Abstract

A method of operating an exhaust system in an internal combustion engine 110 equipped with a Diesel Particle Filter 282 downstream of a Lean NOx Trap 281, where the method comprises monitoring a sulphur (SOx) level accumulated in the Lean NOx Trap, generating a DeSOx regeneration request if the monitored SOx level is above a first threshold and triggering a DeSOx regeneration phase if a DPF regeneration phase is active. Preferably before triggering the DeSOx regeneration phase the soot level accumulated in the DPF is monitored and if the SOx level is above or equal to a second SOx threshold value, which is greater than the first SOx threshold, and the soot level is below a DPF soot value threshold the regeneration of the DPF is triggered. Also, the DeSOx regeneration phase is only triggered when a high oxygen combustion mode is activated and the percentage that the DPF is regenerated and the temperature of the DPF are above a threshold.
