摘要： Various embodiments of an apparatus, system, and method are disclosed for controlling engine exhaust temperature. For example, according to one exemplary embodiment, an apparatus for controlling the temperature of engine output exhaust of an internal combustion engine 110 during a regeneration event on a particulate matter filter 150 includes a regeneration module 260 and an exhaust temperature manager 470. The regeneration module 260 is configured to determine a desired diesel oxidation catalyst (DOC)140 inlet exhaust temperature during a regeneration event. The exhaust temperature manager 470 is configured to determine an air-to-fuel ratio strategy for achieving a desired air-to-fuel ratio within the combustion chamber 111 for producing an engine output exhaust temperature approximately equal to the desired DOC inlet exhaust temperature 435. The air-to-fuel ratio strategy includes a first mode and a second mode.

摘要： According to one exemplary embodiment, a virtual turbine speed sensor for a multi-stage turbocharger system (180) is disclosed. The multi-stage turbocharger system includes at least two sequential turbochargers (181, 182) each having a compressor (184, 186) and a turbine (183, 185). The virtual turbine speed sensor includes a compressor efficiency module (220) configured to estimate an efficiency of a first compressor of the at least two turbochargers, an inter-stage air temperature module (230) configured to estimate an inter-stage temperature of air between the at least two compressors, and a turbine speed module (240) configured to estimate a speed of a second turbine of the at least two turbochargers. The inter-stage temperature estimate of air is based at least partially on the efficiency of the first compressor and the speed estimate of the second turbine is based at least partially on the inter-stage air temperature estimate.

摘要： This disclosure provides a method and system for determining recommendations for vehicle operation that reduce soot production in view of a diesel particulate filter (DPF) of an exhaust aftertreatment system. Recommendations generated can reduce excessive particulate matter (PM) production during transient engine events and provide for operating conditions favorable for passive regeneration. In this way, less frequent active regeneration of the DPF is needed and/or more opportunities are provided for passive regeneration. The system and method can utilize location and terrain information to anticipate and project a window of operation in view of reducing soot production and soot loading of the DPF, or provide the operator with instruction when such opportunities are present or will soon be encountered.
摘要翻译：本公开提供了一种用于确定针对排气后处理系统的柴油微粒过滤器（DPF）减少烟灰产生的车辆操作建议的方法和系统。产生的建议可以减少瞬态发动机事故期间的过量颗粒物（PM）产量，并为有源再生提供有利条件。以这种方式，需要较少频繁的DPF主动再生和/或为被动再生提供更多的机会。考虑到减少DPF的烟灰生产和烟灰负荷，系统和方法可以利用位置和地形信息来预测和投影操作窗口，或者当这些机会存在或即将遇到时，向操作者提供指导。
