Description
Technical field
The present invention relates to a kind of method for operation of combustion engine and a kind of for implementing the computing unit of the method.
Background technique
Air/fuel than regulating as follows by a lambda controlling device for so-called homogeneous operation in petrol engine, and the mean value that makes the lambda value of all cylinders is λ=1.0.Can realize thus the low waste gas operation with common ternary catalyzing unit, described ternary catalyzing unit is known in the situation that of stoichiometric(al) combustion has its maximum effect.
Because other air/fillings of dosage tolerance and cylinder is poor, for example, due to system tolerance, although identical manipulation, also difference mutually of the lambda value in the single cylinder of an internal-combustion engine.Also be known as the lambda value that the value by the each single cylinder total actual value of lambda, that measure combines below and therefore can there is rating value 1.0 in waste gas, although the single actual value of described lambda is around this mean value fluctuation.
For example there is the single actual value λ of lambda for the cylinder Zyl.1 of four cylinder motors to cylinder Zyl.4
zyl.1=1.1, λ
zyl.2=0.9, λ
zyl.3=1.2 and λ
zyl.4=0.8, draw the total actual value λ of a lambda
zyl.1 ... 4=1.0.The corresponding deviation of single cylinder and mean value (about single cylinder, a kind of cut down (Vertrimmung)) is known as cylinder disequilibrium in the application's framework.
Cylinder disequilibrium has a series of shortcomings.The reduction of cylinder other lambda value first directly causes the raising of fuel consumption.If described reduction has exceeded a definite threshold value, also worsen in some cases discharge.In the case, for example, load the one-tenth tuft of caused so-called waste gas due to different cylinders, i.e. the formation of the fluid line in exhaust mass stream also plays a role.Be worth that expect and sometimes desired by legislator, the waste gas that can identify this type of worsens and/or proofreaies and correct (ausregeln) by suitable regulation strategy.
From known in the state of the art different from identifying or proofread and correct the method for the operating cylinder disequilibrium of homogeneous.
The signal that can analyze on the one hand lambda sensor, wherein, becomes described signal decomposition single, relevant to cylinder value and evaluates.This for example describes in WO 96/35048 A1.But the usability of the method depends on consumingly the geometrical construction of waste gas circuit and motors designs and waste gas line design have been proposed to high requirement, these requirements usually cannot meet.
Method based on rotating speed specifies the identification of the amount mistake (Mengenfehlern) of described motor in lean-burn operation (λ > 1) on the other hand.In the case, all cylinders are transferred to simultaneously to lean-burn in service and evaluate about the cylinder of galloping other feature.Different from homogeneous operation, in service at lean-burn, motor torque is associated with emitted dose linearly.In order to ensure the operation of a waste gas neutrality and obtain total lambda lambda=1.0, break hereinto one follow-up, for invalid the spraying into again of moment.Therefore the method is not suitable for suction tude motor.To this corresponding method and for example open in DE 195 27 218 A1, DE 43 19 677 A1, DE 10 2,004 010 412 A1, DE 197 33 958 A1, EP 0 929 794 B1 and DE 10 2,006 026 390 A1 and the elaboration of other viewpoint.
All aforesaid methods all need a kind of so-called full motor operation, and wherein, all cylinders are all lighted a fire.But modern motor solu-tions regulation, for the conservation of fuel in low partial load scope, cuts off single cylinder completely, thereby no longer burns in these cylinders.This operation is also known as half motor operation part motor operation in other words.
Therefore, be also desirably in described half motor operation in other words the best lambda in part motor operation regulate.
Summary of the invention
Under this background, the present invention suggestion has a kind of method for operation of combustion engine of feature of independent claims and a kind of for implementing the computing unit of the method.Favourable design proposal is the theme of each dependent claims and specification below.
Be used in one for moving the framework of method of the internal-combustion engine with at least two cylinders according to measure as suggested in the present invention, described internal-combustion engine moves at least two running statees.At this, in the first running state, all cylinders of described internal-combustion engine are lighted a fire in order to produce a corresponding motor torque, for example, at common motor operation, a four-stroke in service, utilize a fuel/air mixture to load and be activated and light or stand one from ignition method.At at least one in other running state, only the part in described cylinder, only a unique cylinder is lighted a fire in some cases.
In all running statees, be fitted to by fuel quantity and/or air quantity that the cylinder to each igniting (altogether) is carried the total actual value of a lambda that adjusts described internal-combustion engine on the total rating value of a lambda by means of a lambda regulator.This is known as overall lambda adjusting and fully open in the prior art.As partly set forth before, described lambda actual value has illustrated the stoichiometric proportion existing respectively in described internal-combustion engine.Raising by the fuel quantity carried respectively about existing air, can make a corresponding fuel/air mixture " thicken ", it is the value that described lambda value moves to <1, and make a fuel/air mixture " thinning " by reducing the fuel quantity of carrying conversely, described lambda value correspondingly moves in the scope of >1.
Now, if realize part motor operation, i.e. other a method of operation, wherein, only the part in described cylinder is lighted a fire, can be in the change that occurs the total actual value of described lambda in the situation that described the first running state is switched to described the second running state by cancelling single cylinder.As described above, the single actual value of each lambda need not be corresponding with the total actual value of described lambda, for example, in the time existing other air/filling of dosage tolerance and/or cylinder poor.Therefore, the single actual value of described lambda can have deviation with the total actual value of described lambda, and wherein, the single actual value of described lambda generally forms the total actual value of described lambda.Therefore, if now do not take extra measure, immediately after described switching, may there is the mixture of an excessively rare overrich in other words, i.e. too high too low total lambda actual value in other words.This lambda mistake has been damaged the discharge behavior of described internal-combustion engine and must be corrected.
Therefore the regulation according to the present invention, in the case of being switched to from described the first running state (described full motor operation) other a running state (described part motor operation), described lambda regulator (its conditioner outlet end in other words) loads with a pre-control value, and this pre-control value resists the movement of the total actual value of described lambda and preferably as wide as possible by its compensation.If improved the total actual value of described lambda by a part of cutting off in described cylinder, a lambda regulator (its conditioner outlet end in other words) can load with a pre-control value, this pre-control value improves the fuel quantity that flows to generally described motor (and/or reducing described air quantity) in the corresponding way, thereby again obtains the total rating value of desirable lambda (being for example 1).Conversely, when be switched to described other running state from described the first running state, can cause reducing of described lambda value, described lambda regulator (its conditioner outlet end in other words) can be loaded with a pre-control value, this pre-control value has reduced described fuel quantity (and/or having improved described air quantity).
Therefore the present invention has realized the favourable pre-control that holistic lambda regulates, and utilizes this pre-control can resist the movement of the total actual value of described lambda.A kind of suitable pre-control value can be for example determined by the change of lambda conditioner outlet end described in observing in the time switching.This change is stored as suitable pre-control value.
Be according to the special advantage of the one of measure of the present invention, by the extra intervention of the described output terminal for described lambda regulator, make described adjustable parameter (being the total actual value of described lambda) approximate constant.It is unhelpful that a kind of lambda correction is in operation, because the mistake input that the adjustable parameter of described lambda regulator is usually monitored by automotive system and disadvantageous adaptation value meeting (vacation is here (falschpositiven) pro) leads to errors in storage.
In the particularly preferred mode of execution of one, except the lambda of described entirety regulates, a kind of cylinder other lambda is also set and regulates.In the situation that described cylinder other lambda regulates; determine that for each cylinder of being lighted a fire one for revising to the fuel quantity of each cylinder conveying and/or the correction factor of air quantity; so that on the single rating value of lambda that also single the lambda of each cylinder actual value is adjusted to an expectation, λ=1 substantially conventionally.In this design, the present invention can bring into play special advantage.In the situation that other lambda of some cylinders regulates, described correction factor is so definite, they average 100% draw (correction of the whole system that therefore produced by described cylinder other adaptation value come lambda neutral carry out; Just do not wish the movement of the total actual value of described lambda).Therefore, conventionally occur, in the time of described switching, the correction factor of remaining cylinder is not 100% to draw and correspondingly will follow the tracks of.But this tracking has changed the total actual value of described lambda and has caused the intervention of described lambda regulator, and this should be avoided.
When the total actual value of described lambda is adjusted to while carrying respectively equal fuel quantity on the total rating value of described lambda and to described cylinder by the lambda regulator of described internal-combustion engine, advantageously carry out described cylinder other lambda and regulate.In this framework, described cylinder other deviation is preferably confirmable.At this, described fuel capacity rating need not be corresponding with carried fuel actual amount, for example, in the time existing deviation, valve needle occupied etc. in the injection behavior at described injection valve.At this, one rating value-actual value difference may be a cause of cylinder other lambda deviation, but needn't show as a unique cause.In described the first running state, that is to say, in the time that all cylinders are all lighted a fire, adaptation value that the fuel quantity that flows to each cylinder of being lighted a fire regulates by means of stack described (entirety) lambda based on each definite characteristic parameter (local, that is to say that cylinder other lambda regulates) is adaptive as follows, makes the single actual value of each lambda corresponding with the total actual value of described lambda at least largely.At this, if as previously mentioned, other cylinder has the lambda value of >1, correspondingly improves corresponding fuel quantity (and/or reducing described air quantity) by described adaptation value.Conversely, in the time of individual other lambda value <1 of described cylinder, reduce described fuel quantity (and/or improving described air quantity).In other words, carry out cylinder other adaptation of the single actual value of described lambda and the total actual value of described lambda.
Required correction, that is to say that the corresponding pre-control value for described lambda regulator that uses can for example be determined in the following way in the time of described switching, described internal-combustion engine (for example, in the framework of a test/trial running mode) is converted into described other running state and determines the movement of the total actual value of a consequent described lambda from described the first running state.After the movement of the total actual value of determined described lambda, extended meeting is directly taken in the corresponding pre-control in the framework of an adjusting operation.
Can be also advantageously, determine in the following way described pre-control value, the correction factor of the cylinder based on each igniting (adaptation value) be known the movement of the total actual value of desired described lambda.Can for example use a characteristic curve, in this characteristic curve, the corresponding deviation of described total adaptation value is converted into lambda correction value for this reason.Alternatively or additionally, can from described lambda regulator (first uncorrected) be switched to the reaction of described part motor operation after in other words half motor operation in other words adjustable parameter in changing, determine a correction.
According to computing unit of the present invention, the controller of for example Motor Vehicle or internal-combustion engine, especially program technic Shangdi is provided for implementing the method according to this invention.
Described method is also favourable with the execution of the form of software, because it has caused especially little expense, in any case particularly when the controller of implementing is also for other task and while therefore all existing.For particularly floppy disk, hard disk, flash memory, EEPROM, CD-ROM, the DVD etc. of suitable data medium of computer program are provided.It is also feasible downloading via computer network (internet, in-house network).
Other advantage of the present invention and design proposal provide from specification and accompanying drawing.
It being understood that above-mentioned and also feature to be explained below not only can be in the combination of correspondence explanation, and can be in the situation that not leaving framework of the present invention in other combination or with independent form application.

In Fig. 1, schematically there is shown an of Motor Vehicle and block overlooking, this Motor Vehicle has an internal-combustion engine 10, this internal-combustion engine has fuel system 20, supply air system 30 and waste gas system 40 and a computing unit 50, and this computing unit is as the controller for manipulating described Motor Vehicle.Described internal-combustion engine 10 is preferably configured as the petrol engine with direct injection.Described internal-combustion engine 10 comprises four cylinders 11,12,13,14 in an illustrated embodiment, but can be also the cylinder of any other quantity.Fuel is provided and is ejected into respectively in described cylinder 11,12,13,14 via corresponding injection valve 21 by described fuel system 20.
Carry air via described supply air system 30 to described cylinder 11,12,13,14, wherein, for each in described cylinder 11,12,13,14, an intake valve 31 is set.Gas of combustion is discharged from described cylinder 11,12,13,14 via exhaust valve 41 and is exported via described waste gas system 40.One catalyst converter 42 is set in described waste gas system 40, and it mainly transforms carbon monoxide and nitrogen oxide and is advantageously configured to ternary catalyzing unit.
The actuator of described controller 50 and described internal-combustion engine 10, described fuel system 20, described supply air system 30 and/or described waste gas system 40 is in effect is connected, in order to manipulate in suitable mode.Specifically, described controller 50 for example manipulates described injection valve 21, described intake valve 31, described exhaust valve 41 and other actuator.Especially described controller 50 is configured to preset by means of described injection valve 21 fuel quantity of a definition.Described controller 50 can have a lambda regulator 52 that is configured to the parts of described controller 50.Be provided for implementing to described controller 50 program technics the method according to this invention.
In addition, suitable sensor is set, as lambda sensor 51 especially, it is arranged in the upstream of described catalyst converter 42 in described waste gas system 40; And unshowned temperature transducer and/or pressure transducer are set, in order to detect corresponding motor state, thereby can realize according to these sensors the operation of described internal-combustion engine 10 by means of described controller 50.Described lambda sensor 51 is provided for detecting the oxygen content in described waste gas system 40 and itself or a corresponding value deriving thus is for example delivered on a lambda regulator 52 of implementing in described controller 50.
Described controller 50 is by means of manipulation order O or manipulate described internal-combustion engine by the transmission of corresponding parameter, in order to a driving moment to be provided.For this reason, described controller 50 obtains input value I, and it for example comprises outside requirement, for example driver's demand moment, and the pedal position etc. that travels, utilizes them can preset from outside a driving moment demand.In addition, described controller 50 obtains the corresponding information about motor state as input value I from described sensor, for example, pressure and temperature in rotating speed, supply air system 20 and/or waste gas system 40.
In full motor operation, all cylinders 11,12,13,14 of described internal-combustion engine 10 are all activated and for example four-stroke operation fully disclosed according to one and that do not elaborate is here lighted a fire with a default order.
According to the difference of desirable running state, the difference of the running state of for example predefined value of driver's demand moment or described internal-combustion engine 10, a for example free-runing operation, described controller 50 can determine, described driving moment should be respectively by described cylinder 11,12,13,14 only one or only a part provide.In this case, cutting off cylinder 11,12,13,14 or the one group of cylinder of being lighted a fire accordingly 11,12,13,14 that at least one and total driving moment in described cylinder 11,12,13,14 only also lighted a fire by a quilt provides.Corresponding part is cut off and is known as part motor operation.At this, if cut off the half in described cylinder 11,12,13,14, be called half motor operation.Described half motor operation has represented the standard of described part motor operation, because the mechanical structure of described internal-combustion engine 10 is by minimally load.In the case, also can specify, be switched to another group cylinder 11,12,13,14 from one group of cylinder 11,12,13,14, thereby for example described cylinder 11 and 13 be lighted a fire in the first running state, and lighted a fire at cylinder 12 and 14 described in the second running state.
Fig. 2 there is shown the interchangeable diagram of the one of blocking of Fig. 1 in side-looking, wherein, again do not set forth for the purpose of general view with the corresponding element of Fig. 1.At this, a series of parts in this diagram, are given up, the parts of especially described automotive system 20, described supply air system 30 and described waste gas system 40.
In described cylinder 11,12,13,14, arrange respectively piston 11', 12', 13', 14'.The gas force being applied on described piston 11', 12', 13', 14' the in the situation that of corresponding cylinder 11,12,13,14 igniting is delivered on a bent axle 15 in piston rod 11'', 12'', 13'', the 14'' of described piston via attaching troops to a unit.In the case of the cylinder disequilibrium of setting forth before, for example, the cylinder disequilibrium in the case of different fuel quantities, be applied to that gas force on described piston 11', 12', 13', 14' changes and the uniformity of the therefore rotational motion of described bent axle 15 also changes.One corresponding nonuniformity is also known as galloping.
In order to determine described galloping, a sensor wheel 16 connects with described bent axle 15 in anti-relative rotation.The rotational motion of described sensor wheel 16 for example reflects in the signal 53' of a rotation angle sensor 53.A described controller 50 in other words evaluation module 54 correspondingly arranging is evaluated described signal 53' and is therefrom determined cylinder other value.
In Fig. 2, in side view, visible described sensor wheel 16 has the mark 16' distributing on its circumference.These marks 16' can be for example ferromagnetic projection, and their edge produces the precipitous edge in described signal 53' when through an inductive pickup as speed probe 53.Described sensor wheel 16 can be divided into segmental arc.Each segmental arc can have the mark 16' of a predetermined quantity.By the counting to signal edge, described controller 50 is confirmed respectively beginning and the end of a corresponding segmental arc, and determines the following segmental arc time, at the described speed probe 53 of the process of segmental arc described in this segmental arc time.
In Fig. 3, schematically show according to a kind of method of particularly preferred mode of execution and represented with 100 generally.
In the first method step 1, the internal-combustion engine 10 of an internal-combustion engine, for example Fig. 1 and 2 turns round in a full motor operation.In the case, in order to realize a homogeneous operation, a lambda regulator is adjusted to the total actual value of a lambda of described internal-combustion engine 10 on the total rating value of a lambda continuously, for example, in the value of being adjusted to 1.0.By a suitable method, for example, by means of a galloping method, know cylinder other lambda deviation and respectively by regulating the adaptation value superposeing to compensate according to described lambda, that is to say and also single the lambda of single cylinder actual value is adjusted on the single rating value of a lambda, for example, in the value of being adjusted to 1.0.
In the second method step 2, obtain a corresponding manipulation signal 50' by the controller 50 of a control gear, for example Fig. 1 and 2, it requires part motor operation or half motor operation.If obtained corresponding signal 50', carry out the manipulation that utilizes a pre-control signal 52' of described lambda regulator 52, this pre-control signal resists the intervention of described lambda regulator 52.For this reason, especially the output signal of described lambda regulator is especially utilized multiplication to load with a pre-control value.This pre-control value can be kept in a corresponding control gear as previously mentioned.Described pre-control value can be known in the following way, for example after switching for the first time, detects the reaction of described lambda regulator and stores.Afterwards, in follow-up handoff procedure, seal on described lambda conditioner outlet end stored result as pre-control value, thereby described lambda regulator itself needn't be reacted again.
In third method step 3, described internal-combustion engine turns round in half motor operation, wherein, for the corresponding pre-control of described lambda controlling device 52 be activate and thus a total lambda is remained on to desirable rating value.Described method can cyclically be implemented, and as shown in arrow 110 by a dotted line, turns back to step 1, that is to say that described internal-combustion engine 10 can be transferred in a full motor operation again.
For example, can be the in the situation that of four cylinder motors in full motor operation for single cylinder Zyl_1 to Zyl_4, draw the following actual ejection amount (EM) in the case of 100% specified emitted dose: EM_Zyl_1=100%, EM_Zyl_2=100%, EM_Zyl_3=100%, EM_Zyl_4=140%.
The single actual value of described lambda is directly proportional to described emitted dose indirectly with enough degree of accuracy, λ _ Zyl_1=1, and λ _ Zyl_2=1, λ _ Zyl_3=1, λ _ Zyl_4 ≈ 0.71, has drawn about 0.93 the total actual value of lambda thus.
The lambda of entirety regulates and the emitted dose on all cylinders can be reduced to: EM_Zyl_1 ≈ 93%, and EM_Zyl_2 ≈ 93%, EM_Zyl_3 ≈ 93%, EM_Zyl_4=130%, in order to realize the total actual value of lambda that equals 1.
Now, the single actual value of described lambda is taking enough degree of accuracy as about: λ _ Zyl_1 ≈ 1.08, λ _ Zyl_2 ≈ 1.08, λ _ Zyl_3 ≈ 1.08, λ _ Zyl_4 ≈ 0.77.
Other lambda controlling device of described cylinder can utilize mean value=1 to determine following correction factor (FAK): FAK_Zyl_1 ≈ 1.08, FAK_Zyl_2 ≈ 1.08, FAK_Zyl_3 ≈ 1.08, FAK_Zyl_4 ≈ 0.77.
In full motor operation, draw thus: EM_Zyl_1=100%, EM_Zyl_2=100%, EM_Zyl_3=100%, EM_Zyl_4=100%.
The for example cut-out of cylinder 3 and 4 can cause the change of described correction factor, in order to obtain described mean value=1:FAK_Zyl_1=1, and FAK_Zyl_2=1, and correspondingly cause holistic thinning: EM_Zyl_1 ≈ 93%, EM_Zyl_2 ≈ 93%.
Lambda regulator described here can take-off and described mixture thicken, in this example with coefficient 1.08.This should thereby be avoided for set forth above former.In addition,, thickening must be returning in connecing and is again adjusted in described full motor operation after a while.Two kinds of interventions of described lambda regulator are in fact all unnecessary.
In conversion of the present invention, be parallel to the switching in described half motor operation, take the pre-control in the lambda of described entirety regulates.By this intervention, equal the thickening of the thinning time by the lambda regulator through pre-control (the lambda conditioner outlet end in entirety described in above-mentioned example for example carries out pre-control with a coefficient 1.08) causing due to the adjustment of described update the system compensates.The pre-control of described lambda regulator can be for example determined by should be used for before.In the case, as previously mentioned, for the each dense movement there will be by described adaptation value in the situation that being switched to half motor operation rare movement in other words, preserve one of described lambda regulator and revise accordingly.Alternatively, also can consider, after being switched in described half motor operation, measure described lambda vary, and the correction of the described lambda regulator causing is thus carried out to adaptation for a pre-control enduringly.
A special advantage of the method for advising is that " defective sight " (systematic error) existing in some cases at lambda sensor described in described half motor operation is taken into account in described pre-control together.Thus after the adaptation in the situation that being switched to for the first time in a part of motor operation, acquire a value accordingly, thereby in switching in the future, no longer need the reaction again of described lambda regulator.
