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： An exhaust gas treatment system for an internal combustion engine is provided, including an exhaust gas conduit, a flow-through container of absorbent particles, an electrically heated catalyst (“EHC”) device, a selective catalytic reduction (“SCR”) 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 exhaust gas contains oxides of nitrogen (“NOx”) and water. The flow-through container of absorbent particles is in fluid communication with the exhaust gas conduit and configured to receive the exhaust gas. The flow-through container substantially adsorbs the water from the exhaust gas below a threshold temperature. The EHC device is in fluid communication with the exhaust gas conduit and is configured to receive the exhaust gas. The EHC device is located downstream of the flow through container, and is selectively activated to produce heat.

摘要： An exhaust gas treatment system for an internal combustion engine is provided, including an exhaust gas conduit, an oxidation catalyst (“OC”) device, an electrically heated catalyst (“EHC”) device, a selective catalytic reduction (“SCR”) device, and a control module. The OC device is in fluid communication with the exhaust gas conduit. The OC device adsorbs hydrocarbons and is selectively activated to induce oxidation of the hydrocarbons in the exhaust gas. The EHC device is in fluid communication with the exhaust gas conduit and is configured to receive the exhaust gas. The EHC device is located within the OC device and is selectively activated to produce heat and induce further oxidation of the exhaust gas. The EHC device has an oxidation catalyst compound disposed thereon for converting nitrogen oxide (“NO”) to nitrogen dioxide (“NO2”).
