Abstract
The utility model discloses a novel porcelain three-way catalyst which comprises a casing, linings, carriers and air inlet and outlet end cones. A bent part extending inwards is arranged between the end cones and the casing. The novel porcelain three-way catalyst provides the technical proposal can effectively solve the technical problems that the end surface of the linings of the porcelain three-way catalyst in an exhaust system of an internal combustion engine of a motor vehicle directly contacts waste gas, and can be blasted slowly by the gas, once the linings are blasted to a certain extent, the linings are burned, and thus the entire catalyst loses the effectiveness. Compared with the traditional structure, the three-way catalyst can cause gas stream not to directly blow to the linings through optimizing the design of the end cones, thus the linings are protected; the durability of the catalyst can be improved while the cost remains unchanged. The three-way catalyst also has the characteristics of simple structure, convenient realization, low cost, long service life, etc.
Description
Technical field
The utility model belongs to the internal combustion engine of motor vehicle releasing system, specifically, relates to a kind of new ceramics ternary catalyzing unit.
Background technique
In the prior art, ceramic ternary catalyzing unit encapsulation is by carrier substantially, liner, housing, and air inlet and outlet end awl is welded, liner plays immobilization carrier, heat insulation and vibration damping, be the part that ceramic ternary catalyzing unit can not lack, it has determined durability and other correlated performance of catalyst converter.The end cap of traditional catalyst converter is simple cone structure, and high-temp waste gas enters carrier from end awl inlet, because the end face of liner directly contacts with waste gas, and can be by slowly deflation of gas.Because the important function of liner, thereby must consider the durability of liner in package design, from the angle of passive protection, the port of liner itself needs special design prevent the damage of this deflation to catalyst converter.In case to certain degree, liner will be burnt liner by deflation, whole like this catalyst converter will lose efficacy.
The model utility content
Technical problem to be solved in the utility model is, in the internal combustion engine of motor vehicle releasing system, end face for ceramic ternary catalyzing unit liner directly contacts with waste gas, can be by slowly deflation of gas, in case liner is arrived certain degree by deflation, liner will be burnt, the technical problem that whole like this catalyst converter will lose efficacy, and a kind of novel tertiary catalyst converter is provided.
Technological scheme provided by the utility model is that a kind of new ceramics ternary catalyzing unit comprises housing, liner, carrier and air inlet and outlet end awl, is provided with the curved shape portion that extends internally between described end vertebra and the housing;
Described curved shape portion is the part on the described end vertebra, described extending inward as along the end face of described housing and the liner extension of central axis to housing;
The distance that described curved part extends internally is greater than the two thickness sum of described housing and liner;
Described curved part is connected with housing, liner, carrier respectively successively;
Describedly be connected to welding.The air-flow diameter of the carrier of flowing through is reduced.
Technological scheme provided by the utility model; can effectively solve in the internal combustion engine of motor vehicle releasing system; end face for ceramic ternary catalyzing unit liner directly contacts with waste gas; can be by slowly deflation of gas; in case liner is arrived certain degree by deflation; liner will be burnt; the technical problem that whole like this catalyst converter will lose efficacy; compare with conventional construction; the utility model makes air-flow can not directly blow to liner by the design of optimal design end awl, thus protective lining; in addition; because adopt this structure, liner itself has not just required special anti-deflation structure, thereby has saved cost; perhaps by adopting by adopting the end awl and the package design of this structure; liner itself is not done change simultaneously, can improve the durability of catalyst converter like this, and cost remains unchanged; also have simple in structure in addition; it is convenient to realize, cost is low; characteristics such as long service life.
Description of drawings
In conjunction with the accompanying drawings, the utility model is further described.
Fig. 1 is the prior art structural representation;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the structural representation of the utility model curved part.
Wherein, 1 is carrier; 2 is liner; 3 is housing; 4 are the end awl.
Embodiment
As Figure 1-3, the utility model provides a kind of new ceramics ternary catalyzing unit, comprises housing 3, liner 2, carrier 1 and air inlet and outlet end awl 4, is provided with the curved shape portion that extends internally between described end vertebra and the housing 3;
Technological scheme provided by the utility model, compared with prior art, prior art is that end awl 4 direct smoothed curves are connected with housing 3, causes high-temp waste gas directly to blow to the end face of liner 2 like this; And the design of the technical solution of the utility model is that a curved part is set, and avoids high-temp waste gas directly to blow to the end face of liner 2.
In the technological scheme provided by the utility model, described curved shape portion is the part on the described end vertebra, described extending inward as along the end face of described housing 3 and liner 2 extension of central axis to housing 3; The distance that described curved part extends internally is greater than the two thickness sum of described housing 3 and liner 2; Described curved part is connected with housing 3, liner 2, carrier 1 respectively successively; Describedly be connected to welding.The air-flow diameter of the carrier 1 of flowing through is reduced.
Catalyst converter end awl 4 and package design method in the technological scheme provided by the utility model belong to internal-combustion engine and pollute the control field.It is to bore 4 liners of protecting in the encapsulation of ceramic catalytic device 2 by designing a special end.
Technical conceive provided by the utility model, main mode is not allow waste gas directly blow to the end face of liner 2, so just design a step-like end awl 4, allowed a ladder of end awl 4 cover the end face of liner 2, avoided contacting of liner 2 end faces and high-temp waste gas as much as possible.
