All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A system for assisting the regeneration of depollution means integrated in an exhaust line of a motor vehicle diesel engine, in which the engine is associated with a turbocharger and with common rail feed means for injecting fuel into the cylinders of the engine in at least one post-injection, and adapted to implement, at constant torque, at least two regeneration strategies at a first level and at a second level, depending on different engine operation control parameters, in order to obtain different temperature levels in the exhaust line, the temperature level corresponding to the second level strategy being higher than the temperature level corresponding to the first level, the system including acquisition means for acquiring the temperature level in the exhaust line, comparator means for comparing said temperature level with a safety threshold value for the turbine of the turbocharger so that in the event of said threshold value being exceeded while applying the second level strategy, the feed means are controlled so as to regulate at least one of the engine operation control parameters progressively so as to reduce the temperature level in the exhaust line, and if said temperature level does not drop below the threshold value at the end of a predetermined first time period, the feed means are controlled to switch over to the first level strategy, and if the temperature level in the exhaust line still does not drop below the safety threshold value at the end of a second time period, the feed means are controlled to stop the regeneration strategy.
