Abstract (en)

[origin: DE10017203A1] A method for the desulphurisation of an oxidation catalyst (8), arranged in the exhaust line of a diesel internal combustion engine (1), is disclosed, whereby the diesel internal combustion engine (1) is operated at a lambda value lambda 1 of ca. 0.98 to 0.99 and an exhaust gas temperature T1 of at least 350 DEG C. The oxidative capacity of the oxidation catalyst impaired by sulphur is thus regenerated within a short period and at moderate exhaust temperatures. Diesel internal combustion engines can thus, at least temporarily, be operated using sulphur containing fuel.
