When cooler for recycled exhaust gas works, when gas is entered in bypass pipe 11 by electric EGR valve escape pipe 12, such as valve element 21
Bottom 22 in bypass pipe 11, then the inlet end for the finned cooling airway of the entrance of upper end 23 that gas can only be through bypass pipe 11,
Enter air throttle after the cooling of finned cooling airway, then by the outlet side 7 of cooler for recycled exhaust gas, because passing through EGR valve escape pipe
Waste gas all cool down, so the cooling effectiveness of gas is maximum under state.
It is evacuated to by-passing valve 5, the volume of epithelium and upper lid is diminished, be i.e. epicoele volume diminishes, now spring-compressed, drives
Center-pole 20 and valve element 21 move in bypass pipe 11, valve element 21 is placed in the upper end 23 of bypass pipe 11；Now, gas is through EGR valve
After escape pipe 12 enters bypass pipe 11, air throttle is directly flowed into by the bottom 22 of bypass pipe 11, now gas is without cooler for recycled exhaust gas
4 coolings, the cooling effectiveness of this state gas are minimum.
When needing to adjust cooling effectiveness, the rate of air sucked in required of by-passing valve 5 is adjusted, shrinks spring 19, you can control valve element exists
Position in bypass pipe, so as to control throughput of the gas by the upper end 23 of bypass pipe 11 and bottom 22.Set on by-passing valve 5
The position sensor 15 put, the position that can be in precision control valve core 21 in bypass pipe 11, so as to realize accurate control cooling
The purpose of efficiency.
In the present invention, air throttle is reluctance type electronic throttle 3, and reluctance type electronic throttle is carried out using reluctance machine
Driving, simple in construction, cost is low, and control accuracy is high.
The structure of reluctance type electronic throttle is as shown in fig. 7, comprises be provided with the throttle body 40 of gas passage, air throttle
The inlet end of body 40 connects with the outlet side 7 of cooler for recycled exhaust gas；Uprush direction is provided with the gas passage of throttle body 40
Air throttle valve rod 41, the valve block 42 that control gas passage opens and closes is fixedly installed on air throttle valve rod 41.Throttle body 40
One reluctance machine 43, the top of the output axis connection throttler valve bar 41 of reluctance machine 43 are set on outer wall；Throttler valve
The bottom of bar 41 is stretched out outside throttle body 40 and positioned by being arranged on the Outer Bottom Plating of throttle body 40, bottom plate and air throttle valve rod 41
Bottom is connected by bearing.
The bottom outer cover that air throttle valve rod 41 stretches out throttle body 40 is equipped with sleeve, and sleeve is located at throttle body 40 and bottom
The limiting plate 47 being slidably matched with bottom plate is additionally provided between plate, on bottom plate, limiting plate is fixedly connected with air throttle valve rod bottom.
Torsionspring 48 is provided between limiting plate 47 and sleeve, for resetting valve block 42；One end of torsionspring 48 is arranged on section
In hole 49 on valve body, the other end is arranged in the hole 50 on limiting plate, and valve block 42 can pass through the return pulling force of torsionspring 48
It is pulled to fully open position.
The coil 46 that reluctance machine 43 includes shell and ring type stator 45 in shell, is wound on stator body
With the rotor 44 for being arranged on side corresponding with coil on stator body, as shown in Figure 8；Rotor 44 connects with the top of air throttle valve rod 41
Connect.The rotation of rotor 44 can be rotated by valve rod 41 with moving valve plate 42, realize the opening and closing of reluctance type electronic throttle 3
Function.
In the reluctance type electronic throttle course of work, when not giving the coil 46 of reluctance machine 43 to power, whole motor
Without magnetic field, rotor 44 is pulled to such as Fig. 7 positions by the pretightning force of torsionspring 48, and now valve block 42 is in fully open position.
Coil 46 to reluctance machine 43 is powered, and reluctance machine just produces torsion magnetic field force, now the torsion of rotor
Torque is maximum, and the torsional moment of torsionspring is minimum, therefore rotor starts to rotate, and magnetic field is produced in stator 45 makes rotor 44, valve rod
41 and valve block 42 rotate；With the deflection of rotor, reluctance machine torsional moment is less and less, and the torsional moment of torsionspring is got over
Come bigger, when two torques are equal in magnitude, rotor stress reaches balance, is not rotated further by, and realizes the closing function of air throttle.
When reducing the supply current of reluctance machine 43, the torsional moment of reluctance machine 43 synchronously reduces, rotor 44,
Valve rod 41 and valve block 42 invert under the flywheel moment effect of torsionspring 48, so as to play control reluctance type electronic throttle 3
The effect of aperture.When the supply current of reluctance machine 43 is in a certain fixed value, the torsional moment of reluctance machine 43 with
The torsional moment of torsionspring 48 is equal, i.e., rotor 44 and torsionspring 48 are in a certain balance, are not rotated further by, even if magnetic resistance
Formula electronic throttle 3 is stable to be in a certain aperture；Change the supply current of reluctance machine 43, rotor 44 and the weight of torsionspring 48
Newly reach balance, so that reluctance type electronic throttle 3 is stable to be in a certain new aperture；Realize reluctance type electronic throttle
The Linear Control of door 3.
In real work, engine section waste gas is entered the present invention after electric EGR valve controls by EGR escape pipes
In bypass type cooler, by the exhausted air quantity that need to cool down of by-passing valve control, after reaching required cooling effectiveness, waste gas enters solar term
Door body；Engine charge enters engine intake manifold with after cooler cooling and the waste gas after throttle control mix.
