Abstract
The present invention relates to exhaust gas recycling system.The present invention relates to a kind of exhaust gas recycling system (1), since the bonding that pollution produces can be removed by intervening, wherein maintenance personnel is manually operated during vehicle maintenance, and it with least one axis (7), it is located at the other end of eccentric rod (6) and the residue on valve (2) is cleaned by way of being mechanically moved.
Description
Technical field
The present invention relates to exhaust gas recycling system, it is for reducing the most frequently used of discharged nitrous oxides in explosive motor
One of technology.
Background technology
Exhaust gas recirculatioon (EGR) is a kind of system, and the purpose is to pass through in-engine a part of exhaust gas recirculatioon
Be again introduced into cylinder be used for reduce due to the heat of burning generation, and control environmentally harmful oxides of nitrogen gas (NOx)。
It is widely used in current gasoline and diesel engine.
The mixture of fresh air and spent exhaust into engine reduces ignition temperature and reduces (diesel oil
In engine) excessive amount of oxygen.Due to NO at high temperaturexThe generation of gas accelerates, and control temperature also allows for control NOx
The generation of gas.
In egr system, a part of be vented produced after the burning carried out in the cylinder will not be discharged into air, but it
It can be circulated and be fed again into combustion chamber.In this manner, ignition temperature is by disturbing burning to be lowered, and nitrogen emissions
Generation be reduced.The gas flow circulated in egr system is adjusted using EGR valve according to engine calibration target.Lifting
Valve or butterfly valve can be used.In the system, by increasing the density of gas, enter to convey more gases
Combustion chamber, cooler for recycled exhaust gas are also used.When colder needed for vent ratio, water condensation in gas and by with also depositing
Combined in the coal ash in gas, the layer that pureed bonds is formed in EGR valve.The layer is by accumulating hardening, and passing through in time
It is dry to reach the degree for preventing that valve from opening and closing.In EGR valve, apply some technologies prevent by exhaust coal ash by with
Condensed water is with reference to the bonding for becoming pureed and producing.However, these technologies are excessively to eliminate it more on preventing from bonding.In order to prevent
Bonding, valve and valve seat, which are coated with, specially prevents cohesive material.In some implementations, when an engine is stopped, valve is intentional
Ground is kept it turned on.Using this mode, enable to bond the degree that is maintained at valve motor and can overcome by reducing bonding surface.
In this case, when the valve is in an open state, valve is stuck since pollution passes through bonding, since combustion chamber is filled
Exhaust and the reduction of oxygen level are expired, the problem of efficiency of combustion reduces, the idling mode and energy loss of interference can occur.
In this case, when the valve is in the closed position, valve is stuck since pollution passes through bonding, and nitrogen oxygen emission will increase.And
And the possibility of pinking will increase and engine timing interrupt possibility there will be.In this case, EGR valve because
Pollution is stuck due to being bonded in the position of opening or closing, and particularly electrically operated valve cannot be repaired, its needs is replaced.
American documentation literature US 2002144715, is well known in the art application, discloses a kind of for providing valve
The equipment moved again, it is intervened to clean EGR valve by using outside, any part without dismantling vehicle.This sets
Standby to include introducing device, it removedly may be mounted on the manifold of the engine of the position of EGR valve.Introducing device includes suitable
With disk and nozzle assembly.The equipment further comprises removedly may be mounted to the solvent manager on introducing device, for carrying
For a certain amount of solvent to egr system.
The content of the invention
It is an object of the invention to provide a kind of exhaust gas recycling system, wherein since the bonding that pollution produces can pass through
Intervention is removed, and is manually operated wherein intervening by maintenance personnel during vehicle maintenance.
It is another object of the present invention to provide a kind of exhaust gas recycling system, and when producing bonding, valve is not required in it
Repair or replace.
Brief description of the drawings
It is demonstrated in the accompanying drawings with the exhaust gas recycling system for meeting the object of the invention by developing, wherein：
Fig. 1 is the schematic diagram of the exhaust gas recycling system.
Component shown in figure is represented according to reference numeral given below：
1. exhaust gas recycling system
2. valve
3. valve shaft
4. frame
5. wheel
6. eccentric rod
7. axis.
Embodiment
Exhaust gas recycling system (1), wherein due to pollution produce bonding can by intervene be removed, wherein intervene by
Maintenance personnel is manually operated during vehicle maintenance, specifically includes：
- at least one valve (2),
- at least one valve shaft (3), is connected in its one end with valve (2), it preferably has cylinder,
- at least one frame (4), it is located at the other end of valve shaft (3),
- at least one wheel (5), it can be moved freely on the inside of the frame (4),
- at least one eccentric rod (6), wheel (5) are located at one end of eccentric rod (6),
- at least one axis (7), its be located at the other end of eccentric rod (6) and enable the residue on valve (2) pass through by
The mode of mechanical rotation is cleaned.
In one embodiment of the invention, in this case, when the valve (2) in exhaust gas recycling system (1)
When in an open position, since pollution is clung, combustion chamber declines valve (2) full of exhaust and oxygen level.In this case,
Efficiency of combustion reduces, and for example idling mode disturbs this problem to occur.Moreover, in this case, when valve is closed,
Valve is bonded since pollution becomes, the increase of nitrogen oxygen emission.This causes engine breakdown.In exhaust gas recycling system (1), its
It is developed to avoid these problems, one end that valve shaft (3) is present in valve (2) enables gas to pass through with definite flow.Valve
Axis (3) moves valve (2) and causes valve (2) to be fixed on preferable position.Frame (4) is installed on the another of valve shaft (3)
End.Frame (4) is preferably the shape of hollow rectangle prism.By the frame (4) with such shape, it is designed to make valve (2)
The wheel (5) moved up and down can be placed on wherein.Width due to taking turns (5) is less than the width of frame (4), and wheel (5) can hold
Change places and moved according to preferred orientations.Wheel (5) is located at one end of eccentric rod (6), and axis (7) is located at the other end.Take turns (5) and axis
(7) eccentric rod (6) is connected to by welding.Axis (7) positioned at eccentric rod (6) one end is dimensionally manufactured into can be by hand
Dynamic control, and axis (7) can be manually controlled.
The operation of exhaust gas recycling system (1) is achieved by the following procedure：The personnel of cleaning valve (2) hold axis (7) and cause
Axis (7) moves.In this manner, wheel (5) moves in frame (4).Wheel (5) moves valve shaft since it is connected to valve shaft (3)
Thus the mobile valve (2) of valve shaft (3) (3),.Valve (2) is moved with the speed of personnel's shifting axle (7).Given by the personnel
After axis (7) applying power is to perform these movements, valve (2) is mobile and the movement opens and closes valve (2).Pass through this mistake
Journey, the bonding that elimination can produce in valve (2).
