Description

Method and apparatus for recognizing the incandescent ignition in petrol engine
Technical field
The present invention relates to a kind of method for recognizing incandescent ignition in petrol engine, the incandescent ignition is with passing through spark The igniting of plug is independently appeared in gasoline engine combustion chamber, and a kind of apparatus for carrying out the method.
Background technology
In petrol engine, the burning of the Air-fuel mixing thing of supply causes vehicle to put into running operation or keep row Sail operation.In the development of modern gasoline engine, show that the petrol engine miniaturization combined with direct-injection and supercharging becomes Gesture.Here, miniaturization means that the technical size, such as weight or stroke space of petrol engine diminish, however still So reach and power same or similar in larger petrol engine.This can be realized, because supercharging can reduce gasoline The stroke space of engine is without reducing power level.Thus, petrol engine can be negative in part in the case of higher load Run in load with higher part load efficiency and fuel consumption can be reduced.However, improving supercharging in order to improve efficiency Pressure causes the very high heat load of gasoline engine combustion chamber.This causes incandescent ignition, and the incandescent ignition is in gasoline engine Part in machine combustion chamber reaches too high temperature and when thus mixture lighted uncontrolledly.It is this undesirable vehement Thermal ignition occurs after the ignition time point triggered by spark plug and forms an additional flamjne front first, and the flamjne front causes Air-fuel mixing thing quickly after-flame.Thus, the temperature in combustion chamber is further raised, so that this undesirable self-ignition is with vehement Before the mode of thermal ignition always starts and appears in ignition time point at some earlier.If not interrupting this mistake Journey, this incandescent ignition formation already results in so high pressure and temperature after the burning of relatively small number so that gasoline Engine direct receives damage.
This incandescent ignition can not with it is other in gasoline engine combustion chamber, or the early fire that occurs (Vorentflammung) differentiate.These Wall Vibrations for causing gauge combustion chamber are detected by means of structure-borne sound sensor Early fire and incandescent ignition.In addition, can also recognize incandescent ignition and early fire by means of analyzing the revolution of crank axle.
The content of the invention
Thus, task of the invention is, proposes a kind of method, by this method can Direct Recognition incandescent ignition, and Recognize early in the cylinder with the process for the incandescent ignition for further burning and continually strengthening every time.
Thus the task is solved according to the present invention, i.e. analysis occurs before or after the ignition time point of spark plug Chamber pressure, for determining incandescent ignition, wherein, multiple mistakes are also observed in addition to the chamber pressure of a current combustion The chamber pressure for the burning gone.This is had the advantage that, i.e. the pressure is directly inerrably provided from gasoline engine combustion chamber Information, incandescent ignition can be reliably recognized by means of the pressure.Here, can save on solid sound or revolution information Indirect analysis.The identification of incandescent ignition can by this way with or the identification of early fire separate.The individual of incandescent ignition Situation show with or early fire as.If observing repeated combustion, it is possible to distinguish.Between or occur early fire be The individual instances not associated especially with the early fire occurred before.This morning fiery no omen and can be on position and intensity Change.On the contrary, incandescent ignition shows completely specified behavior pattern.Incandescent ignition is at first in the pilot spark by spark plug And the burning started starts during carrying out lately.By the burning of this acceleration, the temperature in combustion chamber is further up, and it is tied Fruit is that the incandescent ignition occurred in burning next time has begun to earlier.This behavior is repeated until incandescent ignition ratio Burn and occur earlier as caused by the pilot spark of spark plug.Lighted from this time, further burning is completely out of control Carry out, and further elapsed in the case of without counter-measure to early.Incandescent ignition occurs more early, petrol engine Pressure load and temperature load it is higher.Thus, incandescent ignition show it is obvious from reinforcing effect, this by incandescent ignition and Or the early fire occurred is clearly distinguished out.
Advantageous by chamber pressure, preferably petrol engine observed cylinder chamber pressure, according to Crank angle draws burning position.Thus, it is possible to reliably determine, the burning detected is actually early fire or incandescent ignition. Recognize that occurred incandescent ignition makes it possible to take corresponding counter-measure in advance, thus, it is possible to avoid stronger incandescent spot Fire.
In a kind of configuration, burning position is determined in n continuous burning successively of cylinder, wherein, if first The burning position determined during secondary burning is relative to the burning position determined during n-th is burnt continuously towards combustion earlier The direction movement of position is burnt, then draws the conclusion of incandescent ignition.By continuously to the smaller ignition time point of crank angle Direction movement burning, incandescent ignition can significantly with or early flame range separate, the early fire can also be in petrol engine Occur in combustion chamber.Counter-measure can be introduced by the time identification of incandescent ignition, petrol engine is thus protected from infringement. This way enables in particular to use when developing the petrol engine with higher degree of miniaturization for more preferable efficiency.
Advantageously, burning position is corrected according to operating point (load, revolution, ignition time point) respectively.
In a kind of modification, continuously the quantity n of burning successively is at least 2.Because the burning of incandescent ignition continuously to It is preceding to be moved from a Daqu Shaft angle to the direction of an ignition time point compared with Chinese yeast Shaft angle, only burn several times and be just enough to determine this The trend of kind and the conclusion for thus reliably drawing incandescent ignition early.
In order to directly determine incandescent ignition by chamber pressure, the burning position drawn by chamber pressure is by burning chamber pressure Power it is surge pressure, determine especially with respect to the position of crank angle.Here, the position of the surge pressure corresponds to accordingly Crank angle, wherein, preferably it is determined that deducting compression share before burning position from chamber pressure.However, it is possible to consider Temporal correspondence.Thus, it can be completed for analyzing the simple application of chamber pressure in engine control system.It is preferred that also Can be it is determined that before the surge pressure of chamber pressure, also being deducted from chamber pressure change curve due to filling and compressing And the part produced by expansion (is used as the portion produced in the inertia running (Schubverlauf) in petrol engine Point), only to observe burning.
In one embodiment, the thermal change curve and/or integration on crank angle are derived by chamber pressure Thermal change curve, determines that one is used for measuring for burning position by the thermal change curve and/or integral heat change curve.Here, saying It is bright to discharge the thermal change curve of heat in each crank angle degrees during burning and determine during burning in this time mistake There is provided on pressure such as burning combustion chamber condition and formed herein for the integral heat change curve of the energy generally discharged in journey The just the same reliable information of chamber pressure itself.
Advantageously, a fitting a straight line is completed based on the burning position determined in the n burnings asked (Ausgleichsgerade) knot of incandescent ignition, and by the absolute value of the slope of the fitting a straight line and/or the slope is drawn By.By a fitting a straight line, can particularly simple determine the trend, i.e. the burning whether on the direction of ignition time point to Preceding movement and whether be herein incandescent ignition.In the case of identification incandescent ignition early, corresponding counter-measure can be introduced, and And reduction incandescent ignition is for the effect of petrol engine.
In a kind of configuration, if the absolute value of the slope of the fitting a straight line and/or the slope is more than each previously given Threshold value, then recognize an incandescent ignition.This threshold value compares a kind of simple analysis of displaying and in the application can be particularly advantageously Processing.Thus reduction application expends.
In a kind of flexible program, in order to recognize incandescent ignition, the intercept of the fitting a straight line is analyzed, especially when the intercept phase During Ying Yuyi burning positions late for given operating point.The analysis of this intercept is especially can not by fitting a straight line It is enough clearly to determine during the trend it is favourable.If the intercept corresponding to one relative to ignition time point crank angle and The big crank angle of speech, then it is assumed that form an incandescent ignition.
In a kind of configuration, one for the crank angle of ignition time point big, burning position crank angle Identified, its mode is compared the burning position with the average value of the burning position of the subnormal burnings of m or with one in the vapour Reference value determined by one operating point of oil turbine compares.Compare measure further simplified engine control dress by this Application in putting.
A modification of the present invention scheme is related to a kind of device for being used to recognize the incandescent ignition in petrol engine, and this is vehement Thermal ignition by the igniting of spark plug with independently being appeared in the combustion chamber of petrol engine.In order to well will be red-hot Light a fire with or early flame range separate, there are some devices, the device is from each one cylinder chamber for detecting petrol engine The pressure sensor of middle pressure receives signal, and analyzes before or after the ignition time point of spark plug from the pressure The chamber pressure occurred in sensor, for confirming incandescent ignition, wherein, in addition to the chamber pressure of current combustion also Observe the chamber pressure of multiple past burnings.This has the advantage that, i.e. higher being realized for the more preferable efficiency of petrol engine Degree of miniaturization when, protect gasoline engine generator from due to caused by incandescent ignition damage.Furthermore it is possible to reliably will be red-hot Igniting with the middle of gasoline engine combustion chamber or appearance early flame range separate.
Advantageously, the device includes a signal sensing unit and a signal analysis device, wherein, signal analysis dress Put the counter-measure introduced for recognized incandescent ignition.When recognizing incandescent ignition ferment, strong, pass through reply Measure reduces the power of petrol engine, so as to the temperature produced by thus reducing in petrol engine.These counter-measures example If being to reduce filling, enrichment or enleanment (abmagern) Air-fuel mixing thing, regulation camshaft or close to spray.
For diagnostic purpose, the incandescent ignition recognized is stored in a fault memorizer and can tested by workshop Personnel transfer.
Brief description of the drawings
The present invention allows a large amount of embodiments.One of them will be elaborated by means of the figure being shown in the drawings.
Accompanying drawing is shown:
Fig. 1 is used for the device for determining the incandescent ignition in petrol engine,
The diagram of the development of Fig. 2 incandescent ignitions.
Embodiment
Fig. 1 shows the device for determining the incandescent ignition in petrol engine 1.This is configured to the vapour of self-priming engine Oil turbine 1 has four cylinders 2 in this embodiment, 3,4,5, these cylinders it is not shown further, in cylinder 2,3,4,5 The piston of motion is connected with bent axle 10 by a connecting rod 6,7,8,9 and driven based on the pressure change caused by burning respectively Move the bent axle.Cylinder 2,3,4,5 is connected with suction tube 11, and the suction tube is terminated by a choke block 12 relative to air intake duct 13. Nozzle 14 for spraying into fuel is reached in air intake duct 13, is consequently formed Air-fuel mixing thing.Alternatively, petrol engine 1, especially It is that put-put can be designed with directly spray device, fuel is individually injected to each vapour by the directly spray device by an injector In cylinder 2,3,4,5.In another flexible program, a spray comprising a directly spray device and a suction tube injection apparatus can also be constructed Penetrate system variation.In addition, an important feature is supercharging device, the supercharging device is generally by a whirlpool not shown further Booster composition is taken turns, but can also be two-stage type.
In the combustion chamber of petrol engine 1, i.e., in cylinder 2,3,4,5, a pressure sensor 15a is respectively disposed with, 15b, 15c, 15d.The pressure sensor 15a, 15b, 15c, 15d are connected with controller 16.Controller 16 is connected to throttling On plate 12 and fuel injection nozzle 14.
When choke block 12 is opened, Air-fuel mixing logistics is into suction tube 11 and thus flows in cylinder 2,3,4,5.It is logical The spark triggered by spark plug not shown further is crossed, normal combustion, the normal combustion is triggered in succession in cylinder 2,3,4,5 Pressure is caused to rise in cylinder 2,3,4,5, the pressure rises through piston and connecting rod 6,7,8,9 is delivered on bent axle, and Make Crankshaft motion.During burning, the pressure condition in combustion chamber changes.Except described, in check normal combustion with Outside, it there is also due to being burnt caused by incandescent ignition, the burning, which has, to be in after normal combustion and then at normal Burning position after the ignition time point of burning.
Figure 2 illustrates incandescent ignition, these incandescent ignitions are appeared in continuous combustion period successively, wherein, with Bar draws for the chamber pressure p of unit above the crank angle φ in units of ° KW.Incandescent ignition refers to not expecting Burning, the burning is triggered by the pilot spark of spark plug, but component (example exhaust valve, the spark plug for passing through overheat Electrode) or triggered by the combustion chamber wall surface of the overheat of petrol engine.But, in fuel combustion in a combustion chamber The carbon distribution of formation can also cause this incandescent ignition.Here, the temperature of this incandescent ignition is far above Air-fuel mixing thing itself Temperature when can light a fire.The burning that the continuous direction to Chinese yeast Shaft angle of incandescent ignition is moved is (such as the arrow F institutes in Fig. 2 Show) and its by repeated combustion the effect strengthened certainly, can make incandescent ignition and or the early fire that occurs differentiate.In gasoline Due to cyclic fluctuation in engine 1, the burning position of the burning triggered by spark plug is generally around average value fluctuation, tool Have for a constant operating point and small, the clearly trend in the case where igniting corner is constant.
Controller 16 is carried for each basis of cylinder 2,3,4,5 by combustion chamber pressure sensor 15a, 15b, 15c, 15d Chamber pressure situation signal supply, incandescent ignition burning calculates burning position.Here, the burning position is in each cylinder 2nd, it is observed in 3,4,5 last n burning.Herein advantageously, last n burning position is corrected according to the angle of ignition. Where it determines that these burning positions, its mode is, according to what is provided by combustion chamber pressure sensor 15a, 15b, 15c, 15d Signal determines the crank axle angle position corresponding to peak combustion chamber pressure.It can advantageously be detained in advance from chamber pressure Except compression share.
Alternatively, the burning position is according to by the thermal change from the chamber pressure p thermal change curves derived or integration Change curve to calculate.The determination of burning position is realized by known integral heat change curve from the prior art, for example, pass through The time point in the 50% of maximum integral heat change curve or angle position φ is calculated to realize.Alternatively, it can also take Other values, such as 10% or 90% are used for 50%.Amount for burning position can be calculated by thermal change curve Degree, its mode is, the region before or after the position using the maximum of thermal change curve or the position in maximum In, 50% position of maximum.Thus, the chamber pressure in cylinder 2,3,4,5 is analyzed respectively about burning position P, wherein, chamber pressure p is always fully analyzed in other words in the region that may potentially burn in high pressure phase It is middle fully to be analyzed.When the operating point of petrol engine 1 changes, because spark delay also changes, it should at least in load It is corrected with terms of revolution.
Studied according to the individual burning positions obtained by surge pressure, correction of n, if there is such trend, i.e. combustion Position is burnt to move to burning position earlier.Here, the burning quantity n that burning position analysis is carried out for it may be at two Between 20 burnings.The n value based on burning position, determines a fitting a straight line.The fitting a straight line can for example pass through Least squares estimation (Least-Squares-Schaetzung) is drawn.Here, the slope of the straight line is towards combustion earlier The trend for burning position is measured.For example it should be observed that:During n=1, crank angle φ of the burning with -35 ° of KW;During n=2, burning Crank angle φ with -27 ° of KW;During n=3, crank angle φ of the burning with -23 ° of KW.By these crank angles and thus The fitting a straight line of determination can draw a slope.The slope so drawn is compared with a reference value being stored in controller 16. If the slope exceedes reference value, draw in conclusion ferment, strong incandescent ignition and introduce counter-measure.But It is that in addition to the slope, the absolute value that can also analyze the absolute value of the slope and be also deposited with one in controller 16 is referred to Value compares.In this case, if the absolute value of slope exceedes absolute value threshold value, also draw fermenting, strong vehement The conclusion of thermal ignition.
Typically, the generation of strong incandescent ignition starts with very late burning, that is to say, that burning position has One big crank angle φ, the crank angle is at a distance after the ignition time point of normal combustion.In follow-up combustion period, The burning in the evening is then moved to smaller crank angle φ direction and leads to the strong incandescent ignition that should be avoided.From passing through The analysis of fitting a straight line is set out, and can also analyze the intercept of estimated fitting a straight line equation.The fitting a straight line equation is then:
Y=a × burning+b.
Corresponding to the burning position of the surge pressure in φ=- 35 ° KW in the example that intercept b is handled above.Because Intercept b supported corresponding to very late burning, then by intercept b in guess ferment, strong incandescent ignition and Strengthen.Here, evening burning position can by with the normal combustion as caused by spark plug it is last some burn average value Relatively or by from one be adapted in the controller and be stored in the controller, for different operating points Reference value is relatively obtained.
In order to perform the analysis, controller 16, as shown in Figure 1, with a signal sensing unit 17, The signal sensing unit receives pressure sensor 15a, 15b, 15c, 15d for being arranged on petrol engine 1 signal.These quilts The signal of reception continues to be transferred on the signal analysis device 18 of controller 16 from the signal sensing unit 17, the signal analysis Device realizes the above-mentioned realization side of the signal analysis in the way of the fitting a straight line equation for constituting fitting a straight line and being estimated Formula.Signal analysis device 18 is connected with an incandescent ignition recognition unit 19, the incandescent ignition recognition unit perform with reference value or Person says the comparison of threshold value and therefrom drawn on the inference in the incandescent ignition fermented.
If detected by incandescent ignition recognition unit 19 in the incandescent ignition fermented, generation reply in the module 20 Measure, its mode is, either controller 16 controls choke block 12, or control injection valve 14.Here, these counter-measures can be with To reduce filling, enrichment or enleanment Air-fuel mixing thing, regulation camshaft or closing injection.By all these measures come Thus the temperature reduced in the power of petrol engine 1, the combustion chamber of petrol engine 1 reduces, and this suppresses the formation of incandescent ignition.
The analysis for incandescent ignition always can in this case be activated advantageously in controller 16, i.e. In the presence of for incandescent ignition very critical condition, advantageous development goes out incandescent ignition under these conditions, such as with high As given by the operating point of engine loading and high engine temperature.In the analysis of methods described, for workshop For it is possible that specific input item in the fault memorizer for passing through controller 16 targetedly finds and eliminated combustion The reason for burning the focus in room.A kind of typical failure situation is that the ceramics of spark plug rupture, and then thus spark plug overheats simultaneously And cause incandescent ignition.
