Definitions
- a flow meter 66 upstream of the particulate filter 54 and downstream of the catalyst 52 oxidation to calculate the volume flow rate of gas upstream of said filter.
- the flowmeter 66 is connected to the control unit 60 via a connection 68.
- an estimation device which would include a mathematical model of the operation of the filter.
- particle 54 which would be able to determine the volume flow upstream of the particulate filter according to data on the parameters entering the control unit 60. These data can for example include the fresh air supply flow of the engine, the flow rate of recycled gases within lines 32 and 40, and engine operating data 10.
- step 80 the values measured by the sensor 62 of the particle concentration in the exhaust gas are acquired. Then, during the following step 82, the mass M of particles present between the particulate filter 54 and the tapping of the recirculation pipe 32 is calculated. To do this, the following relationship is used:
- Q vo i represents the volume flow rate of the exhaust gases in m 3 / s measured by the sensor 66.
- the mass of particles present directly downstream of the particulate filter 54 is thus integrated by time integration.
