Apparatus and method for NOx reduction. A reducing catalyst is provided on a monolith or other suitable catalytic converter element. A multi-mode fuel processor of liquid hydrocarbon fuel is capable of delivering a required quantity and composition of a reducing agent while operating in a desired sequence of the following modes: partial oxidation, incomplete pyrolysis, evaporation, combustion, and atomization. Temperature sensors detect the catalyst temperature and means are provided to introduce the reducing agent into the exhaust stream at a rate correlated to the measured temperature. Means also provided to implement a predetermined control algorithm. |
