Abstract: A system and method are disclosed for controlling the temperature of an aftertreatment system, the method including interpreting an aftertreatment indicating temperature, determining that an engine fueling requirement is zero, and disengaging the engine from a transmission in response to the aftertreatment indicating temperature falling below a first threshold value and in response to the engine fueling requirement being zero, where the engine and the transmission comprise a portion of a vehicle powertrain. Alternatively, the method may include interpreting an aftertreatment indicating temperature, determining that an engine fueling requirement is zero, and performing a reduced air flow operation through the engine in response to the aftertreatment indicating temperature falling below a first threshold value and in response to the engine fueling requirement being zero.

Abstract: An exhaust gas aftertreatment system for an internal combustion engine includes an inlet conduit, a reductant decomposition chamber, a first selective catalytic reduction (SCR) catalyst member, a second SCR catalyst member, a mixing chamber, a particulate filter, a reductant delivery system, and a hydrocarbon delivery system. The inlet conduit is configured to receive exhaust gas from the internal combustion engine. The reductant decomposition chamber is fluidly coupled to the inlet conduit and configured to receive the exhaust gas from the inlet conduit. The first SCR catalyst member is fluidly coupled to the reductant decomposition chamber and configured to receive the exhaust gas from the reductant decomposition chamber. The second SCR catalyst member is fluidly coupled to the first SCR catalyst member and is configured to receive the exhaust gas from the first SCR catalyst member.

Abstract: Methods and systems of recirculating exhaust gas in internal combustion engines are disclosed. An internal combustion engine includes a set of cylinders, an intake system disposed in fluid providing communication with the set of cylinders, an exhaust system disposed in fluid exchanging communication with the set of cylinders, and a controller. In response to a detected recirculation condition, the controller prevents fluid communication between the intake system and a subset of the set of cylinders and recirculates exhaust gas between the subset of the set of cylinders and the exhaust system.

Abstract: The disclosure provides a system and method for determining an amount of fuel injected or delivered by a single fuel injector in an internal combustion engine by generating one fuel injection event after the engine has stopped operating. The fuel delivered is statistically analyzed in comparison with a commanded fuel delivery amounts to determine the suitability of fuel injector on-time calibration for the analyzed fuel injector. If the fuel delivered deviates from the commanded amount of fuel delivery by a predetermined value, the fuel injector on-time calibration for the analyzed fuel injector is changed.
