Press can also be provided with recycle valve, and it is arranged in the bypass line between the input of the compressor of supercharging device and output end
It is interior.The recycle valve is used for reducing or avoids compressor to occur compressor surge completely, and described compressor surge may
It is being to occur in the case that operation in boost range is quickly changed to underload from high load capacity.
The content of the invention
According to the present invention it is proposed that a kind of method and a kind of control unit, engine for being used to run supercharged engine
System, computer program product.
The invention further relates to other preferred configurations.
The method for running internal combustion engine is proposed according to the first angle.The internal combustion engine is configured in air
Worked under guiding operational mode and fuel guiding operational mode, particularly thin operational mode or layering operational mode, and
And including the supercharging device with the compressor for being used to provide fresh air under boost pressure.Methods described includes following step
Suddenly：
- checked in the operational mode that air is guided, if it is required that changing the driving moment needed, this change can be led
The range of operation for causing compressor unstable；
- if it is determined that require to change driving moment, and this change can cause the unstable range of operation of compressor, then
Internal combustion engine is run with the operational mode that fuel is guided.
If occurring the compressor surge of compressor, the unstable range of operation of compressor is just at least had.If in supercharging
Occur pressure difference between input and output end in the compressor of device, but require nothing more than or delivered minimum air mass flow
Volume flow in other words is measured, will occur compressor surge.In this case, this may occur disconnected on compressor blade
Stream, this typically results in the operation noise of interference and may damage the compressor blade and/or axle and/or axle of turbocharger
Hold.
Using thrust scavenging air valve to avoid this running status for compressor surge occur of compressor from meaning that additionally
Input and especially mean extra cost, reduce the reliability of whole system because thrust scavenging air valve be and therefore
Hinder another component of probability correlation.In optional engine system, thrust scavenging air valve is also partly abandoned, wherein, increase
The compressor of pressure device must be designed to firm and durable, particularly the axle and bearing this respect between compressor and turbine.
Noise generation appeared in it must be inhibited as desired by extra acoustic engineering measure.
One kind of the above method it is contemplated that, with thin operation mould under the running status for being likely to occur compressor surge
Formula and thus fuel guide ground to run internal combustion engine.
In internal combustion engine, compressor surge can especially occur under a kind of running situation：Wherein from based on high drive square
Low driving force square should quickly be provided by setting out.In this case, the air throttle that generally close immediately in gas handling system, so that
MAF declines rapidly, and pressure difference is then still had between the input of compressor and output end.Although air quality
The slow decline of flow is conducive to avoiding compressor surge in this case, but can not realize, because passing through other method
The reduction of torque is only limitedly used for reducing driving moment for example obtained from angle of ignition intervention.
Because compressor surge especially can and simultaneously compressor low in the MAF or volume flow conveyed
Input and output end between pressure difference it is high in the case of occur, the above method can cause, due to being changed into fuel guiding

Amount）It is reliable temporarily to interrupt, it the substitute is, aeration quantity namely the MAF into cylinder be able to can excluded reliably
Kept when showing the irregular operation of compressor, being particularly the minimum value of compressor surge.
Therefore any too high fuel quantity would not be sprayed to the combustion chamber of cylinder, in the operational mode that fuel is guided in
Disconnected λ regulations, the λ regulations can spray the fuel quantity with the aeration quantity equivalent in cylinder and then instead spray now less
Fuel quantity, the fuel quantity correspond to provided driving moment.One thrust ventilation need not can be set in this way
Valve or similar other structures measure, only avoid compressor surge by changing the operational mode of internal combustion engine.
In addition, it is desired also to check whether that requirement changes by such mode in the operational mode that air is guided
Driving moment, the driving moment causes the unstable range of operation of compressor：Driven by checking for for desired
The requirement of kinetic moment, this requirement causes the MAF of the fresh air in cylinder of internal-combustion engine to change, and thus exists
Compressor is set to be run in unstable range of operation on compressor during existing pressure difference.
The explanation of driving moment that especially can be desirably or according to for provide need driving moment needed for air
The explanation of mass flow implements the inspection for whether requiring to change desired driving moment.
According to a kind of embodiment, can postpone or suppress in the operational mode that fuel is guided MAF to
It is used for providing the suitable MAF of MAF of desired driving moment in air guides operational mode
Direction changes, so as to avoid the shakiness that pressure difference of the compressor on by compressor and the MAF on compressor are determined
Range of operation in fixed range of operation.
If desired driving moment is provided in the operational mode that air is guided brings such MAF, its
It will not make it that compressor is run in unstable range of operation in terms of pressure difference on compressor, then internal combustion engine can exist again
Run in the operational mode of air guiding.
In addition, unstable range of operation can be represented by an engine combined characteristic or a function,
Which define the pressure difference in unstable range of operation and compressor and the pass between the MAF on compressor
System.

Brief description of the drawings
Below the preferred embodiments of the invention are further illustrated by accompanying drawing.Wherein：
Wherein：
Fig. 1 is the diagram of the engine system with an internal combustion engine and a supercharging device；
Fig. 2 is the figure of the range of operation of the compressor surge for illustrating wherein to be likely to occur compressor；And
Fig. 3 is for the method figure for the operation method for illustrating the internal combustion engine such as Fig. 1.
Embodiment
Fig. 1 shows that includes an engine system 1 for internal combustion engine 2, and it has three cylinders 3 in present case.It is interior
Combustion engine 2 corresponds essentially to Otto engine, and it can work in four strokes.Air is led by inlet casing 3 by gas handling system 4
In, section 5 is exported by waste gas and discharges from cylinder 3 burning waste gas.
One supercharging device 6 is set, and it can be constructed in the form of exhaust gas turbocharger.Supercharging device 6, which has, to be arranged in
Turbine 61 in waste gas export section 5.The turbine and the compressor 62 that is arranged in gas handling system 4 are for example by one
Axle is coupled.Compressor 62 is from around drawing fresh air and being compressed, to provide the fresh air under charge-air pressure.
Supercharging device 6 is exported from waste gas to be obtained energy by turbine 61 in the exhaust enthalpy in section 5 and uses this energy to drive
Dynamic compressor 62.
Compressor 62 has compressor wheel blade, and it causes surge effect or compression by rotation, so as to will be fresh
Air is transported to the output end of compressor from the input of compressor, so as to provide new under higher charge-air pressure with this
Fresh air.
Gas handling system 4 additionally has air throttle 7, and it is arranged in before the upstream of supercharging device 6 and cylinder 3.Section
Air valve 7 is used for adjusting the air capacity into internal combustion engine 2, and the driving moment provided by internal combustion engine 2 is dependent on the air capacity.It is logical
It is often the given position to adjust air throttle 7 of driving moment as needed, to preset filling in the cylinder 3 of internal combustion engine 2
Tolerance.In λ=1 there is also such range of operation, air is adjusted by supercharging device 6 when air throttle 7 is opened wherein
Quality.
In addition, setting a lambda seeker 8 in the waste gas export section 5 in the downstream of turbine 61 of supercharging device 6, it is used
To examine the oxygen content of waste gas and provide an input parameter for so-called λ regulations.λ regulations ensure that in internal combustion engine 2
The air/fuel mixture of after-flame lies substantially in stoichiometric balance state in cylinder 3.
Internal combustion engine 2 is run by control unit 10.Described control unit 10 is calculated by sensor or model and obtained
Information in terms of system mode.For example bulk information can be such as led into the information in terms of the MAF in internal combustion engine 2 and carried
Control unit 10 is supplied, wherein, such as by hot-film air sensor by the supercharging pressure being instantaneously present in air inlet section 4
Power, the λ value instantaneously drawn by lambda seeker 8 is for example supplied to control unit by boost-pressure sensor.
In addition, control unit 10 is also comprising parameter preset, it for example represent needed for, internal combustion engine 2 should provide
The explanation of driving moment size.The intervention of control unit 10 is essentially by regulation air throttle 7, by spraying the combustion in inlet casing 3
The given of doses and the ignition time point that passes through the igniter in cylinder 3 is carried out.Control unit 10 can carry out λ regulations,
It can carry out metering fuel amount according to the air capacity in cylinder 3, so that burning is carried out when λ value is about 1 substantially herein.
If the parameter preset that control unit 10 is provided shows to be rapidly low driving force by high drive torque conversion
Square, then will have higher pressure difference between the input and output end of compressor 62 first.In addition, passing through compressor 62
The MAF of conveying is also higher, because the requirement of high drive square has high aeration quantity in cylinder 3.If parameter preset table
It is bright to need only provide for minimum driving moment now, then because internal combustion engine 2 is air guiding, usual air throttle 7 is just immediately
Completely or almost entirely close, so that the air mass flow for entering cylinder 3 by compressor 62 is almost interrupted.Thus exist
Unstable running status is formed in compressor 62, it can cause cutout or backflow on compressor wheel blade, and may cause
The generation of the high load capacity and noise of compressor 62.
Figure 2 illustrates for illustrate wherein occur compressor surge range of operation（Dash area）Line chart.Can
To find out, High Pressure Difference Δ p and low MAF that can be on compressor 62Under conditions of occur compressor surge.Especially
It is for each MAFFor there is the boundary value of pressure differential deltap p on compressor 62, the pressure difference is said
Understand in compressor 62 from stable state to unstable state（Compressor surge）Transformation.Compression can be also used in these figures
Pressure ratio on machine replaces the pressure difference.In addition, these figures generally also include mass flow, the volume of temperature and pressure correction
The volume flow of flow or temperature adjustmemt.
In order to avoid being wherein likely to occur the running status of compressor surge, a kind of method is now set, can by Fig. 3 side
Method figure further illustrates this method.
In step sl, air quality to be regulated is drawn by parameter preset and system mode in the control unit 10
Flow value.If detecting MAF in step S2 inquiryChange（Option：It is）, i.e., step S3's
By function such as Fig. 2 provided in a look-up table or mathematic(al) representation from memory or suitable function in inquiry
Ground draws the maximum of corresponding, reliable pressure differential deltap p on compressor 62 as pressure difference boundary value.Also can using input with it is defeated
Go out the substitution of the pressure ratio between end pressure differential deltap p and be used as reference variable.
It can be drawn in step s 4 by measurement or model instantaneous between the input and output end of compressor 62
Pressure difference pressure ratio instantaneous in other words is used as instantaneous differential pressure value.
If the risk that there is forcing press surge is determined by the contrast between pressure difference boundary value and instantaneous differential pressure value（Also
It is to say, occurs in that（Shown in dash area）Operating point in the range of irregular operation）, that is, the regulation of air throttle 7 is intervened, then
Air throttle is not that to continue to close and maintain instantaneous position be exactly to be opened further in addition, to make bigger air
Quality stream enters in cylinder 3.This, which is ultimately resulted in, will limit regulation variable gradient of the air throttle 7 to the direction of air throttle 7 of closing, because
Can constantly it decline when MAF reduces for the pressure difference on compressor 62.The above-mentioned pass for limiting air throttle 7 can be passed through
Close motion to ensure, the operating point of internal combustion engine 2 can be moved along Fig. 2 margin line, until pressure difference is small to no longer there is compressor
The degree of the risk of surge.
Nevertheless, in order to ensure the quick reduction of driving moment, regulation stops λ tune in step s 4 in this case
Save and allow thin operation layering operation in other words.If the burning in the cylinder of internal combustion engine is to be more than 1 with oxygen excess i.e. λ value
Carry out, the thin operation of internal combustion engine will be formed.In layering operation, it can be generated in the subregion of the combustion chamber of cylinder
The flammable air/fuel mixture of stoichiometric balance.This is can in structure based on the internal combustion engine for methods described
Implement thin operation or layering operation.Then, control unit 10 can draw fuel quantity to be sprayed, to allow internal combustion engine 2
To provide driving moment to be supplied（According to parameter preset V）.As a result, the fuel quantity sprayed is less than fuel to be reached and sky
Fuel quantity needed for stoichiometric balance between gas.
So, instantaneous differential pressure value has just been drawn again in step s 5 now.If by inquiring that step S6 is determined, instantaneous pressure
The reduction for the boost pressure that difference is provided by compressor 62 and decline, until in the absence of the journey of any compressor surge risk
Degree（Option：It is）, then just can again it be changed into from instantaneous thin operational mode in the step s 7 according to a kind of embodiment
Normal operation mode is the operational mode of air guiding：Mode is to reduce air quality by being further turned off air throttle 7 now
Flow, is used for the air quality for providing desired driving moment until the MAF corresponds in normal operation mode
Flow.Otherwise（Option：It is no）With regard to rebound step S3.
Method and step S1 and S7 are preferably circulating repetition, with the operation for the compressor 62 for ensuring to monitor supercharging device 6 always
State.
In another embodiment, it can also be decided whether that normal operation mould can be performed according to the change of parameter preset
Formula.The change of parameter preset is characterized to be turned from the high drive square asked to the quick time for the low driving force square asked
Become, this can be by terms of the time change of parameter preset（The parameter preset of each unit interval is poor, the parameter preset time is terraced
The change of degree etc.）Suitable threshold comparison be achieved, thus can be according to a constant gradient or according to by presetting
The graded that the change of parameter is determined postpones or completely inhibited the closing immediately and instead immediately of air throttle 7
Be converted to the thin method of operation or layering operation.So, during the process of thin operational mode, so that it may in view of compression
The surge boundary of machine 62, i.e. be no more than surge boundary of the compressor 62 on the direction of irregular operation scope under conditions of, lead to
The MAF that the corresponding staged or continous way of air throttle 7 close to be lowered into cylinder 3 is crossed, until being led
The MAF entered corresponds to the MAF that desired driving moment is provided in normal operating condition.
