| 摘要 |
<p>The invention relates to a method for controlling the operation of a reciprocating engine such as a diesel engine and the exhaust line thereof comprising means for controlling the operation of the engine, a particle filter, a monitoring means for monitoring the operation of the particle filter, an oxidation catalyst, an SCR catalyst placed upstream of the particle filter, and means for introducing NH3 upstream of the SCR catalyst. Said method is characterised in that, when the FAP monitor decides to launch a regeneration of the particle filter, the information is transmitted to the means for controlling the operation of the engine, which go into post-injection mode, and to means for monitoring the operation of the SCR catalyst, and in that the post-injection of fuel and the quantity of NH3 injected are modulated in such a way as to compensate for the heat loss of the exhaust gases in the SCR catalyst, using the heat dissipated by the reactions on the SCR catalyst. The invention also relates to an exhaust line for carrying out said method, and to a suitably equipped vehicle.</p> |
