Abstract
The present invention relates to a double-layer treinary catalyzer for car engine. It includes shell body, trinary catalyzer core and gasket. The middle portion of said shell body is single-layer thin-wall structure, in two ends of said shell body, namely front portion and rear portion of said trinary catalyzer core respectively a horn portion with sandwich structure is formed, said horn portion is formed from external layer, heat-insulating layer and internal layer, said heat-insulating layer adopts the heat-insulating material so as to retain exhaust temperature.
Description
Technical field
The present invention relates to the ternary catalyzing unit structure of motor car engine.
Background technique
Automobile three-way catalysts existing standard structure comprises ternary catalyzing unit core 11, liner 12, ternary catalyzing unit housing 13, thermal shield 14, its structure is seen Fig. 1, the centre of ternary catalyzing unit housing 13 and the horn mouth on both sides are individual layer, housing 13 is implemented encapsulation by liner 12 with ternary catalyzing unit core 11, for the radiation heat that stops ternary catalyzing unit causes thermal radiation to peripheral component, apply thermal shield 14.In this structure, in order to make ternary catalyzing unit housing 13 heatproofs, ternary catalyzing unit housing 13 need be chosen thicker thickness, and between ternary catalyzing unit housing 13 and thermal shield 14, to keep the gap, allow moving air take away the ternary catalyzing unit heat, but this can make the entrance and exit temperature of ternary catalyzing unit descend simultaneously, is unfavorable for stricter emission regulation demands.
Summary of the invention
At the deficiency that prior art exists, the present invention proposes a kind of two-layer, ternary catalysis device for automobile engine, under the prerequisite that guarantees effective delivery temperature, reduces the heat load of housing, to adapt to stricter Abgasgesetz.
Technological scheme of the present invention is as follows:
Two-layer, ternary catalysis device for automobile engine includes housing, ternary catalyzing unit core and liner, the housing middle part is the single thin layer wall construction, at the two ends of housing is the place ahead and rear loudspeaker part with dissection of ternary catalyzing unit core, the loudspeaker part is made of skin, insulation layer and internal layer, and insulation layer adopts resolves hot material to keep delivery temperature.
In addition, the thickness at housing middle part reduces to thickness 1.5mm by common 2mm, reduces the heat load of housing significantly, makes it reach low heat capacity, and is high temperature resistant, improves oxidative stability.
Simultaneously, in order to guarantee the retentivity of liner, strengthen liner thickness and be increased to 6mm by common 4mm.
This ternary catalyzing unit compared with prior art has following beneficial effect;
1, loudspeaker partly adopt disconnected hot sandwich structure, can effectively keep delivery temperature;
2, thin walled structures is adopted at the housing middle part, and heat load is little, has low heat capacity, and is high temperature resistant, the advantage of good in oxidation resistance;
3, strengthen liner thickness, can improve the retentivity of liner.
4, this structure does not have thermal shield of the prior art, has saved cost, and the diameter that can strengthen the ternary catalyzing unit core is to adapt to higher Abgasgesetz.
Description of drawings
Fig. 1 is the structural drawing of existing single hull ternary catalyzing unit;
Fig. 2 is a ternary catalyzing unit structural drawing of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
Referring to Fig. 2, this two-layer, ternary catalysis device is made up of liner 22, housing 21 and ternary catalyzing unit core 23.Housing 21 is implemented encapsulation by liner 22 with ternary catalyzing unit core 23, strengthens liner 22 thickness and is increased to 6mm by common 4mm.The housing middle part 211 in the middle of housing 21 is divided into and the loudspeaker part 212 at two ends, for guaranteeing heat radiation, housing middle part 211 is the single thin layer wall construction, thickness 1.5mm, simultaneously in order to keep delivery temperature, the sandwich structure that loudspeaker part 212 has adopted outer A, insulation layer B, internal layer to constitute, it is that outer A and internal layer C are being inserted insulation layer B after the 211 port part welding of housing middle part, opens the combustion temperature with what guarantee that delivery temperature reaches ternary catalyzing unit core 6 as early as possible.
