Wheel engine with supercharger has obtained extensive utilization so that engine exhaust side structure is more complicated.Turbocharged engine is come
Say, it is easier to the problem that air inlet end cone fracture occurs.Reason is as follows: 1. row's temperature is high, and the thermal stress born is excessive；2. in order to full
Foot discharge standard, large-duty engine catalyst converter carrier bulk increases, and weight is relatively big, the weight that catalyst converter air inlet end cone is born
Greatly；3. the oscillation intensity of turbocharged engine itself such as is better than at the discharge capacity naturally aspirated engine.Therefore, turbocharged engine
There is the risk of air inlet end cone fracture in the catalyst converter of machine.Additionally, for using turbo charged electromotor, installation site is more
Being limited by space, electromotor has strict requirements along the position in length of wagon direction, in addition gas extraction system periphery have other zero
Parts exist, and cause having what difficult sealing was easily leaked gas between ternary catalytic converter assembly and turbo-charger complement mounting flange
Problem.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of ternary catalytic converter assembly, to solve the increasing of existing turbine
The problem that the ternary catalyzing unit of hydraulic motor is always easily caused air inlet end cone fracture.
The technical scheme that this utility model solution technical problem is used is: this ternary catalytic converter assembly is provided with in including

The involutory welding of air inlet pipe II half-shell is constituted, and described air inlet pipe is provided with multiple mounting bracket in two half-shell junctions；In described air inlet
End cap and described cylinder are externally provided with heat shield, are provided with multiple groove at the described heat insulation outer surface covering in described cylinder section.
In above-mentioned ternary catalytic converter assembly, more specifically technical scheme is it may also is that at least divide at described inlet flange
It is furnished with three pilot holes；Described flange of giving vent to anger is provided with heat-insulating bracket.
Further: described air inlet end cap has air inlet inner end cap and the air inlet outer end being located at outside described air inlet inner end cap
Lid.
Owing to have employed technique scheme, this utility model compared with prior art has the advantages that 1, enters
Trachea is welded by two stamping forming half-shell are involutory, enhances the strength and stiffness of air inlet pipe；And the two of air inlet pipe
Half-shell junction is provided with multiple heat shield mounting bracket, and two stands two ends are separately positioned under air inlet pipe upper half shell 3 and air inlet pipe
In half-shell 2, air inlet pipe so can be made to be more firmly mounted, alleviate the inlet flange of catalyst converter and weight that air inlet pipe is born
Amount, and then ensure that catalyst converter is fixing firm, not easy fracture, the phenomenon that air inlet end cone ruptures will not occur；Make again basis three simultaneously
The frequency of vibration of unit's catalytic converter assembly entirety keeps consistent with amplitude, improves the mode of whole ternary catalytic converter assembly, improves
The reliability of product；2, three pilot holes are distributed on inlet flange 1, can effectively increase both sealing areas, shorten two
Sealed width between individual fastening point, efficiently solves the difficult sealing of ternary catalytic converter assembly and turbo-charger complement junction
The easily problem of gas leakage；3, it is externally provided with heat shield, by blocking-up and the guide functions of heat shield at air inlet end cap and described cylinder
The heat that ternary catalyzing unit is radiated and thermal current isolation and dredge, can the transmission of effective intercept heat, reduction periphery
Parts temperature.Meanwhile, be provided with multiple groove at the heat insulation outer surface covering in cylinder section, these grooves not only can be greatly improved every
The ability of anti-deformation that is heated of heat cover, and its heat insulation area can also be expanded so that it is outsourcing effective to catalyst assembly can be formed
Wrap up in, solve the foreign material such as cylinder upper mud easy to stick and the problem that affects catalytic effect and service life.
