摘要： An exhaust treatment system is provided. The system may include a particulate trap configured to remove one or more types of particulate matter from an exhaust flow of an engine. The system may also include a catalyst configured to chemically alter at least one component of the exhaust flow. Further, the system may include an exhaust conduit configured to direct the exhaust flow from the engine to the particulate trap and the catalyst. In addition, the exhaust treatment system may include a heating system configured to maintain the temperature of the catalyst above a first predetermined temperature. The heating system may also be configured to periodically raise the temperature of the particulate trap above a higher, second predetermined temperature to thereby effectuate a regeneration of the particulate trap by oxidizing particulate matter accumulated in the particulate trap.

摘要： A parasitic load control system is provided. The system may include an exhaust producing engine and a fuel pumping mechanism configured to pressurize fuel in a pressure chamber. The system may also include an injection valve configured to cause fuel pressure to build within the pressure chamber when in a first position and allow injection of fuel from the pressure chamber into one or more combustion chambers of the engine when in a second position. The system may further include a controller configured to independently regulate the pressure in the pressure chamber and the injection of fuel into the one or more combustion chambers, to increase a load on the fuel pumping mechanism, increasing parasitic load on the engine, thereby increasing a temperature of the exhaust produced by the engine.

摘要翻译： 提供一个寄生负载控制系统。 该系统可以包括排气产生发动机和构造成对压力室中的燃料加压的燃料泵送机构。 该系统还可以包括配置成当处于第一位置时使燃料压力建立在压力室内并且当处于第二位置时允许将燃料从压力室喷射到发动机的一个或多个燃烧室中的喷射阀。 该系统还可以包括控制器，该控制器被配置为独立地调节压力室中的压力和将燃料喷射到一个或多个燃烧室中，以增加燃料泵送机构上的负载，增加发动机上的寄生负载，从而增加 由发动机产生的废气的温度。

摘要： A system for recirculating exhaust gas in an engine system includes a turbocharger and an exhaust gas recirculation system. The turbocharger includes a turbine driven by the exhaust gas from an engine, and a compressor operatively connected to the turbine. The compressor includes an air inlet and a diffuser portion located downstream of the air inlet. The exhaust gas recirculation system includes a fluid passage having an inlet fluidly connected to an outlet of the engine, and an outlet fluidly connected to the diffuser portion of the compressor and located downstream of the air inlet of the compressor.
