Abstract: An after-treatment (AT) system used to treat an exhaust gas flow emitted by an internal combustion engine includes a catalyst monolith configured to actively remove a pollutant from the exhaust gas flow. The AT system also includes a heating element configured to heat the catalyst monolith. The AT system additionally includes an energy-discharge unit configured to power the heating element. The energy-discharge unit includes an energy-storage device configured to supply electrical energy. The energy-discharge unit also includes a capacitor configured to receive the electrical energy from the energy-storage device and discharge the received electrical energy to power the heating element and thereby heat the catalyst monolith. A vehicle having an internal combustion engine operatively connected to such an AT system is also contemplated.

Abstract: An electrically-heated catalytic converter includes: a substrate made of ceramic, the substrate including a catalyst coated layer; electrode films made of ceramic, the electrode films being disposed on a surface of the substrate; electrode terminals made of ceramic, each of the electrode terminals being secured to a corresponding one of the electrode films; and external electrodes each attached to a corresponding one of the electrode terminals via a brazing filler metal. A thermal expansion coefficient of the brazing filler metal is equal to or higher than a thermal expansion coefficient of the electrode terminals, and is equal to or lower than a thermal expansion coefficient of the external electrodes. The thermal expansion coefficient of each of the electrode terminals decreases from a portion at which the electrode terminal is joined to the brazing filler metal toward a portion at which the electrode terminal is joined to the corresponding electrode film.

Abstract: A catalyst article having an extruded support having a plurality of channels through which exhaust gas flows during operation of an engine, and a single layer coating or a bi-layer coating on the support, where the extruded support contains a third SCR catalyst, the single layer coating and the bilayer-coating contain platinum on a support with low ammonia storage and a first SCR catalyst. The catalytic articles are useful for selective catalytic reduction (SCR) of NOx in exhaust gases and in reducing the amount of ammonia slip. Methods for producing such articles are described. Methods of using the catalytic articles in an SCR process, where the amount of ammonia slip is reduced, are also described.
