ABSTRACT:
A diesel combustion engine comprises multiple particulate filters and corresponding exhaust piping and valving in the exhaust manifold and/or exhaust line, configured to enable regeneration to occur in one of the DPF filters through heating the exhaust from a single cylinder of the engine, while the exhaust from the remaining cylinders is temporarily routed through the other DPF filter during the regeneration event. Flow redirection devices are placed within the DPF filters to direct flow of exhaust gas through the DPF filters during regeneration in a manner to facilitate complete regeneration, including in outer volumes along the interior walls of the DPF filters.
