    摘要： The present invention provides systems and methods to improve the performance and emission control of internal combustion engines equipped with nitrogen oxides storage-reduction (“NSR”) emission control systems. The system generally includes a NSR catalyst, a fuel processor located upstream of the NSR catalyst, and at least one fuel injection port. The fuel processor converts a fuel into a reducing gas mixture comprising CO and H2. The reducing gas mixture is then fed into the NSR catalyst, where it regenerates the NSR adsorbent, reduces the NOx to nitrogen, and optionally periodically desulfates the NSR catalyst. The fuel processor generally includes one or more catalysts, which facilitate reactions such as combustion, partial oxidation, and/or reforming and help consume excess oxygen present in an engine exhaust stream. The methods of the present invention provide for NSR catalyst adsorbent regeneration. Control strategies are provided to control the system and methods of the invention.

    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 NOx 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 NOx 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 NOx trap, whereby the NOx trap is regenerated. Similar methods for regenerating a diesel particulate filter are also described. Control strategies are also provided.

    摘要： Catalyst structure, engine, and fuel injection system are disclosed, in which a catalyst structure is positioned between a fuel injector and a combustion chamber in which most or all combustion occurs. The catalyst structure typically promotes some combustion of the fuel, reforming of fuel to generate hydrogen and other reduced species of fuel molecules, or both. The catalyst structure may instead or additionally promote evaporation of fuel droplets. Benefits include reduced emissions of pollutants.

    摘要： Described here are systems and methods for reducing emissions of IC engines using a fuel processor bypass. In general, the systems described here include an exhaust pipe, a bypass pipe, a valve, a fuel processor, a fuel injector, and a NOx trap. When the valve is in the open position, the entire exhaust passes through the bypass pipe. When the valve is in a closed position, the entire exhaust passes through the exhaust pipe. In some variations, the systems described here also comprise a pre-combustor, a thermal mass, a mixer, and/or a DPF. Methods for regenerating or desulfating a NOx trap are also described. Typically these methods include introducing exhaust into an exhaust pipe, opening a valve located at the inlet of a bypass pipe, injecting fuel upstream of a fuel processor, and introducing a reducing mixture into a NOx trap. The injection of fuel may be pulsed or continuous.
