Filed:
Jul 13, 2007
Appl. No.:
11/827789
Inventors:
Paul J. Troxler - Bellingham WA, US
Assignee:
PACCAR Inc - Bellevue WA
International Classification:
F01N 13/00, F01N 1/16, F01N 13/08, F01N 1/14, F01N 3/02, F01N 5/04, F01N 1/00, B60K 13/04, B60K 13/02
US Classification:
60324, 60 17, 60319, 180309, 180296, 180 892, 180 683, 181239, 181277, 181228, 181248, 181262
Abstract:
A flow diffuser for vehicles of the type having an engine and an exhaust pipe generally includes a substantially tubular body having an outer surface and a first end configured for attachment to an exhaust pipe. The flow diffuser further includes a diffusion portion including at least one channel having a root end located near the outer surface, an exit port, and a channel axis extending between the root end and the exit port, the channel increasing in flow area along the channel axis to reduce exhaust gas velocity.

Reductant Delivery Device

US Patent:
2012017, Jul 12, 2012
Filed:
Jan 10, 2011
Appl. No.:
12/987868
Inventors:
Paul J. Troxler - Bellingham WA, US
Nathan J. Kaemingk - Lynden WA, US
Assignee:
PACCAR INC - Bellevue WA
International Classification:
F01N 3/18, F01N 3/20
US Classification:
60274, 60295
Abstract:
Various diffusion apparatuses are provided for facilitating the injection of a nitrogen-oxides reductant solution, such as urea, into exhaust gas as part of a selective catalytic reduction system. These diffusion apparatuses direct exhaust gas from an exhaust pipe, through a conduit, and into a diffusion chamber where urea is injected. The flow of exhaust gas through the conduit provides improved transport of injected reductant solution into the exhaust pipe, and adhesion of the reductant solution to the walls of the diffusion chamber is reduced.
