Abstract: An assembly and method for storing a reductant, including ammonia, for use in the treatment of NOx in an exhaust stream, is disclosed. The assembly comprises a cartridge having an interior space, a disk formed from compacted reductant adsorbing/desorbing material contained within a heat transfer material, and, an expandable element positioned within the interior space of the cartridge for receiving a plurality of disks within the interior space of the cartridge. The expandable element or conduit may also be used to charge or recharge the adsorbing/desorbing material with ammonia.

Abstract: A device and method relating to the storage and delivery of ammonia for use in an after-treatment device for NOx reduction in an exhaust stream, is disclosed. The device includes a cartridge having an ammonia adsorbing and desorbing material contained therein, and a recharging device for use in recharging the material with ammonia after the ammonia is released to a pre-determined level. The method includes providing a sealable cartridge having an interior, providing a predetermined amount of an ammonia-containing material within the interior of the container, positioning a recharging device within the interior of the sealable cartridge, releasing ammonia gas from the ammonia-containing material into an after-treatment device for use in the exhaust system of a vehicle for the reduction of NOx, introducing liquid ammonia into the recharging device, and recharging the ammonia-containing material for re-use in the exhaust system.

Abstract: A device and method for storage and delivery of ammonia for use on a vehicle, is disclosed. The device includes a sealable container, a predetermined amount of a solid ammonia-containing material, wherein the container is filled with the ammonia-containing material prior to sealing, and a canister for receiving the filled, sealed containers. The method includes loading the canister by stacking a plurality of the filled, sealed containers one on top of the other within the canister, and subsequently compressing and crushing the containers to release the ammonia gas for use in the reduction of NOx in a vehicle exhaust system.

Abstract: A device and method relating to storage of ammonia in a solid form and the subsequent release of gaseous ammonia for use in the selective catalytic reduction of NOx, is disclosed.

Abstract: A method for straightening an eccentric shaft (100, 501) by engaging fillets (201, 601) adjacent an element (101, 509) of the shaft with angled rollers (303, 703), rotating the shaft and selectively applying a compressive rolling force (301, 709) during only a portion of the rotation into the fillets (201, 601) of the shaft through the rollers (303, 703), which results in straightening the crankshaft (100).
