Abstract
The invention discloses a vacuum actuator power source of a variable length intake manifold. The vacuum actuator power source is characterized by being provided with a vacuum tank, wherein the first interface on the vacuum tank is connected to an electromagnetic valve through a gas source pipe, and the electromagnetic valve is connected in series between a vacuum actuator and the gas source pipe; and the second interface on the vacuum tank is connected with a one-way valve through a gas pipe, the one-way valve is connected in series between the gas pipe and the engine intake manifold, and the one-way valve conducts the airflow flowing out of the vacuum tank and cuts off the gas reflowing to the vacuum tank. The negative pressure generated in the engine intake manifold by air suction of a cylinder when an engine works is used as the power source of the vacuum actuator, and external power is not needed, so the space is greatly saved, the weight is lightened, the cost is reduced, and adverse factors caused by the external vacuum power source are effectively weakened.
Description
Technical field
The present invention relates to engine accessory power rating, the setting of the vacuum actor power source of a kind of variable-length intake manifold of more specifically saying so.
Background technique
The output characteristics of naturally aspirated engine such as power, moment of torsion, oil consumption are closely related with the pipe range and the rotating speed of intake manifold to a great extent, and in general, when intake manifold was longer, middle low-speed performance performance better; More in short-term, the high speed performance performance better in intake manifold.In order to take into account this two states, development in recent years goes out variable-length intake manifold, and long tube and short tube are realized switching on certain specified point of middling speed, to guarantee optimized output characteristics.Use vacuum actor to be executive component in the handoff procedure, with the switching between vacuum actor promotion changing valve realization long tube and the short tube.
In the prior art, the way that is equipped with the routine of power source for vacuum actor spare is the vacuum pump that a band vacuum tank is set separately, is used for producing vacuum.But in concrete the application, the mode in this set extrinsic motive source is not only because of increasing cost, more brings adverse factors because of interpolation equipment takes up space and gains in weight.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology deficiency, a kind of vacuum actor power source of variable-length intake manifold is provided, cylinder suction produces negative pressure for doing moving source when utilizing engine operation in intake manifold, thereby simplify the configuration of external vacuum power source, reduce volume, weight reduction, weaken because the unfavorable factor that the external vacuum power source of configuration is brought.
Technical solution problem of the present invention adopts following technological scheme:
The invention discloses a kind of vacuum actor power source of variable-length intake manifold, its structural feature is that a vacuum tank is set, first interface is connected to solenoid valve by the source of the gas pipe on the described vacuum tank, and described solenoid valve series connection is arranged between vacuum actor and the source of the gas pipe; Second interface connects one-way valve by pneumatic tube on the described vacuum tank, described one-way valve is connected in series between pneumatic tube and the engine intake manifold, described one-way valve is on state for the air-flow that flows out from vacuum tank, is off state for the gas that refluxes in vacuum tank.
The structural feature of the vacuum actor power source of variable-length intake manifold of the present invention is that also described vacuum tank and engine intake manifold are integrated on the same body.
Compared with the prior art, beneficial effect of the present invention is embodied in:
When 1, the present invention utilizes engine operation, the negative pressure that produces in starting intake manifold because of cylinder suction is as the power source of vacuum actor, need not to be equipped with separately extrinsic motive, saved space and weight reduction greatly, reduced cost, effectively weakened because the unfavorable factor that the external vacuum power source of configuration is brought.
2, the present invention is integrated in vacuum tank and engine intake manifold on the same body, makes simple compact, the good integrity of complete machine structure.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Number in the figure: 1 engine intake manifold; 2 pneumatic tubes; 3 source of the gas pipes; 4 one-way valves; 5 vacuum tanks; 6 vacuum actors; 7 solenoid valves.
Embodiment
Referring to Fig. 1, in the present embodiment, the integrated vacuum tank 5 that is provided with on the body of engine intake manifold 1, first interface is connected to solenoid valve 7 by source of the gas pipe 3 on the vacuum tank 5, and solenoid valve 7 series connection are arranged between vacuum actor 6 and the source of the gas pipe 3; Second interface connects one-way valve 4 by pneumatic tube 2 on the vacuum tank 5, and one-way valve 4 is connected in series between pneumatic tube 2 and the engine intake manifold 1; One-way valve 4 is on state for the air-flow that flows out from vacuum tank 5, is off state for the gas that refluxes in vacuum tank 5.
During engine operation, engine cylinder produces negative pressure, attract air to participate in burning through pneumatic tube 2, one-way valve 4 and engine intake manifold 1 flow direction engine cylinder successively from vacuum tank 5, so continuous effect just makes and formed a vacuum source in vacuum tank 5.When vacuum final controlling element 6 needed action, solenoid valve 7 was opened, and the negative pressure in the vacuum tank 5 drives vacuum actor 6 by source of the gas pipe 3 and produces action.
Claims (2)
1. the vacuum actor power source of a variable-length intake manifold, it is characterized in that being provided with a vacuum tank (5), last first interface of described vacuum tank (5) is connected to solenoid valve (7) by source of the gas pipe (3), and described solenoid valve (7) series connection is arranged between vacuum actor (6) and the source of the gas pipe (3); Last second interface of described vacuum tank (5) connects one-way valve (4) by pneumatic tube (2), described one-way valve (4) is connected in series between pneumatic tube (2) and the engine intake manifold (1), described one-way valve (4) is on state for the air-flow that flows out from vacuum tank (5), is off state for the gas that refluxes in vacuum tank (5).
