Detailed description of the invention

An embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.

This utility model embodiment as it is shown in figure 1, include covers 1, piston 2, air inlet pipe joint 3, axle 4, spring 5, valve block 6, capping 7, cleaner 8, copper sheathing 9, nut 10, master control pipe joint 11, housing 12；The additional air intake installation of this utility model includes envelope Lid 1, piston 2, air inlet pipe joint 3, axle 4, spring 5, valve block 6, capping 7, cleaner 8, master control pipe joint 11, housing 12；Housing 12 sides be master control air chamber, opposite side be inlet plenum；Between housing 12 master control air chamber and inlet plenum, there is dead eye；Copper sheathing 9 It is fastenedly connected with the dead eye of housing 12；The copper sheathing 9 that axle 4 is fastenedly connected with housing 12 dead eye is slidably matched, can be straight along copper sheathing 9 Line moves back and forth, and seals off master control air chamber and inlet plenum；Piston 2 is arranged in the master control air chamber of housing 12, and piston 2 is installed In axle 4 end, piston 2 is fastenedly connected on axle 4 by nut 10；Piston 2 is slidably matched with master control air chamber；At housing 12 master control gas Indoor, the housing between piston 2 and dead eye has steam vent；Capping 1 is arranged on the end of housing 12 master control air chamber；Master control Pipe joint 11 is installed and is connected to cover on 1, pipeline connection master control air chamber；Air inlet pipe joint 3 is connected with the inlet plenum of housing 12； Spring 5, valve block 6 are arranged in the inlet plenum of housing 12, and spring 5 precommpression is arranged between axle 4 and valve block 6, valve block 6 and axle 4 End is fastenedly connected；Capping 7 is arranged on the inlet plenum end of housing 12；Cleaner 8 is connected with the inlet plenum of housing 12.

As in figure 2 it is shown, this utility model air inlet pipe joint 3, master control pipe joint 11 and engine throttle air inlet discrimination behind the door Pipe pipeline connects；Engine ECU electrically connects with air inlet pressure sensor MAP.

As shown in Figure 1 and Figure 2, when electromotor accelerates, the master control pipe joint 11 pipeline internal gas pressure connecting inlet manifold increases Greatly, gas entrance master control air chamber pressure promotes piston 2, axle 4, valve block 6 to move right；Shape between the housing 12 of valve block 6 and inlet plenum Become pore channel, airway open；Air is by the pore channel between the housing 12 of cleaner 8, valve block 6 and inlet plenum, air inlet pipe Joint 3 enters electromotor；Air inlet pressure sensor MAP sends a signal to Engine ECU；Engine ECU passes according to admission pressure The output of sensor MAP signal increases distributive value command signal, and supercharging promotes engine power；Due to the basis in original air inflow On the most additional increase air inflow, supplement sufficient oxygen, promote that fuel oil fully burns, reach to promote power, fuel-economizing, reduce tail gas The effect of discharge standard.

As it is shown in figure 1, when engine retard idling, air throttle moment completely closes, produce maximum true in inlet manifold Reciprocal of duty cycle；Negative pressure of vacuum is produced, by negative pressure of vacuum effect, piston 2 band moving axis in connecting master control pipe joint 11 pipeline of inlet manifold 4, valve block 6 is moved to the left, and contacts sealing between valve block 6 with the housing 12 of inlet plenum, and air flue is closed；Electromotor will not obtain adding into Gas, plays fruit in fuel efficiency；Engine speed rapidly returns back to former car idling mode, does not affect brake system simultaneously；When electromotor puts out During fire, spring force 5 promotes valve block 6, axle 4, piston 2 to move right, and forms pore channel between the housing 12 of valve block 6 and inlet plenum, Airway open.

This utility model supercharging principle is:

After this utility model is owing to being arranged on air throttle, air inflow will not be affected because of the bottleneck effect of air throttle, Increase throttle reaction simultaneously；If throttle opening is 1/3, then air inflow has a relative number value according to rotating speed, and This device can increase again a quantitative value, is equivalent to the proportional increasing of bore of air throttle；Throttle degree of reaction can be increased, simultaneously Promote the rotating speed of electromotor, make electromotor export high pulling torque in advance.

Especially middle and slow speed of revolution district, this utility model can improve volumetric efficiency, improves power and is obtaining verification experimental verification.Due to After it is arranged on air throttle, objectively equal to increasing air throttle sectional area, reduce intake resistance, be conducive to improving high speed special Property.
