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 method of mitigating battery cell failure is provided. 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. Battery failure mitigation systems are also described.

摘要: Catalysts for the water gas shift reaction contain a variety of late transition metals. The catalytic compositions contain a late transition metal carried on a support which is a carbide, nitride, or mixed carbide nitride of a group 6 metal such as molybdenum, tungsten, and mixtures thereof. The late transition metal includes ruthenium, cobalt, nickel, palladium, platinum, copper, silver, or gold. The water gas shift reaction may be catalyzed by contacting a gaseous stream containing carbon monoxide and water with such a solid catalyst composition. In some embodiments, the catalysts are several times more active than known commercial catalysts for the water gas shift reaction.
