<p>The invention relates to a method that consists of: a) determining a value representative of the temperature (Tavt) of the exhaust gases flowing in an exhaust duct of said engine upstream from the turbine of a turbocharger; b) comparing said value representative of said temperature with a predetermined threshold value (Tavt_seuil); c) if said representative value is higher than said predetermined threshold value, initiating the timing-out of a first time delay (tempo_in) during which steps a) and b) are repeated and, if during the timing-out of the first time delay, a value representative of said temperature is determined to be lower than said predetermined threshold value, suspending the timing-out of said first time delay and proceeding with step d); d) if said representative value is lower than said predetermined threshold value, initiating the timing-out of a second time delay (Tempo_out) during which steps a) and b) are repeated and, if during the timing-out of said second timing-out, a value representative of said temperature is determined to be higher than the predetermined threshold value, suspending the timing-out of said second time delay, resetting the measure of the timing-out of said second time delay, and proceeding with step c); e) if the first time delay has elapsed and said representative value is higher than said predetermined threshold value, preventing the automatic stoppage of the engine; f) if the second time delay has elapsed and said representative value is lower than said predetermined threshold value, authorising the automatic stoppage of the engine and resetting the measure of the timing-out of the first time delay.</p> |
