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： An apparatus, system, and method are disclosed for a single-actuated multi-function valve. In one embodiment, an apparatus (100) includes a primary fluid conduit (106), a secondary fluid conduit (114), and a valve (116). The primary fluid conduit extends from an exhaust manifold (104) to an outlet (108) through a high pressure turbocharger (110) and a low pressure turbocharger (112). The secondary fluid conduit extends from the exhaust manifold to the outlet through the low pressure turbocharger. The valve has two flow passages - the first flow passage (118) is a variable restriction within the primary fluid conduit, and the second flow passage (120) is a variable restriction within the secondary fluid conduit. Turning the valve one direction from a nominal position controls the flow ratios in the primary and secondary fluid conduits, while turning the valve in the other direction from the nominal position controls exhaust braking.
