As Figure 2-3, engine aspirating system, including electric booster 3, bypass line 2 and controller 5, electronic increasing
Depressor 3 is in parallel with bypass line 2, and controller is used to control the opening and closing of electric booster 3 and bypass line 2；
When engine speed is more than the first setting speed, the control electric booster 3 of controller 5 starts, and bypass line 2 is closed
Close；
When engine speed is more than the second setting speed, the control electric booster 3 of controller 5 is closed, bypass line 2 dozens
Open；
First setting speed is less than the second setting speed.
In the present embodiment, the first setting speed is 1000r/min.When engine reaches the first setting speed, to start
Machine low-speed running state, now needs the air inflow for increasing engine by electric booster 3, lifts engine in low speed shape
Moment of torsion and power under state.
And when the rotating speed of engine is less than 1000r/min, usually idling and low speed starting stage, to torque output
Require than relatively low, it is not necessary to increase extra air inflow to lift torque output, therefore electric booster need not start.
It is high engine speeds operating condition when engine reaches the second setting speed, the now moment of torsion and work(of engine
Rate is enough, it is no longer necessary to increase air inflow by electric booster 3.Therefore, now electric booster 3 closed, opens other
Siphunculus road 2, reduce admission pressure loss, for reducing the high rotating speed of engine under pressure drop.
Second setting speed is different according to the setting value of different displacements engine, and concrete numerical value is needed according to electronic
The pressure drop that produces with its own of flow that booster is produced weighing, when the underfed of booster generation is overcoming electronic increasing
Depressor pressure drop at high speed, now selects to close electric booster, opens bypass line.
In the present embodiment, electric booster 3 has the requirement of minimum discharge, and concrete minimum discharge requires to need according to engine
Discharge capacity and demand are determining.Electric booster is lightweight by high-temperature resistance plastice material is made.
Due to increased electric booster 3 and bypass line 2 in parallel in engine aspirating system in the present embodiment, when
During time of engine low speed, electric booster 3 starts, and bypass line 2 is closed, and for increasing the air inflow of engine, improves and sends out
Moment of torsion and power during motivation low speed；When the rotating speed of engine is lifted to setting speed, electric booster 3 is closed, bypass pipe
Road 2 is opened, for reducing the high rotating speed of engine under pressure drop.Additionally, the simple structure of the present embodiment, low cost.
