During cooler for recycled exhaust gas work, when gas is entered in bypass tube 11 by electric EGR valve steam outlet pipe 12, as spool 21 is in the bottom 22 of bypass tube 11, then gas can only enter the inlet end of finned cooling airway through the upper end 23 of bypass tube 11, after finned cooling airway cooling, closure is entered again, because all being cooled by the waste gas of EGR valve steam outlet pipe, so the cooling effectiveness of gas is maximum under state by the outlet side 7 of cooler for recycled exhaust gas.
Bleed to bypass valve 5, make the smaller volume of epithelium and upper cover, be i.e. epicoele smaller volume, now spring-compressed, drive center-pole 20 and spool 21 to move in bypass tube 11, make spool 21 be placed in bypass tube 11 upper end 23; Now, gas enters after bypass tube 11 through EGR valve steam outlet pipe 12, and directly flow into closure by bypass tube 11 bottom 22, now gas cools without cooler for recycled exhaust gas 4, and the cooling effectiveness of this state gas is minimum.
When needs regulate cooling effectiveness, regulate the rate of air sucked in required of bypass valve 5, spring 19 is shunk, i.e. the position of controllable valve core in bypass tube, thus the throughput of gas through bypass tube 11 upper end 23 and bottom 22 can be controlled.The position transducer 15 that bypass valve 5 is arranged, can be in position in bypass tube 11 by precision control valve core 21, thus realize the object of accurate controlled cooling model efficiency.
In the present invention, closure is magnetoresistive type electronic throttle 3, and magnetoresistive type electronic throttle adopts reluctance machine to drive, and structure is simple, and cost is low, and control accuracy is high.
The structure of magnetoresistive type electronic throttle as shown in Figure 7, comprises the throttle body 40 being provided with gas channel, and the inlet end of throttle body 40 is communicated with the outlet side 7 of cooler for recycled exhaust gas; Be provided with the closure valve rod 41 in uprush direction in the gas channel of throttle body 40, closure valve rod 41 be fixedly installed the valve block 42 controlling gas channel and open and close.The outer wall of throttle body 40 is arranged a reluctance machine 43, the top of the output shaft connecting joint valve stem 41 of reluctance machine 43; The bottom of closure valve rod 41 stretches out that throttle body 40 is outer and by being arranged on throttle body 40 Outer Bottom Plating location, base plate is connected by bearing with closure valve rod 41 bottom.
The bottom outer cover that closure valve rod 41 stretches out throttle body 40 is equipped with sleeve, and sleeve, between throttle body 40 and base plate, base plate is also provided with the limiting board 47 be slidably matched with base plate, and limiting board is fixedly connected with closure valve rod bottom.Being provided with torsion spring 48 between limiting board 47 and sleeve, resetting for making valve block 42; One end of torsion spring 48 is arranged in the hole 49 on throttle body, and the other end is arranged in the hole 50 on limiting board, and valve block 42 is pulled to fully open position by torsion spring 48 return pulling force.
Reluctance machine 43 comprises shell and is positioned at the ring type stator 45 of shell, is wound on coil 46 on rotor and the rotor 44 being arranged on side corresponding with coil on rotor, as shown in Figure 8; Rotor 44 is connected with closure valve rod 41 top.The rotation of rotor 44 is with moving valve plate 42 to rotate by valve rod 41, realizes the opening and closing function of magnetoresistive type electronic throttle 3.
In magnetoresistive type electronic throttle working procedure, when powering to the coil 46 of reluctance machine 43, whole motor is without magnetic field, and rotor 44 is pulled to as Fig. 7 position by torsion spring 48 pretightening force, and now valve block 42 is in fully open position.
Be energized to the coil 46 of reluctance machine 43, reluctance machine just produces twisted magnetic field force, and now the torsional moment of rotor is maximum, and the torsional moment of torsion spring is minimum, therefore rotor starts to rotate, produce magnetic field in stator 45 and rotor 44, valve rod 41 and valve block 42 are rotated; Along with the deflection of rotor, reluctance machine torsional moment is more and more less, and the torsional moment of torsion spring is increasing, and when two moment equal and opposite in directions, rotor is stressed reaches balance, no longer rotates, and realizes the closing function of closure.
When reducing the supply current of reluctance machine 43, the torsional moment of reluctance machine 43 synchronously reduces, and rotor 44, valve rod 41 and valve block 42 reverse under the flywheel moment effect of torsion spring 48, thus plays the effect controlling magnetoresistive type electronic throttle 3 aperture.When the supply current of reluctance machine 43 is in a certain fixed value, the torsional moment of reluctance machine 43 is equal with the torsional moment of torsion spring 48, namely rotor 44 and torsion spring 48 are in a certain balance, all no longer rotate, even if magnetoresistive type electronic throttle 3 is stable be in a certain aperture; Change the supply current of reluctance machine 43, rotor 44 and torsion spring 48 reach balance again, thus make that magnetoresistive type electronic throttle 3 is stable is in a certain new aperture; Namely the linearity control of magnetoresistive type electronic throttle 3 is achieved.
The present invention is when real work, and engine section waste gas, after electric EGR valve controls, is entered in bypass type cooler by EGR steam outlet pipe, controlled the exhausted air quantity that need cool by bypass valve, and after reaching required cooling effectiveness, waste gas enters throttle body; Engine charge cools with through cooler and waste gas after throttle control enters engine intake manifold after mixing.
