Diesel carbon filters are used with monolithic wall flow substrates coated with a catalyst. The engine reduces the combustion temperature of the soot, which allows the filter to be automatically registered during periods of high exhaust gas temperature. We offer the number of diesel filter catalysts that have been developed, including noble metal and base metal formulas. Our filters are manufactured in a sophisticated production unit in the use of inputs of optimum quality factor and modular technology in compliance with established international standards.
