    摘要： Described here are systems and methods for treating fuel injected exhaust streams. In general, the systems comprise a fuel injector, a pre-combustor, and a fuel combustor. The methods described herein include methods for regenerating a NO x trap or a DPF, and methods for generating a substantially uniform fuel air mixture at a fuel combustor inlet, or a substantially uniform temperature at a fuel combustor outlet. The methods of regenerating a NO x trap typically comprise the steps of injecting fuel into an exhaust stream, passing the stream through a pre-combustor, operating the pre-combustor to at least partially combust the injected fuel, reacting the fuel and exhaust stream mixture within a fuel combustor to generate a reducing gas mixture, and introducing the reducing gas mixture into a NO x trap, whereby the NO x trap is regenerated. Similar methods for regenerating a diesel particulate filter are also described. Control strategies are also provided.

    摘要： An exhaust aftertreatment system is provided with a large channel combustor (107), a fuel reformer (108), and a lean NOx trap (109). The lean NOx trap (109) is denitrated by steps comprising: heating the fuel reformer (108) to steam reforming temperatures by introducing vaporized fuel to the large channel combustor (107) and combusting a portion of the vaporized fuel under lean conditions, then making the exhaust-injected fuel mixture overall rich, whereby the fuel reformer (108) produces syn gas that denitrates the lean NOx trap (109). The fuel reformer (108) has a low thermal mass, whereby it is designed to heat to at least about 500 2C and catalyze steam reforming reaction with each denitration. The large channel combustor (107) is a monolith having an average channel size larger than the fuel reformer (108) and a thermal mass no more than about 20% that of the fuel reformer (108), whereby the large channel combustor (107) facilitates low temperature startup of the fuel reformer (108).
