The specific work process of the present invention is as follows：
When automobile engine is in idling or little throttle slow-speed of revolution operating mode, throttle signal switch 3 is not closed, while simple
The voltage that easily generator 1 is produced is low, and the switch of single-contact relay 2 is not also closed, and the coil of four contact relays 4 is without electricity
Stream passes through, and this controlling organization does not work, and the sectional area of motor intake manifold is remained on the position of initial setting up.Start
The air door of each cylinder inlet manifold of machine is in half-open half closed state, i.e.,：The air door of left-hand branch inlet manifold 16 is opened, and right side point
The air door for propping up inlet manifold 17 is closed.Such as Fig. 1 and Fig. 5.
When the rotating speed that engine reaches more than medium throttle (setting door oil signal value) and engine reaches per minute 2800
When turning (setting speed value) above operating mode, throttle signal switch 3 is closed, and the voltage for adding the generation of simple generator 1 is raised, single-tap
The normally opened contact switch of point relay 2 is also closed, and the coil of four contact relays 4 has electric current to pass through, the work of this controlling organization.Such as
Fig. 2.
Dc motor 7 is driven forward screw rod 8, nut 9, nut pin 11, connecting rod 10, connection lever pin 12, interior activity
Sleeve 13.The air door of left-hand branch inlet manifold 16 and the air door of right-hand branch inlet manifold 17 are made when interior quill 13 is rotated
During all in full opening of position, upper left upper position-arresting normally-closed contact switchs 5 power-off, and dc motor 7 stops operating, enters
The air door of gas manifold 15 rests on the state of standard-sized sheet.Such as Fig. 3 and Fig. 6.
When engine is less than 2800 turns per minute less than medium throttle (setting throttle signal value) or the rotating speed of engine
During (setting speed value) following operating mode, throttle signal switchs 3 power-off or the normally opened contact switch power-off of single-contact relay 2,
The coil of four contact relays 4 does not have electric current to pass through, the return of four contact relay 4.At this moment, dc motor 7 obtains reverse electricity
Stream, dc motor 7 is driven reverse screw rod 8, nut 9, nut pin 11, connecting rod 10, connection lever pin 12, interior quill
13.Such as Fig. 4.
When the reversion of interior quill 13 returns to the position of initial setting up, bottom-right lower position-arresting normally-closed contact switch 6 breaks
Electricity, dc motor 7 stops operating, and this controlling organization quits work, and this controlling organization is returned on the position of initial setting up.Such as
Fig. 1 and Fig. 5.
Because the working procedure of this controlling organization is gone round and begun again, the sectional area of motor intake manifold is also with going round and beginning again
Change, so as to realize air intake manifold of automotive engine sectional area changeable.The inlet air conditions of engine are effectively improved, are utilized
The inflation effect that air-flow is produced, improves the intake efficiency of automobile engine slow-speed of revolution operating mode, while being conducive in cylinder
Produce whirl air-flow, make fuel-oil atmozation more fully, burning more fully, so as to reach the low speed torque for improving automobile engine, drop
Low oil consumption and the good result of reduction discharge.
