Diesel Particulate Filters (DPFs) have been widely used to control the particulate emissions and have become an indispensable feature of the modern diesel engines. However, DPFs also result in additional fuel consumption from added back pressure and periodic regenerations required for oxidizing the accumulated particulate matter. Aftertreatment calibrations are developed with a significant emphasis on the reducing these penalties. It is desirable to accumulate higher levels of particulate matter before regeneration and perform active regenerations at higher temperatures. This capacity is generally limited by the substrate and catalyst properties and also the inaccuracies in the DPF soot accumulation estimation. Several advancements have been made in the DPF material technologies to mitigate these limitations. This publication describes the performance of various DPF technologies.
