Abstract
The present invention relates in order to optimize for multiple cylinders（64）Internal combustion engine operation fuel distribution, wherein, in order to fuel distribute, be provided with directly injection and intake manifold injection, the present invention propose, during internal combustion engine operation, at least one cylinder（64）Individually determine by directly the distributed fuel meat of injection and the fuel meat distributed by intake manifold injection and according to the injection strategy so known（61）Distribution fuel.
Description
Technical field
The present invention relates to a kind of corresponding for running the fuel dispensing methods and one kind of the internal combustion engine with multiple cylinders
Fuel dispensing system.
Background technology
The operation of the internal combustion engine directly sprayed with intake manifold injection and gasoline makes using two spray regimes for optimal
Mixed Daqu and the attendant advantages of resulting burning be possibly realized, realize that fuel expends in this way in addition
Reduction.Specifically, in the case of full load and when increasing in the dynamic of internal combustion engine, the direct spraying system of gasoline is more
Advantageous, because the tendency in this pinking is smaller.Conversely, intake manifold injection is advantageously in the case of fractional load
, because in the quantity of this particle, especially soot particulates, and the quantity of the hydrocarbon produced in burning is less.
People being interpreted as injection strategy for optimal mixed Daqu and the used spray regime of burning, the injection side
Formula can be directly injection（DI）, intake manifold injection（PFI）Or combination thus（DI-PFI- splits operation）.According to current
Prior art in injection strategy with most critical in other words for the corresponding operating point most critical of internal combustion engine（kritischsten）'s
According to cylinder.This means injection strategy provides the space for optimizing.
The content of the invention
Task of the invention is internal combustion engine of the optimization with DI- systems and PFI- systems in terms of consuming and waste gas discharge
Operation.
The task is so to be solved by way of introductory song is mentioned, during the operation of internal combustion engine, at least one
For cylinder, individually（individuell）It is determined that by being directly injected into the capable fuel meat for distributing and being sprayed by air inlet pipe
Penetrate the fuel meat that is allocated and distribute fuel corresponding to the injection strategy so known.Preferably for each cylinder
For individually determine injection strategy.
According to the present invention, thus no longer for whole motor but cylinder individually determines injection strategy.This means spy
It is other to be, no longer determine that DI-PFI- splits operation in the universal mode of cylinder for whole motor, but individually for each gas
Cylinder knows a fractionation coefficient.Furthermore, it is possible to realize that other cylinder is in DI- patterns and other cylinders are in PFI- patterns
In operation.
The present invention especially has the advantages that the range of operation for extending intake manifold injection, and the range of operation is partially by list
The pinking of individual cylinder easily generation property or combustion stability is restricted, and this can make motor in terms of consuming and waste gas discharge
Further optimization is possibly realized.
According to a possible implementation method of the invention, the optimized operation for each cylinder injection path is stored corresponding
Characteristic Field in, individually know injection strategy by this feature cylinder.This preferably relatively enters with the operational factor of motor
OK, for example, motor rotary speed, motor load, intake air temperature, motor temperature, the method for operation（Continuous operation, in shifts operation, middle fortune
OK）, AGR- rates, the Valve controlling time, Valve controlling curve, fuel type（Such as octane number and/or alcohol content）.According to
Workability, the difference for striving the accuracy and expected consuming for reaching, for knowing for the individual injection strategy of cylinder, can be with
Consider the different combination of above-mentioned operational factor.
By the method according to the invention or equipment of the invention, asked in terms of motor heat in the outer region
The cylinder that can be overheated in the case of topic is to the direct switching sprayed or can improve DI- parts, the heat side
Face problem is for example different caused by infield or intake air temperature.In this way due to the fuel for evaporating
The discharge of heat, directly produces stronger cylinder interior to cool down in the cylinder so that pinking tendency is fatefully sprayed by DI-
The raising of the amount of penetrating part and reduce.
Pinking, the delayed adjustment at current execution point fire angle are prevented during in order to be adjusted in pinking（Spä
tverstellung）.The angle of ignition adjusts more remote towards delayed direction, and burning position of centre of gravity is more rearward and pinking is inclined to just
It is smaller.
Modification of the invention, the direction passage that cylinder is individually matched and directly sprayed towards gasoline splits system
Number, to reduce pinking tendency in this way.In this way at least for for single cylinder cause the angle of ignition
Deposit（Zündwinkelreserve）Return（Zurücknahme）, the both angle of ignition that selects and optimal igniting for cylinder
The spacing at angle is possible, is burnt at limit of detonability in the optimal angle of ignition.One can be realized in this way
Individual other consuming advantages.Carried out on both paths according to a possible implementation method pinking regulation：Adjusted by the angle of ignition
Whole quick interference and the part return by splitting coefficient and the angle of ignition（Rückführen）The relatively slow curing of change relate to.
According to a particularly advantageous implementation method, study pinking interference and the change of resulting fractionation coefficient and
It is adapted to for each motor sample（adaptieren）Optimal injection strategy.The basic application of motor is therefore, it is possible to by so-called
Optimal-case support and range of operation need not be limited to the so-called worst-case of single cylinder-OK again for PFI
For.
One possible implementation of the adaptation can by one targetedly adaptation pattern be used as it is special run into
OK.Here, for example all of cylinder runs under pure DI- patterns, critical on pinking（kritischen）Operating point at.
Alternative targetedly adjustment for being to carry out the angle of ignition, is used to realize the critical operation on pinking herein
Point.In a subsequent step for the cylinder for selecting split coefficient towards intake manifold injection（PFI）The change in direction, directly
To the burning that can determine pinking.Then, the fractionation coefficient is preserved for the cylinder.Preferably, the preservation and operating point
Relatively carry out.Afterwards, the method is performed for other cylinders.Therefore, pinking can individually be optimized for each cylinder
Regulation.
It is alternative to be, can specify to start adaptation pattern in pure PFI- runs herein.In critical operating point
So adjust the angle of ignition for cylinder so that pinking occurs just.Next DI- parts are improved, until no longer there is pinking
Burning.Here, be favourable to the angle of ignition and the interference for splitting coefficient, because the angle of ignition towards " in advance " side should alternately be made
To and split coefficient towards " DI " direction adjust, be used to know optimal parameter.
Additionally, the determination of the injection strategy individual for cylinder is advantageously, comprising following parameter, correlation and/
Or it is one or more in characteristic：
- for calculating and/or correcting wall film flow（Wandfilmflusses）Wall membrane modle, not only for air inlet pipe also pin
To combustion chamber；
The injection of calculating with the selection of the-cylinder individuality lighted a fire, i.e., for example current correlation for splitting coefficient；
- heat engine operational factors（Warmlauffaktor）；
- for correcting the moment model of torque dissimilarity, the torque dissimilarity interfered by the angle of ignition and/or cylinder individuality valve
