In Fig. 4, overview, illustrates the poor side for calculating the fuel consumption in the first and second operational modes
Method step.First operational mode refers to such operational mode：Wherein, only fuel is added to the internal combustion engine according to Fig. 1 to 3
Combustion chamber 101 in.Second operational mode refers to such operational mode：Wherein, fuel and water are added to the internal combustion
In the combustion chamber 101 of machine.Pass through concept：Water sprays and water adds and illustrates identical content because water add generally by
The injection that is carried out by means of valve is carried out.By the way that water is added in combustion chamber together with fuel, realize in combustion chamber 101
The cooling of burning.On the one hand this cooling can be required for protection internal combustion engine from too high temperature（Thermally required
Cooling）, otherwise the improved efficiency for the combustion process being used in the combustion chamber.
The protection of internal combustion engine is necessary especially in the operation phase, for example longer oepration at full load that larger heat is loaded
's.Therefore, in traditional internal combustion engine, so-called enriching at full capacity is carried out, that is, the fuel-air ratio in the combustion chamber
Moved in traditional motor towards largely fuel excess, so as to actually can compared to added air is passed through
The fuel of burning, more fuel are located in the combustion chamber.This extra fuel facilitates the cooling of combustion chamber and therefore
It is the suitable measure for reducing the ignition temperature in the combustion chamber.If instead of the additional amount fuel and at this
Injection water in a little operation phase, then can reach identical cooling effect, so that, as in traditional motor, no longer
Need required enriching at full capacity.Thus, in the operation phase of these larger heat loadings, a part for fuel can be direct
It is replaced by water, and this point will not be associated with the power loss of internal combustion engine.Thus, this effect has directly obtained conservation of fuel,
Because replacing the fuel, add water in the combustion chamber.
In addition, adding water in the combustion chamber also in others in the operation thermally without so big heat loading
The raising for cooling down and facilitate the thermodynamic (al) efficiency with being attached thereto of burning is facilitated in stage.This effect is especially
Performance is that it is possible to preferably select the center of gravity of the burning, because especially moving border, the border generally have to by
The burning of pinking formula in the motor considers.By adding water in the combustion chamber 101, it can thus select to carry
The optimal angle of ignition of improved efficiency.Because so as to improve the efficiency of the internal combustion engine, then also achieving conservation of fuel,
Because realizing the identical power output of the internal combustion engine using less fuel quantity.
Now, the two effects are summarily illustrated in Fig. 4.In Figure 5, illustrate ask for it is described full negative based on replacing
The concrete condition of the consumption advantage of lotus enriching, and illustrate the efficiency sprayed and carried out by the water in figure 6 and change
Kind concrete condition.
The first operational mode and band in a combustion chamber asked in a combustion chamber only with fuel are schematically illustrated in Fig. 4
There is the difference of the fuel consumption between fuel and the second operational mode of water.In the first processing step 401, the fortune of internal combustion engine is asked for
Row parameter, such as load, rotating speed and fuel-air ratio is asked for if necessary（Lambda）.These operational factors pass through the internal combustion engine
The input of driver of real-time running status and vehicle obtain.So striked operational factor is shown as follow-up
The input value for asking for frame 402,403 and 405.In frame 402, in the running status of larger heat loading（Wherein, it is necessary to enter
Capable enriching at full capacity）Period, under the precondition in additionally adding water to the combustion chamber, calculate the fuel quantity.
In the processing step 403, during the running status（Wherein, it is necessary to carry out enriching at full capacity）, water is not being added
In the case of entering into the combustion chamber, fuel mass is asked for.Which running status is located exactly at according to the internal combustion engine respectively
In, then theoretic value is based only upon in the frame 402 and 403 to carry out one of described calculating, and other calculation blocks are extra
Ground can also be using the real-time measured value at the internal combustion engine as foundation.Value determined by so is then supplied to follow-up
Calculation block 404, the calculation block forms the difference of described two fuel quantities, wherein, this share return only guide to it is described at full capacity plus
Dense avoids.In addition, in the step 405 and subsequent step, it is poor that the improvement based on efficiency realizes calculating fuel.By
This, in step 405, is deduced the motor load of equivalence, namely by adding water in the combustion chamber or will not
Water is added to the change of the motor load carried out in the combustion chamber.Then, in step 406 followed by, form
Relative to the difference of real-time motor load, and in step 407, changing by this of motor load for the fuel quantity is asked for
Become realized difference.In follow-up step 408, the difference striked in step 404 and 407 of the fuel mass is cumulatively added
For the total poor of the fuel quantity.Step 409 follows the step 408, in the step 409, and the fuel quantity is by total
It is converted into the fuel quantity of unit interval.In step 410 followed by, from this fuel quantity of unit interval, Neng Goujie
Crossed section is closed to ask for the section of the fuel quantity or unit of fuel amount in unit section.Therefrom it is then able to follow-up
The conservation of fuel in percentage or in every 100km liters is asked in step 411, otherwise asks for effective row of the vehicle
The improvement of journey.Each in striked difference poor can be used control in the vehicle in the step 408 to 411
Process.
Also show the poor concrete condition that the fuel quantity based on required enriching at full capacity is asked for once in Figure 5,
Or the disappearance that the enriching at full capacity carried out is sprayed by water is shown just.In the first step 501, the fortune of internal combustion engine is recognized
Row point：Wherein, it is necessary to enriching at full capacity.In this regard, operating point is asked for, such as load, rotating speed, motor temperature, fuel quality, sky
Air tightness and other parameter, and so that it is determined that, the real-time operating point of the internal combustion engine requires extra cooling.Step
Rapid 504 and step 508 follow the step 501, in the step 504, ask for the fuel quantity when being added with water, and
In the step 508, ask for the fuel quantity or the fuel in the case of the combustion chamber 101 is not added water to and disappear
Consumption.Respectively according to whether water injection is feasible, then this asks for one of approach and carried out with pure can calculating, and others ask for approach energy
Enough measured values using real-time running status and the sensor of especially described internal combustion engine is foundations.In step 504, with water
Unit interval fuel quantity during injection is calculated from the operational factor of internal combustion engine, and is therefrom counted in step 505
Calculate the fuel quantity in unit section or the section of unit of fuel amount.In step 508, realize in the operation added without water
In the identical of unit interval fuel quantity calculate, and carry out the fuel quantity or list in unit of account section in step 509
The section of position fuel quantity.This value is generally greater than striked value in step 504 or 505.Step 504 and step 508 or
505 and 509 result in step 510 from drawing each other, and so as to ask for the combustion of the operation by being added with water
The difference or conservation of fuel of doses.Step 404 of the step 510 thus corresponding to Fig. 4.
The concrete condition of the calculating of the conservation of fuel based on the improved efficiency added by water is illustrated in figure 6.In step
In rapid 601, in this regard, recognizing the operating point of the internal combustion engine, in the operating point, improved efficiency can be carried out by water injection.
For example, in free-runing operation, inefficent improvement can be carried out by water injection, because, it is necessary to fuel in this operation
Specific minimum, burns to be maintained and does not therefore expect to be injected into line efficiency improvement by water.When such operation
Point（Wherein, improved efficiency is resulted in by means of adding water in the combustion chamber 101）When, in the step 601
It followed by following steps：In step 602 to 604, realize with water spray it is operating ask for, and in step
Asking in the case of being added without water is realized in 605 to 607.In step 602, when asking for such light a fire first
Carve：At the time of ignition, start burning by the pilot spark at spark plug.Then, the time of ignition this
Plant to ask for followed by and ask for angle of ignition efficiency in step 603, then therefrom added in step 604 for this with water
Operation calculate modeled motor torque.The meter of the time of ignition when being added without water is realized in step 605
Calculate, realize in step 606 calculating therefrom obtained angle of ignition efficiency, and therefrom calculate in step 607 for without
There is the modeled motor torque of the operation of water addition.Or these calculation procedures 602 to 604 or 605 to 607 are referred to completely
Or model calculate but consider for these calculating internal combustion engines sensor actual measured value.
If it is considered that the measured sensor values of internal combustion engine, then this asks for being referred to as " measurement " asking for, and
If the calculating is based only upon modeling, this calculates referred to as " theoretic " and asked for.Carried or not according to whether realizing respectively
With water add operation, then just measurement ground ask for or pure theory model these calculate one or another branch.
The result asked for described in step 602 to 607 is normally used as the other input asked for for the calculation block 611
Value.Here, using different input parameters for calculation block 611 according to running status respectively.Illustrate in figure 6 such
State：At this moment the operation sprayed with water is feasible.In this case, the modeled motor torque when being added with water
It is used as the input value for frame 611 with the angle of ignition efficiency when being sprayed without water, the motor torque is by step
Asked in 604, the angle of ignition efficiency is asked in step 606.If should for the operation sprayed without water
Realize that identical is calculated, then the input parameter for frame 611 can be from the modeled when being added without water of frame 607
Motor torque and the angle of ignition efficiency when being sprayed with water from frame 603.In example shown in figure 6, in frame 611
In, by the comparison of the modeled motor torque when being added with water and the angle of ignition efficiency when being added without water,
Operating point of equal value is calculated, the torque of equivalence is reached using the operating point of equal value.This motor torque of equal value is then in frame
It is scaled the motor load of equivalence in 612, the motor load and then is asked in step 613 to when being added with water
In the difference of motor load and motor load of equal value striked in step 612.Then, the motor load it is this difference with
With the difference that the fuel mass is scaled in step 614 thereafter.Then, correspondingly, by the fuel matter in step 615
The differential conversion of amount is conservation of fuel, or is scaled the consumption advantage of unit interval or percentile consumption in step 616
Advantage or the consumption advantage in every 100km liters.Frame of this value asked in block 616 thus corresponding to Fig. 4
407.Thus, asked for by this calculating, being obtained due to the improved efficiency that water injection is carried out based on internal combustion engine
How many conservation of fuel.
In figure 6, also the power reforming of internal combustion engine is calculated as other calculating.In this regard, when being added with water
Motor torque（Step 604）With the motor torque when being added without water（Step 607）It is compared to each other in step 608.
In step 609 by this differential conversion of the motor torque be corresponding difference power, then this make in follow-up step 610
Be scaled kilowatt for difference power or realtime power percentage.Thus, for the value for the power reforming that progress is sprayed by water
Or the value that the power for being carried out based on the water injection lacked is deteriorated is available.The vehicle with corresponding internal combustion engine can be given
Driver so show：The filling in for rule of the water storage tank sprayed for water has obtained how many conservation of fuel or how much power
Improve, or due to the how much raisings filled in without realizing fuel consumption or the how much power of the water storage tank that the water sprays delayed
Loss.Can so as to improve with band be possible to water injection internal combustion engine vehicle driver for regularly filling in the water
The enthusiasm of storage tank.
Now, illustrating in the figure 7 is used for the fuel difference calculated to control the internal combustion engine.In first step 701,
Realize that the poor reading of fuel quantity or the poor reading of fuel consumption or the fuel amounted on the specific period are poor first
Or the poor reading of the fuel consumption.Step 702 is followed by the step 701, in the step 702, asks for being used for
The storage tank liquid level of the storage tank for water ejected water in combustion chamber 101 and extraly ask in the vehicle if necessary
The liquid level of fuel tank.Followed by step 703 in the step 702, in the step 703, so striked value quilt
For controlling vehicle, particularly for triggering the process in vehicle.
In the step 703, especially obtained clout in the storage tank for water sprayed for water it is smaller when pair
In the advantage of the control of vehicle.If be filled up completely with for the storage tank that water sprays,（Whenever the operation sprayed with water it is feasible and
When meaningful）Also this water injection is realized.If the storage tank is empty for water injection, it can not realize that water sprays,
And therefore only realize the operation sprayed without water.In the two situations, calculate the difference and be merely and inform and drive
The person of sailing, especially to the driver show：The availability or unavailability sprayed by water（It is full based on the storage tank for water
Or empty）How many savings or how much more consumption obtained.
Especially when the clout in the storage tank for water be probably not enough to before the filling in of water next time it is continuously real
When now carrying the operation that water sprays, optimized.In order to foretell：Whether the no longer company of being enough of the water in the storage tank for water
The operation sprayed with water is realized continuously, especially considers the filling extent of the fuel tank.Generally it is expected that vehicle
Driver implements filling in for the fuel tank and water storage tank simultaneously, especially when the too small liquid level in fuel tank forces him to mend
When filling charging.Because while the operation of the motor vehicle in the case of being sprayed without water is possible, but not without combustion
Material, it is believed that, when the supplement filling of fuel tank is also necessary, just carry out the supplement filling of the storage tank for water.If
Filling extent based on the fuel tank is without expecting that the occupied state of the water storage tank is enough to realize with the continuous of water injection
Operation, then the safeguard measure that should reach is, optimizes water consumption.In this regard, can for example be provided that, water injection just only also exists
Realized in such running status：Wherein, it is especially big by the realized conservation of fuel of water injection.In this regard, depending on
The surplus of water in the storage tank for water, define for fuel difference threshold value, just realized in the threshold value from without
The operational mode for having water to spray is switched in the operational mode sprayed with water.Thereby, it is possible to realize such a operation：Its
The consumption as small as possible of fuel is still also achieved in the case of the surplus of water is less.
Optionally, such a operation can also be realized：It causes especially clean waste gas.As for
As Fig. 5 is implemented, enriching requirement is by extra fuel injection into combustion chamber at full capacity, and then the fuel do not fired completely
Export to surrounding enviroment with burning.Therefore, this waste gas is considered as particularly detrimental, is at least more harmful to than such waste gas：It is logical
It is still produced in the case of the complete burning of fuel to cross the consumption through raising.Therefore, in the water storage tank for injection
Residual liquid level it is smaller when, can be provided that, this injection is just only also used in such running status：Wherein, it is necessary to
Carry out enriching at full capacity.Can be so as to improving the quality of waste gas.
