Abstract
A combustion system includes a catalytic oxidizer for oxidizing a mixture of air and fuel vapor. The amount of air provided for mixing with the fuel vapors is determined in accordance with the temperature of the oxidation reaction as measured by a temperature sensor. Controlling the dilution level in this manner provides an efficient vent processing design. The system is used to process vapor emissions emanating from a vehicle fuel tank during refueling.
