Definitions
- the technical field of the present invention is that of devices and methods for controlling the fuel supply for internal combustion engines.
- This type of engine is necessarily equipped with a sensor for measuring several characteristics of the fuel.
- a sensor for measuring several characteristics of the fuel.
- such a sensor can only be positioned in a place where the fuel pressure is low, i.e. between the fuel tank and the high pressure pump which is upstream of the fuel tank. fuel injector.
- a method is described in patent application FR1858049 belonging to the applicant. This process consists in taking into account the fuel consumption in the restitution of the ethanol rate to the injectors from the ethanol rate measured by the sensor. The method also takes into account the difference in volume around the sensor and around the injectors which affects the fuel transition speed. Finally, it makes it possible to detect a fuel transition based on the measurement of the ethanol content.
- the method memorizes the acquisitions of the ethanol level sensor continuously. Ethanol rate acquisitions are stored in a matrix and are returned with a delay depending on fuel consumption. Thus, the size of the matrix used must be related to the distance between the sensor and the injectors. However, the use of such matrices requires large memory resources all the more important as the sensor is far from the injector. In addition, the matrices must be stored in non-volatile memory because the history of measurements must be kept. This backup in non-volatile memory is particularly recommended when the rate varies and the computer is switched off. This case can arise when the driver, just after filling up the fuel level, moves his vehicle and parks shortly afterwards.
- the invention therefore relates to a method for determining a characteristic of a fuel to be applied to an injector of an internal combustion engine comprising a tank, at least one injector and a sensor for measuring said characteristic, inserted in a conduit connecting the tank to the at least one injector, method characterized in that:
- - data collection of said characteristic of the fuel is carried out by means of the measurement sensor over a first period of time, the average of said collected data is determined and compared with a reference value, records in a matrix said average of said collected data if this average differs by plus or minus a predetermined coefficient from a reference value of the average of the data collected or if said matrix does not include said reference value, said average of said collected data becomes the reference value,
- one carries out, for each subsequent period of time, a collection of said data of said characteristic of the fuel and of data of volume of fuel injected during each period of time, one subtracts from each volume counter associated with each average of the matrix the volume of fuel injected for each elapsed time period,
- the characteristic of a fuel to be applied to the injector being the oldest average recorded in the said matrix for which the volume counter is equal to or less than zero.
- the predetermined coefficient corresponds to the margin of error of the characteristic of the fuel to be applied to the injector that can be tolerated by the injector.
- the predetermined coefficient K is between 2% and 5%.
- volume counter associated with an average when the volume counter associated with an average is equal to or less than zero, said volume counter and said average are erased from the matrix.
- the characteristic of the fuel to be applied to an injector of an internal combustion engine corresponds to an ethanol content of the fuel.
- the characteristic of the fuel corresponds to a characteristic chosen from the group comprising the density of the fuel, the PCI of the fuel, the octane number of the fuel, the number of fuel cetane and fuel ester content.
- an estimate is made of the characteristic of the fuel to be applied to the injector between the last PRJ characteristic applied to the injector and the next characteristic of the fuel to be applied to the injector.
- said estimation consists in applying an affine law passing through the last characteristic applied and whose slope is equal to the gradient between the penultimate characteristic applied and the last characteristic applied, said affine law being applied until receiving the next characteristic to apply, or the estimate is limited by the next characteristic to apply.
- the invention also relates to an engine control unit of an internal combustion engine for implementing the method according to the invention.
- An advantage of the present invention lies in the reduction in the number of data stored in the memory of an engine control unit for example.
- Another advantage of the present invention lies in the possibility of determining a multitude of characteristics of the fuel to be applied to the injector.
- Yet another advantage lies in the reduction of the costs linked to the implementation of a method for determining a characteristic of a fuel to be applied to an injector.

- the invention relates to a method for determining a characteristic of a fuel to be applied to an injector of an internal combustion engine.
- the term "characteristic of a fuel” means the intrinsic characteristics of the fuel used for the operation of the engine. The characteristics depend on the type of fuel admissible by the engine. Mention may in particular be made of low-displacement turbocharged direct injection gasoline engines, the efficiency of which is highly optimized. It is necessary for this type of engine to know the ethanol rate with great precision.
- the term “characteristic of the fuel” means any characteristic characterizing the fuel used.
- the characteristic of the fuel may in particular correspond to the ethanol rate of the fuel to the density of the fuel, to the PCI of the fuel, to the octane number of the fuel, to the cetane number of the fuel or even to the ester rate of the fuel. .
- FIG. 1 An internal combustion engine that can be used to implement the method according to the invention.
- the engine comprises a fuel tank 1 connected to an injector 4 by a conduit 5, a characteristic measurement sensor 3 located at the level of the conduit 5 and an engine control unit 2.
- the term VTOT denotes the volume of the conduit 5 located between measurement sensor 3 and injector 4.
- the measurement sensor 3 collects data on the characteristic of the fuel passing through the conduit 5 at regular time intervals.
- the injector 4 makes it possible to inject the desired quantity of fuel into a combustion chamber.
- the engine control unit 2 makes it possible to store, process and transcribe to the injector 4 the data collected by the measurement sensor.
- Said engine control unit 2 comprises in particular a data storage means, a data processing means and an injector control means 4.
- the engine control unit 2 enables the method according to the invention to be carried out.
- the method according to the invention makes it possible to determine a characteristic of the fuel to be injected located downstream of the measurement sensor while taking into account the fuel consumption.
- Figure 2 a graph illustrating the variation of the characteristic of the fuel measured by the measurement sensor.
- the variation of the characteristic is illustrated over five time periods T x -i , Tx, Tx+i , TX+2 and T X +3.
- the duration of the time periods T x -i , T x , T x +i , T x +2 and T x +3 can vary from one time period to another and depends on the characteristic of the fuel to be measured as well as the variation of the measured characteristic.
- the duration of a period of time is generally between 1 s and 20 s, preferably 10 s.
- data P x -i of a characteristic of the fuel are collected by means of the measurement sensor over a first period of time T x -i.
- the data P x -i are collected at regular time intervals during the time period T x -i .
- the data collection interval P x -i is less than the time duration T x -i. For example, for a time duration T x -i equal to 10 s, the data P are collected every 100 ms.
- the collected data P x -i make it possible to determine the average PM x -i of the data collected P x -i during the time period T x -i.
- the average PM x -i is determined at the end of the period T x -i.
- the average PM x ⁇ i is then compared with a reference value PMCURM of the average of the data collected included in a matrix. If the average PM x -i differs by plus or minus a predetermined coefficient K from a reference value PMCURM of the average of the data collected or if the matrix does not include a reference value, the average PM x -i of the data collected P x -i is stored in the array, and becomes the PMCURI reference value.
- the volume counter CVj has an initial value equal to VTOT. Indeed, the average PMx-i of the characteristic of the fuel is determined at the level of the measurement sensor. It will then be necessary to consume the equivalent of the volume TOT situated between the measurement sensor and the injector so that the fuel comprising the mean characteristic PM x -i reaches the injector.
- the period T x follows the period T x .i
- the period T x + i follows the period T x
- the period T x +2 follows period T x+i
- period T x+ 3 follows period T x+ 2.
- the method according to the invention therefore comprises successive time periods T x , T x +i , T x +2, etc.
- Each subsequent time period T x , T x +i, T x+ 2, ... begins as soon as the previous time period T x .i , T x , T x+i , ... ends.
- a collection of data P x , P x +i, P x +2, ... of the characteristic of the fuel is carried out and volume of fuel injected Vl x , Vl x+i , Vl x+ 2, ... during the time period T x , T x +i , T x +2, ....
- the predetermined coefficient K corresponds to the margin of error of the characteristic of the fuel to be applied to the injector tolerable by the injector. This is a tolerable margin in the sense that engine operation remains optimal if an error is made in the characteristic of the fuel to be applied to the injector that does not exceed the predetermined coefficient K.
- the coefficient K is in particular a function of the characteristic of the measured fuel. It is generally between 2% and 5%, preferably 3%.
- each volume counter CVj has an initial value VTOT and is decremented at each end of period T x by the injected volume Vl x during this period.
- Each counter CVj therefore decreases and when it is equal to or less than zero, this means that the associated mean PM x has reached the injector.
- the characteristic actually seen by the injector and therefore the characteristic PRJ to be applied to the injector is the oldest reference value PMCURI recorded in said matrix for which the associated volume counter CVj is less than or equal to zero.
- the reference value PMCURI whose volume counter CVj is less than or equal to zero is deleted from the matrix.
- This PRJ value will be applied to the injector until a new counter CVj+1 becomes less than or equal to zero.
- the PMcura reference value associated with this counter will be the new PRJ+I characteristic to be applied to the injector.
- an embodiment of the method according to the invention makes it possible to estimate the variation in the characteristic of the fuel to be applied to the injector between two PRJ values.
- an estimation of the characteristic PR to be applied to the injector is carried out between the last characteristic PRJ applied to the injector and the following characteristic PRJ+I of the fuel to be applied to the injector.
- the estimation consists for example of applying an affine law passing through the last applied characteristic PRJ and whose slope is equal to the gradient between the penultimate characteristic applied P Rj .i and the last applied characteristic PRJ, said affine law being applied until 'to receive the next characteristic to be applied P R j+i, OR the estimate is limited by the next characteristic to be applied P Rj+ i.
- This estimate is made as a function of time and is made by applying, for example, an affine or linear law.
- the fuel characteristic PRJ applied to the injector will be saturated by the value of the predetermined coefficient K until the new characteristic PRJ+I to be applied is received. Or, if the new PRJ+I characteristic to be applied is received before saturation, then it will be immediately applied.
- the gradient is applied until receiving the next characteristic to be applied PRJ+I OR until the value of the applied gradient differs by more or less the coefficient K of the last characteristic PRJ applied.
- the instantaneously injected ethanol content is estimated from the previously calculated slope. From the moment the volume counter CVj has reached a negative or zero value, the estimated instantaneous ethanol content is equal to the value PRj. From this instant, the estimation of the instantaneously injected ethanol content is calculated from an affine law passing through the last applied characteristic PRJ and whose slope is equal to the previously calculated gradient. This affine law is then applied: either until the next volume counter CVj+i reaches a negative or zero value. In this case, the estimated instantaneous ethanol content is then corrected and reframed to the PMCURI+I value; or until the calculation of the estimate of the rate of ethanol injected instantaneously reaches the value PMcura+i. In this case, the estimation of the instantaneously injected ethanol content is fixed at the value PMCURI+I until the next volume counter CVj+i reaches a negative value. The method according to the invention is thus repeated every time period T x .
- FIG. 5 illustrates the development above: on the abscissa axis is the time and on the ordinate axis is the estimated ethanol concentration at the injector. Between two restitutions, a, b, c, d, the instantaneous ethanol content is estimated from the slope determined from the sample immediately received and from the previous one. This ethanol level will be saturated by the value of the next sample.
- the gradient is calculated with the measurements of sample a and sample b, and is carried over until sample c is received .
- the matrix is made up of a single value PM x .i with which a volume counter CVM of initial value VTOT is associated.
- the average PM x .i is then the reference value PMCUR because it is the last value recorded in the matrix.
- the average PM X is compared to the reference value PMCUR , here PM x .i , so as to see if they differ by plus or minus the predetermined coefficient K. According to the example, the values PMCUR and PM X do not differ by plus or minus the predetermined coefficient K, the mean PM X is therefore not integrated into the matrix.
- the volume counter CVM is decremented by the value of Vl x .
- the matrix is made up of the reference value PMCURM with which the volume counter CVM of value VTOT -Vl x is associated.
- the matrix is made up of the reference value PMCUR with which is associated the volume counter CVM of value VTOT - Vl x - Vl x+i and the previously recorded values having their volume counter also decremented by the value of VI x+1 ⁇
- the matrix is composed of the reference value PMCUR , with which is associated the volume counter CVM of value TOT - Vl x - Vl x+i - Vl x+ 2 and previously recorded values having their volume counter also decremented by the value of Vl x+ 2 , and the reference value PMCURI with which it is associated the volume counter CVj with initial value VTOT.
- the matrix is composed of the reference value PMCURM with which the volume counter is associated CVM of value VTOT - Vl x - Vl x+i - Vl x+ 2 - Vl x+ 3, of the reference value PMcuRi with which the volume counter CVj is associated and of the reference value PMcuRi+i with which it is associated with the volume counter CVj+i with initial value VTOT.
- the oldest volume counter associated with the average PM x .i (CVM) is equal to or less than zero.
- the PRJ characteristic to be applied to the injector at the end of the period T x+ 3 is therefore the PM x .i characteristic.
- FIG. 3 a flowchart illustrating the steps of the method according to an embodiment of the invention in which the characteristic of the measured fuel is the ethanol content.
- the flowchart illustrates a fast calculation loop performed for example by an integrated calculator all time periods t. In the example illustrated in FIG. 3, t is equal to 100 milliseconds.
- the illustrated flowchart also makes it possible to determine and record in the matrix the average ethanol levels and to associate a volume counter therewith.
- the ethanol level is measured at the level of the measurement sensor as well as the volume of fuel injected.
- the cumulative ethanol content and the cumulative injected fuel volume are determined.
- the cumulative ethanol rate is equal to the sum of the ethanol rate measurements measured at each time period T.
- the cumulative injected fuel volume is equal to the sum of the fuel volume measurements injected at each time period T.
- step 11 When the sum of the time periods t is greater than or equal to a predetermined time period T1, as represented in step 11, the average of the ethanol content measured during the time period T1 is calculated, in step 12. If the average ethanol rate determined at the time period T differs by plus or minus the coefficient K from the last average ethanol rate recorded in the matrix, step 13, then the average of ethanol level determined at the time period T is stored in the matrix and becomes the last average ethanol level recorded in the matrix and a volume counter of initial value VTOT is associated with it, step 14.
- steps then follow for determining and estimating the level of ethanol to be applied to the injector. These steps further comprise a slow calculation loop 15 illustrated in FIG. 4.
- FIG. 4 is a flowchart illustrating steps of the method according to one embodiment of the invention.
- This slow calculation loop also makes it possible to determine and estimate the level of ethanol to be applied to the injector.
- the volume counters associated with each average ethanol content recorded in the matrix are decremented by the value of the volume of fuel injected during the time period T 1, step 16.
- the associated ethanol rate average is then the ethanol rate average to be applied to the injector, step 18. It is then necessary to estimate the level of ethanol to be applied to the injector until the next level of ethanol to be applied to the injector is determined.
- the slope of the new estimate is determined, step 19. This slope is equal to the slope between the last mean applied to the injector and the new mean applied to the injector.
