Beschreibung
Zusammenfassung:	A system for preventing the accumulation of unburned hydrocarbons in a line of exhaust gas after-treatment system of an internal combustion engine comprising at least one devise for the reduction of pollutant emissions, wherein the exhaust gas after treatment system is devoid of any pre-catalyst and a procedure is envisioned for the continuous estimation of a mass of unburned hydrocarbons stored at least in the device for the reduction of pollutant emissions, so as to activate a strategy for accelerating the heating of the exhaust line, when the mass of unburned hydrocarbons exceeds a predefined threshold.
