International Journal of Vehicle Design (IJVD), Vol. 25, No. 4, 2001

Abstract: Improvements in diesel engine aftertreatment technology are needed to meet future environmental quality goals. Systems using recently developed compact plasmatron fuel converters in conjunction with aftertreatment catalysts could provide new opportunities for obtaining significant pollution reductions. Use of compact plasmatron reformers to produce hydrogen-rich gas for the regeneration of NO_x absorber/absorbers and particulate traps could provide significant advantages. Catalyst requirements are determined and overall system characteristics are evaluated. The options made possible by use of onboard hydrogen generation for regeneration of catalysts are briefly described. Recent tests of conversion of diesel fuel to hydrogen-rich gas using a low current plasmatron fuel converter with non-equilibrium plasma features are described.
