Abstract
The utility model discloses a compact exhaust purification system convenient to fix. The compact exhaust purification system comprises an exhaust manifold, a catalytic converter and a connector which are sequentially communicated with one another, wherein the connector comprises a sleeve head and a connecting pipe which are communicated with each other, the sleeve head is connected with the catalytic converter, an oval mounting plate is also sleeved on the connecting pipe and provided with four supporting feet, and a mounting hole is formed in each supporting foot. By adopting the structure, the purification device can be reasonable in structure and can achieve a good exhaust gas purification effect, meanwhile, a purification device can be well fixed, and a pipeline can be prevented form being loosened.
Description
Technical field
The utility model relates to automobile technical field, specifically facilitates fixing compact type emission control system.
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, after the manifold dsah-pot, air flow channel starts difference, and the quantity of corresponding engine cylinder, as four cylinder engine Jiu You tetra-roads, corresponding five roads of five cylinder engines, import air respectively in each cylinder.With NA Naturally Aspirated Engine, due to after intake manifold is positioned at closure, so, when engine throttle aperture hour, in cylinder, can't be drawn onto enough air, will cause the mainfold vacuum degree high; And, when the engine throttle aperture is large, the degree of vacuum in intake manifold will diminish.Therefore, spray the fuel feeding engine and all can on intake manifold, install a pressure meter, supply with ECU and judge the engine load, and give appropriate oil spout.And gas exhaust manifold is connected with engine cylinder, the exhaust of each cylinder is put together and imports exhaust manifold, pipeline structure that band is disagreed.To it requirement mainly, reduce exhaust resistance as far as possible, and avoid phase mutual interference between each cylinder.During the exhaust undue concentration, between each cylinder, can produce the phase mutual interference, during namely certain cylinder exhaust, just in time meet other cylinder and alter the next waste gas that there is no 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, or branch of two cylinders, and each branch is lengthened as far as possible and moulding-with the gas reduced in different pipes, influence each other.In order to reduce exhaust resistance, some racing car adopts Stainless Steel Tube to manufacture gas exhaust manifold.
Because the fuel oil in engine often can not perfect combustion, cause carbon distribution to produce, pile up, toxic substance is more and more, if directly by so poisonous Bas Discharged, will major polluting atmosphere environment, so vehicle exhaust has a purified treatment step before discharge.But current purification plant structural design is unreasonable, the waste-gas cleaning effect is not fine, and simultaneously, purification plant can not be realized fixing preferably, easily occurs that pipeline is loosening.
The model utility content
The utility model provides convenience fixing compact type emission control system, has solved that the purification plant structural design was unreasonable in the past, and the waste-gas cleaning effect is not fine, and simultaneously, purification plant can not be realized fixing preferably, the problem that pipeline is loosening easily occurs.
The utility model is that the technical solution problem is achieved through the following technical solutions: facilitate fixing compact type emission control system, comprise the gas exhaust manifold, catalyst converter, the connecting head that are communicated with successively, described connecting head comprises the pullover and connecting tube be interconnected, described pulloverly be connected with catalyst converter, also be socketed with mounting plate on 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 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, 2 ~ 4 times of the diameter length that the diameter length of catalyst converter is connecting tube.
Further, described gas exhaust manifold is provided with positioning hole, and this positioning hole place is provided with a nut.Nut is for coordinating with outer bolt, and gas exhaust manifold is fixing better.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) gas exhaust manifold of the present utility model, catalyst converter, connecting head adopt the mode that connects successively and be communicated with to fix, simultaneously, increase again mounting plate, whole cleaning system is fixed, so both accomplished compact structure, reasonable, also avoided gas exhaust piping to occur loosening, even the problem of gas leakage simultaneously.
(2) the utility model 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.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
