    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, 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”).

    摘要: A system according to the principles of the present disclosure includes a rate determination module, a storage level determination module, and an air/fuel ratio control module. The rate determination module determines an ammonia generation rate in a three-way catalyst based on a reaction efficiency and a reactant level. The storage level determination module determines an ammonia storage level in a selective catalytic reduction (SCR) catalyst positioned downstream from the three-way catalyst based on the ammonia generation rate. The air/fuel ratio control module controls an air/fuel ratio of an engine based on the ammonia storage level.

    摘要: Each link between components connected in a daisy-chain configuration is also connected to a special router that can be configured to bypass any one or more of the components. In this way, one or more failed components can be isolated from the daisy-chain configuration without affecting the ability of the other operational components to continue to operate properly. In one embodiment, the special router has a configuration of horizontal and vertical switches and delay nodes. The switches can be independently and selectively controlled to isolate one or more of the components from the daisy-chain configuration, while the delay nodes delay transmission of the signals to simulate the processing time of the bypassed components. In this way, interference with the processing of the remaining operational components can be minimized. In a mobile telecommunications application where each component is a cell-site modem (CSM) of a base station responsible for communications with a different assigned mobile unit, a single-point CSM failure can be detected and isolated in real time without adversely affecting the ability of the remaining operational CSMs to continue to operate, even without interrupting active support of current calls.
