Previous research has shown that hydrogen and carbon monoxide are superior agents for the regeneration and de-sulfation of Lean NOX Traps (LNT). It has also been proposed that a syngas stream could be useful for active regeneration of Diesel Particulate Filters (DPF). The challenge of supplying syngas on-board a vehicle has always been the design and control of an inexpensive and simplistic fuel processor. This technical paper presents the operating results for a non-catalytic, auto-thermal syngas generator, that converts diesel fuel and a small portion of an engine's exhaust stream, into a syngas stream. Also described, is the general control scheme used to operate the syngas generator.
