OPTIMIZED MANAGEMENT OF AN SCR CATALYST BY MEANS OF THE PERIODIC REGENERATION OF A PARTICLE FILTER

摘要

According to the invention, the management of a motor vehicle power train includes a method for adjusting the amount (MC) of reducing agent crystals in an exhaust line (11) and/or in the injection device (13), and the amount (MH) of hydrocarbons contained in the catalyst (SCR), wherein the adjustment method includes periodic steps (E1) of regenerating the particle filter (20), which are each triggered on the basis of separate criteria of the amount (MP) of soot contained in the particle filter (20).
