Production Experience of a Ceramic Wall Flow Electric Regeneration Diesel Particulate Trap

Demonstration projects of many Diesel Particulate Traps have been and continue to be performed. Many experimental trap systems require software customization to an individual vehicle to account for duty cycle and component variations. This level of customization is not practical in a production environment and in a marketplace where a trap system needs to function on many types of engines and duty cycles. This paper describes the production experience of the Donaldson Dual Ceramic Wall Flow Electric Regeneration Diesel Particulate Trap which has overcome specific production and durability obstacles.
