exhaust gas discharge, and 4 air ducts 3 are equipped in oxygenation ring 2, fresh air can in this way entered from multiple channels,
Guarantee that the pernicious gas in exhaust gas is sufficiently reacted with fresh air, farthest reduce pollution, and sprays valve body and oxygenation
Ring is made of the C2O special steel material of ti coat on diamond, this can guarantee, and this utility model is big with hardness, energy is resistant to high temperature excellent
Point.
Just the exhaust gas of internal combustion engine can be made quickly through three-element catalytic through the above arrangement, and discharged in exhaust pipe suffered
Pressure reaches the environment protecting of fuel-economizing, speed-raising with this to make fuel burning more abundant, and reduces pernicious gas in exhaust gas
Discharge reduces pollution.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, those skilled in the art should understand that, based on the technical solution of the present invention, ability
Field technique personnel do not need to make the creative labor the various modifications or changes that can be made still in the protection model of the utility model
Within enclosing.
