Definitions
- the invention relates to a method for the real-time determination of the mass of particles present in a particle filter for the combustion engine of a motor vehicle. motor vehicle.
- the invention also relates to the use of this method in a management method for an engine, in particular engines operating in lean mixture.
- the heterogeneity of the combustion processes in engines operating in a lean mixture has the effect of generating carbon particles which cannot be burned efficiently by the engine. This results in the appearance of black smoke at the exhaust; characteristics of this type of engine, in particular during starting phase ⁇ and during strong acceleration.
- Compliance with future legislative standards requires the implementation of deposition systems making it possible to completely eliminate particles as well as nitrogen oxides. Currently " we have, at this.
- the means commonly used involve the creation of a gaseous environment heated to a temperature of about 600 ° C. This operation promotes self-ignition of the carbon particles retained in the filter. These are then consumed by releasing energy, which depending on conditions can be transmitted by weight to the particle bed in the filter, to the various components of the depollution system (particle filter, box and holding envelope, pipes, etc.), or else carried by the gas flow; from the engine. It is therefore important to know at all times the mass of particles contained in the filter, in particular after regeneration, so as to optimize the management of the progress of the regeneration phases and. to check the integrity of the filter. Indeed, the combustion of too large a quantity of particles can cause degradation or destruction of the filter due to the high exothermicity of this reaction.
- the mass of particles present in the filter is estimated from the measurement of the pressure drop generated by the filter, as described for example in document PR-2 774 421.
- the mass thus estimated, however, does not always have sufficient accuracy, so that the filter may be degraded.
- Document FR ⁇ : 2,657,649 presents, for different operating conditions, different regeneration strategies and regeneration control. More precisely, this document proposes to use an estimator of mass of particles contained in the filter for setting in motion or stopping the different regeneration strategies used as a function of the speed and of the operating load of the engine.
- the estimate of the mass of particles contained in the filter is determined using a difference between the mass of particles entering the filter from engine emissions and the mass of particles consumed by the combustion of particles in the filter. These masses are determined directly from maps as a function of the engine operating parameters, so that they also do not always have sufficient precision to avoid degradation of the filter.
- the invention aims to overcome these drawbacks by proposing a method for determining in real time the mass of particles present in a particle filter, which makes it possible to obtain an improvement in the precision of the calculation of the mass.
- the method according to the invention also has the advantage of requiring only one temperature sensor. inlet of the filter, which will therefore not be damaged in the event that the combustion of the particles is still too exothermic.
- the subject of the invention relates to a process for determining in real time the mass of particles present in a particle filter fitted to the exhaust line of an internal combustion engine, characterized in that the the following sequence of operations is repeated at determined time intervals: (i) the temperature T (t) of the exhaust gases at the inlet of the particle filter is measured at instant t using a sensor of temperature, (il) the operating parameters of the engine are measured at the instant t, by means of sensors, (iii) the instant at the time t, as a function of the operating parameters of the engine, is recorded on pre-established tables , the values of the following parameters: oxygen concentration [ ⁇ 2 ⁇ £ ⁇ j and nitrogen oxide concentration [NO x ⁇ t ⁇ of the exhaust gases entering the particle filter, the particle emission speed of the engine F (i) ⁇ (iv) we calculate, using the kinetic laws chemical reactions of particle combustion, at time t, the rate of combustion V (t ⁇ of the inarticulate particles in the particle filter using the following parameters: temperature T (t), oxid
- the invention also relates to the use of the method for determining in real time the mass of particles according to the invention, for; control and / or command a process for managing the regeneration of a motor vehicle particulate filter.
- the process according to ; the invention making it possible to obtain a better evaluation of the mass of particles present in the filter at each instant, it is possible to prohibit the initiation of a regeneration if the quantity of particles detected risks endangering the integrity of the filter following an excessive rise in temperature at the time of combustion.
- the determination method according to the invention is used when the temperature at the inlet of the filter is between approximately 250 ° C. and 500 ° C. Outside this temperature range, another method of mass determination can then be used, for example by using a pressure drop measurement in the â filter. particles.
- the invention also relates to the use of the method for determining in real time the mass of particles according to the invention, in a method for managing the regeneration of a particle filter of a motor vehicle, for determining a mass of threshold particles. for each operating point of a vehicle engine, below which the filter will tend to load with particles and beyond which the rate of combustion of particles in the filter will tend to increase.
- Figure 1 is a schematic representation of an engine and its exhaust line equipped with a particle filter
- Figure 2 is the plot of the mass of particles present in the filter calculated according to the method of invention ( c ) and the mass of particles measured by weighing (trip) as a function of time.
- an engine 1 is connected to a gas exhaust line; 2 fitted with a particulate filter 3. Upstream of the filter 3, with respect to the direction of circulation of the exhaust gases, an oxidation catalyst 4 is installed on the exhaust line to oxidize the nitrogen monoxide of the exhaust gases to nitrogen oxides NO * . I ; A temperature sensor 5 is provided on the exhaust line, at the input of the particle filter 3.
- the engine speed sensors 6 and the engine load sensors 7 are provided at the engine level to measure the engine speed Ne ( number of revolutions per minute) and the engine load Q corresponding to depression of the accelerator pedal.
- Pressure sensors 8 and 9 are placed respectively at the inlet and at the outlet of the particle filter 3.
- the various sensors 5 to 9 are connected to a computer 10 in which: tables, or maps, characteristics of the engine are recorded. These tables are pre-established by preliminary measurements carried out for each engine.
- the method for determining the mass of rricft ⁇ particles present at instant î in the filter is now described. This process consists of. repeat at determined time intervals ⁇ t the sequence of operations described below. (i) In a first operation, the temperature T (t) of the exhaust gases at the inlet of the particle filter is measured at instant t using the temperature sensor 5. The value obtained is recorded in the computer 10. fii) Substantially simultaneously, the operating parameters of the engine Ne and Q are measured at time t by means of the sensors 6 and 7. The measured values are also recorded in the computer 10.
- the computer 10 uses pre-established tables which are functions of the values Ne and Q to read the values of the following parameters using as inputs the values Ne and Q measured at the instant t: oxygen concentration [ ⁇ 2 (t)] and concentration nitrogen oxides; [NO x . (T)] of the exhaust az entering the filter â. particles, and particle emission speed from engine F (î). These recorded values correspond to the values at time t and are recorded in the computer 10. 1! East.
- the computer uses the parameters previously measured or recorded: temperature T ⁇ t), concentrations of nitrogen oxides ⁇ VO (t ⁇ J and oxygen [ ⁇ a (£) j as well as the mass of particles present in the filter, ⁇ ic (t- ⁇ t), obtained during the cycle of operations preceding at time t- ⁇ t
- the computer uses the kinetic laws of the chemical reactions of particle combustion, the formulas of which are These laws will be detailed later.
- the calculator calculates the mass of particles present on the filter at time t, rricft), using the mass of particles obtained during the cycle of operations preceding at time i- ⁇ i, mç (t- ⁇ t) t according to the following formula: rhcft ⁇ ⁇ nic (i- ⁇ t ⁇ + ⁇ F (t ⁇ ⁇ V (t) ⁇ * ⁇ t s (E ) where ⁇ t is the time interval between the instants t- ⁇ t and t (vi) The value of ia mass of particles rrt fi) present on the filter calculated at l 'instant t is then saved to be used as a value ; entry into the following sequence of operations at time t + ⁇ t, in particular in operations fiv) and (v).
- the mass of particles present on the filter is thus corrected in real time as a function of the operating point of the engine, which makes it possible to achieve a precision much higher than the known methods of determining the mass.
- the combustion reaction of the particles (soot) in a catalyzed particle filter is initiated according to three different and complementary processes: (1)
- the first process corresponds to the combustion of the particles by oxidation by the nitrogen oxides NO X contained in the exhaust gases or formed by the reaction of nitrogen monoxide on platinum sites present in the active phase deposited by the filter.

- the third process corresponds to the combustion of the particles by the oxygen present in the exhaust gases, initiated around 450 ⁇ 5G0 ° C, this process intensifies with the temperature and is responsible in particular for the active regeneration of the filter around 600 ° C.
- the reaction rates of these different processes can be put into kinetic equations in the following form (the rates are expressed in g / s):
