Description
Technical field
The present invention relates to engine pressure control system field, start for gasoline supercharging particularly to one
The constant-current stabilizer of machine control pressurer system.
Background technology
Along with quickening and the convenience of trip of people's rhythm of life, increasing people have a mind purchase riding
Car is ridden instead of walk.In order to meet the strictest discharge standard, Automobile Enterprises needs constantly to carry out technology and changes
Entering, turbocharger is for the supporting environmental protection of diesel oil, gasoline power plant, energy-saving high-tech product,
It can improve the working condition of engine well, thus meets high-level emission request.Supercharging is
The technology that engine meets more maximum discharge standard and must take, the requirement of discharge standard, market and technology
Internationalization and developing rapidly of automobile market the development for booster industry is brought endless potentiality.
Engine with supercharger typically each uses exhaust gas bypass technology, valve of exitting when low speed and high pulling torque operating mode
Close, make full use of exhaust energy and improve the rotating speed of turbocharger, it is ensured that the air capacity needed for engine
And pressure ratio；Engine is exitted when high rotating speed, declared working condition valve opening by-passing part exhaust energy, protects
Card turbocharger does not exceeds the speed limit.
After petrol engine turbocharging, exhaust gas bypass technical foundation adds PWM valve control, root
Obtain nonlinear duty cycle signals according to the nominal data of Engine ECU, then control PWM with duty cycle signals
Valve, is controlled to enter the boost pressure of actuator by PWM valve so that the aperture of venting valve can be according to operating mode
The actual demand of point is adjusted, thus controls the rotating speed of turbocharger, obtains required boost pressure,
To reach the matched well of turbocharger and engine, meet petrolic power performance and warp
Ji performance.PWM valve is that the reciprocating motion by certain frequency reaches to control output to actuator work air cavity
Air pressure size, thus bring a problem, PWM valve exports the pressure of actuator work air cavity and is
There is certain pulse ripple.And gasoline engine engine with supercharger is due in the needs often actuator of match control
Portion's spring is the softest, under such a pulse ripple, it sometimes appear that the instability of whole pressure charging system,
Making to be input to the air pressure fluctuation of engine, engine performance is unstable.
Summary of the invention
Present invention aims to above-mentioned deficiency and the defect of prior art, it is provided that a kind of for supercharging
The constant-current stabilizer of petrol engine control pressurer system, to solve the problems referred to above.
Technical problem solved by the invention can 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
The current stabilization part being bushed in the rubber tube between PWM valve output and actuator valve connecting line, described
The middle part of current stabilization part is provided with at least one current stabilization hole for fluctuated gases process.
In a preferred embodiment of the invention, the cross sectional shape in described current stabilization hole is circular or square.
In a preferred embodiment of the invention, the two ends outer peripheral face of described current stabilization part is set to taper
Cross face structure.
In a preferred embodiment of the invention, described current stabilization part uses engineering plastics or metalwork system
Become.
Owing to have employed technical scheme as above, the beneficial effects of the present invention is: the present invention is by PWM
It is disposed with current stabilization part, when the gas of fluctuation in rubber tube between valve output and actuator valve connecting line
Body is processed steady after by the current stabilization hole of current stabilization part, thus is smoothly transported to actuator work air cavity,
So work of venting valve becomes stable, improves engine job stability, improves whole starting
The service life of machine system.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be readily apparent from
Solve, the present invention is further elucidated below.
Shown in Figure 1, a kind of constant-current stabilizer for gasoline supercharging engine control pressurer system includes
The current stabilization being bushed in the rubber tube 30 between PWM valve output 10 and actuator valve 20 connecting line
Part 100, the middle part of current stabilization part 100 is provided 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
The middle part of current stabilization part 100 has been arranged side by side two current stabilization holes 110.Certainly, the current stabilization part in the present embodiment
It is square current stabilization hole 110 (as shown in Figure 4) that the middle part of 100 can also only arrange a cross section.
For convenience current stabilization part 100 is bushed in PWM valve output 10 and actuator valve 20 connecting tube
