Abstract
The utility model relates to a three-way catalytic converter which comprises a front connecting flange, an air inlet pipe, an upper end cover, a lower end cover, a liner, a catalyst, an air exhaust pipe and a rear connecting flange, wherein the catalyst is in an elliptic cylinder shape; the liner is wrapped on the outer side of the periphery of the catalyst; the upper end cover and the lower end cover are semi-shell housings with semielliptic middle cross sections, two closed ends and semicircular cross sections; the catalyst wrapped with the liner is assembled in a cavity formed by the buckling of the upper end cover and the lower end cover to form a catalytic converter assembly; one end of the air inlet pipe and one end of the air exhaust pipe are assembled on two sides of the catalytic converter assembly respectively; the front connecting flange is mounted at the other end of the air inlet pipe; and the rear connecting flange is mounted at the other end of the air exhaust pipe. As the catalytic converter adopts the elliptic cavity, a space is saved, a three-way catalysis effect is achieved, and a purifier formed by stamping is connected with the front connecting flange at the front end in a welding manner.
Description
Technical field
The utility model relates to a kind of ternary catalyzing unit, belongs to technical field of engines.
Background technique
Ternary catalyzing unit mainly is that the harmful gases such as CO, the HC of imperfect combustion generation discharge and NOx are pooled to the ternary catalyzing unit reaction by purifier, and oxidation and reduction change harmless carbon dioxide, water and nitrogen into, satisfy emission request.Present three-way catalyst mainly wraps up and is placed in the metal shell with liner, and guarantee that catalyzer is unlikely to burst when being subject to the outside unexpected cooling of car body, but the ternary catalyzing unit housing of most is circular, because of the space that car domain catalyst converter is put less, if adopt round carrier just can't place.So adopt half-shell racetrack carrier package mode, can solve so the little and difficulty that can't put carrier in space, chassis.
Summary of the invention
The model utility purpose: the purpose of this utility model is for the deficiencies in the prior art, and a kind of ternary catalyzing unit is provided, and takies the ground disk space less, is convenient to be installed on various types of chassis.
Ternary catalyzing unit of the present utility model comprises front adpting flange, suction tude, upper end cap, lower end cap, liner, catalyzer, outlet pipe, rear adpting flange; Catalyzer is elliptical cylinder-shape, liner is wrapped in the catalyzer periphery, it is that close up in half elliptic, two ends and cross section is semicircular half-shell housing that upper end cap and lower end cap are middle cross section, and the catalyzer that is surrounded by liner is assemblied in the interior formation of the cavity catalyst converter assembly of upper end cap and the formation of lower end cap make-up; One end of suction tude and outlet pipe is assemblied in respectively catalyst converter assembly both sides; The suction tude the other end is equipped with front adpting flange, and the outlet pipe the other end is equipped with rear adpting flange.
Aforesaid ternary catalyzing unit, upper end cap and lower end cap shell rim all have flanging, and the convenient encapsulation of flanging is end cap up and down, consists of air-locked hollow cavity.
Aforesaid front adpting flange and rear adpting flange end face all have for the welding screw that ternary catalyzing unit is installed, and the welding screw is convenient to be installed in ternary catalyzing unit on the vent systems.
The beneficial effects of the utility model are: (1) is adopted oval-shaped cavity not only to save the space but also has been reached the effect of three-element catalytic.(2) adopt the purifier of punching press form to connect the front adpting flange of front end, and adopt Type of Welding to connect.By the design to gas exhaust manifold caliber and shape, well the control engine air flow direction makes the catalyzer in the ternary catalyzing unit can more participate in reaction, improves the transformation efficiency of exhaust emissions.
