摘要

The engine (1) has a three-way catalytic converter (3) arranged in an exhaust line (4) between an engine outlet and a pressure wave supercharger inlet, where the catalytic converter is additionally provided with a particle filter function. A particulate filter is arranged in the exhaust line after a pressure wave supercharger outlet. A nitrogen oxide post-treatment system is arranged after the filter. A pressure wave supercharger (2) is controlled such the pressure wave supercharger enriches exhaust gas with oxygen by purging the exhaust gas with air with respect to the outlet. An independent claim is also included for a method for controlling exhaust gas temperature in a petrol engine.
