Abstract
The utility model relates to a hot junction assembly integrating a welded exhaust manifold with a ternary catalysis cleaner and pertains to parts and components of automobiles. The utility model essentially solves the shortcomings associated with prior exhaust manifolds of engines and ternary catalysis cleaners that the tail gas can't meet Europe III and Europe IV emission standard, and the exhaust manifolds are of high cost. The utility model is characterized in that the casing in the welded exhaust manifold and the air intake end of the ternary catalysis cleaner, and the air-out end of the ternary catalysis cleaner and the air intake end of the connection pipe are connected by welding. The utility model employs a structure that welds an exhaust manifold of light weight and small specific heat volume directly with a ternary catalysis cleaner, so the tail gas after passing the cleaner will maintain a temperature higher than the preset one, which can maintain the initial conversion efficiency of the cleaner. Therefore, the cleaner can reach firing temperature in shorter time, so as to improve the conversion efficiency of the cleaner. The utility model can meet well the Europe III and Europe IV emission standard, even higher environmental protection requirement, and is of low cost and price.
Description
Technical field
The utility model belongs to auto parts and components, specifically a kind of parts that are used for the tail gas behind the engine combustion is risen set and catharsis.
Background technique
The available engine gas exhaust manifold is generally the Cast Steel that wall is very thick and quality is heavy, because the specific heat capacity of this Cast Steel manifold is very big, therefore, when the motor initial start, exhaust temperature by purifier is lower, cause purifier initial conversion efficient very low, thereby have influence on the transformation efficiency of purifier.Simultaneously, there is expensive, the defect of high cost of price greatly in the enmgine exhaust of Cast Steel because of its quality.
Summary of the invention
The purpose of this utility model provides a kind of integrating welding type gas exhaust manifold and ternary catalyst purifier integrated hot end assembly, its discharge tail gas can satisfy Europe 3, Euro IV Emission Standards preferably, even the environmental requirement of higher standard, and have low price, advantage that cost is low.
The utility model be achieved in that between housing in the welding type enmgine exhaust and the inlet end in the ternary catalyst purifier and between the inlet end of outlet side in the ternary catalyst purifier and connecting tube all by being welded to connect.
Housing in the said welding type enmgine exhaust is stamping forming upper shell of thin-wall boards and lower shell body, between upper shell and the lower shell body, between housing and four bronchuses and between four bronchuses and the forward flange all by being welded to connect.
The utility model makes and predesignates the high temperature of temperature by the tail gas maintenance of purifier by adopting light weight, gas exhaust manifold and the structure that ternary catalyst purifier directly is welded to connect that specific heat capacity is little, can keep purifier initial conversion efficient.Therefore, purifier can reach initiation temperature in the very fast time, thereby improves the transformation efficiency of purifier significantly.Simultaneously, because adopting, the enmgine exhaust of this hot junction assembly and ternary catalyst purifier be welded to connect, therefore, integral rigidity is better, purifier and motor are rigidly connected by engine support, have also strengthened the enmgine exhaust supporting effect, help reducing vibration.The bellows that welds together with the ternary catalyst purifier rigidity also can reduce the enmgine exhaust vibration effectively, prolongs the working life of hot junction assembly.

Accompanying drawing is the utility model structural representation, link plate, 10--thermal shield support, 11--bellows, 12--outlet pipe, 13--rear flange, 14--hook under 1--upper shell, 2--lower shell body, 3--ternary catalyst purifier, 4--connecting tube, 5--bronchus, 6--forward flange, 7--manifold support, 8--lambda sensor nut, the 9--.
Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: upper shell 1 in the welding type enmgine exhaust and lower shell body 2 are by the thin-wall boards impact briquetting, all by being welded to connect, all promptly become the utility model between the inlet end of housing and ternary catalyst purifier 3 and between the inlet end of the outlet side of ternary catalyst purifier 3 and connecting tube 4 between upper shell 1 and the lower shell body 2, between housing and four bronchuses 5 and between four bronchuses 5 and the forward flange 6 by being welded to connect.
During use, forward flange 6 and rear flange 13 are connected with motor and baffler respectively, lambda sensor nut 8 is connected with lambda sensor, and manifold support 7 is connected with thermal shield with thermal shield support 10, and following link plate 9 is connected with car body respectively and gets final product with hook 14.
