Description
Technical field
The utility model relates to turbosupercharged engine, is specifically related to a kind of turbosupercharged engine ternary catalytic converter assembly structure.
Background technique
For adopting turbo charged motor, generally its vent systems is comprised of component such as cast-iron exhaust manifold, turbo-charger complement, ternary catalytic converter assemblies.At the design aspect of the Placement of turbo-charger complement and ternary catalytic converter assembly, the structural type that usually adopts three hole flange plate to connect.Owing to being subject to cabin space, limit, the motor X-direction is (for car to speech, the length direction that X-direction is car) distance has stricter requirement, the vent systems periphery has front end wheel train in addition, air condition compressor, the component such as generator exist, what cause ternary catalytic converter assembly and turbo-charger complement mounting flange not to design is too large, be easy to like this cause ternary catalytic converter assembly and turbo-charger complement mounting flange to leak gas because sealing strip is too narrow, or can't use pneumatic tool to carry out quick mounting, can only adopt manual mode fastening, affect the manufacturing efficiency of motor, thereby waste resource.
Chinese patent document CN203009016U discloses a kind of ternary catalystic device structure of turbosupercharged engine, the stainless steel suction tude that its typical structure is the S type and the inlet flange dish in three holes, but, for the assembling that meets the inlet flange dish and the arrangement space of catalyst converter, the shape of S type Stainless Steel Tube is more complicated and length is longer.
Summary of the invention
The utility model is arranged and the assembling problem for the sealing, the space that solve between turbo-charger complement and ternary catalytic converter assembly, proposes a kind of supercharged engine ternary catalytic converter assembly structure, increases sealing area, optimizes space and arranges, improves assembling.
For solving the problems of the technologies described above, the utility model is taked following technological scheme:
A kind of supercharged engine ternary catalytic converter assembly, comprise the suction flange dish, air inlet end cone, the housing that connect successively, outlet end cone, steam outlet pipe and outlet(discharge) flange dish.Be distributed with four pilot holes on described suction flange dish, wherein two holes of a side are the semi-open type hole, and two holes of opposite side are positioning round orifice.
Further, the cross section of air inlet end cone is oval, and two positioning holes of described suction flange dish and the position in two semi-open type holes are respectively in oval major axis both sides, and their shaft axis is all outside the outer wall of air inlet end cone.
Further, described suction flange dish card perpendicular to the plane at the place, joint of air inlet end cone and housing.
Further, air inlet end cone is divided into upper half shell and lower half shell along oval minor axis, and two-part impact briquetting butt welding connect.
Further, two reinforcing brackets are arranged on described housing, wherein interior reinforcing bracket is welded on the housing of catalyst converter, and form one end that outer reinforcement support is bolted is connected with interior reinforcing bracket, and the other end is for fixing with engine cylinder-body.
From above structure, this catalyst converter has adopted four pilot holes at the suction flange dish, choose two and do the open type design, other two holes are as positioning hole, increase like this pilot hole number, effectively increase both sealing areas, shorten two sealed widths between fastening point, efficiently solve the gas leakage risk of ternary catalytic converter assembly and turbo-charger complement joint.And the design in semi-open type hole, purpose is the adjustment while facilitating bolts assemblies.Simultaneously air inlet end cone, according to the shape of flange plate, is optimized to ellipse, can make thus the air flue outer wall of major axis both sides not block pilot hole, and it is fastening that purpose facilitates pneumatic tool to carry out quick mounting exactly.And the two half shell welded structures of air inlet end cone employing, air inlet runner is shorter, and thermal loss is less, and the ignition of catalyzer is more favourable.Simultaneously, due to the spatial position of having adjusted flange plate and air inlet end cone, adopt subvertical direction, four pilot holes of inlet flange dish are had living space fully adopt universal pneumatic tool to operate fastening, realize fast pipeline production.In addition, be designed with two reinforcing brackets at the middle part of catalyst converter, so can improve the mode of whole ternary catalytic converter assembly, giving in to each other property in the time of can guaranteeing mount support again, eliminate assembly error.
