Abstract
The utility model discloses a protection structure of a gasket of a three-way catalyst, relating to the technical field of automobile engine. The utility model comprises a cone and a body case and is characterized in that a bend flanged structure is arranged on the cone (2) of the catalyst. In the flanged structure (3) of the cone, the backside of (6) the cone is bent towards the front side (5) of the cone. By adopting the technical proposal of the utility model, the gas flow of exhaust gas is not capable of blowing directly on the gasket, thereby preventing the gasket from deflation and strengthening the durability of the catalyst; the protection structure is not capable of producing a whirlpool, thereby guaranteeing an exhausting fluency so as not to influence on an exhaust back pressure and an engine performance; in addition, the protection structure has an easy manufacture process and is also very easy to be connected with the body case.
Description
Technical field
The utility model relates to the motor car engine field, in particular, relates to a kind of protection structure of ternary catalyzing unit liner.
Background technique
In the car load vent systems, the catalyst converter liner is parts extremely crucial in the catalyst converter encapsulation, in traditional catalyst converter, the catalyst converter liner is not taked protective measure, and catalyst converter end awl directly is connected with hull outside, thereby makes the catalyst converter liner can not get protection, directly contact with the exhaust of high temperature, be subjected to the corrosion of high-temperature exhaust air easily, cause liner that the loosening catalyst converter that also finally causes of carrier was lost efficacy, the reliability of catalyst converter does not reach requirement; Another kind of traditional catalyst converter is to rely on the reducing of catalyst converter housing to come protective lining (figure two); though the method for housing reducing protection has protected liner not by the high-temperature exhaust air deflation; but there is certain included angle in catalyst converter end awl with the housing joint; make air-flow form eddy current at the carrier inlet place; increase exhaust back pressure, thereby influenced engine performance.
The model utility content
A kind of ternary catalyzing unit liner protection of the utility model structure; its objective is: provide a kind of and solve catalyst converter because the Problem of Failure that liner is caused by deflation; guarantee the fluency of exhaust airstream simultaneously; can not form eddy current; do not influence exhaust back pressure, the ternary catalyzing unit liner that engine performance does not exert an influence is protected structure.
A kind of ternary catalyzing unit liner of the utility model protection structure comprises the end awl, and housing is provided with the turnup structure of bending at described catalyst converter end awl place.
Described end awl turnup structure is set to from the structure of lateral ends awl front side, end awl back to bending.
The bottom of described end awl turnup structure is connected with the catalyst converter housing, thereby the catalyst converter liner is sealed between catalyst converter housing and the catalyst converter inner core.
Even adopt scheme of the present utility model, exhaust airstream can directly not blown on the liner, protective lining strengthens the durability of catalyst converter not by deflation; This kind structure also can not form eddy current, has guaranteed the fluency of exhaust, and to not influence of exhaust back pressure, engine performance can not be affected yet; In addition, this structural manufacturing process is made simple, is connected also with housing not have difficulties.
Description of drawings
Make briefly bright to each width of cloth accompanying drawing of this specification expressed content and the mark among the figure below:
Fig. 1 is the sectional structure schematic representation of a kind of ternary catalyzing unit liner protection of the utility model structure;
Fig. 2 does not protect the sectional structure schematic representation of the ternary catalyzing unit of structure for taking liner;
Fig. 3 protects the sectional structure schematic representation of the ternary catalyzing unit of structure for adopting housing reducing liner;
Be labeled as among the figure: 1, catalyst converter housing; 2, catalyst converter end awl; 3, end awl turnup structure; 4, catalyst converter liner; 5, end awl front side; 6, end awl rear side; 7 catalyst converter inner cores.
Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail embodiment.
As shown in Figure 1, the utility model is a kind of ternary catalyzing unit liner protection structure, comprises end awl 2, and housing 1 is characterized in that: bore the turnup structure that 2 places are provided with bending at described catalyst converter end.
Described end awl turnup structure 3 is set to from the structure of end awl rear side 6 to the front side 5 direction bendings of end awl.
The bottom of described end awl turnup structure 3 is connected with catalyst converter housing 1, thereby catalyst converter liner 4 is sealed between catalyst converter housing 1 and the catalyst converter inner core 7.
Adopt scheme of the present utility model, both guaranteed that air-flow does not directly blow to catalyst converter liner 4, guaranteed that again air-flow does not form eddy current in catalyst converter end awl 2 and catalyst converter housing 1 joint.And the welding of catalyst converter end awl 2 and catalyst converter housing 1 easily is convenient in this kind connection.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above, but specific implementation of the present utility model is not subjected to the restriction of aforesaid way.As long as adopted the improvement of the various unsubstantialities that design of the present utility model and technological scheme carry out, or design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model without improving.
Claims (3)
