Automobile exhaust-purification devices Ultracompact products with excellent purification performance coupled with the advantage of reasonable pricing.
The prototype data of the automobile exhaust gas purification device on which we have been conducting research and development for several years, has showed astonishing results, with “purification performance raised by more than 35% at 1/3 of the size” when compared with existing products. Based on these results, we have newly developed automobile exhaust gas purification devices. The smaller size allows for a high degree of freedom in design. Furthermore, as a result of drastically reducing the amount of metal catalyst that makes up around 80% of the material cost, these devices have the advantage of lower cost. These promising products have a high possibility of being able to be used in not only motorcycles and light automobiles but also in hybrid cars as well.
- Automobile exhaust gas purification device: can also be used for small engines such as portable generators
Trial result: The size is one-third of that of the existing product, and the purification performance is improved by 35% or more.
Overview of an exhaust gas purification device prototype This is a prototype of an exhaust gas purification device (Fig. C bottom) formed into a honeycomb shape (Fig. D) by stacking corrugated wire mesh (Fig. D28), which is wire mesh that is made from knitted SUS wire rods (Fig. B) and corrugated, and plain-woven wire mesh. The purification performance test for this prototype gave an incredible result in which purification performance was improved by at least 35% despite the prototype being 1/3 the size of existing products (Fig. A). We have developed new products based on this result.
Overview of newly developed products
Outline of new products A product that combines metal wire mesh and metal steel foil plates A honeycomb-like structure (Figure D) is used in a corrugated metal mesh (Figure D-28), where wire mesh from knitted metal wire rods (Figure A) is further formed into a corrugated shape, and is layered with a flat foil plate (Figure D-27), in which a metal steel foil plate has been formed into a metal mesh shape. The product is significantly smaller than existing products, and features excellent purifying performance, as well as strength, durability, oxidation resistance, and thermal shock resistance. Characteristics Miniaturization allows for a high degree of freedom in design. This means the amount of metal catalyst used, which accounts for approximately 80% of the raw material cost, can be significantly reduced, allowing us to provide a low-priced product. miniaturization enables a high degree of design freedom.
