Description
Technical field
The present invention relates to automobile technical field, specifically can avoid motor oscillating to affect the bubble-tight purification plant of pipeline.
Background technique
Manifold is a kind of pipeline structure for automotive air intake, vent systems, can be divided into intake manifold and gas exhaust manifold.Intake manifold is between closure and engine air admittance door, after air enters closure, behind the manifold dsah-pot, air flow channel begins difference, and the quantity of corresponding engine cylinder just has four roads such as four cylinder engines, corresponding five roads of five cylinder engines import air respectively in each cylinder.With NA Naturally Aspirated Engine, because intake manifold is positioned at after the closure, so when engine throttle aperture hour, can't be drawn onto the air of capacity in the cylinder, will cause the mainfold vacuum degree high; And when the engine throttle aperture was large, the degree of vacuum in the intake manifold will diminish.Therefore, spraying the fuel feeding engine all can at pressure meter of intake manifold installing, supply with ECU and judge the engine load, and give an amount of oil spout.And gas exhaust manifold links to each other with engine cylinder, the exhaust of each cylinder is put together import exhaust manifold, pipeline structure that band is disagreed.Requirement to it mainly is to reduce exhaust resistance as far as possible, and avoid phase mutual interference between each cylinder.During the exhaust undue concentration, can produce the phase mutual interference between each cylinder, during namely certain cylinder exhaust, just in time meet other cylinder and alter the next waste gas that does not have emptying.Like this, will increase the resistance of exhaust, and then reduce the output power of motor.Solution is, makes the exhaust of each cylinder as far as possible separately, branch of every cylinder, and perhaps branch of two cylinders, and each branch is lengthened as far as possible and moulding-influence each other with the gas that reduces in the different pipes.In order to reduce exhaust resistance, some racing car adopts Stainless Steel Tube to make gas exhaust manifold.
Because the fuel oil in the engine often can not perfect combustion, causes carbon distribution to produce, and piles up, toxic substance is more and more, if directly with so poisonous Bas Discharged, will major polluting atmosphere environment, so vehicle exhaust has a purified treatment step before discharge.But present purification plant structure is not quite reasonable, causes volume relatively large, the problem of manifold gas leakage also may occur simultaneously.Also have, because whole venting gas appliance is connected with motor, the vibration of motor probably causes the loosening of gas exhaust manifold, also can cause gas leakage.
Summary of the invention
The invention provides and to avoid motor oscillating to affect the bubble-tight purification plant of pipeline, having solved in the past, the purification plant structure is not quite reasonable, cause volume relatively large, simultaneously, because whole venting gas appliance is connected with motor, the vibration of motor probably causes the loosening of gas exhaust manifold, causes the problem of gas leakage.
The present invention is that the technical solution problem is achieved through the following technical solutions: can avoid motor oscillating to affect the bubble-tight purification plant of pipeline, comprise the gas exhaust manifold, catalyst converter, the connecting head that are communicated with successively, described connecting head comprises the pullover and connecting tube that is interconnected, described pulloverly be connected with catalyst converter;
Also comprise flange, described flange is provided with a plurality of jacks, and the mouth of pipe correspondence of gas exhaust manifold is inserted in each jack, also is provided with a plurality of tapped holes on the described flange;
Also comprise fixing frame, an end of described fixing frame be fixed on pullover on, the other end of fixing frame is provided with jack hole.Fixing frame is used for motor is fixedly connected with purification plant, prevents from relative displacement occurs between them, causes pipeline to occur loosening.
The waste gas that each cylinder produces enters into catalyst converter by gas exhaust manifold, finishes reaction, dusty gas is changed into nontoxic gas after, enter next link by connecting head; Flange is used for unified fixedly each mouth of pipe of gas exhaust manifold, guarantees tightness; Tapped hole on the flange can be realized the further fixing of flange.
Further, be socketed with fixed plate on the described connecting tube, described fixed plate is provided with at least two fixed holes.Fixed plate can make whole purification plant realize better fixing, and prevents from becoming flexible.
Further, described connecting tube is provided with outside thread, and fixed plate is provided with tapped through hole, and this through hole matches with connecting tube.Connecting tube and fixed plate can be easy for installation and removal after adopting screw thread fixing.
Further, described flange is provided with a plurality of fixed strips, and described fixed strip is provided with mounting hole.
Further, being shaped as of described catalyst converter is cylindrical, connecting tube be shaped as cylindrical shape, the diameter length of catalyst converter is 2 ~ 4 times of diameter length of connecting tube.
Further, described gas exhaust manifold is provided with positioning hole, and this positioning hole place is provided with a nut.By adding bolt, realize the further fixing of gas exhaust manifold with the nut cooperation.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) gas exhaust manifold of the present invention, catalyst converter, connecting head adopt the mode that connects successively and be communicated with to fix, adopt simultaneously flange that each mouth of pipe of gas exhaust manifold is unified fixing, so both accomplish compact structure, rationally, also avoided the mouth of pipe of the gas exhaust manifold problem that leaks air simultaneously.
(2) the present invention is at the pullover fixing frame that is provided with, and realizes being fixedly connected with of purification plant and motor by fixing frame, thereby prevented between purification plant and the motor relative displacement occuring, and avoided pipeline to occur to become flexible, thereby guaranteed the tightness of pipeline.
