Abstract
The ability to regenerate a DPF at any engine operation point represents a considerable challenge. One device that is proving to provide a reliable solution with minimal complexity and costs is the diesel Vaporizer system. The system introduces vaporized diesel fuel into the exhaust system, which is then oxidized across a Diesel Oxidation Catalyst (DOC), generating an exothermal reaction and thus increasing the gas temperature, resulting in the oxidation of the soot. When compared to the alternatives, the benefits can be seen in the lower power consumption compared to other heating device, the lower fuel penalty (up to -50% compared to engine regeneration) and in the uncritical secondary emissions. But the major advantage remains that, by avoiding the engine post injection, a safer regeneration without oil dilution issues and critical exothermal reactions can be achieved.
