Definitions

  • the present invention relates to a method synchronization of the electronic system control of an internal combustion engine four-stroke type twin cylinder and injection multi-point electronic fuel.
  • the invention relates more precisely to a process capable of generating a synchronization signal allowing to follow the progress of the functioning (succession of different times engine) in each of the engine cylinders, this synchronization signal for identification of a predetermined instant in the course of the cycle, such as the transition to Top Dead Center Admission or even at the bottom dead center Admission.
  • One of the important features of multipoint electronic injection is its intermittent operation, the injectors are in effect activated periodically: at least once per engine cycle, or again in the case of a four-stroke engine once for two turns crankshaft or 720 ° angle.
  • injection sequential is preferably phased so that that the opening of each injector ends before opening the intake valve of the corresponding cylinder, opening just starting before switching to Neutral Top Admission of corresponding cylinder.
  • the object of the present invention is to remedy the disadvantages of tracking systems known used to operate systems engine control electronics operating a phased sequential injection, by proposing a electronic system synchronization process simple and efficient control requires no specific position sensor in apart from the one used to locate the position angle of the crankshaft.
  • the system synchronization process combustion engine control electronics internal multi-cylinder consists to produce a synchronization signal, intended especially in the phasing of the injection, which allows the identification of a predetermined instant in the course of each person's operating cycle cylinders, such as shifting to Neutral High Admission (or even the transition to Neutral Low Admission, etc.).
  • This synchronization signal according to the invention is deduced from two distinct signals produced by suitable processing means using in particular the information provided by a angular position sensor cooperating with a ring gear carried by the crankshaft engine.
  • the first signal provides an estimate of the level of successive combustions occurring in the engine cylinders and the second signal follows the displacement of the pistons and in particular their passage in a predetermined position such as the Point Death High.
  • the method of developing a synchronization signal is based on the principle of action and reaction.
  • the action consists in operating adapted modifications to the parameters of engine control so as to generate opposite direction variations in the level of combustion in two cylinders whose cycles are offset by 360 ° crankshaft (or two-stroke engine).
  • step d) of the quantity representative of variations in levels of combustion for the affected cylinders is carried out taking into account a given number of cycles engine.
  • the distribution of the action over several motor cycles limit accordingly the amplitude of the variations in the combustion level and therefore to make the process of driver undetectable synchronization (lack of jerk in the operation of the engine).
  • This number of cycles which can be constant or even depend on the operating point engine, is determined so as to limit the variations in combustion levels while allowing rapid implementation of the process.
  • the predetermined conditions required in step b) to modify the parameters of combustion include stability conditions of all or part of the parameters acting on the engine combustion level, such as rpm engine rotation, or ignition advance, or the inlet pressure, or even the stable state auxiliary members driven by the engine.
  • changes to control parameters provided for in step c) consist of changes in the amount of fuel injected in the affected cylinders.
  • Changes in the quantities of fuel injected into the cylinders can be performed by application in the formulas of calculation of the injection times of a coefficient multiplicative corrector mapping according to engine operating conditions, said coefficient preferably between 0.7 and 0.99 for a cylinder and between 1.01 and 1.3 for the other.
  • changes in fuel quantities injected into the affected cylinders are adapted to engine operating conditions and in particular the pressure of the intake air, so as to produce a variation in the level of combustion in the cylinders which is substantially identical regardless of the operating point of the motor.
  • the first signal to monitor the level combustions in each cylinder operates a quantity representative of the gas torque generated by each of the engine combustions.
  • the calculation provided for in step d) consists of counting the combustion levels after a period of adapted timing according to the modifications of the control parameters operated in step c).
  • changes to the control parameters of the engine provided in step c) are suitable for generate at least one cyclic variation of the levels combustion in each of the affected cylinders, each cycle consisting of a first period during which the combustion level is improved for one cylinder and degraded for the other, and a second period of the same duration as the first period and during which we reverse these variations keeping essentially the same amplitudes.
  • changes to control parameters provided for in step c) are operated so similar on several groups of two cylinders (n ° 1, n ° 4; n ° 2, n ° 3) shifted by two engine times.
  • FIG. 1 we see, presented in a simplified way, the configuration an electronic engine control system with internal combustion using the process of synchronization object of the present invention. Only the constituent parts necessary for the understanding of the invention have been detailed.
  • the internal combustion engine which is marked 1 is more particularly intended for equip a motor or road vehicle.
  • This four-cylinder in-line engine and four time is equipped with a device for injecting the multi-point fuel with control electronics through which each cylinder is supplied with fuel from an electro-injector 5 specific.
  • each electro-injector 5 is controlled by the electronic system of command 7 also called the injection computer.
  • the injection computer 7 determines the quantity of fuel injected and the instant of injection into the cycle according to the operating conditions of the engine from known adapted strategies otherwise like for example the enslavement of the richness of the fuel air-fuel mixture admitted into cylinders at a set value predetermined.
  • the injection computer 7 comprises conventionally a microprocessor (CPU), random access memories (RAM), read only memories (ROM), as well as analog-to-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-to-digital converters
  • the microprocessor integrates circuits electronics and software suitable for process signals from sensors adapted, determine the engine conditions and put implement predefined operations in order to generate control signals at destination including injectors (and ignition coils in the case of a positive-ignition engine) according to the adapted strategies selected.
  • the injection computer 7 is more particularly suitable for operating an injection indirect sequential phased fuel which is to trigger each injector 5 so that the fuel injection be completed before the opening of the corresponding intake valves.
  • crankshaft sensor 22 is fixedly mounted on the engine mount to be positioned in front of a measuring crown 12 secured to the flywheel attached to one end of the crankshaft.
  • This crown 12 is provided at its periphery with a succession of identical teeth and hollows except for one tooth that has been removed in order to define a absolute benchmark allowing to deduce the instant from shift to Top dead center of a cylinder piston reference data, in this case the cylinder No. 1.
  • the sensor 22 therefore delivers a signal Dn corresponding to the scrolling of the teeth of the crown 12.
  • This signal Dn allows, after processing by suitable calculation means, to generate a TDC signal identifying each crankshaft U-turn simultaneous passages at Top Dead Center pistons of cylinders n ° 1 and n ° 4 then alternately the simultaneous passages at the Point Dead Top of pistons of cylinders n ° 2 and n ° 3 (The cylinder n ° 1 being for example the most close to the crown 12 and so on).
  • the processing of the signal Dn emitted by the sensor 22 also allows speed measurement scrolling teeth of the crown 12, and so to obtain the instantaneous rotation speed of the engine.
  • This signal Dn is further processed by calculation methods described below to produce a signal Cg for measuring the gas torque generated by each of the combustions.
  • the first step of the process object of the invention consists in creating a signal NOCYL synchronization.
  • This NOCYL signal is more particularly suitable for spotting an instant predetermined in the course of the engine cycle used for the phasing of the injection of each of the cylinders, which in the example illustrated is the transition to Neutral High Admission but which could be the transition to bottom dead center Admission, or any other time that can be used for injection phasing.
  • This NOCYL synchronization signal is phased with the TDC signal and it is arbitrarily initialized to 1 (or 0), at the first detection of the change to Top dead center of a cylinder reference, such as cylinder # 1, which is therefore arbitrarily considered a Top Dead Center Admission, then it is incremented (modulo four) at each shift to Top Dead Center of a cylinder in the order of succession of combustions in cylinders.
  • the modification made which consists of enrich certain cylinders and impoverish others is suitable for causing variations in level opposite direction torque between cylinders shifted in the cycle, by two engine times. he just assign the torque values to matching cylinders using the signal NOCYL predefined and summing it for deduce from the sign the value thus obtained if the NOCYL signal is well phased or not.
  • the required operating conditions to operate the wealth modifications as well as the amplitudes of these modifications are chosen so as to limit the impact of the implementation of the engine operation procedure and avoid any jolting phenomenon of the vehicle that may be felt by the driver, while allowing a safe and indisputable identification by analyzing torque values provided by signal Cg.
  • the second step of the process therefore consists to determine if the operating conditions of the engine allow wealth changes necessary for the implementation of the invention.
  • the required operating conditions to limit the impact on the functioning of the driving wealth variations concern more particularly the transmission ratio, which should preferably be above a predetermined value, as well as the parameters of engine operation including pressure and the regime which must be within ranges of predetermined values.
  • the required operating conditions must also allow safe location and undeniable torque alterations resulting wealth changes made. It suits therefore that the alterations detected by through the gas torque signal Cg result many wealth changes generated according to the process which is the subject of the present invention and no noise affecting the measurement signal of the gas torque Cg.
  • the stability criterion retained can be defined by maintaining parameter values selected within a range of values for a given time.
  • the forks values can then be fixed or even given by function tables of the values taken by these parameters.
  • the magnitude of wealth changes operated on the different cylinders is also adjusted according to the operating conditions of the engine to limit the impact of these modifications on engine operation and avoid all vehicle jerk phenomenon which can be felt by the driver, while allowing a safe and indisputable identification through analysis of the signal Cg of the resulting torque changes.
  • the correction coefficient PARTINJ is chosen so that the alteration of the corresponding gas torque is between predetermined threshold values Smin and Smax, Smin corresponding to the minimum value below which the decrease in torque is not discernible from the noise affecting the signal Cg, this threshold Smin therefore has a predetermined function value the noise level observed and an adjustable margin, and Smax corresponding to the maximum value above which the decrease in torque causes a jerk.
  • the values of correction factor are chosen to produce a comparable effect over the entire pressure range, which is obtained by choosing values of the PARTINJ coefficient according to a function of inlet pressure.
  • N is predetermined. Her value results from a compromise between the speed of implementation of the synchronization process and the amplitude of the torque variations (i.e. again the amplitude of the PARTINJ coefficient).
  • the process object of the invention operates in a fourth step summations of the gas torque measurements provided by the signal Cg corresponding to each of cylinders. Assigning torque values supplied by signal Cg to cylinders is operated by exploiting the signal NOCYL predefined.
  • S1 be the sum for the first gas couple period corresponding to different cylinders.
  • the sum S1 is operated in positively accounting for torque values corresponding to the rich cylinders and negatively the corresponding torque values to poor cylinders.
  • This second summation begins with the same delay of n-1 cycles (at least one cycle) so that on the one hand the torque measurements recorded effectively take into account the new wealth changes and secondly so that the sums S1 and S2 have the same number (N-n) of terms.
  • the sum S is independent of the average torque values of different cylinders. It only depends on torque alteration resulting from the coefficient corrector applied 1 +/- PARTINJ and the number of engine cycles taken into account. The dispersions of torque between cylinders is therefore not involved in the implementation of the method according to the invention.
  • This method has many benefits.
  • the calculation of the sum S being calculated with a large number of torque values, The influence of noise on the measurement of torque decreases, the errors compensating each other. Furthermore, the calculation based on a large number of torque values it is possible to operate with a small torque deviation ⁇ Cg and in particular lower than the noise affecting the signal Cg, which further limits the impact of the strategy on the behavior of the engine.
  • the strategy implemented frees itself from the error made on the calculation of the gas couple Cgj, i. Indeed, the rich-poor permutation partially compensates for the error made on estimating the torque, we add the error when the cylinder is rich, we subtract the error when the cylinder is poor.
  • This strategy frees itself from instabilities on the torque which can to exist. The impact of poor combustion is diluted by the large number of torque values taken into account.
  • This second variant is therefore based on the similarity of the torque values medium between the cylinders. More dispersions are large between the mean torque values of cylinders and less such a strategy is performance. If on the other hand the dispersions are weak, this strategy is effective and quick to enforce.
  • the invention includes all technical equivalents applied to a internal combustion whatever its type injection, the fuel used diesel or petrol or the number of its cylinders.
