An exhaust pipe for improving the efficiency of the exhaust system

Abstract

The invention discloses an exhaust pipe for improving the efficiency of an exhaust system, and relates to the field of exhaust pipes, including a main exhaust pipe, the end of which is connected with a first auxiliary exhaust pipe and a second exhaust pipe in the form of bifurcations. Exhaust auxiliary pipe, the inner wall of the second exhaust auxiliary pipe is provided with a low-pressure suction area that drains the gas at the outlet of the main exhaust pipe to the second air outlet. When the gas discharged from the main exhaust pipe is transported to the first row When the gas auxiliary pipe and the second exhaust auxiliary pipe are in place, a part of the gas is discharged into the first exhaust auxiliary pipe, and the other part of the gas is discharged into the second exhaust auxiliary pipe. The inner wall at the lower end of the second exhaust auxiliary pipe is provided with The low-pressure suction area can attract the gas at the outlet of the exhaust main pipe into the second exhaust auxiliary pipe, thereby avoiding the phenomenon that a large amount of gas enters the first exhaust auxiliary pipe, and the low-pressure suction area can reduce the weakening degree of the gas when it is transported role.

Description

technical field [0001] The invention relates to the field of exhaust pipes, in particular to an exhaust pipe for improving the efficiency of an exhaust system. Background technique [0002] The exhaust pipe is mainly used to discharge gas. The turning positions of the exhaust pipes in the prior art are all arranged in the form of elbows. Because the structure of the elbows produces a diffused structure in some areas, flow separation occurs. After the flow separation, the flow loss will increase and the flow rate will be reduced, thereby It affects the efficiency of exhaust, especially when there are two bifurcated pipes at the end of a main exhaust pipe, due to the natural exhaust principle of the gas in the high pressure area flowing to the low pressure area, the intake end of the main exhaust port here is the high pressure area, The end of the air outlet is the low pressure area. The position where the air outlet is closer to the main exhaust pipe emits more gas, and the ...

Problems solved by technology

The turning position of the exhaust pipe in the prior art is arranged in the form of an elbow. Because the structure of the elbow produces a diffused structure in some areas, flow separation occurs. After flow separation, the flow loss will increase and the flow velocity will be reduced. Affect the exhaust efficiency, especially when there are two bifurcated pipes at the end of a main exhaust pipe, due to the natural exhaust principle that the gas in the high pressure area flows to the low pressure area, the intake end of the main exhaust port here is the high pressure area, The end of the gas outlet is the low-pressure area. The gas outlet near the main exhaust pipe emits more gas, and the gas outlet farther from the main exhaust pipe emits less gas, resulting in uneven exhaust.
