To prevent that surge occurs in operational process.
Step S40: when the current air inflow is greater than the default Surging flow, aperture regulation instruction, and root are generated
It instructs the current aperture regulation of default exhaust gas by-pass valve according to the aperture regulation to the first default aperture, to realize turbocharging
Regulation against surge.
It is understood that the effect of default exhaust gas by-pass valve is the air inlet pressure in the default inlet manifold for adjust engine
Power, also, control turbocharger and do not exceed the speed limit.With the revolving speed of engine and being gradually increased for load, exhaust gas by-pass valve is preset
Aperture be also gradually increased so that can be by-pass out by default exhaust gas by-pass valve in exhausting waste gas, weaken exhaust gas and push whirlpool

Further, after the step S10, the turbocharging method further include:
Step S101: the current pressure is compared with preset pressure.
In the current pressure and the preset pressure difference, step S20 is executed.
It is understood that the current pressure that can add default inlet manifold operates compared between preset pressure, when
Preceding pressure can also be denoted as current admission pressure, and preset pressure can also be denoted as default admission pressure.When real-time admission pressure is that this is pre-
If when admission pressure, it is believed that turbocharger at this time does not have the risk of surge.
It should be understood that subsequent anti-surge control will be executed if admission pressure is not the default admission pressure in real time
System strategy.
Further, it is described the current pressure is compared with preset pressure after, the turbocharging method is also
Include:
When the current pressure is identical as the preset pressure, generates aperture and maintain instruction, and tieed up according to the aperture
Hold the current aperture that instruction keeps the default exhaust gas by-pass valve.
It is understood that when real-time admission pressure is the default admission pressure, Given this when turbocharger do not have
There is the risk of surge, the aperture of default exhaust gas by-pass valve can not be changed.
The comparison operation for admission pressure is introduced in the present embodiment, to improve the control efficiency of anti-surge.Do not having
When the risk of surge, the aperture of default exhaust gas by-pass valve is not changed.
It is the flow diagram of turbocharging method 3rd embodiment of the present invention referring to Fig. 5, Fig. 5, based on shown in above-mentioned Fig. 4
Second embodiment, propose the 3rd embodiment of turbocharging method of the present invention.

Step S401: when the current air inflow is greater than the default Surging flow, aperture regulation instruction is generated.
It should be understood that the air inlet at default inlet manifold can be influenced in view of the aperture for changing default exhaust gas by-pass valve
Pressure, admission pressure can promote the generation of surge phenomenon, and by the aperture by adjusting default exhaust gas by-pass valve in the present embodiment
To evade surge phenomenon.
Step S402: according to the aperture regulation instruction by the current aperture regulation of default exhaust gas by-pass valve to it is described pre-
If the corresponding target aperture of pressure, the current pressure is adjusted to the preset pressure to realize.
It is understood that as the adjusting behavior of anti-surge, it can be specifically, for example, presetting the reality in inlet manifold
When border air inflow is greater than the minimum surge flow under current pressure ratio environment, i.e. M0 > Mc can carry out the adjusting of anti-surge, and consider
To default exhaust gas by-pass valve aperture and default inlet manifold admission pressure between there is relevances, it is believed that a certain number
The admission pressure of value will correspond to an opening value.
It should be understood that preset pressure herein will correspond to target aperture, in other words, when default exhaust gas by-pass valve
When aperture is adjusted to the numerical value of target aperture, the admission pressure of default inlet manifold will be affected as the preset pressure.And work as
When current pressure is adjusted to preset pressure, it is believed that turbocharger at this time does not have the risk of surge.
Further, it is described according to the aperture regulation instruction by the current aperture regulation of default exhaust gas by-pass valve to institute
The corresponding target aperture of preset pressure is stated, the current pressure is adjusted to the preset pressure to realize, is specifically included:
The current aperture of default exhaust gas by-pass valve is adjusted according to aperture regulation instruction, and it is pre- to return to the execution acquisition
If the step of current pressure and Current Temperatures of inlet manifold, until when the current pressure is identical as the preset pressure,
Stop the adjusting for the default exhaust gas by-pass valve to operate, the current aperture regulation is extremely corresponding with the preset pressure
Target aperture and the current pressure be adjusted to the preset pressure.
It is understood that the adjusting behavior as the anti-surge is in detail, can constantly be adjusted by circulatory monitoring operation
The current aperture of default exhaust gas by-pass valve is saved, so that the current pressure of default inlet manifold constantly approaches the numerical value of preset pressure,
Until it is equal with preset pressure, it can stop adjusting operation at this time.
In the concrete realization, the current pressure for presetting inlet manifold can be denoted as P0, and preset pressure can be denoted as P, and P0 is not equal to
P.After having adjusted the current aperture of default exhaust gas by-pass valve, the default current pressure of inlet manifold this moment of monitoring, P0 can return to
Numerical value changed.If P0 is still not equal to P at this time, it can continue to adjust default exhaust gas by-pass valve, again return to monitoring
The current pressure of default inlet manifold this moment.If the P0 after second of adjusting has been equal to P, the operation that circulation is adjusted can be stopped,
Keep the aperture of default exhaust gas by-pass valve constant, and current aperture this moment is also adjusted to target corresponding with preset pressure P
Aperture.
Further, after the step S30, the turbocharging method further include:
When the current air inflow is less than or equal to the default Surging flow, surge decision instruction is generated, according to institute
It states surge decision instruction and adjusts the current aperture of the default exhaust gas by-pass valve to the second default aperture, to enter standby mode.
In the concrete realization, when current air inflow is less than or equal to default Surging flow, i.e. M0≤Mc, at this time it is believed that
Turbocharger has surge risk, and ECU is by generating the controllable current aperture for presetting exhaust gas by-pass valve of surge decision instruction
Variation is maximum opening, that is, controls default exhaust gas by-pass valve moment holding standard-sized sheet, meanwhile, turbocharger will enter standby mode
It stops working.
Further, before the step S30, the turbocharging method further include:
Obtain current pressure ratio；
Corresponding default Surging flow, the default asthma are inquired in default surge mapping relations according to the current pressure ratio
It include the corresponding relationship between pressure ratio and Surging flow in mapping relations of shaking.
In the concrete realization, it can also be previously stored with default surge mapping relations in ECU, remember in default surge mapping relations
Record has the corresponding relationship between pressure ratio and Surging flow, and turbocharging can be used as the form of expression of default surge mapping relations
Device surge line.
It is understood that the current pressure ratio environment by determining turbocharger, can constantly change corresponding default asthma
