Abstract
A diesel combustion engine system providing improved fuel combustion and exhaust aftertreatment includes: a diesel combustion engine having a liquid fuel intake, an air intake, a reformate intake, and an exhaust outlet; a liquid diesel fuel source in fluid communication with the liquid fuel intake and an on-board catalytic partial oxidation fuel reformer that receives a supply of hydrogen-containing liquid diesel fuel and a supply of air and produces therefrom a hydrogen-rich reformate. An exhaust conduit in fluid communication with the exhaust outlet and the reformer includes a reformate conduit upstream from exhaust aftertreatment components. The system provides for supplying: under conditions of low engine load, reformate or a combination of liquid diesel fuel and reformate to the engine; under conditions of medium engine load, a combination of liquid diesel fuel and reformate to the engine; and, under conditions of high engine load, liquid diesel fuel only to the engine and reformate only to the exhaust conduit.
