Definitions
- the present invention relates to a method for generating a synchronization signal, representative of the unfolding of the operating cycle of a four-stroke internal combustion engine, of the multicylinder type, the expansion phases of each cylinder, during which the combustions take place. , occur at angular positions of the distinct crankshaft rotation motion as is the case for odd-numbered four-stroke engines.
- the invention more specifically relates to a method for generating a signal for locating a predetermined time of the cycle such as the passage to the High Admission Dead Point or to the Low Admission Dead Point.
- the performance of an engine as well as the control of the emission of pollutants are related to the various control methods governing the operation of the engine. These methods, for example fuel injection or ignition, require precise knowledge of the current thermodynamic cycle in the engine cylinders.
- the document FR 2 441 829 proposes a means of detecting information on the thermodynamic cycle of the cylinders by locating, on a target secured to the crankshaft, the zones of angular position corresponding to a given phase of the stroke of the different pistons.
- the target consists of a disc having locating elements disposed along its periphery, such as teeth of different lengths.
- a fixed receiving member detects these registration elements and generates electrical pulses for producing a signal identifying the passage to the top dead center position of a determined piston.
- the publication FR 2 749 885 proposes a simple and effective method of identification which does not require any specific position sensor apart from that which serves to locate the angular position of the crankshaft.
- This method uses a timing signal that is generated from the combustion conditions in each of the cylinders of a four-stroke and four-cylinder engine, and information transmitted by the crankshaft sensor.
- At least one factor governing the combustion in a given reference cylinder is modified so as to cause an alteration controlled combustion.
- This alteration of the combustion in the reference cylinder is then detected thanks to a quantity Cg developed from the information from the crankshaft position sensor of the engine, thus making it possible to synchronize the passages at the Top Dead Center Admission of the engine cylinders with the Top Dead Center signal of the crankshaft sensor.
- this invention requires a degradation of the combustion of the engine altering its operation and increasing pollutant emissions.
- the present invention therefore aims to overcome the drawbacks of the known tracking systems in the case of a four-stroke engine comprising a number of odd cylinders, by proposing an improved registration method, requiring no specific position sensor outside of that which serves to locate the angular position of the crankshaft, and does not affect the operation of the engine.
- the invention proposes a method for producing a synchronization signal of an odd-numbered four-stroke internal combustion engine by an electronic control system, the synchronization signal enabling the identification of a predetermined instant in the engine.
- thermodynamic cycle of each of the cylinders of the engine is determined from a signal identifying a determined position of each cylinder, and a representation signal of a magnitude representative of the kinematics of the crankshaft generated by each combustion, both generated from the information of a crankshaft position sensor of the engine the method comprising the following steps:
- the signal representative of a cylinder during a first revolution of the cycle can be compared to the signal representative of the cylinder during a second cycle turn, so as to know the phase of the first turn, and reset the sync signal if the phasing was wrong.
- the representative signal may be a representation of the gas pair or a harmonic representation of the tooth duration.
- Figure 1 is a diagram of the engine control device incorporating the method of the invention
- Fig. 2 is a diagram detailing the steps of an injection method using the synchronization signal of the invention
- FIG. 3 represents the phasing of the NOCYL synchronization signal according to the invention.
- a four-stroke internal combustion engine for a motor vehicle comprises three cylinders (C1, C2, C3) each comprising an electronically controlled multipoint type fuel injection device. whereby each cylinder is supplied with fuel from a specific electro-injector.
- each electro-injector 5 is controlled by the electronic engine control system 7, which adjusts the amount of fuel injected and the injection time (Inj) in the cycle according to the operating conditions of the engine, so that precisely slaving the richness of the air-fuel fuel mixture admitted into the cylinders to a predetermined target value.
- the electronic engine control system 7 conventionally comprises a microprocessor (CPU), random access memories (RAM), read only memories (ROM), as well as analog-digital converters (A / D), and various input and output interfaces. exits.
- CPU central processing unit
- RAM random access memories
- ROM read only memories
- a / D analog-digital converters
- the microprocessor includes electronic circuitry and appropriate software (10, 222, 223, 224) for processing signals from suitable sensors, determining engine states, and implementing predefined operations to generate control signals at the desired destination. in particular injectors so as to better manage the combustion conditions in the engine cylinders.
- the electronic engine control system 7 is more particularly intended to operate a fuel injection of separately triggering each injector 5 so that the fuel injection is completed before the opening of the corresponding intake valve or valves.
- crankshaft sensor 22 of the type for example magneto-reluctant, is fixedly mounted on the motor housing to be positioned in front of a measuring ring 12 integral with the steering wheel. inertia attached to one end of the crankshaft.
- This ring 12 is provided at its periphery with a succession of identical teeth and troughs with the exception of a tooth which has been removed so as to define an absolute reference point making it possible to deduce the moment of passage to the Top Dead Center. a given reference cylinder, in this case the cylinder C1.
- the sensor 22 delivers a signal Dn corresponding to the running of the teeth of the ring gear 12, which signal after treatment by a processing device 10 makes it possible to generate a PMH signal every 120 ° of crankshaft rotation making it possible to locate the passages at Top Dead Center alternately.
- the processing device 10 of the signal Dn emitted by the sensor 22 also makes it possible to measure the running time of the teeth of the ring gear 12, and thus to obtain the running speed and the instantaneous rotation speed N of the motor.
- the signal Dn is further processed by the device 10 to produce a signal (Cg, Bn) which is a representation of a magnitude representative of the kinematics of the crankshaft.
- this quantity can define a representation of the estimated gas torque generated by each of the combustions.
- the value of the signal Cg for each combustion of the gas mixture in the engine cylinders is obtained in particular from the analysis of the signal Dn delivered by the fixed sensor 22 observing the toothed wheel 12 integral with the crankshaft.
- the signal is not used directly, for example by taking the instantaneous speed of rotation, because the presence of measurement noise or the lack of realization of the teeth would generate significant errors due to inaccuracies of the signal and make the process less robust .
- a harmonic decomposition analysis makes it possible to eliminate these defects.
- [Cgaz, 0] u is the average gas torque produced by at least one combustion in a cylinder u during a combustion cycle
- ⁇ 1 is a function of ⁇ and / or ®k respectively duration and speed of passage of the pattern Dk in front of the sensor
- a ° ' 1 is a variable dependent on at least one engine operating parameter
- i is an index that counts the linear combinations of functions
- ru respectively denote the number of the first pattern and the number of the last pattern perceived by the position sensor during the combustion of the cylinder u, or the last virtual pattern developed from the sensor signal, defining the angular window for analyzing the engine torque associated with the combustion of the cylinder u.
- other quantities representative of the kinematics of the crankshaft can be defined as harmonic components representative of the speed or the duration of travel of the teeth of the crown.
- the tooth duration is the duration measured between two teeth of the target.
- the torque estimate is will do by observing the speed of rotation between 0 and 240 ° or a angular window generally encompassing 0-180 ° of the combustion phase of the cylinder C1.
- the combustion time associated with the cylinder C3 is between 240 ° and 420 °, the observation will be made on the angular range between 240 ° and 480 °.
- the combustion time is between 480 ° and 660 ° the range of observation of the engine speed will be around 480 and 720 °.
- the location of the predetermined moment in the unfolding of the engine cycle for phasing the injection of each of the cylinders which in the example illustrated is the passage to the High Admission Dead Point, or any other time that can serve as a reference, is operated from a synchronization signal NOCYL synchronized with the PMH signal providing the identification of the passage to the top dead center of each cylinder in a circuit 224.
- NOCYL synchronization signal can be used which alone or in combination with a signal from a counter of the number of Dead Center High cylinders scrolling past the position sensor to determine the phase of the combustion cycle for each cylinder.
- the NOCYL signal represented in FIG. 3 does not require comparison with other signals and it provides all the sets of predetermined moments in the course of the motor cycle for phasing the injection or the ignition of each of the cylinders for all the cylinders of the engine.
- the signal NOCYL provides the passage to the High Admission Dead Point and the passage to the Top Dead Point of all the cylinders at the time of the change of value. A single signal is then sufficient to synchronize all the actuators of the motor control.
- the PMH signal indicates each passage to the Top Dead Center of the engine cylinders by the generation of a rising or falling edge.
- the signal NOCYL is arbitrarily initialized to 0 at the first detection of the transition to the Top Dead Center of the reference cylinder (C1 in this example) which is therefore considered arbitrarily as a High Admission Dead Point, then it is incremented.
- the NOCYL signal is constructed by incrementing a modulo 6 counter each time the High Dead Point of the PMH signal is passed.
- NOCYL signal provides a unique reference for all motor cycles that allows a phasing system 222 to synchronize any engine control process (ignition, injection, control actuators ).
- the estimation of the torque Cg by the torque estimator described above makes it possible to know if the synchronization is the right one. Indeed, if the injection and ignition are poorly phased, the engine can not produce torque because combustion is done during admission.
- a processing unit 223 compares the estimated value Cg with a reference value or reference value Cc conventionally developed by the engine control during the start-up phase to estimate whether the phasing is correct. The condition to check is then: ⁇ is a positive torque value that can be constant or mapped according to the motor control parameters in order to ensure the robustness of the criterion E1 by limiting the taking into account of the noise of the signals.
- the strategy then considers that the Top Dead Point initially detected was the High Dead Point, the NOCYL signal is then reset in the circuit 224 by an Init signal of C3 signal processing circuit 223. The phasing is now correct, the condition E1 must then be verified. If this is not the case, there is a failure in the injection or ignition system or at the engine level.
- a second embodiment of the invention makes it possible to operate in the case of a startup with lost spark.
- the ignition of the engine is controlled in "lost spark" mode. previously described to ensure the starting and operation of the engine including when the phasing engine is not identified.
- the torque estimation is done by observing the acyclic speed or instantaneous rotation times of the crankshaft of the engine over an angular range directly related to the supposed phasing of the engine which theoretically covers the combustion phases of the three cylinders.
- the combustion time of the cylinder C1 is between 0 ° and 180 °
- the estimation of the torque will be done by observing the speed of rotation between 0 and 240 ° or an angular window generally encompassing 0-180 ° of the combustion phase of the cylinder C1.
- the combustion time associated with cylinder C3 is between 240 ° and 420 °, the observation of acyclism will be on the angular range between 240 ° and 480 °.
- the combustion time is between 480 ° and 660 °
- the observation range of the engine speed will be around 480 and 720 °.
- the observation of the estimated torque Cg of the combustion of the cylinder C1 will be one revolution later, ie between 360 ° and 600 ° instead of the range 0-240 °. Therefore, it is no longer the combustion of the cylinder C1 which is observed but the end of the combustion of the cylinder C3 and the beginning of the combustion of the cylinder C2, and the estimated torque Cg in this example for these combustion moments of the cylinder C2 and C3 is negative.
- a first variant of the second embodiment consists in estimating the gas torque Cg for all the engine revolutions.
- the torque of cylinder C1 thus estimated in the first round Cg1_1 is recorded and compared with a new observation of the pair Cg1_2 of the cylinder C1 in the next turn.
- the synchronization can thus be performed according to the result of the comparison.
- a second variant consists in comparing the value of the estimated torque Cg for a given cylinder with respect to a set torque value Cc according to the following relationship:
- the signal NOCYL does not correspond to the thermodynamic cycle of each cylinder, the value of the estimated torque Cg is then significantly less than the torque value of Setpoint Cc and vice versa.
- the Delta offset is a torque value that can be a constant or derived from a map dependent on the Engine Speed and / or Torque, and which makes it possible to freeze a threshold necessary for the comparison in order to exclude any risk of false synchronization due to noise in the signals.
- the basic methods and variants of the first and second embodiments can be made reliable by limiting the errors due to disturbances or noise of the signals for example by summing the torque estimates Cg.
- the error limitation can also be carried out by filtering, for example carried out according to a filtering of the first or second order or any other filter making it possible to filter the noise of the measurements and estimates and thus rendering the result of the comparisons more robust.
- F n (Xn) aX n + ( ⁇ _a) F n4 with 0 ⁇ ⁇ ⁇ 1
- a representation of a magnitude representative of the kinematics of the crankshaft other than the torque can be used.
- a third embodiment of the invention uses a harmonic analysis representative of either the tooth duration or the instantaneous rotation speed of the crankshaft.
- this embodiment consists in studying the harmonic component of order n of the rotational speed or preferably of the tooth duration established from the signal Dn.
- the harmonic component of Bn will here be calculated using the cosine harmonic function, but the method can be adapted for any other harmonic function for example using a trapezoid function or other more complex function.
- This component Bn is a simplified representation based on the relationship of the estimated torque (Cg) above, taking appropriate coefficients.
- the harmonic component of the tooth duration can be established by the following relation:
- the synchronization can thus be performed according to the result of the comparison as in the previous embodiments.
- This embodiment is robust to target defects, since it compares two quantities potentially biased in the same way by the target defect, the calculations of Bn on the two PMH of the cylinder originating from durations measured on the same angular portions of the target of the crown.
- the harmonic component established in the first round will be decomposed into a sum of the harmonic component representative of the thermodynamic cycle during the first round and a harmonic component representative of the target defects.
- the harmonic component established in the second round will be decomposed into a sum of the harmonic component representative of the thermodynamic cycle during the second round and a harmonic component representative of the target defects that is the same as in the first round. Therefore, a comparison of the harmonic component established in the first round and that established in the second round will eliminate the representative component of the target defects.
- the NOCYL signal is reset by changing the synchronization hypothesis (shift of one revolution of the synchronization). This reset can be done on the PMH of the reference cylinder or on any PMH of any cylinder. The synchronization must then be confirmed again by a method according to one of the previously described embodiments before establishing the normal operation of the engine with sequential ignition.
- the invention advantageously makes it possible to synchronize the thermodynamic cycle of each cylinder without modifying operating parameters of the engine and without altering the operation of the engine.
