摘要： The invention relates to a method for determining the amount of regeneration fuel to be injected in the exhaust line (11) of a vehicle equipped with a particle filter (FAP) (12), an oxidation catalyst (DOC) (13) and at least one exhaust injector (14) in order to regenerate the FAP, characterised in that it comprises: determining a set-point amount of regeneration fuel to be injected into the exhaust line by the exhaust injector; determining from said measures a measured exothermal parameter of the DOC; determining by modelling a modelled exothermal parameter of the DOC; making a comparison between the data derived from the measured exothermal parameter and the data derived from the modelled exothermal parameter; and correcting the set-point according to the comparison.

摘要： The method for regenerating a particulate filter (4) in the exhaust system (3) of a combustion engine (1) involves the following steps: (a) every time the combustion engine is started, a parameter representative of the condition of the combustion engine and/or of the exhaust system is measured, (b) when the measured parameter reveals that the engine and/or the exhaust system are cold, the parameter representative of the mass of accumulated soot measured before the engine was last turned off is frozen, (c) the deviation between the frozen mass parameter and the parameter representative of the mass measured at time t is continuously determined, and (d) when the deviation has been resolved by convergence, it is added to the frozen mass parameter and the resulting corrected value is used in the ongoing regeneration process.

摘要： The invention concerns a method for obtaining fuel-loaded exhaust gases by late and/or delayed injection(s) of fuel into a Diesel engine combustion chamber (12) of a motor vehicle (V) provided with an automatic gearbox (16) robotized or with constant torque variation. The invention is characterized in that the laws defining the reduction ratio of the gearbox (16) are modified to limit dilution of the fuel in the oil present in the combustion chamber.

摘要： A particle filter regeneration control method involving filter inlet temperature control, characterised in that said control includes a correction dependent on a measurement of the mass flow rate of the exhaust gases, as determined on the basis of a measurement of the total injected diesel fuel flow rate and the intake air flow rate.
