Description
Technical field
The present invention relates to a kind of engine exhaust pipe, especially a kind of four cylinder engine gas exhaust manifold.
Background technique
The design on waste pipe road has directly had influence on the power performance of motor itself.The exhaust back pressure of motor is the emphasis of a gas exhaust piping design.Exhaust back pressure can improve low speed torque, but can reduce high-speed power simultaneously, how to allow gas exhaust piping adapt to wide in range rotating speed interval, becomes the still unsolved problem of those skilled in the art.Along with the enhancing of environmental consciousness, present motor car engine is based on four cylinder engine, and claimant take four cylinder engine as research object specially, improves the gas exhaust piping of four cylinder engine.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of four cylinder engine gas exhaust manifold, the deficiencies in the prior art can be improved, the adaptability achieving exhaust back pressure in different rotating speeds interval regulates, and makes gas exhaust piping meet low speed simultaneously and improves moment of torsion and propose high-power requirement at a high speed.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of four cylinder engine gas exhaust manifold, comprise four exhaust branch pipes, exhaust branch pipe converges to exhaust supervisor, a flow controller is provided with in each exhaust branch pipe, flow controller comprises the rounded tabs of several annular array, rounded tabs overlaps successively, and be provided with rubber weather strip and linking springs between two adjacent rounded tabs, the edge, windward side of rounded tabs is provided with inclined-plane.
As preferably, described exhaust branch pipe and exhaust are provided with reclinate bend pipe between being responsible for, and the radian of bend pipe is π/8 ~ π/5.
As preferably, described exhaust supervisor is provided with ternary catalyzing unit, and the Upstream section of ternary catalyzing unit is provided with elliposoidal air-inlet cavity, and the tract of ternary catalyzing unit is provided with taper outlet chamber.
As preferably, in described taper outlet chamber, be vertically provided with several guide plates.
As preferably, described taper outlet chamber downstream is connected with damping chamber, and the internal diameter in damping chamber is 4 ~ 6 times of taper outlet chamber outlet port, and damping is provided with oven wire mesh blanket inside chamber.
As preferably, the end of described exhaust supervisor is provided with two independently tailpipes, is connected with by-pass pipe between exhaust supervisor and tailpipe.
As preferably, the end of described tailpipe is provided with reducing.
Adopt the beneficial effect that brings of technique scheme to be: the present invention is by design flow controller, and rounded tabs, under the promotion of exhaust airstream, produces relative movement, the opening of flow controller is changed thus realizes the effect of adjustment exhaust back pressure.When engine speed raises, exhaust flow rate increases, and the opening of flow controller is increased, improves exhaust sectional area, reduce exhaust back pressure.It is contrary when engine speed declines.Bend pipe can reduce the air-flow velocity entering exhaust supervisor, can reduce the flow that exhaust branch pipe is collaborated mutually simultaneously.The elliposoidal air-inlet cavity that ternary catalyzing unit Upstream section is arranged can reduce gas flow rate, and makes air-flow produce turbulent flow, can improve the purifying effect of ternary catalyzing unit.The taper outlet chamber with guide plate that ternary catalyzing unit tract is arranged can be that the air-flow being in turbulent condition improves flowing conformity again, improves exhaust efficiency, reduces noise.The wind that damping chamber can reduce exhaust is made an uproar, and oven wire mesh blanket effectively can suppress the resonance of whole vent systems simultaneously.Two independently tailpipe enough tail end venting sectional areas can be provided, by-pass pipe can flow to the rectification of angle to the air-flow in tailpipe, reduce exhaust and the shock of tailpipe sidewall.Reducing can improve the exhaust velocity of end, plays the efficiency improving moisture and discharge, and reduces vent systems causes corrosion speed owing to accumulating condensed water.
