Flexible control device for time-section factor

Abstract

The present invention provides a control device for continuously variable time and cross section which is added the throttle control valve 10, the element 8 of throttle control valve and the relevant drive mechanism 1 in the regular intake and exhaust system of internal combustion engine. The throttle control valve 10 is fixed in the cavity, which is composed of the fluid flow passage 11 in the cylinder head 7, the valve seat 12 and the valve 9. The throttle control valve 10 is cylindrical, and its axis of motion is just the same as that of the valve guide or is parallel with it. Through controlling the relative movement between the valve 9 and the throttle control valve 10 it is flexible to adjust the cross-section area of fluid flow passage, effective valve phase, working time, effective lift and swirl intensity of fluid movement in the course of periodic opening and closing of valve. The present invention can apparently improve the performance of cold start-up of the engine in the low temperature, and can make the engine have the perfect economical and dynamic performance, low noise and low emission. At the same time the direct control of EGR can be easily realized with it.

The throttle control valve  10  is cylindrical, and its axis of motion is just the same as that of the valve guide and valve  9  or is parallel with it. There is a relative up-and-down movement between the throttle control valve  10  and the valve  9 . The drive mechanism of throttle control valve  1  can control the throttle control valve  10  through the element  8  of throttle control valve which is connected with it.  
     
     
         2 . The control device of  claim 1  wherein said comprise: 
 The character of this device is that there is an eccentric hole (h 2 ) near the said valve guide  6  in the cylinder head  7 . The axis of the hole is parallel with that of valve guide  6 , and the element  8  of throttle control valve runs across this hole.  
 
     
     
         3 . The control device of  claim 1  including: 
 The character of this control device lies in the fact that there is an eccentric hole (h 1 ) in the said valve spring seat  3  with which the axis of valve locker  4  is parallel, and the element  8  of throttle control valve runs across this hole.  
 
     
     
         4 . The control device of  claim 1  wherein said comprises: 
 The character of this device is the fact that there are two holes, one is the eccentric hole (h 2 ) which is near the said valve guide  6  in the cylinder head  7  and its axis is parallel with that of valve guide  6 , the other is the eccentric hole (h 1 ) which is in the said valve spring seat  3  and its axis is parallel with that of valve locker  4 . The element  8  of throttle control valve runs across these two holes.  
 
     
     
         5 . Any item on the control devices stated in the above-mentioned  claim 1:   The character of this control device is that it is gap assembling between the external circle of said throttle control valve  10 , the internal wall of fluid flow passage  11 , and the internal hole of valve seat  12 ; and the bottom of this device is matched with the mushroom valve  9 .    
     
     
         6 . Any item on the control devices of the above-mentioned  claim 5  wherein said comprises: 
 The character of this lies in the details that all external circle of said throttle control valve  10  is cylindrical; there is an inward projecting part at the upper portion of the inner circumference and this projecting part is connected with the element  8  of throttle control valve.  
 
     
     
         7 . The control device of  claim 5  including: 
 The character of this device is that partial external circle of said throttle control valve  10  is cylindrical; there is an outward projecting part at the upper portion of the surface of circumference and this projecting part is connected with the element  8  of throttle control valve.  
 
     
     
         8 . The control device of  claim 5  wherein said comprises: 
 The character of this control device lies in the fact that all external circle of said throttle control valve  10  is cylindrical, and the element  8  of throttle control valve is connected with the inner circumference of the throttle control valve  10 .  
 
     
     
         9 . The control system of  claim 6  including: 
 Its character is that the element  8  of throttle control valve is baculiform and the throttle control valve  10  and the element  8  of throttle control valve can be made as a single component, or assembled by two different components.
