Definitions
- This invention relates to a method of tuning of engine performance, especially diesel, but which also applies to a petrol engine.
- the technical area to which it relates the invention is the adjustment of a combustion engine internal with all sensors and actuators. All the control-command laws - expressed including software - and parameters motor characterization or calibration is contained in a computer called UCE (Control Unit Electronic). We are interested here in engines diesel, which can be supercharged by a turbocharger, and whose performance is regulated by the amount of fuel injected.
- UCE Control Unit Electronic
- the fuel flow setpoint mapped based on engine speed and pedal position, can still be limited according to other criteria intended to protect the group powertrain, to increase driving pleasure avoiding filtering and jolts, and allowing special operations in the event of failures variety.
- Figure 1 which is a time diagram, summarizes this part of description.
- the part upper is a step 1 curve representing a function of a pedal first submitted to a relaxed state 2 of raised foot, then a fully depressed state 3 of foot.
- the lower part of the diagram is a family of curves all representing flows fuel injection as a function of time.
- the curve 4 is another step curve which expresses the setpoint flow deduced from curve 1 and which includes so first a weak setpoint 5, then a setpoint high 6.
- Curve 7 is a limit flow for fumes, whose value gradually increases during acceleration as the suction flow increases.
- Curve 8 is the limiting flow according to the torque, whose value decreases a little during acceleration; this curve 8 is also used for detect a transient engine speed, when the target flow 4 becomes greater than this flow of limitation for the couple. If we respect the limitations of curves 7 and 8, the flow injected would curve 9 obtained by assembling the portions of lowest curves 4, 7, and 8 at all times.
- curve 10 gives an idea of the fuel flow injected in applying the invention.
- the last part of the figure 1 illustrates the engine revving without application of the invention, based on the application of the curve 9 by means of curve 11, and curve 12 expresses the engine speed with the invention, in applying the flow of curve 10.
- the idea behind the invention is to have physical quantities which fixed the powertrain operating limits, to grasp the momentary values of these quantities physical or some of them and adjust the additional fuel injection rate during the transient regime according to said values that take these physical magnitudes.
- the invention is susceptible of numerous forms of concrete achievements according to physical quantities evaluated and criteria of limitation of fuel injection rate. His utility is greatest when the injection rate is mainly limited according to the engine torque, but it remains important when the flow is limited by other constraints and in particular by production smoke.
- the invention can be summarized as a method for adjusting engine performance diesel during transient regimes by increasing temporarily the flow of fuel injected beyond normal limits while making sure to save a state reliable engine operation while the limits are violated, adding ways to unknown motor control and flow adjustment already existing processes.
- the injection rate can be increased more strongly only in these processes, but only if the conditions of the transitional regime, expressed by reliability parameters, allow it.
- the reliability parameters of operating modes may be numerous. Some can be detected, others calculated and others still can be simply estimated. It is so in accordance with a complementary aspect of the invention of limit the additional injection rate of fuel during the transitional period, i.e. by limiting the duration of the increase in flow, either by limiting the additional energy supplied, either by taking into account the existence of transitional arrangements precedents, in order to guard against the risks that engine reliability criteria have not approached their permitted limit to this transitional regime or to precedents.
- FIG. 2 illustrates an example not limitation of a diesel powertrain on which the invention can find employment.
- the engine carries the reference 13, the electronic control unit or ECU reference 14, the accelerator pedal reference 15, and the combustion air passes successively through a air filter 16, a flow meter 17, a compressor 18, a heat exchanger 19 and a valve 20 before reach the motor 13; combustion gases leave the vehicle by successively crossing a turbine 21 and a particulate filter 22.
- the compressor 18 and the turbine 21 belong to the same turbocharger 23 whose operation can be adjusted by adjusting, as is known, the angle of closing of fins at the inlet of turbine 21 or a closing valve of a bypass gas exhaust.
- the ECU 14 allows this setting to be accomplished as well as the injection adjustment in accordance with the invention, among others.
- Sensors 26, 27 and 28 measure depressing the accelerator pedal 15, the speed of motor 13 (by a speed of rotation of the shaft of crankshaft) and the gearbox ratio 24 (by the position of the gear lever or the gear ratio rotational speeds on either side of the box).
- FIG. 3 represents the portion of ECU 14 responsible for determination of the fuel injection rate during transitional regimes.
- This view shows a certain number of cards, i.e. functions fixed to several variables recorded in the ECU 14 and which deliver an output value according to the values reached by the variables.
- a first card 25 thus determines the fuel flow setpoint (qo) based on pedal depressing values acceleration 15 and engine speed provided by sensors 26 and 27,
- a card 36 determines the limitation of flow according to the torque (qoc) of the motor in function engine speed and gearbox ratio 24 by sensors 27 and 28, and
- a third card 37 determines the limitation of injection rate for fumes (qof) using engine speed and flow of fresh air by sensors 27 and 17.
- Curves 4, 8 and 7 come respectively from the card outputs 35, 36, and 37, and curve 9 would be produced in supplying these values to selection circuits 38 and 39 which always deliver the lowest value which is simultaneously applied to them.
- selection circuits 38 and 39 in series, of which the first would receive the outputs of cards 35 and 36 and the second would receive the output of circuit 38 and the exit of the third card 37.
- Curve 9 would be obtained at the output of the second selection circuit 39 and could later be corrected by a module 40 accentuating driving pleasure and loaded by example of reducing driving jolts. The influence of this module 40, which does not belong to the invention, will however be ignored here.
- the use of the invention implies add a pair of additional cards 41 and 42 which are used during transitional regimes and express, like maps 36 and 37, limitations injection rates according to the torque (qtc) and the smoke (qtf). They are informed by the signals from the same sensors (respectively 27 and 28, and 27 and 17) and provide limiting values which reach positive input terminals of respective subtractors 43 and 44. inequalities qtc> qoc and qtf> qof are normally respected.
- the outputs of cards 36 and 37 are supplied to the negative input terminals of subtractors 43 and 44, so that these output signals expressing torque and smoke limitation increases in transient regimes and therefore injection rates additional ( ⁇ qc and ⁇ qf). These signals come add to the output signals of cards 36 and 37 in respective adders 45 and 46, and these are actually the sums coming out of these adders which are supplied to selection circuits 38 and 39.
- the signal out of selection circuits 38 and 39 therefore represents the flow q actually injected into the motor 13, i.e. curve 10.
- signals from subtractors 43 and 44 only arrive at adders 45 and 46 that after having been corrected in multipliers 47 and 48 which express the influence of powertrain reliability criteria.
- a row of curves 49 uses the signals from respective sensors measuring the states reached by parameters of reliability of the powertrain, or indications estimated in another way, by calculation or estimation, in particular in the ECU 14.
- the sensors can comprise at least some of the sensors already encountered or others.
- a possible list of the quantities used can be given by table 1, knowing that it is neither inclusive nor exclusive, each quantity making it possible to evaluate at least one reliability parameter. List of sizes Means of understanding magnitudes Duration of the transitional regime calculation Frequency of transient regimes calculation Engine speed sensor Derived from engine speed calculation Gearbox report calculation Temperature before the turbocharger turbine estimate Engine oil temperature sensor Engine oil pressure estimate Engine water temperature sensor Pressure across the particulate filter sensor Air exchanger temperature estimate Compressor outlet air temperature estimate
- Curves 49 provide a coefficient between 0 and 1 according to a function therein recorded.
- the coefficients high represent situations where functioning of the engine is perfectly reliable and where fuel injection flow increases are only not to be feared, and the low coefficients express at contrary to situations where the extreme states of engine operation are close and where it is so careful to respect the injection limits of fuel prescribed by maps 36 and 37.
- the method proposed in this embodiment includes a limitation of the increase in performance, that is to say of the additional injection rate.
- the limitation relates both to the duration of the transitional regime and to the frequency of transitional regimes.
- the gross limitation factor Kfi produced by the selection circuit 50 is delivered both to a multiplier 51 and to a divider 52. This divides a gain coefficient ki produced by a gain circuit 53 by the gross limitation factor and transmits a corrected gain coefficient to an integrator 54.
- the quantity processed by the integrator 54 is the additional injection rate according to the torque ⁇ 'qc (reduced by the overall limiting factor), that is to say the same quantity as product the multiplier 47.
- this quantity is produced by another multiplier 55. It therefore receives at an input terminal the additional injection rate (gross) according to the torque ⁇ qc and at the other terminal a limiting factor global K from multiplier 51 and which is also delivered to multipliers 47 and 48.
- the integrator 54 performs a temporal integration of this additional bit rate, and multiplies this value by the gain from the divider 52 while also taking into account an initialization value v, supplied by a second integrator 56 to which we will return.
- the integral obtained is a representation of the increase in energy which is supplied to the motor 13 since the start of the transient. It is bounded and inverted in a calculation module 57 which performs the operation (1- x / 1- energy threshold ), where x is the value of the integral and the energy threshold is a fixed value.
- a digital threshold 58 which deduces therefrom an energy limiting factor Ke which is supplied to an input terminal of the multiplier 51 and therefore serves to modify the overall limiting factor Kfi according to the additional energy which has already been supplied during this transitional regime.
- the integral is initialized to a determined value (v i ) and as long as its value is below the energy threshold, corresponding to a total quantity of fuel injected, the energy limitation factor Ke remains equal to 1.
- the integral decreases progressively towards zero.
- FIG. 4 illustrates the results obtained.
- the first time diagram which is represented again is curve 1.
- the second diagram has the reference 59 and represents the value x of the integral resulting from the integrator 54, and the third curve bears the reference 60 and represents the additional injection rate for limiting torque, from multiplier 47 or 55 ( ⁇ 'qc).
- the value of curve 59 increases fairly quickly until an energy threshold 61 is reached, which corresponds to a state of filter 58 providing a output equal to 1, and the injection rate additional 60 forms a bearing 62 at a high level.
- the filter 58 provides increasingly lower values which affect the overall limiting factor K and make decrease the injection rate fairly quickly additional 60 until it becomes zero.
- the integral 59 then takes a constant value.
- curves 63 and 64 are analogous to curves 59 and 60 and show that if the initial value of the integral is not not zero, the energy threshold 61 is reached faster, the bearing 62 is shorter, and the convergence of the flow additional injection to zero is faster. Now the area included under curve 60 or 64 is shown on additional total injection rate during transient, or total additional energy provided. So we see that the initialization value strongly influences this energy.
- Figure 5 also shows the moderating effect of the gross limiting factor Kfi from the circuit of selection 50.
- Curves 1, 59 and 60 have been copied. If a gross limiting factor less than 1 is applied, if for example it is equal to 0.5, the curves 65 and 66 would replace curves 59 and 60 in the absence of the divider 52: the integral would converge towards the same final value with greater slowness and would also reach energy threshold 62 with delay.
- level 67 of the curve 66 corresponding to level 62 of curve 60, would have a value equal to that of level 62 of curve 60 divided by gain ki, but would last longer that the bearing 62 in the same ratio, and that the curve 66 would then converge to zero, but more slowly than curve 60, which explains why the area included under curve 66 would be identical, and that the quantity of total fuel injected would be invariable.
- the gain ki produced by circuit 53 does not influence the amount of fuel injected but over time total injection. This is why the divider 52 is added.
- Figure 6 shows that the gross limitation Kfi is used to limit the amount of total fuel injected: curve 65 is replaced by curve 68 coinciding with curve 59 and therefore allows filter 58 to supply its factor of reduction without delay. Curve 67 is then replaced by curve 69, the level of which is not higher that the bearing 62 of the curve 60 and which also converges quickly towards a zero value than curve 60: the total amount of fuel injected is reduced in proportion to the gross limiting factor.
- the objective is to limit the amplitude of the increase in engine performance in transient conditions as a function of the frequency of the transient conditions.
- the signal which enters the second integrator 56 depends on a switch 75 which performs a comparison between the output signals from the cards 35 and 36 to determine whether a transient state exists now, depending on whether the setpoint of the fuel flow rates is higher. flow limitation based on torque.
- the output of the multiplier 55 that is to say the additional injection rate ⁇ 'qc, enters the second integrator 56, otherwise it is a negative constant coming from a circuit 76.
- the initialization value v i supplied to the first integrator 54 will be all the more important when significant and prolonged previous transient regimes have been recorded; their influence will decrease over time thanks to the effect of the negative constant, which will gradually decrease the initialization value produced at the output of the second integrator 56. After a sufficient duration, the output of the second integrator 56 will fall to zero (but the second integrator 56 is designed to never supply a negative value) and the energy supplied in the current transient regime will not be reduced, according to the reasoning made with regard to curves 59 and 61 of FIG. 4.
- the frequency of the transients also makes it possible to correct the gross limiting factor Kfi by introducing therein another moderating coefficient Kfr.
- FIG. 7 illustrates the effect of the frequency of the transients on the control of the motor.
- the first diagram bears the reference 79 and in fact illustrates three transient regimes similar to that of diagram 1 and separated by durations equal to their durations of existence.
- Diagram 80 illustrates the output of the first integrator 54 and shows that the energy threshold 81 is reached more and more quickly after the start of each of the transient states;
- diagram 82 illustrates the additional injection flow rate for torque limitation and shows that the total quantity of fuel supplied decreases with each new transient speed;
- diagram 83 represents the output value of the second integrator module 56 which initializes the first integrator 54 and shows in particular that it takes ever higher values with each new transient regime despite the decrease produced during their intervals;
- diagram 84 illustrates the output of memory 78 and shows that the limitation factor as a function of the frequency of the transient regimes is regularly decreasing. But it should be noted that, if the acceleration is less sensitive to each of the transients, the system tends to converge towards a state where an additional injection flow is still delivered to the engine, even if it is smaller than at the first transient.
- the invention relates, in all of its variants, to a method for adjusting the performance of an engine in operation, comprising a determination of the target fuel injection rate, a calculation of at least one limit of fuel injection rate as a function of at least one engine operating criterion and, when a transient state of acceleration is detected, a calculation of an additional fuel flow temporarily authorized beyond the limit ( ⁇ qc, ⁇ qf), characterized in that the additional flow is limited ( ⁇ 'qc, ⁇ 'qf) according to at least one reliability parameter of the engine.
- Detection of a transient regime can depend on a more complicated criterion than the one we have reported.
- the pedal sensor acceleration 26 can power a module 85 differentiator, and a driving style module 86 is associated with it.
- a comparator 87 detects the depressing speed of pedal 15 and determine whether it is greater than a threshold provided by the module driving style 86 and which can be adjusted according to the driver request. If the driving speed is greater than the threshold, it is detected by the comparator 87 that a transitional regime exists; the outputs of comparator modules 75 and 87 then all contribute two at the detection of the transient state by means of a logic gate 88, AND for example.

on notera que pour le calcul des coefficients élémentaires Ke et Kfr qui, comme le coefficient de limitation brut Kfi, sont compris entre 0 et 1, on utilise des estimations de débit supplémentaire d'injection total d'après un seul des débits supplémentaires calculés, ici d'après le couple moteur (Δ'qc), alors même qu'un autre débit supplémentaire, Δ'qf par exemple peut déterminer le débit d'injection total q. On se contente donc d'une estimation approchée, dont l'expérience a cependant montré la validité.
