| 摘要 |
The invention relates to a method for regenerating a particle filter on the exhaust line of an internal combustion engine, in which fuel is injected into the exhaust tube upstream of an oxidation catalyst which is disposed upstream of the particle filter. The invention is characterised in that during regeneration: the injection of fuel into the exhaust tube is interrupted when the operation of the engine enters a critical zone (S2) defined by maximum load and speed limit values; the injection of fuel is re-established when the operation of the engine returns to the non-critical zone (S1); and, during the transient operating phases between the two zones (S1, S2), the volume flow rate of the exhaust gases is measured and, as a function of said measurement, the fuel injection rate is reduced or the fuel injection is deferred. |
