Description
Technical field
The present invention relates to technical field of engines, in particular to a kind of EGR mixer.
Background technique
The mixing uniformity of fresh air and EGR exhaust (Exhaust Gas Recirculation, i.e. exhaust gas are recycled)
There is significant impact to the dynamic property, economy and emission performance of diesel engine.In the intake process of engine, if mixed
Clutch distribution is uneven, and the air-fuel mixture amount for being assigned to each cylinder through air inlet pipe is inconsistent, necessarily leads to the work one of each cylinder of engine
Cause property is poor, and combustion efficiency is bad；In addition, the restriction loss of EGR line directly affects each component accounting of gaseous mixture, and then influence
The combustion efficiency and pollutant emission of each cylinder interior of engine, in the intake process of engine, if the throttling of EGR line is damaged
It loses excessive, will lead to the reduction of EGR, and then lead to the increase of oxynitrides in emission.
Currently, the structure type of EGR mixer is more, for example, the patent application of Patent No. CN201310274335.8
In disclose in EGR mixer be arranged spoiler improve EGR gas and fresh air mixed effect；Patent No.
It is disclosed in the patent application of CN201110223772.8 and turbulent improvement is set at EGR mixer ontology and mixer adapter tube
The mixed effect of EGR gas and fresh air.Although the setting of spoiler and turbulent can be effectively improved EGR gas
With the mixed effect of fresh air, the uniformity of each cylinder air inlet of engine is improved, but its structure is relatively complicated, in engine
When high revolving speed, EGR line is be easy to cause to generate biggish restriction loss.
Therefore, how to meet engine be able to achieve under different rotating speeds EGR gas with fresh air is good mixes effect
While fruit, moreover it is possible to have both the technical issues of lower EGR line restriction loss is those skilled in the art's urgent need to resolve.
Summary of the invention
In view of this, can satisfy engine under different rotating speeds the purpose of the present invention is to provide a kind of EGR mixer
While being able to achieve EGR gas and fresh air good mixed effect, moreover it is possible to have both lower EGR line restriction loss.
To achieve the above object, the invention provides the following technical scheme:
A kind of EGR mixer, for being set to the inner cavity of FAI Fresh Air Intake pipeline, comprising:
Fastening sleeve is offered for being connected to extraneous exhaust outlet；
The first end of the fastening sleeve is inserted into EGR air inlet pipe, one end, and the other end stretches out the FAI Fresh Air Intake pipeline
Inner cavity, and for EGR gas enter；
Gas outlet is rotated, one end can be slidably inserted into the second end of the fastening sleeve, and the other end offers outer for being connected to
The gas vent on boundary；
Elastic component is set in the fastening sleeve, in the case where the elastic component is in reset state, the rotation gas outlet
The exhaust outlet is blocked completely, when the admission pressure of the EGR gas of the EGR air inlet pipe reaches threshold value, the rotation outlet
Cylinder overcomes the elastic component elastic force, moves to the direction reduced along the area for blocking the exhaust outlet.
Preferably, be provided with sliding bearing between the rotation gas outlet and the fastening sleeve, and the sliding bearing with
The rotation gas outlet is fixedly connected, and the sliding bearing is connected with fastening sleeve sliding.
Preferably, the sliding bearing includes bearing inner ring and outer race, in the rotation gas outlet and the bearing
Ring is fixedly linked.
Preferably, fin is provided on the outer race；Along the axis direction of the fastening sleeve be provided with for
The sliding slot of the fin clearance fit.
Preferably, the elastic component is spring, and the both ends of the spring are separately connected the EGR air inlet pipe and the axis
Hold outer ring.
Preferably, it is additionally provided with boss on the air inlet pipeline, plate is provided on the boss, is opened up on the plate
There is the through-hole passed through for the EGR air inlet pipe.
Preferably, gasket is additionally provided between the EGR air inlet pipe and the plate.
Preferably, the EGR air inlet pipe includes air inlet tube body and the connector that is set on the air inlet tube body, institute
It states fastening sleeve and the connector is connected.

It is good；When engine is in moderate rotation, air side flow velocity increases, and the admission pressure of EGR gas increases, when the air inlet of EGR gas
When pressure reaches threshold value, rotation gas outlet is moved along the direction that the area for blocking exhaust outlet reduces, when exhaust outlet is rotated out of
When the area that inflator blocks reduces, outflow in the exhaust outlet and gas vent that EGR gas can never be blocked is carried out with fresh air
Mixing, mixed effect are preferable；When engine is in higher rotation speed, air side flow velocity is further increased, EGR gas inlet pressure
Equally increase, when the admission pressure of EGR gas reaches threshold value, rotation gas outlet drives elastic component to continue direction and blocks exhaust outlet
The direction that reduces of area it is mobile, rotate gas outlet at this time and be staggered completely with exhaust outlet, EGR gas is most of from exhaust outlet row
Out, fraction is discharged from gas vent, is mixed with fresh air, has taken into account the restriction loss of mixed effect and EGR line.
It can be seen that the EGR mixer can satisfy engine is able to achieve EGR gas and fresh sky under different rotating speeds
While gas good mixed effect, moreover it is possible to have both lower EGR line restriction loss.
