Abstract
The invention discloses an exhaust purification system with a mounting plate structure. The exhaust purification system comprises an exhaust manifold, a catalytic converter and a connector which are communicated in sequence, wherein the connector comprises a casing head and a connecting pipe which are communicated with each other; the casing head is connected with the catalytic converter; the connecting pipe is also sleeved with an elliptical mounting plate which is provided with four supporting legs, and each supporting leg is provided with a mounting hole. The purification system is reasonable in structure, can achieve a better waste gas purification effect, can be better fixed, and is free of pipeline loosening.
Description
Technical field
The present invention relates to automobile technical field, specifically with the emission control system of mounting plates structure.
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 structural design is unreasonable, and the waste-gas cleaning effect is not fine, and simultaneously, purification plant can not be realized fixing preferably, pipeline easily occurs loosening.
Summary of the invention
The invention provides the emission control system with mounting plates structure, solved that the purification plant structural design was unreasonable in the past, the waste-gas cleaning effect is not fine, and simultaneously, purification plant can not be realized fixing preferably, the loosening problem of pipeline easily occurs.
The present invention is that the technical solution problem is achieved through the following technical solutions: with the emission control system of mounting plates structure, 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 be socketed with mounting plate on the described connecting tube, described mounting plate ovalize, and mounting plate is provided with four legs, and each leg is provided with a mounting hole.By the leg on mounting plate and the mounting plate, purification plant is fixed.
Further, the line of described four projections of leg on mounting plate surrounds a rectangle.
Further, described leg is " V " font, and the angle that this " V " font becomes is 90 ~ 150 degree.
Further, described connecting tube is provided with outside thread, and mounting plate is provided with tapped through hole, and this through hole matches with connecting tube.
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.Nut is used for cooperating with outer bolt, and gas exhaust manifold is fixing better.
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, and simultaneously, increase mounting plate again, whole cleaning system is fixed, so both accomplish compact structure, reasonable, and also avoided gas exhaust piping to occur simultaneously loosening, even the problem of gas leakage.
(2) the present invention is simple in structure, convenient operation and realization, and working life is longer, and then has reduced the cost input, and practicability is also stronger.
