Abstract

The invention relates to an arrangement for reducing harmful emissions from an internal combustion engine (1) by rapid heating-up of an exhaust gas catalyst (9) which is arranged in an exhaust system (8) belonging to said engine (1), comprising means (11, 16) of supplying hydrogen and means (21; 11, 13) of supplying air to the exhaust system (8) upstream of said catalyst (9), the mixture of hydrogen and air giving rise to spontaneous exothermic combustion in association with the catalyst (9), and also a control unit (5) for controlling the functioning of said means (11, 13, 16, 21). The invention is characterized in that said control unit (5) is adapted to control the supply of air and hydrogen to the exhaust system in connection with starting the engine (1) for a period of time (t) that lasts at least until the exhaust gas catalyst (9) has reached a limit temperature at which its functioning is not hampered by CO or HC poisoning. The invention also relates to a procedure for such reduction in harmful emissions. A short heating-up time for the catalyst (9) is achieved by means of the invention.
