Description
Technical field
The utility model relates to vehicle maintenance service more particularly to a kind of inlet exhaust gas guiding devices.
Background technique
Traditional motor vehicle exhaust emission is that tail gas is directly discharged into air by tailpipe, since tail gas was discharging
It is interfered in journey by from flows outside air, forms damping in exhaust pipe mouth, it is useless to slow down automobile engine hybrid combustor
Gas mass rate of emission reduces engine from the combined amount of external sucking air, and incomplete combustion will produce fuel oil in the combustion chamber
Raw carbon monoxide and carbon distribution, not only waste fuel oil, and polluted air.
Utility model content
It is several using deflector the purpose of the utility model is to provide a kind of reasonable in design, easy for installation, at low cost
Opening disperses the gas of entrance, reduces noise, while carrying out absorbing exhaust particulate object, the row of reduction using multilayer diversion pipe
Put the inlet exhaust gas guiding device of pollution.
Purpose of the utility model is realized as follows: a kind of inlet exhaust gas guiding device, including shell, setting are in shell
Interior deflector, the shell include three-decker, are made of top diversion pipe a, diversion pipe b and diversion pipe c, the water conservancy diversion
Middle position deflector is set in pipe a, and the deflector is circular configuration, is inside that vertically and transverse baffle these friendships are arranged
It pitches baffle and constitutes several square apertures, trapezoidal orifice plate is equipped in each opening, the orifice plate orientation is different；It is described to lead
Cylindricality cellular board is arranged in center in flow tube b and diversion pipe c.
As the further preferred scheme of the utility model, pass through between the diversion pipe a, diversion pipe b and diversion pipe c
Bolt is fixedly connected and sealing structure is arranged between diversion pipe contact surface.
As the further preferred scheme of the utility model, conduction pipe is arranged in the upper end the diversion pipe a.
As the further preferred scheme of the utility model, the orifice plate be it is trapezoidal, long side is fixedly connected on rectangular open
Mouth is on one side and orifice plate is obliquely installed with opening.
As the further preferred scheme of the utility model, one is connected to by welding manner between the baffle and baffle
It rises.
It is identical with a line square aperture inner hole board placing as the further preferred scheme of the utility model.
As the further preferred scheme of the utility model, same row square aperture inner hole plate placing direction is staggered.
As the further preferred scheme of the utility model, the diversion pipe b and the interior cylindricality cellular board being arranged of diversion pipe c
Hole diameter is different.
Compared with prior art, the utility model has the advantage that as follows: the utility model structure is simple, cost compared with
It is low, air-flow is scatter by the way that orifice plate is arranged in several openings, improves the mixability of motor exhaust and ammonia, and then increase
Conversion ratio avoids the leakage of ammonia；Since orifice plate is inclined in opening, so can effectively avoid at low temperatures
Liquid large impact is hit on water conservancy diversion inside pipe wall, and has certain flow-disturbing to act in air-flow.
Detailed description of the invention
It, below will be in embodiment technical description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Required attached drawing does simple introduction, it should be apparent that, the accompanying drawings in the following description is only the one of the utility model

Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are not under the premise of making creativity labour
All other embodiment obtained, belongs to the range of the protection of the utility model.
As shown in Figure 1-3, a kind of inlet exhaust gas guiding device, including shell 1, setting are in the intracorporal deflector 2 of shell, described
Shell 1 includes three-decker, is made of top diversion pipe a3, diversion pipe b4 and diversion pipe c5, setting in the diversion pipe a3
Middle position deflector 2, the deflector 2 are circular configuration, are inside to be arranged vertically with transverse baffle 9, these intersect baffle
Several square apertures 7 are constituted, trapezoidal orifice plate 8 is equipped in each opening 7,8 orientation of orifice plate is different；The water conservancy diversion
Cylindricality cellular board 10 is arranged in center in pipe b4 and diversion pipe c5.
Preferably, it is bolted to connection between the diversion pipe a3, diversion pipe b4 and diversion pipe c5 and in water conservancy diversion
Sealing structure is set between pipe contact surface.
Preferably, conduction pipe 6 is arranged in the upper end the diversion pipe a3.
Preferably, the orifice plate 8 is trapezoidal, and long side is fixedly connected on square aperture 7 on one side and orifice plate 8 inclines with opening 7
Tiltedly setting.
Preferably, it is linked together between the baffle and baffle by welding manner.
