Abstract
A vehicle includes an arrangement, such as an internal-combustion engine coupled with a generator, for converting the energy in fuel into electrical form, while generating exhaust. An exhaust cleaning arrangement, such as a catalytic converter, preferably operating at a high temperature, cleanses the exhaust. During deceleration of the vehicle, excess electrical energy is used to heat the exhaust cleaning arrangement.
