Energy-saving exhaust pipe featuring changeable pressure

Abstract

The invention discloses an energy-saving exhaust pipe featuring changeable pressure, comprising a sleeve; the sleeve is provided with an air inlet and an air outlet respectively; the rear end of the sleeve and the margin of the air outlet are respectively provided with a cover plate and a baffle plate; the air inlet, the air outlet, the cover plate and the baffle plate form a closed chamber in the sleeve; a mounting pad is fixed in the closed chamber positioned at the back of the sleeve; a piston rod penetrates through the cover plate, the mounting pad and the baffle plate; the front end of the piston rod is provided with a piston sheet; the part of the outer wall of the piston sheet, which is in the closed chamber, is sheathed with a supporting plate corresponding to the size of the closed chamber; the supporting plate is provided with a spilehole; the outer wall of the piston rod is sheathed with a spring between the supporting plate and the mounting pad; an adjusting bolt is arranged at the rear end of the piston rod; a buffer spring on the outer wall of the piston rod is arranged at the front end of the adjusting bolt. The energy-saving exhaust pipe has the advantages of simple structure, low cost, unnecessary control by control systems, long service, convenient installation and environmental protection and can achieve the aims of improving drive, hoisting power and reducing exhaust and mechanical noises.

Description

technical field [0001] The invention relates to a pressure-variable energy-saving exhaust pipe with exhaust gas recirculation function installed on the engine exhaust pipe. Background technique [0002] At present, the exhaust pressure produced by the existing engine when it is working varies with the engine speed and operating conditions. Since the exhaust diameter of the traditional automobile exhaust pipe cannot be changed, it causes the engine to work under low load. The air pressure of the exhaust pipe is not enough, so that the mixed gas cannot absorb the residual heat left in the exhaust gas of the cylinder after entering the cylinder, resulting in insufficient volatilization and vaporization of the fuel, so that the mixed gas cannot be fully burned, and the mixed gas is not fully burned It will also cause carbon deposits in the engine and high operating temperature, which will affect the service life of the engine and other issues. Conversely, when the engine is wor...

Problems solved by technology

[0002] At present, the exhaust pressure produced by the existing engine when it is working varies with the engine speed and operating conditions. Since the exhaust diameter of the traditional automobile exhaust pipe cannot be changed, it causes the engine to work under low load. The air pressure of the exhaust pipe is not enough, so that the mixed gas cannot absorb the residual heat left in the exhaust gas of the cylinder after entering the cylinder, resulting in insufficient volatilization and vaporization of the fuel, so that the mixed gas cannot be fully burned, and the mixed gas is not fully burned It will also cause carbon deposits in the engine and high operating temperature, which will affect the service life of the engine and other issues.

Conversely, when the engine is working at a high load, the air pressure in the exhaust pipe is too high, which will cause the engine to exhaust poorly, the intake air volume is insufficient, the mixture is too thick, the resistance to movement increases, the vibration of the engine is large, the oil film is uneven, and the engine Increased working temperature, carbon deposition, disadvantages
