    Abstract: One embodiment is a unique strategy for raising exhaust temperatures which includes deactivating a first group of cylinders while maintaining a second group of cylinders in a combustion mode and injecting fuel into each of one of the second group of cylinders not earlier than 2 degrees before top dead center (TDC). The strategy also includes passing fuel rich exhaust from the second group of cylinders into an exhaust pathway and oxidizing at least a portion of the fuel rich exhaust in the exhaust pathway. In one form, the oxidizing occurs independent of any catalytic influence. Other embodiments include unique methods, systems, and apparatus for raising exhaust temperatures and/or regenerating one or more components of an aftertreatment system. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and drawings.

    Abstract: An aftertreatment system is disclosed. The aftertreatment system can include a hydrolysis catalyst disposed within a first canister adjacent to a downstream end of the first canister and a nozzle positioned to inject reductant into the first canister upstream of the hydrolysis catalyst. A particulate collection device, which may be catalyzed to promote NOX reduction in the presence of the reductant, can be disposed within a second canister of the aftertreatment system adjacent to an upstream end thereof. An exhaust conduit can extend from the downstream end of the first canister to the upstream end of the second canister. An interior volume within the exhaust conduit can extend from an upstream end adjacent to and in fluid communication with the hydrolysis catalyst to a downstream end adjacent to and in fluid communication with the particulate collection device.

    Abstract: A vehicle includes: an engine; an EHC (electrically heated catalyst) electrically heated for purifying exhaust gas of the engine; a temperature sensor for sensing the temperature of the EHC; and an ECU that controls the EHC in temperature. The ECU performs a first estimation process and a second estimation process to estimate the temperature of the EHC and accordingly controls electric power applied to energize the EHC, the first estimation process being performed to estimate the temperature of the EHC based on an output of the temperature sensor before the engine starts, the second estimation process being performed to estimate the temperature of the EHC based on the temperature of the exhaust gas emitted by the engine after the engine is started.
