Filed:

Oct 15, 2002

Appl. No.:

10/271188

Inventors:

Stephen P. Heath - Fort Wayne IN

Assignee:

International Truck Intellectual Property Company, LLC - Warrenville IL

International Classification:

B60T 1700

US Classification:

303 1, 1378994, 96147, 303 85

Abstract:

An air supply system for a large vehicle air brake system includes an air compressor for supplying compressed air. The compressed or pressurized air is routed to an air dryer which includes a desiccant bed through which the compressed air flows for drying. The air dryer is located between a wet tank and a dry tank for the air supply system and air moves from the dryer to the wet tank. From the wet tank the air passes through a conduit through the air dryer to the dry tank. The air dryer is mounted on tracks allowing it to withdrawn from between the air tanks for replacement or service.

International Classification:

F01N 3/00

Abstract:

Diesel engine particulate trap regeneration is obtained by concurrently supplying two exhaust gas streams to a particulate trap requiring regeneration. One stream is produced in a reactor/diesel engine operating an efficient stoichiometric ratio. The second stream is produced in a second reactor/diesel engine burning fuel at a low air/fuel ratio to produce an exhaust gas stream carrying a substantial load of unburned hydrocarbons, hydrogen and carbon monoxide. The two streams together carry sufficient thermal energy to ignite the unburned hydrocarbons, hydrogen and carbon monoxide using oxygen from the first exhaust gas stream as oxidizer.
