A new method of controlling all the harmful Diesel Emissions including Diesel Particulate Matter (DPM), Unburned-Hydrocarbons(UHC), and Nitrogen Oxides(NOx), has been developed and its concept and test results are briefly presented in this paper.Two filters in parallel are used, each alternating operation as the other regenerates. Each filter made in a conventional manner operates at low temperature below 300 degrees Centigrade to help UHC condense onto DPM captured in the filter. A microprocessor-controlled valve system regulates which filter is active or filtering and which is regenerating. DPM accumulates at the active filter, with UHC condensing or being adsorbed on the DPM captured. Catalysts are employed to support the regeneration burn at low temperature. The byproducts of regeneration including UHC are recirculated into Diesel engine combustion chamber for combustion of UHC and reduction of NOx.
