An active diesel particulate filter regeneration system has been developed to remove diesel particulate matter (PM) accumulation from diesel particulate filters. Diesel particulate filters (DPF) are an effective means of significantly reducing PM emissions from vehicles powered by diesel engines. This paper outlines the use of the ActiveClean™ Thermal Regenerator (TR) system to reduce PM emissions in several different applications. Test cell data was collected using a 15.8L diesel engine to provide exhaust flow. The objective of this test was to evaluate the steady state HC, CO and NOx emissions of the engine and TR combination during regeneration of the filter. The data reveals only a slight increase in HC and CO emissions depending on configuration (single-or dual-leg) for steady state regenerations. It also showed that the TR had very little impact on NOx emissions during regeneration.
