Description
Technical field
This utility model relates to engine pressure control system field, particularly to one for gasoline supercharging engine pressure
The constant-current stabilizer of Force control system.
Background technology
Along with quickening and the convenience of trip of people's rhythm of life, increasing people have a mind purchase passenger car ride instead of walk.
In order to meet the strictest discharge standard, Automobile Enterprises needs constantly to carry out technological improvement, and turbocharger is for bavin
Oil, the supporting environmental protection of gasoline power plant, energy-saving high-tech product, it can improve the working condition of electromotor well,
Thus meet high-level emission request.Supercharging is that electromotor meets more maximum discharge standard and the technology that must take, discharge mark
Development for supercharger industry is brought endless with the internationalization of technology and developing rapidly of automobile market by accurate requirement, market
Potentiality.
Engine with supercharger typically each uses exhaust gas bypass technology, valve closing of exitting when low speed and high pulling torque operating mode, fills
Divide the rotating speed utilizing exhaust energy to improve turbocharger, it is ensured that the air capacity needed for electromotor and pressure ratio；Electromotor turns at height
Venting valve opening by-passing part exhaust energy when speed, declared working condition, it is ensured that turbocharger does not exceeds the speed limit.
After petrol engine turbocharging, exhaust gas bypass technical foundation adds PWM valve control, according to electromotor
The nominal data of ECU obtains nonlinear duty cycle signals, then controls PWM valve with duty cycle signals, PWM valve control entrance and hold
The boost pressure of row device so that the aperture of venting valve can be adjusted according to the actual demand of operating point, thus controls turbine
The rotating speed of supercharger, obtains required boost pressure, to reach the matched well of turbocharger and electromotor, meets gasoline
The power performance of electromotor and economic performance.PWM valve is that the reciprocating motion by certain frequency reaches to control output to performing
The air pressure size of device work air cavity, thus brings a problem, and it is to have that PWM valve exports the work pressure of air cavity of executor
Certain pulse ripple.And gasoline engine engine with supercharger is the softest due to needs often executor's contained spring of match control,
Under such a pulse ripple, it sometimes appear that the instability of whole pressure charging system so that it is input to the air pressure fluctuation of electromotor,
Engine performance is unstable.
Utility model content
The purpose of this utility model is the above-mentioned deficiency for prior art and defect, it is provided that a kind of for gasoline supercharging
The constant-current stabilizer of engine pressure control system, to solve the problems referred to above.
This utility model is solved the technical problem that to realize by the following technical solutions:
A kind of constant-current stabilizer for gasoline supercharging engine control pressurer system, it is characterised in that include being bushed in PWM
The current stabilization part in rubber tube between valve outfan and executor's valve connecting line, the middle part of described current stabilization part is provided with at least
One current stabilization hole for fluctuated gases process.
In a preferred embodiment of the present utility model, the cross sectional shape in described current stabilization hole is circular or square.
In a preferred embodiment of the present utility model, the two ends outer peripheral face of described current stabilization part is set to tapering transition face
Structure.
In a preferred embodiment of the present utility model, described current stabilization part uses engineering plastics or metalwork to make.
Owing to have employed technical scheme as above, the beneficial effects of the utility model are: this utility model is by PWM
It is disposed with current stabilization part, when the gas of fluctuation is passing through current stabilization in rubber tube between valve outfan and executor's valve connecting line
Processed behind the current stabilization hole of part steadily thus being smoothly transported to executor and work air cavity, the work of valve of so exitting becomes
Stable, improve electromotor job stability, improve the service life of whole engine system.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under
Face is expanded on further this utility model.
Shown in Figure 1, a kind of constant-current stabilizer for gasoline supercharging engine control pressurer system includes being bushed in PWM
The current stabilization part 100 in rubber tube 30 between valve outfan 10 and executor's valve 20 connecting line, the middle part of current stabilization part 100 sets
It is equipped with at least one current stabilization hole 110 for fluctuated gases process.
Seeing shown in Fig. 2 and Fig. 3, the cross sectional shape in the current stabilization hole 110 in the present embodiment is circular, and current stabilization part 100
Middle part has been arranged side by side two current stabilization holes 110.Certainly, the middle part of the current stabilization part 100 in the present embodiment can also only arrange one
Cross section is square current stabilization hole 110 (as shown in Figure 4).
For convenience current stabilization part 100 is bushed in the rubber between PWM valve outfan 10 and executor's valve 20 connecting line
In sebific duct 30, the two ends outer peripheral face of the current stabilization part 100 in the present embodiment is set to tapering transition face structure 120.
