Abstract
The invention relates to a three-way catalytic converter. The three-way catalytic converter comprises a front connecting flange, an air inlet pipe, a rotary pressing cylinder, a pad, a catalyst, an air exhaust pipe, an oxygen sensor nut and a rear connecting flange. The catalyst is cylindrical; the circumferential outer side of the catalyst is wrapped by the pad; the catalyst wrapped by the pad is assembled in a rotary pressing cavity of the rotary pressing cylinder to form a catalyst component; the air inlet pipe and one end of the exhaust pipe are assembled on the two sides of the catalyst component respectively; the front connecting flange is arranged at the other end of the air inlet pipe; the rear connecting flange is arranged at the other end of the exhaust pipe. Through the adopted round cavity, the limited space is efficiently utilized for achieving the three-way catalytic effect, and meanwhile a stamping type purifier is adopted to be connected with the front connecting flange at the front end, and welding type connection is adopted. The diameter and the shape of an exhaust manifold are designed; the airflow direction of an engine can be well controlled; the more catalyst in the three-way catalytic converter can participate in reaction, and the conversion efficiency of tail gas emission 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 front adpting flange, suction tude, spinning cylindrical shell, outlet pipe), lambda sensor nut, adpting flange, catalyzer, liner; It is characterized in that: described catalyzer is cylindrical, described liner is wrapped in described catalyzer periphery, described spinning cylindrical shell two ends are the cylindrical shell of conical round table, form catalyst converter assembly in the cavity formed after the catalyzer being surrounded by described liner is assemblied in described spinning cylindrical shell spinning; 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 suction tude and outlet pipe all have curvature in Z-direction.
Aforesaid outlet pipe has lambda sensor nut at bending position.
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.
