Intelligent Control of Exhaust Back-pressure Fuel-efficient Structure

Abstract

The present invention relates to a exhaust pipe structure with back-pressure controlling and fuel saving comprising: a barrel, with an inner tube; a back-pressure device, connected to said barrel, with a back-pressure pipe inside, said back-pressure pipe with one or more holes on it; and a rear tube, connected to said barrel, with an opening and silencer plug at appropriate place. When the engine of the car exhausting waste gas generated due to combustion, the flame companied with the waste gas could be resisted by the back-pressure device to avoid engine knock, the back-pressure device also could control and balance the flow rate when exhausting waste gas, so that it makes the engine working at low speed with high torque and speed, by this way, not only makes exhaust smoothly and reduces the burden when engine at high temperature, but also achieves the purpose of fuel saving.

What is claimed: 
     
         1 . A exhaust pipe structure with back-pressure controlling and fuel saving comprising:
 A barrel, with an inner tube;   A back-pressure device, connected to said barrel, with a back-pressure pipe inside, said back-pressure pipe with one or more holes on it; and   A rear tube, connected to said barrel, with an opening and silencer plug at appropriate place;
 with above said design and structure, when the engine of the car exhausting waste gas generated due to combustion, the flame companied with the waste gas could be resisted by the back-pressure device to avoid engine knock, the back-pressure device also could control and balance the flow rate when exhausting waste gas, so that it makes the engine low speed with high torque and high speed with force, by this way, not only makes exhaust smoothly, makes the next intake process can quickly and fully inhale fresh air and reduces the burden when engine at high temperature, but also achieves the purpose of fuel saving. 
   
     
     
         2 . The exhaust pipe structure with back-pressure controlling and fuel saving as in  claim 1 , wherein said barrel could comprise a silencer, the silencer is set to cover over said inner tube. 
     
     
         3 . The exhaust pipe structure with back-pressure controlling and fuel saving as in  claim 2 , wherein said silencer could be made of glass fiber silencer cotton or metal silencer cotton. 
     
     
         4 . The exhaust pipe structure with back-pressure controlling and fuel saving as in  claim 1 , wherein said inner tube could be equipped with a spiral pile to reduce the noise. 
     
     
         5 . The exhaust pipe structure with back-pressure controlling and fuel saving as in  claim 2 , wherein said inner tube could be equipped with a spiral pile to reduce the noise. 
     
     
         6 . The exhaust pipe structure with back-pressure controlling and fuel saving as in  claim 1 , wherein said back-pressure device could be equipped with one or more opening device could be used to adjusting the opening state of the holes of the back-pressure pipe. 
     
     
         7 . The exhaust pipe structure with back-pressure controlling and fuel saving as in  claim 2 , wherein said back-pressure device could be equipped with one or more opening device could be used to adjusting the opening state of the holes of the back-pressure pipe. 
     
     
         8 . The exhaust pipe structure with back-pressure controlling and fuel saving as in  claim 1 , wherein said barrel, back-pressure device, rear tube could be integrated or disassembled. 
     
     
         9 . The exhaust pipe structure with back-pressure controlling and fuel saving as in  claim 2 , wherein said barrel, back-pressure device, rear tube could be integrated or disassembled.
