Technical field
The present invention relates to a kind of automobile exhaust system outlet pipe technology field.
Background technique
Society automobile is the universal whole world, becomes the indispensable traffic tool in people's life.Outlet pipe is the requisite part of automobile, and it is installed between enmgine exhaust and silencing apparatus, thus plays vibration and noise reducing and extend exhausting silencer system working life.Having residual gas during current outlet pipe exhaust work gets lodged in pipe, produces and when meeting with residual gas, can produce the resistance of exhaust when new gas, reduces the delivery efficiency of motor and the working life of gas exhaust manifold.
Content of the present invention
Problem to be solved by this invention is to provide the good gas exhaust manifold of a kind of exhaust performance, solving residual gas gets lodged in pipe, produce when new gas and when meeting with residual gas, produce the resistance of exhaust, reducing the delivery efficiency of motor and the problem in the working life of gas exhaust manifold.
For overcoming the above problems scheme of the present invention:
The gas exhaust manifold that a kind of exhaust performance is good, comprise the first bend pipe, second bend pipe, excessive pipe, fan-shaped mouth, circular port, the first described bend pipe and the second bend pipe to be connected formula structure by the excessive pipe that a sectional shape is arc, first described bend pipe one end is fan-shaped mouth with excessively managing the other end that is connected, and second described bend pipe one end is circular port with excessively managing the other end that is connected.
The gas exhaust manifold that above-mentioned a kind of exhaust performance is good, wherein, the radian of described excessive pipe is α, α is 60 °-80 °.
The gas exhaust manifold that above-mentioned a kind of exhaust performance is good, wherein, the radian of described fan-shaped mouth is β, β is 90 °.
The gas exhaust manifold that above-mentioned a kind of exhaust performance is good, wherein, the first described bend pipe and the radian excessively between pipe are γ, γ is 90 °-110 °.
The gas exhaust manifold that above-mentioned a kind of exhaust performance is good, wherein, the second described bend pipe and the radian excessively between pipe are δ, δ is 100 °-120 °.
The gas exhaust manifold that above-mentioned a kind of exhaust performance is good, wherein, the first described bend pipe, the second bend pipe and excessive pipe adopt stainless steel material to make.
The beneficial effect of this programme:
The gas exhaust manifold that a kind of exhaust performance provided by the invention is good, comprise the first bend pipe, second bend pipe, excessively manages, fan-shaped mouth, circular port, first bend pipe one end is fan-shaped mouth with excessively managing the other end that is connected, and second bend pipe one end is circular port with excessively managing the other end that is connected, and is convenient to install, structure is simple, and finished product is low; First bend pipe and the second bend pipe to be connected formula structure by the excessive pipe that a sectional shape is arc, the radian measure alpha of excessive pipe is 60 °-80 °, first bend pipe and the radian measure gamma excessively between pipe are 90 °-110 °, second bend pipe and the radian δ excessively between pipe are 100 °-120 °, within the scope of this, exhaust effect is best, be conducive to the delivery efficiency improving motor, increase the service life.
