DPF design

Wall-flow ceramic filters from the Huss Group meet soot filtration limits set by Euro VI/Tier 4 requirements in regard to particle separation as well as market requirements for extended life and improved cleaning in heavy-duty and off-road applications. The company's asymmetric ceramic filter design reduces non-burnable substances in the exhaust such as white ash oil residuals by increasing ash-storage and filter capacity. Features of the asymmetric diesel particulate filter (DPF) design and the SiC filter material include reduced backpressure after regeneration, improved fuel consumption, and prevention of engine power loss. In addition, Huss' online diesel burner increases the temperature of exhaust gas for engines with low and alternating loads over the soot ignition temperature threshold of 550°C (1022°F), enabling passive regeneration systems such as fuel born catalysts to function properly.
