How it works (continued)
The converter element is constructed from a ceramic material, and includes an internal corrugated structure having noise baffle patterns. In addition, the converter element contains several reactive components, including platinum, palladium, rhodium, and cerium, with a magnesium alum-silicate carrier. This allows a low linear expansion, a low coefficient of thermal expansion, and a high resistance to thermal shock. The platinum and palladium components act as oxidizing catalysts for hydrocarbons and carbon monoxide. When these two products are oxidized, the resulting compounds are water and carbon dioxide, which are relatively harmless and environmentally friendly. The rhodium component behaves as a reduction catalyst for nitric oxides, thereby producing nitrogen and aiding in carbon dioxide production. Finally, the cerium element acts to promote oxygen storage in the converter element to improve the oxidation efficiency and conversion of the volatile exhaust gases to relatively benign end-products.
As a result, the generator maybe operated efficiently, quietly, and without fear or danger of the potentially fatal build-up of poisonous by-products. Moreover, as the EnviroGenCat™ device is easily attached and removed, the overall operation and use of generator is not affected, nor is the portability of the generator.
