METHOD FOR MANUALLY RENEWING PARTICULATE FILTER

摘要

The present invention pertains to a method for renewing a particulate filter (6) by means of the heat of reaction when manual renewing of the particular filter (6) is started with a vehicle in a stopped state, an exhaust pathway is restricted by means of an exhaust brake (14), as a result, engine load is increased and the amount of fuel injection is increased, thereby increasing the temperature of exhaust gas (3), after which the addition of fuel by means of post injection by a fuel injection device (10) is started, and the added fuel is subjected to an oxidation reaction on an oxidation catalyst (5), wherein it is determined whether or not the amount of fuel injection after starting manual renewing exceeds a baseline value, and only when the amount of fuel injection is exceeding the baseline value, the restriction of the exhaust pathway by the exhaust brake (14) is disengaged when the exhaust temperature at the entrance to the particular filter (6) is at least a baseline temperature.
