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 invention relates to a system for estimating the mass of particles stored in a particle filter (2) mounted in the exhaust line (6) of an internal combustion engine (3) of a motor vehicle, including a means (7, 8, 15) for measuring a differential pressure across the terminals of the particle filter, a first estimation means (15) for estimating a differential particle flow across the terminals of the particle filter, a second estimation means (15) for estimating a differential pressure across the terminals of the particle filter, and a third estimation means (17) for estimating the mass of particles stored in the particle filter (2) according to the sum of the differential particle flow and a deviation calculated between the estimation and the measurement of the differential pressure.

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.
