Abstract (en)
[origin: WO2013110873A1] The invention relates to a method for the thermal protection of the components of the exhaust line of a heat engine according to which the temperatures of the exhaust gases and the walls of the exhaust line are predetermined and according to which, when the component of the exhaust line has reached the maximum temperature limit thereof, this is detected. According to the invention, the method consists of: - determining (54) a setpoint temperature (T3setpoint) of the exhaust gases at the outlet of said engine, and - developing (56) a setpoint richness (φsetpoint) used to ensure said setpoint temperature of the exhaust gases.
