    Abstract: A system (144) comprising a sensor (22), a reformer (146), a reformer electronic control module (150) and a sensor control module (152), wherein the sensor (22) includes an oxygen pump cell (24); an oxygen pump chamber (26); an emf cell (32); a reference chamber (34) providing a fluid connection to the reference gas (30); gas channels in fluid communication with the pump (48,52) and emf electrodes (64,66), the reference gas (30) comprising reformate produced by fuel reformer (146) fuelled by an air-fuel gas mixture having an air-fuel ratio; a heater (72); a temperature sensor (70) disposed in communication with the heater (72) and the sensor control module (152) for maintaining the sensor (22) at a desired operating temperature; a closed loop controlled operation amplifier (40) in electrical communication with the sensor (22), whereby the oxygen pump cell (24) provides sufficient oxygen ions to oxidize an incoming diffusion-limiting fuel flux to the emf cell (32) and maintain a constant emf at the emf cell (32), and wherein a current value represents an equivalent to the air-fuel ratio of the air-fuel gas mixture.

    Abstract: A combined gasoline and hydrogen fueling system (10',110) for a gasoline-powered internal combustion engine (62), including, preferably, a rapid-start catalytic reformer (72) for producing reformate gas (98) containing hydrogen from gasoline (74). The reformate (98) from the reformer (72) is swept by air into the intake manifold (22) of the cold engine where it is mixed with intake air and then drawn into the cylinders and ignited conventionally to start the engine. A computer-based reformer control system (26) optimizes the amount of reformate (98) formed and the resulting reformate/air mixture. The reformer control system (110) interfaces or is integral with a computer-based gasoline and air supply system (10') for the engine (62), the two systems cooperating to optimize a mixture of gasoline (74) and reformate (98) in the intake manifold at all times during warming of the engine and its exhaust catalyst to steady-state operating temperature. Preferably, flow of reformate (98) is terminated thereafter.
