Abstract
An exhaust-gas purification installation for purifying exhaust gas from an internal combustion engine includes an exhaust-gas catalytic converter which is arranged in an exhaust pipe of the internal combustion engine and a catalytic fuel reformer for generating a hydrogen-containing reformer gas which can be fed to the exhaust pipe on an entry side of the exhaust-gas catalytic converter. It is possible for a hydrocarbon-containing fuel, which can be used to operate the internal combustion engine, to be fed to the fuel reformer in order to generate the reformer gas. An exhaust-gas heater can heat the exhaust-gas part-stream which is fed to the fuel reformer. In a method according to the invention, an exhaust-gas part-stream which is removed from the exhaust pipe is heated and fed to the fuel reformer.
