Abstract
Ash accumulation in heavy duty and light duty diesel filters has become a growing concern due to its negative impact on filter performance over time. Performance issues include increased backpressure and increased fuel penalty. An additional concern is frequency of filter ash cleaning which contributes to overall maintenance and operational costs.
A new ash storage concept filter is discussed in this paper. This concept proposes an exchange between inlet and outlet cells, redistributing surface area and volume resulting in more ash storage and improved pressure drop over traditional filters. Overall filter performance (pressure drop, regeneration, ash/ceramic interactions) was evaluated in the laboratory and results are reported in this paper. This paper will discuss in detail the ash storage concept and its benefits in filter performance.
