    摘要: A system for a vehicle includes a first ozone sensor that generates a first sensor signal indicating a first amount of ozone in air flowing into a radiator. A second ozone sensor generates a second sensor signal indicating a second amount of ozone in air flowing out of the radiator. A control module receives the first sensor signal and the second sensor signal and determines an ozone conversion rate based on the first sensor signal and the second sensor signal.

    摘要: An exhaust gas treatment system for an internal combustion engine is provided, including an exhaust gas conduit, a pressurized vessel, a selective catalytic reduction (“SCR”) device, and a control module. The internal combustion engine has a plurality of pistons and an engine off condition that indicates that the pistons are generally stationary. The exhaust gas conduit is in fluid communication with, and configured to receive an exhaust gas from the internal combustion engine. The pressurized vessel stores a solid ammonia gas producing material. The pressurized vessel is selectively activated to heat the solid ammonia gas producing material into an ammonia gas. The ammonia gas is released into the exhaust gas conduit. The SCR device is in fluid communication with the exhaust gas conduit and is configured to receive the ammonia gas.

    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: A method for monitoring performance of a passive selective catalytic reduction system includes operating the internal combustion engine in a preconditioning mode. Subsequent to the preconditioning, an air/fuel excursion is introduced into the exhaust gas feedstream and a signal output from a sensor monitoring the exhaust gas feedstream in the selective catalytic reduction system during the air/fuel excursion is monitored. An operating effectiveness is determined for the selective catalytic reduction system correlated to the signal output from the sensor monitoring the exhaust gas feedstream.

    摘要: An optical receiver is provided with inputs for receiving two fiber optic lines. The two fiber optic lines carry redundant data. An optical interface passes the respective signals therein to a comparison unit. The comparison unit compares the signals and determines which has the better quality and passes the better quality signal on to a processing interface. Clock data for operating the comparison unit is extracted from the optical signals.

    摘要: A method and circuit for performing a wired-or function in a differential transmission environment are disclosed. The wired-or function is realized by enabling the differential driver portion of the differential transceiver when the signaling path is to be driven with a logical true signal and disabling the differential driver portion when a logical false signal is to transmitted to the signaling path. In a preferred embodiment, a 1394 backplane node (a node is a single connection to the bus which may or may not be shared by multiple devices) is implemented using commercially available chips including a physical arbiter, a link controller, a differential transceiver, a programmable logic device, and some additional transistors.
