To.Chinese Patent Application No.：CN201320541963.3 utility model discloses a kind of engine exhaust-gas recirculating system.Institute
Stating engine exhaust-gas recirculating system includes：Filter, is connected with the exhaust pipe of engine, the part discharged to the exhaust pipe of engine
Engine exhaust is filtered；Cooler for recycled exhaust gas, between the filter and engine air inlet tube, to through filtering
The engine exhaust of device filtering is cooled down；And air throttle, between the filter and engine air inlet tube, controlling stream
Exhaust gas flow through the filter.Gas recirculation system (Exhaust Gas Recirculation) abbreviation egr system,
It is to send the sub-fraction of waste gas of diesel engine or gasoline engine generation back to cylinder again；EGR gas with inertia due to that will prolong
Slow combustion process；That is burning velocity will slow down to cause the pressure initiation process in combustion chamber to slow down, here it is
Oxynitrides can reduction main cause；In addition, total exhaust gas flow (mass flow) can be made by improving ER EGR Rate
Reduce, therefore pollutant output quantity total in waste gas discharge relative will be reduced.Egr system is provided with the waste gas for producing engine
Sub-fraction send the flue gas leading of cylinder back to again；One end of flue gas leading is exhaust gas inlet, and the other end of flue gas leading is waste gas outlet；
There is waste gas outlet flow velocity comparatively fast in traditional flue gas leading, waste gas and the deficiency of fresh air undercompounding；Therefore, design a kind of
Waste gas outlet flow velocity is slower, and waste gas mixes the flue gas leading of sufficient egr system with fresh air, as urgent problem to be solved.
Utility model content
The purpose of this utility model be it is very fast in order to overcome current flue gas leading to there is waste gas outlet flow velocity, waste gas with it is fresh
Air undercompounding it is not enough there is provided a kind of waste gas outlet flow velocity is slower, waste gas mixes sufficient egr system with fresh air
Flue gas leading.

Include：The plugging plate being connected with the body other end；The gusset of the body other end is provided with venthole；The area of venthole is more than body
The cross-sectional area of endoporus.The venthole of the flue gas leading of the egr system is located at the gusset of the body other end, and the area of venthole
More than the cross-sectional area of the endoporus of body, flows decrease and air-flow is turned to during waste gas outflow venthole, increase waste gas with it is fresh
Air mixture time, makes waste gas be mixed fully with fresh air.
Preferably, described body includes：Head end enters gas section provided with first flange, and tail end is provided with the mistake of second flange
Linkage section is crossed, respectively with entering the union elbow 10 that gas section tail end and transition linkage section head end are connected, head end is provided with and second flange
The air outlet section of 3rd flange of connection；Venthole is located at air outlet section tail end gusset.The structure of body meets installation requirement and installation
It is convenient.
Preferably, described body also includes：Two mounting ears for being enclosed on outside transition linkage section；Mounting ear is provided with installation
Hole.The mounting ear being enclosed on outside transition linkage section can be fixed by moving axially and rotating regulation orientation beneficial to installing.
Preferably, described venthole is rectangular opening；The length direction of rectangular opening is identical with the axis direction of body.It is logical
Limitation outlet hole width body proof strength is crossed, increases the area of venthole by increased length.
Compared with prior art, the beneficial effects of the utility model are：The venthole of the flue gas leading of the egr system is located at pipe
The gusset of the body other end, and cross-sectional area of the area more than the endoporus of body of venthole, flow velocity during waste gas outflow venthole
Slow down and air-flow is turned to, increase waste gas and fresh air incorporation time make waste gas be mixed fully with fresh air.The structure of body
Meet installation requirement and easy for installation.The mounting ear being enclosed on outside transition linkage section can adjust orientation by moving axially and rotating,
Fixed beneficial to installing.Venthole is rectangular opening, and the length direction of rectangular opening is identical with the axis direction of body, by limiting outlet
Hole width body proof strength, increases the area of venthole by increased length.
