Rapid S1~S10 is the part related to circulation stream formation control.As above summary description, circulation stream formation control is to close
The control that extraction valve 52 forms the circulation stream by the gas of power turbine 30 with this is opened during make and break valve closing 51.
First, control device 60 obtains various information（Step S1）.Specifically, control device 60 is based on coming from each equipment
Input signal obtain the direction of rotation of engine main body, engine speed, fuel input amount, scavenging pressure.
Then, control device 60 judges whether engine main body 10 is rotated forward（Step S2）.Engine main body 10 is rotated forward
When（"Yes" in step S2）, step S3 is carried out, when engine main body 10 is reversed（"No" in step S2）, carry out step S4.Its
In, in step s 4, extraction valve 52 is opened while open and close valve 51 are closed, step S1 is back to afterwards.Like this, starting
It is in order to avoid power is cancelled out each other between power turbine 30 and bent axle 11 that open and close valve 51 is closed when owner's body 10 is inverted.Also,
It is as described above to be formed by following that the gas of power turbine 30 is circulated that extraction valve 52 is opened when closing open and close valve 51
Circulation road is to mitigate engine load.
In step s3, judge currently whether to close as open and close valve 51 and extraction valve 52 is opened.I.e., in step s3, sentence
It is fixed（Confirm）How the opening and closing of open and close valve 51 and extraction valve 52 is determined in previous circulation.In addition, at least in step S3
During middle judgement, open and close valve 51 is opened, and extraction valve 52 must be closed, and open and close valve 51 is closed, and extraction valve 52 must be opened.Sentencing
Be set to open and close valve 51 close and extraction valve 52 opening in the case of（"Yes" in step S3）, the progress step of control device 60 S5.Also,
In the case where being determined as that open and close valve 51 is opened and extraction valve 52 is closed（"No" in step S3）, carry out step S6.
In step s 5, rotating speed and fuel input amount based on engine main body 10 calculate engine load, and judge
Whether the engine load is to rise more than switchable load.It is determined as that the result that open and close valve 51 is closed is to be walked in step s3
Rapid S5, it can be considered that performing the control for the make and break valve closing 51 that reaches a standard at least in previous circulation.Close open and close valve 51 be because
It is small for engine load, it is impossible to by exhaust supply to power turbine 30.Therefore, in step s 5, whether engine load is judged
In less state so that whether rising to and will can be vented without the supply of normal direction power turbine 30 exhaust or engine load
Supply to the degree of power turbine 30.That is, " rising switchable load " in step S5 refers to that engine load rises and can be by
Exhaust supply is for example set as 50% load to engine load during power turbine 30 in this embodiment（By engine
The peak load of main body 10 is set to 50% load when 100%）.
In step s 5, when engine load is rises more than switchable load（"Yes" in step S5）It will can exactly be vented
When supply is to power turbine 30, therefore open and close valve 51 is opened, close extraction valve 52（Step S7）.However, in this implementation shape
It is not that will close open and close valve 51 and open extraction valve 52 to carry out simultaneously in state, but across certain after extraction valve 52 is closed
Open and close valve 51 is opened after time.Assuming that closing extraction valve 52, then 52 liang of open and close valve 51 and extraction valve while opening open and close valve 51
The state that person opens temporarily occurs, so that the gas formed in power turbine entrance pipe arrangement 42 leads to not via power turbine 30
Cross the bypass flow path that pumping pipe arrangement 44 is discharged to power turbine exit pipe arrangement 43.The flow path resistance is smaller, therefore more exhaust
The stream is flowed into, the result is that being reduced by the capacity of turbocharger inlet pipe arrangement 41.By means of this, supplied by booster 20
The pressure of air changes, and there is the worry that engine main body 10 becomes unstable.In contrast, in this embodiment,
Open and close valve 51 is opened after extraction valve 52 is closed, is reduced quickly with the capacity that this suppresses to flow into booster 20.By step
Step S11 is carried out after rapid S7.
In step s 5, when engine load is less than and rises switchable load（"No" in step S5）, in can not continue
State of the supply to power turbine 30 will be vented, therefore maintains the state that open and close valve 51 is closed and extraction valve 52 is opened（Step
S8）.Step S1 is back to after step S8.
In step s 6, engine load is calculated based on the engine speed and fuel input amount obtained in step S1, and
And more than judging the engine load whether as decline switchable load.It is judged as the result that open and close valve 51 is opened in step s3
It is to carry out step S6, it can be considered that at least performing the control for opening open and close valve 51 in previous circulation.Open opening and closing
Valve 51 is, because engine load is larger, can to supply exhaust to power turbine 30.Based on this, in step s 6, hair is judged
The state whether engine load remains larger is supplied to whether power turbine 30 or engine load drop so that will can be vented
It can not will as little as be vented degree of the supply to power turbine 30.That is, " decline switchable load " in step S6 refers to that engine is born
Lotus declines and can not for example be set as 45% in this embodiment by exhaust supply to engine load during power turbine 30
Load（The peak load of engine main body is set to 45% load when 100%）.In addition, it is negative with rising switching to decline switchable load
The value of lotus is not both as caused by so-called hysteresis.
In step s 6, when engine load is declines more than switchable load（"Yes" in step S6）, continue to energy
It is enough to be vented state of the supply to engine main body 10, therefore maintain the state that open and close valve 51 is opened and extraction valve 52 is closed（Step
Rapid S9）.Step S11 is carried out after by step S9.
In step s 6, when engine load is less than decline switchable load（"Yes" in step S6）Exhaust can not exactly be supplied
When to power turbine 30, therefore open and close valve 51 is closed, open extraction valve 52（Step S10）.However, in this embodiment
In, the closing of open and close valve 51 is carried out when different with the opening of extraction valve 52, but across certain time after open and close valve 51 is closed
Extraction valve 52 is opened afterwards.Like this, the reasons why the reasons why extraction valve 52 are opened after closing open and close valve 51 with illustrating in step S7
Identical, the amount for being provided to suppress to flow into the exhaust of booster 20 is reduced quickly.Step S1 is back to after step S10.
＜ extraction flows control ＞
Then, illustrate that extraction flow is controlled.Fig. 3 step S11~S16 is the part related to extraction flow control.Row
Throughput adjusts control：Regulation is arranged at the aperture of the variable-nozzle 32 of power turbine 30, is supplied with this to booster 20 suitable
The exhaust of equivalent, and effectively use the control of power turbine 30.Extraction flow control is after step S7 or step S9
Perform.That is, extraction flow control is only performed in the state that open and close valve 51 is opened.Furthermore it is possible to be judged whether by scavenging pressure
The exhaust of appropriate amount can be supplied to booster 20.That is, it can interpolate that out supply to booster when scavenging pressure is higher than setting
The amount of 20 exhaust is superfluous, can interpolate that out that supply is not enough to the capacity of booster 20 when scavenging is forced down in setting.
First, control device 60 sets the scope of appropriate scavenging pressure（Step S11）.Herein, Fig. 4 shows appropriate
The chart of the scope of scavenging pressure.Fig. 4 transverse axis is engine load, and the longitudinal axis is scavenging pressure.In figure in two straight lines, top
Straight line represents upper limit scavenging pressure, and the straight line of lower section represents lower limit scavenging pressure.The part being clipped between two straight lines is appropriate
The scope of scavenging pressure.For example, as shown in figure 4, being L in engine load1When, lower limit scavenging pressure is PL, upper limit scavenging pressure is PH。
Lower limit scavenging pressure and upper limit scavenging are different according to engine load difference at all, are set as carrying as engine load increases
It is high.In actual step S11, the scope of appropriate scavenging pressure is calculated using the mathematical expression for the straight line for representing Fig. 4.
Then, whether control device 60 judges the actual scavenging pressure obtained in step sl in proper range（Step
S12）.Namely it is decided that whether actual scavenging pressure is more than the lower limit scavenging pressure set in step S11 and is less than upper limit scavenging pressure.
When scavenging pressure is located in proper range（"Yes" in step S12）, maintain the aperture of variable-nozzle 32（Step S13）, it is back to step
Rapid S1.Because even if not changing the aperture of variable-nozzle 32, the exhaust of appropriate amount can also supplied to booster 20.Also, such as
Upper described, when the aperture of regulation variable-nozzle 32 makes the exhaust of appropriate amount supply to booster 20, power turbine 30 is inevitable
Efficiently drive.
On the other hand, if scavenging pressure is not in proper range（"No" in step S12）, then judge that actual scavenging pressure is
It is no to be more than proper range（Step S14）.Namely it is decided that whether actual scavenging pressure is more than upper limit scavenging pressure.It is more than in scavenging pressure suitable
When scope（"Yes" in step S14）, increase the aperture of variable-nozzle 32（Step S15）, it is back to step S1.In the situation
Under, the exhaust needed for being flowed into booster 20 above, therefore perform the aperture of increase variable-nozzle 32 and reduce inflow booster
The control of the amount of the exhaust of 20 sides.That is, supply is reduced to the amount of the exhaust of booster 20 relatively from the discharge of engine main body 10
The ratio of capacity.If also, being controlled like this, the exhaust of appropriate amount, therefore power can be supplied to booster 20
Turbine 30 is also inevitable efficiently to be driven.
In step S14, when being determined as that actual scavenging pressure is not more than proper range（The "No" in step S14）, subtract
The aperture of small variable-nozzle 32（Step S16）, it is back to step S1.In this case, actual scavenging pressure is not more than appropriate model
Enclose, therefore actual scavenging pressure is less than proper range（Less than lower limit scavenging pressure）.Then, the amount being vented in booster 20 is not
Foot, therefore perform the aperture for reducing variable-nozzle 32 and increase the control of the amount for the exhaust for flowing into the side of booster 20.That is, supply extremely
The amount of the exhaust of booster 20 increases relative to the ratio of the amount for the exhaust discharged from engine main body 10.If also, like this
It is controlled, then the exhaust of appropriate amount can be supplied to booster 20, therefore also certainty efficiently drives power turbine 30.
As described above, being formed as structure according to the engine system 100 of this embodiment：Possesses the pumping He of pipe arrangement 44
Extraction valve 52, opens extraction valve 52 when open and close valve 51 is closed and forms the circulation stream by the gas of power turbine 30.Cause
This, when open and close valve 51 is closed, even if power turbine 30 is driven by bent axle 11, the front and rear pressure difference of power turbine 30 also will not be excessive
Increase, can suppress to produce excessive load in engine main body 10.
Also, the variable-nozzle 32 being had according to the engine system 100 of this embodiment by power turbine 30 is not only
The efficiency of power turbine 30 can be improved, and the amount of the exhaust supplied to booster 20 can be adjusted.It therefore, it can seek hair
The overall control of motivation system 100 and the simplification of structure.
