The invention provides a packaging structure for a three-way catalytic converter, an engine assembly and an automobile. The packaging structure for the three-way catalytic converter comprises a primary three-way catalytic converter, a secondary three-way catalytic converter, a connecting pipe and a buffering piece, wherein the primary three-way catalytic converter comprises a primary air inlet pipe, a primary air inlet end cone, a primary cylinder, a primary exhaust end cone and a primary exhaust flange which are connected in sequence; the secondary three-way catalytic converter comprises a secondary air inlet pipe, a secondary air inlet end cone, a secondary cylinder, a secondary exhaust end cone, a secondary exhaust pipe and a secondary exhaust flange which are connected in sequence; and one end of the connecting pipe is connected with the primary exhaust flange, the other end of the connecting pipe is connected with the first end of the buffering piece, and the second end of the buffering piece is connected with the secondary air inlet pipe. The packaging structure for the three-way catalytic converter has the advantages that the catalytic oxidation efficiency is high, the arrangement difficulty can be reduced, and the heat damage effect on peripheral parts can be reduced.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a packaging structure of a three-way catalytic converter, an engine assembly and an automobile. Background technique [0002] TWC (Three-Way Catalytic Converter) is the exhaust gas treatment method commonly used in automobiles at present, which can effectively convert the three harmful gases CO (carbon monoxide), HC (hydrocarbons) and NOx (nitrogen oxides) in the exhaust gas into non-toxic Harmful gases are then discharged into the atmosphere through the exhaust pipe. In the prior art, a single TWC package is adopted, that is, a tightly coupled TWC package or a chassis-type TWC package. The use of a single tightly coupled TWC package has high requirements for the layout space, which is easy to affect the layout of the accessories at the front end and rear end of the engine; the oxidation catalysis of TWC is an exothermic reaction, and the distance between it and the surrounding compon...
