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.
