More Information
Summary:An apparatus 12 for exhaust gas treatment for an internal combustion engine 1 including a catalytic conversion unit 5 is characterised in that at least the internal combustion engine 1 is configured as a feed device for feeding hydrogenous heating agent, such as hydrogen, to the catalytic active conversion unit 5. The apparatus 12 substantially improves the cold start behaviour of the catalytic conversion unit 5, as well as considerably reduces the emission of pollutants by the internal combustion engine 1. A method for treating exhaust gases using apparatus 12 and a vehicle comprising apparatus 12 is also disclosed.
