摘要： The present invention discloses an exhaust system for an internal combustion engine that provides diesel particulate filter (DPF) failure detection and/or monitoring of nonmethane hydrocarbons (NMHC) for an internal combustion engine. The system can include a main exhaust duct and a secondary exhaust line operative for exhaust gas to pass therethrough. The system has an oxidation catalyst and a main particulate filter located in line with the main exhaust duct. A monitoring particulate filter is also included and located within the secondary exhaust line. The secondary exhaust line and the monitoring particulate filter are located downstream from the main particulate filter.

摘要： An exhaust gas recirculation system for an internal combustion engine is disclosed. The exhaust gas recirculation system can include a first turbocharger and a second turbocharger with a particulate filter located between the two turbochargers. The first turbocharger can have a first exhaust turbine and a first charger while the second turbocharger can have a second exhaust turbine and a second charger. The particulate filter can be located between the first exhaust turbine and the second exhaust turbine and thereby remove particulates from an exhaust gas before it reaches the second exhaust turbine. In some instances, an exhaust gas recirculation line can be included and have an inlet that is located downstream from the particulate filter. In addition, the exhaust gas recirculation line can have an outlet that is located between the first charger and the second charger, or in the alternative downstream from the first charger. It is appreciated that the internal combustion engine can be a diesel engine and the particulate filter can be a diesel particulate filter.
摘要翻译： 公开了一种用于内燃机的废气再循环系统。 排气再循环系统可以包括第一涡轮增压器和具有位于两个涡轮增压器之间的微粒过滤器的第二涡轮增压器。 第一涡轮增压器可以具有第一排气涡轮机和第一充气器，而第二涡轮增压器可以具有第二排气涡轮机和第二充电器。 颗粒过滤器可以位于第一排气涡轮机和第二排气涡轮机之间，从而在到达第二排气涡轮机之前从废气中除去微粒。 在一些情况下，可以包括废气再循环管线并且具有位于微粒过滤器下游的入口。 此外，排气再循环管线可以具有位于第一充电器和第二充电器之间的出口，或者位于第一充电器的下游的出口。 应当理解，内燃机可以是柴油发动机，并且颗粒过滤器可以是柴油微粒过滤器。

摘要： An exhaust control system for an internal combustion engine having a plurality of actuators wherein each actuator controls a predetermined engine parameter. A plurality of sensors are also associated with the engine and each sensor provides an output representative of an engine operating condition. The control system includes a PID controller associated with each actuator and in which each PID controller has an input, an output and a feedback between the input and the output. A distribution function circuit is operatively connected in series with the inputs of the PID controller. The distribution function circuit receives an error signal representative of the difference between a target value and an actual value of one or more engine operating conditions, previously determined control factor values and the feedback from each PID controller as input signals. The distribution function circuit varies the input to each PID controller as a function of the distribution function input signals.
