    摘要： An exhaust gas treatment system for an internal combustion engine is provided and includes an exhaust gas conduit, a generator, an electrically heated catalyst (“EHC”) device, and a control module. The exhaust gas conduit is in fluid communication with, and is configured to receive an exhaust gas from the internal combustion engine. The generator operates at a generator speed to produce electrical power. The EHC device is in fluid communication with the exhaust gas conduit. The EHC device includes a monolith structure that is divided into a plurality of segments that define discrete resistive paths. The resistive paths are selectively connected to the generator for receiving electrical power. The control module is in communication with the EHC device, the generator, and the internal combustion engine. The control module includes control logic for determining the generator speed.

    摘要： An exhaust treatment system for an engine includes a selective catalyst reduction (SCR) treatment module that controls a valve and an air pump to deliver air to an SCR catalyst in response to the engine turning off. An SCR loading module controls the valve and the air pump to deliver air to an exhaust manifold and controls a dosing system to deliver a dosing agent upstream of the SCR catalyst when a temperature of the SCR catalyst is less than a temperature threshold and the SCR catalyst is not saturated with ammonia.

    摘要： The capacity of a platinum-containing diesel oxidation catalyst (DOC) to simultaneously convert NO to NO2, CO to carbon dioxide, and remaining hydrocarbons to carbon dioxide and water in the exhaust system of a vehicle diesel engine may be evaluated and diagnosed using measured DOC exhaust inlet temperatures and outlet temperatures at a relatively high exhaust temperature and, soon thereafter, at a relatively low exhaust inlet temperature. Values of the platinum-containing DOC exotherms at the high and low DOC inlet temperatures are found to provide a basis for evaluation of both NO conversion and the HC and CO conversion capabilities of the DOC. The process may be repeated as the catalyzed DOC conversion efficiency changes with use. The practice may also be used to evaluate the performance of oxidation catalysts used in a like way in treating the exhaust from a lean-burn gasoline engine.

In one embodiment, the method includes providing a coupling between a battery pack and an internal combustion engine exhaust system, the coupling comprising: a duct positioned between the battery pack and the internal combustion engine exhaust system, the duct including at least one one-way valve positioned to allow battery cell exhaust to pass from the battery cell to the internal combustion engine exhaust system; detecting a thermal event; activating a fan, an air pump, or both in response to the thermal event to force the battery cell exhaust through the coupling; and treating the battery cell exhaust in the internal combustion engine exhaust system.
