Abstract
The invention relates to a three-way catalyst converter. The three-way catalyst converter comprises a compressed spring bolt, a front connecting flange, an air inlet pipe insulation cover, an air inlet pipe, a barrel body insulation cover, a front end cover, a rear end cover, a barrel body, a gasket, a catalyst, an exhaust pipe, an oxygen sensor nut, a hook, a rubber lifting lug and a rear connecting flange, wherein the catalyst is cylindrical; one end of the air inlet pipe and one end of the exhaust pipe are respectively assembled on two sides of a catalyst converter component; the front connecting flange is installed at the other end of the air inlet pipe; the rear connecting flange is installed at the other end of the exhaust pipe. The three-way catalyst converter adopts a cylindrical cavity to effectively utilize limited space to achieve the effect of three-way catalysis, meanwhile adopts a punching type purifier to be connected with the front connecting flange at the front end, and adopts a welding connection type. The airflow direction of an engine is well controlled through design of the pipe diameter and the shape of the exhaust manifold, the fact that the catalyst in the three-way catalyst converter reacts more sufficiently is ensured and the conversion efficiency of exhaust tail gas is improved.
Description
Technical field
The present invention relates to a kind of ternary catalyzing unit, belong to technical field of engines.
Background technique
The imperfect combustion harmful gases such as CO, HC and the NOx discharged that produce mainly are pooled to ternary catalyzing unit reaction by purifier by ternary catalyzing unit, and oxidation and reduction change harmless carbon dioxide, water and nitrogen into, meet emission request.Current three-way catalyst mainly wraps up with liner and is placed in metal shell, and ensures that catalyzer is unlikely to burst when being subject to the outside cooling suddenly of car body.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provides a kind of ternary catalyzing unit, takies ground disk space less, is convenient to be installed on various types of chassis.
Ternary catalyzing unit of the present invention, comprises stage clip bolt, front adpting flange, suction tude thermal shield, suction tude, cylindrical shell thermal shield, front cover, rear end cover, cylindrical shell, liner, catalyzer, outlet pipe, lambda sensor nut, hook, rubber hanger, rear adpting flange; It is characterized in that: described catalyzer is cylindrical, described liner is wrapped in described catalyzer periphery, described front cover and described rear end cover be middle cross section be circular, closes up in two ends and cross section is circular cylindrical shell, the catalyzer being surrounded by described liner is assemblied in that cavity that described front cover and described rear end cover make-up formed is interior forms catalyst converter assembly; One end of described suction tude and described outlet pipe is assemblied in described catalyst converter assembly both sides respectively; The described suction tude the other end is equipped with described front adpting flange, and the described outlet pipe the other end is equipped with described rear adpting flange.
Aforesaid ternary catalyzing unit, thermal shield edge all has flanging, the upper and lower thermal shield of the convenient encapsulation of flanging, the hollow cavity of formation.
Aforesaid front adpting flange and rear adpting flange end face all have the stage clip bolt for installing ternary catalyzing unit, and stage clip bolt is convenient to be arranged on ternary catalyzing unit in vent systems.
The invention has the beneficial effects as follows: (1) adopts circular cavity to make use of the effect that the confined space reaches three-element catalytic efficiently.(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 control engine air flow and flow to, make the catalyzer in ternary catalyzing unit more can participate in reaction, improve the transformation efficiency of exhaust emissions.
