Abstract: An apparatus, system, and method are disclosed for utilizing a diesel aftertreatment device (112) between the high pressure (110) and low pressure turbine stages (116) of a two-stage turbocharging system (100). The diesel aftertreatment device is connected in series between the high pressure turbine and the low pressure turbine such that the diesel aftertreatment device receives inflow from the high pressure turbine and provides outflow (114) to the low pressure turbine. A bypass mechanism (106) is provided such that at low engine speeds or loads, engine exhaust (104) flows through the high pressure turbine as well as the diesel aftertreatment device, but at high engine speeds or loads, the high pressure turbine and diesel aftertreatment device are bypassed, thereby allowing the engine (102) to operate more efficiently while still effectively removing pollutants from the engine exhaust.

Abstract: An apparatus, system, and method are disclosed for preventing turbocharger overspeed in a combustion engine (102). The method includes determining (602) a turbocharger error term (202) as a difference between a nominal turbocharger maximum speed (206) and a current turbocharger speed. The method further includes determining (604) a turbocharger speed derivative with respect to time (204). The method includes calculating (606) a turbocharger control response based on the turbocharger error term (202) and the turbocharger speed derivative with respect to time (204). The turbocharger control response (210) may be a modified turbocharger maximum speed (210A) calculated by determining a reference speed multiplier based on the turbocharger error term (202) and the turbocharger speed derivative with respect to time (204), and multiplying the reference speed multiplier by the nominal turbocharger maximum speed (206). The method thereby smoothly anticipates turbocharger transient events, and prevents an overspeed condition of the turbocharger.

Abstract: 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.

Abstract: Managing firing fraction transitions of a variable displacement internal combustion engines by (a) avoiding transport delays in an Exhaust Gas Recirculation (EGR) feed by starting movement of an EGR valve position after a decision to transition to a new firing fraction has been made, but prior to the start of the transition and (b) adjusting the EGR valve as needed during the transition so as to maintain an EGR fraction within a predetermined range during the transition. By performing both (a) and (b), spikes of nitrous oxide (NOx) and/or hydrocarbon emissions are reduced or altogether eliminated during the transition.

Abstract: An intake air circuit is structured to transmit intake air from a turbocharger compressor to an intake manifold of an engine. A charge air cooler ("CAC"), a bypass line, and a bypass heater are each positioned along the intake air circuit in parallel with each other. A first control valve is structured to controllably divert the intake air around the CAC. A second control valve is structured to controllably divert the intake air around at least one of the bypass line and the bypass heater. A controller operatively coupled to each of the engine, and the first and second control valves is structured to control each of the first and second control valves to cause the intake air to flow along a determined desired flow path based on each of measured ambient temperature and measured engine load.
