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, controller 5 controls electric booster 3 and starts, and bypass line 2 closes
It closes；
When engine speed is more than the second setting speed, controller 5 controls electric booster 3 and closes, and bypass line 2 is beaten
It opens；
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 needs to increase by electric booster 3 at this time the air inflow of engine, promotes engine in low speed shape
Torque and power under state.
And when the revolving speed of engine is lower than 1000r/min, usually idling and low speed starting stage, torque is exported
It is required that it is relatively low, it does not need to increase additional air inflow to promote torque output, therefore electric booster does not need to start.
It is high engine speeds operating condition, the at this time torque and function of engine when engine reaches the second setting speed
Rate is enough, it is no longer necessary to increase air inflow by electric booster 3.Therefore, electric booster 3 is closed at this time, is opened other
Admission pressure loss is reduced, for reducing the pressure drop under the high revolving speed of engine in siphunculus road 2.
Second setting speed is different according to the setting value of different displacements engine, and specific value is needed according to electronic
The pressure drop that generates with its own of flow that booster generates is measured, when the underfed of booster generation is to overcome electronic increasing
The pressure drop of depressor at high speed, electric booster is closed in selection at this time, opens bypass line.
In the present embodiment, electric booster 3 has the requirement of minimum discharge, and specific minimum discharge requires to need according to engine
Discharge capacity and demand are determined.Electric booster is light-weight by high-temperature resistance plastice material is made.
Due to increasing electric booster 3 and bypass line 2 in parallel in engine aspirating system in the present embodiment, when
When time of engine low speed, electric booster 3 starts, and bypass line 2 is closed, and for increasing the air inflow of engine, improves hair
Torque and power when motivation low speed；When the revolving speed of engine is promoted to setting speed, electric booster 3 is closed, bypass pipe
Road 2 is opened, for reducing the pressure drop under the high revolving speed of engine.In addition, the structure of the present embodiment is simple, at low cost.
In the present embodiment, as shown in Fig. 2, controller 5 adjusts turning for electric booster 3 also according to the aperture of air throttle
Speed, throttle opening is bigger, and the revolving speed of electric booster 3 is higher.
What throttle opening amount signal represented is the demand of air input of engine by air, and throttle opening is bigger, illustrates engine pair
The demand of air inflow is bigger, and power output desired by driver is bigger, and vice versa；The electric booster revolving speed the high, generates
Charge flow rate is big, meets the needs of engine is to air inflow and load.
In the present embodiment, engine rotational speed signal plays the work that control drives and bypass line booster opens and closes
With throttle opening amount signal then is used to adjust the revolving speed of electric booster.
Optionally, electric booster 3 includes driving circuit, and controller 5 controls electronic pressurization by control driving circuit
The revolving speed of device 3.

Optionally, controller 5 controls the opening and closing of bypass line 2 by operation control valve door.
In the present embodiment, as shown in Figure 1, electric booster 3 and bypass line 2 are located at air filter assembly 1 and engine charge
Between menifold 4.
In order to improve the durability of electric booster 3, need electric booster 3 being put into the clean of engine aspirating system
Side, to reduce dust influence, clean side refers to the gas outlet of air filter assembly 1 between the air intake of engine suction manifold 4
Pipeline.
Specifically, as shown in Figure 1, the air intake of electric booster 3 is connect with the gas outlet of air filter assembly 1, electronic pressurization
The gas outlet of device 3 is connect with the air intake of engine suction manifold 4, the air intake of bypass line 2 and the gas outlet of air filter assembly 1
Connection, the gas outlet of bypass line 2 is connect with the air intake of engine suction manifold 4.
As shown in figure 3, engine charge adjusting method, comprising the following steps:
Step S301: controller 5 receives engine rotational speed signal；
Step S302: when the engine operates with a low speed, controller 5 controls electric booster 3 and starts, and bypass line 2 is closed；
Here low-speed running refers to that the revolving speed of engine is greater than or equal to 1000r/min, but turns lower than the second setting
Speed.
Step S303: when high engine speeds operating, controller 5 controls electric booster 3 and closes, and bypass line 2 is opened；
Running at high speed here refers to that the revolving speed of engine is greater than or equal to the second setting speed.
Step S304: controller 5 receives throttle opening amount signal；
