Definitions
- the invention relates to a method of early triggering a regeneration of a particulate filter as a function of the engine water temperature of a motor vehicle.
- depollution means which may comprise a set of catalysts transforming the toxic constituents of the exhaust gases. exhaust, such as carbon monoxide, unburned hydrocarbons or oxides of nitrogen, into less toxic elements such as water vapor and carbon dioxide.
- These means of pollution also include, especially for diesel engines but also for gasoline engines or hybrid engines in accordance with the new standards, a particulate filter that traps particles from combustion in the cylinders.
- the particles mainly in the form of soot, accumulate in the particulate filter so that only purified gases are discharged.
- a particulate filter should be cleaned regularly to remove any particles that have accumulated from inside. This filter cleaning operation is called filter regeneration.
- a regeneration of a particulate filter is based on soot combustion by raising the temperature of the particulate filter to the temperature at which the carbon particles burn.
- the most conventional method for regenerating a particulate filter requires post injection and particular engine settings.
- the post injection makes it possible to inject an additional quantity of fuel into at least one of the cylinders.
- the fuel thus injected late ignites by producing an increase in temperature of the exhaust gas.
- One of the negative impacts of post injection on the engine is the phenomenon of dilution which results in the presence of fuel in the engine oil. Indeed, the fuel injected late and does not burn in the combustion chamber can cause the formation of a liquid fuel film on the inner walls of the engine cylinders. This unburned fuel can then pass under a piston and mix with the engine lubricating oil. Such dilution adversely affects the lubricating properties of the oil and can be detrimental to engine reliability, resulting in premature wear or at least degrading the lubricating qualities of the engine oil.
- this second so-called desired engine cooling water temperature is generally not less than 60 ° C. and can vary between 60 and 90 ° C.
- This cracking is mainly due to the excessive heat released by too many particles accumulated in the filter and being burned together. Such cracking may result in destruction of the particulate filter.
- the first and second cooling water temperatures of the engine are therefore carefully monitored and even become a condition for triggering regeneration. of the filter.
- This regeneration is advantageously triggered by a particle filter supervisor during the rolling of the vehicle.
- Such a supervisor calculates the regeneration opportunities of the particle filter according to measured data.
- These data measured in particular by means of particle filter control sensors, may concern the mass of particles in the particulate filter, a pressure difference across the particle filter, the combustion mode, the current dilution, the outside temperature.
- a regeneration is triggered.
- Another data that can be taken into account by the particle filter supervisor is the mileage traveled since the last regeneration.
- the desired regeneration temperature advantageously above 60 ° C. as a function of the soot mass inside the estimated particulate filter.
- this desired regeneration temperature can then go down and reach the first minimum temperature of regeneration water, advantageously 30 ° C.
- the problem of the present invention is to index the minimum cooling water temperature for the beginning of a regeneration on an indicator taking into account the road behavior of the motorist in order to anticipate a particle filter overload, very often also related to the type of running of the motor vehicle.
- an early triggering process of a regeneration of a particulate filter present in the exhaust line of a motor vehicle according to a temperature threshold value characterized in that the threshold value is calculated according to the driving conditions of the vehicle, one or more parameters which can be taken individually or in combination to represent the driving conditions:
- said threshold value (Water Threshold) of water temperature is therefore between said minimum temperature value (Tmin) and said desired temperature value (Tsouh) of water (up to being equal to one of these temperatures).
- the technical effect is to make the rolling of the automobile depend on the threshold of the triggering water temperature of a regeneration then necessary. This makes it possible to adapt the threshold to each behavior of the motorist. It is thus obtained that the regenerations triggered with anticipation are as complete as possible, avoiding their interruption by a shutdown of the vehicle engine.
- the temperature threshold value is calculated as a function of the running time and the distance traveled by the vehicle, two pairs of rolling time and distance traveled values are determined, the first pair of values being determined. corresponding to obtaining a minimum water temperature below which a regeneration is not allowed and the second pair of values corresponding to obtaining a desired water temperature at or above which triggering a regeneration is preferred.
- the first and second pairs of values in respective correspondence with the minimum temperature value and the desired temperature value are obtained by mapping.
- n vehicle journeys with for each of these n trips a specific pair of running time and distance traveled, it is calculated an average of n running times and an average of n distances traveled.
- the threshold value of water temperature being calculated according to the following equations:
- MD being the average of the n distances traveled and Mt the average of n running times
- Tmin the minimum water temperature and Tsouh the desired water temperature
- D1 and t1 being respectively the distance and duration of the first pair and D2 and t2 the distance and duration of the second pair.
- the temperature threshold values and the minimum temperature and desired temperature values are corrected as a function of the mass of particles inside the particle filter, these temperature values being lowered when the mass of the particles increases.
- the temperature-corrected threshold values forming a curve as a function of the mass of particles between the curve of the minimum temperature values and the curve of the desired temperature values.
- a critical mass of particles inside the filter is defined for which a regeneration of the filter even at a predetermined minimum temperature value is imperative, this predetermined minimum temperature value being reached by the curve of the values of the minimum temperature for a predetermined mass of particles smaller than the critical mass.
- the curve of the temperature-corrected threshold values oscillates between the curve of the minimum temperature values and the curve of the desired temperature values, the curve of the desired temperature values meeting the curve of the minimum temperature values from the critical mass. of particles reached.
- the curve of the threshold values of temperature goes down when the rolling of the vehicle in duration and average distances becomes shorter and goes back up when this rolling becomes longer.
- the outside temperature thus measured being used to determine a water-corrected minimum temperature value as a function of the outside temperature, this minimum temperature value corrected from the outside temperature.
- water being compared with the temperature-corrected threshold value calculated as a function of the mass of particles, the minimum value between the corrected temperature threshold value and the water-corrected temperature value being taken as a new temperature threshold value to be compared to the measured or estimated water temperature value.
- FIG. 1 is a schematic representation of the steps of the determination of a temperature threshold value according to an embodiment of a method of early triggering of a regeneration according to the present invention
- FIG. 2 is a schematic representation of minimum cooling water temperature curves as a function of the running time and the distance traveled by the motor vehicle
- FIG. 3 shows three temperature curves as a function of the charge of the particulate particle filter, the curve of the corrected temperature threshold being interposed between the desired temperature curve of water and the minimum temperature curve of water for a given temperature. regeneration, the curve of the corrected temperature threshold being obtained by a method of early initiation of a regeneration according to the present invention,
- FIG. 4 shows a minimum temperature curve of regeneration water as a function of the charge of the particulate filter, this curve being obtained by a method of triggering a regeneration according to the state of the art
- FIG. 5 shows a schematic representation of the steps of the determination of a temperature threshold value according to a variant of the method of early triggering of a regeneration according to the present invention, the outside temperature being taken into account in this variant.
- the present invention relates to a method of early triggering a regeneration of a particulate filter present in the exhaust line of a motor vehicle. Such a method can be implemented by elements embedded in the engine computer or in the particle filter supervisor present in the motor vehicle. The main steps of the method of early triggering of a regeneration are illustrated in Figure 1.
- the anticipated triggering method provides for determining a threshold temperature threshold SeuilTeau water cooling engine for which or above which a regeneration RG of the particulate filter can be triggered.
- the method takes into account for the calculation of this threshold value Threshold Water temperature water a minimum temperature value Tmin of water below which a regeneration RG is not allowed and a desired temperature value Tsouh of water to which or above which the triggering of a regeneration RG is preferred.
- the threshold threshold WaterSeal is calculated according to the vehicle running conditions, one or more parameters can be taken individually or in combination to represent the driving conditions: the duration of driving taken in combination with the distance traveled by the vehicle, the average speed of the vehicle, the proportion of idling time or the proportion of time with a speed of travel below a predetermined speed, engine speed or torque, the number of feet per minute of the driver, the average of the cooling water temperature over the duration of the engine running.
- FIG. 2 shows the obtaining of minimum cooling water temperature curves for triggering a regeneration as a function of the running time t on the ordinate and the distance D traveled on the abscissa.
- Such curves can be obtained by mapping.
- the minimum cooling water temperature curves can be of the hyperbolic type. Indeed, the less the vehicle rolls, so with a rolling time t and a distance D traveled low, the lower the threshold value of minimum water temperature must be reduced to have the time to regenerate the particle filter in case of launch of a regeneration.
- the scale on the right is the temperature scale of 35 to 90 ° C.
- a first pair of distances D1 and of short duration t1 is defined which imposes all the scenarios below which it is desired for the particulate filter to regenerate from the minimum temperature of water. for a regeneration, for example 30 ° C in Figure 2. This temperature is the minimum temperature to perform a regeneration is called Tmin. Below this temperature Tmin, no regeneration is performed.
- the threshold value SeuilTeau cooling water temperature is calculated in block 1 the threshold value SeuilTeau cooling water temperature, this according to the distances D and durations t.
- the distance D and the duration t used for this calculation are advantageously respectively the respective mean of the distances MD and the durations Mt on n motions of the motor vehicle, the averages MD and Mt being calculated respectively in the blocks 2 and 3.
- the threshold value SeuilTeau cooling water temperature is calculated according to the following equations:
- MD represents the average distance of the last n trips of the vehicle
- Mt represents the average duration of the last n trips of the vehicle
- Tmin the minimum water temperature and Tsouh the desired water temperature
- D1, t1; D2, t2 having previously been defined as the respective distance and duration of the first and second pairs of distance and duration.
- threshold ThresholdTemperature water This is done in blocks 4, 5 and 6 shown in FIG. In block 5 it is the desired temperature value Tsouh of water, in block 4 it is the minimum temperature value Tmin of water and in block 6 it is the threshold value Threshold Water of the temperature of water which are respectively corrected, the latter giving the threshold value corrected SeuilTeau cor.
- any other form of correction may also be possible, in particular as a function of another parameter than the estimated mass M of particles in the filter.
- this threshold value corrected SeuilTeau cor is less than the measured or estimated water water value, a regeneration RG can be triggered if necessary.
- FIG. 3 shows the respective temperature curves Tsouh, Threshold Water cor and Tmin as a function of the charge of the particulate filter in soot particles, these values having been corrected as a function of the mass M of particles in the filter.
- the threshold values corrected SeuilTeau cor of water temperature as well as the minimum temperature values Tmin and desired Tsouh have been corrected according to the mass M of particles inside the particulate filter, these temperature values. being lowered when the mass M of the particles increases.
- the threshold values corrected Threshold Water coral temperature form a curve as a function of the mass M of particles between the curve of the minimum temperature values Tmin and the curve of the desired temperature values Tsouh, the latter being above the curve of Threshold values corrected Threshold Water cor.
- this critical mass Me is set at 30 g, which is not limiting. As soon as this mass Me is obtained, a regeneration is triggered even when the water temperature is equal to the minimum water temperature, in this figure for example 30 ° C.
- the minimum regeneration temperature Tmin et tech was the minimum temperature desired to perform a regeneration, in this figure for example 60 ° C.
- the temperature of this minimum temperature Tmin et tech regeneration falls below the desired temperature to trigger a regeneration from the accumulation of a predetermined limit mass Ml, less than the critical mass Me, this predetermined limit mass Ml being by example of 20g to this figure.
- the curve of this minimum temperature Tmin et tech then reaches the minimum temperature of water during the accumulation of the critical mass Me in particles.
- the predetermined mass Ml, accumulated in the filter may be the largest accumulated mass value judged not to present a further danger for perform a regeneration but can become if the mass continues to increase, especially up to the critical mass Me, without regeneration.
- the minimum temperature value Tmin predetermined to perform a regeneration is reached from the accumulation of a mass of particles equal to the lower limit mass Ml to the critical mass Me by the curve of the minimum temperature values.
- the intermediate curve of threshold values corrected Threshold Water cor water temperature shows the evolution of the value threshold corrected Threshold Water coral of the water temperature according to the particle filter loading and the way of driving of the motorist.
- This curve threshold values corrected SeuilTeau water temperature cor descends when the driving of the motorist, in terms of duration and average distance of travel, becomes shorter. Conversely, this curve rises when the rolling becomes longer, while remaining in an intermediate zone between the minimum temperature curves Tmin and desired Tsouh water.
- the curve of the threshold values corrected SeuilTeau horn of temperature oscillates between the curve of the minimum temperature values Tmin and the curve of the desired temperature values Tsouh, the curve of the desired temperature values Tsouh meeting the curve of the minimum temperature values Tmin from the critical mass Me of particles reached.
- FIG. 5 A variant of the method according to the invention is shown in FIG. 5. Such a variant makes it possible to refine the triggering of the regenerations, during prolonged uses of the vehicle in very cold conditions, for example between -30 ° C. and 0 ° C. ° C, as may be the case during the winter months in Northern Europe.
- the external temperature Text thus measured serves to determine a minimum temperature value corrected Tmin of water as a function of the external temperature Text.
- This corrected minimum temperature value Tmin of water is then compared with the threshold value corrected Threshold Water coral temperature, this threshold threshold corrected SeuilTeau cor having been previously corrected as a function of the mass M of particles.
- the minimum value between the threshold value corrected SeuilTeau horn of temperature and the corrected temperature value Tmin horn of water is then taken as a new temperature threshold value and is then compared to the measured value. or estimated water temperature, similar to what was described with reference to Figure 1.
- Such a correction is based on the observation that, under very cold outside temperature conditions, the engine of the vehicle has difficulty heating its water, the driver does not otherwise change his driving habits, estimated in duration and average distances.
- Another of the main advantages of the present invention in all its embodiments, is that the anticipation of certain regenerations with a cooler cooling water temperature, even without overloading the particulate filter, makes it possible to gain engine dilution. Indeed, engines are often limited to about 10% dilution overall and regeneration in the city can be responsible up to 1% dilution for the engine.
