Abstract:
An integrated fuel reformer-engine system characterized by:an on-board catalytic partial oxidation fuel reformer for receiving a supply of hydrogen-containing liquid fuel and a supply of air and converting same into a hydrogen-rich reformate; an engine having a reformate intake, a liquid fuel intake, an air intake, and an exhaust outlet; an exhaust catalyst having an intake for receiving said engine exhaust, said reformate, or a combination thereof, and an outlet for discharging said exhaust after treatment; and control means for adjusting the supply of air and one or a combination of said reformate and said liquid fuel to said engine and for adjusting the supply of reformate to said exhaust catalyst to provide non-stoichiometric lean fueling of said engine and provide low hydrocarbon and NOx emissions over a range of operating conditions from cold-start through to high engine loads; wherein said control means is configured to supply said reformate to said exhaust catalyst for a time sufficient to warm said exhaust catalyst to operational temperature.
