The utility model discloses a protective device for a three-way catalytic converter of an automobile exhaust system. It solves the problem that the expansion liner used to protect the carrier in the existing three-way catalytic converter protection device is prone to aging due to direct contact with the gas discharged from the engine, cannot protect the carrier well, and easily causes the carrier to fall off and break . The structure is: a three-way catalytic converter carrier protection device for automobile exhaust system, which is used to be arranged between the exhaust port of the automobile engine and the muffler, including the carrier protection ring, the carrier arranged in the carrier protection ring, the carrier and the carrier The expansion liner between the protective rings, the front end of the carrier protective ring is provided with a front-end spinning barrel, and the rear end is used to connect with the muffler. It is characterized in that an end cover is provided in the front-end spinning barrel, and the expansion liner The front end of the pad is located in the gap between the end cap spinning barrels.
Description
Technical field
The utility model relates to automobile and sends out the machine vent systems, relates in particular to a kind of automobile exhaust system ternary catalyzing unit carrier protective gear.
Technical background
In order to reduce content of harmful gas in the automobile engine tail gas; so that reach qualified discharge; between the relief opening of motor car engine and baffler, need to be provided with the catalyzer that promotes the harmful gas oxidation; the material that contains catalyzer is sprayed onto on the columniform porous carrier, and carrier is held in place in the carrier guard circle set between baffler and the air vent of automobile engine.In order to protect carrier, between carrier and carrier guard circle, also be provided with columnar inflated insert, so that carrier can stably remain in the carrier guard circle.General ternary catalyzing unit carrier protective gear is made up of carrier guard ring (406 steel wire) and inflated insert (being used for Minnesota Mining and Manufacturing Company) more, is wrapped in carrier and adopts pressure type and comparatively advanced at present binding packaged type to fix carrier all around.Because the front end of inflated insert is directly towards exhaust opening of engine; inflated insert is prone to aging distortion; thereby reduce or lose protective action carrier; using or be subjected to the effect of engine exhaust back pressure and exhaust rotating vortex for a long time; occur that carrier comes off and the local broken phenomenon of carrier through regular meeting, finally cause problems such as exhaust abnormal sound and tail gas exceed standard.
Summary of the invention
For overcoming the above-mentioned defective that existing automobile exhaust system ternary catalyzing unit carrier protective gear is had; the utility model technical issues that need to address are: a kind of novel automobile exhaust system ternary catalyzing unit carrier protective gear is provided; it can avoid inflated insert directly towards engine exhaust port; help the stable of inflated insert performance; thereby can be carrier comparatively permanent protection is provided; improve the working life of carrier, helped guaranteeing the vehicle exhaust qualified discharge.
For solving the problems of the technologies described above; the technical solution of the utility model: a kind of automobile exhaust system ternary catalyzing unit carrier protective gear; be used to be arranged between air vent of automobile engine and the baffler; comprise the carrier guard circle, be located at carrier, the inflated insert between carrier and carrier guard circle in the carrier guard circle; carrier guard circle front end is provided with front end spinning staving; the rear end is used for being connected with baffler; it is characterized in that; in front end spinning staving, be provided with end cap, in the gap of the front end of described inflated insert between end cap spinning staving.End cap generally is to be made by stainless steel material, it is connected in the front end spinning staving by the mode of welding, can cover in the front end of inflated insert, avoid high temperature in the air vent of automobile engine, had the front end place that corrosive gas is directly injected to inflated insert.
As preferably, described spinning staving is tapered, and described end cap also is taper, and the tapering between them is close, and both coaxial arrangement together.Both are taper, are convenient to arrange, make things convenient for the exhaust of engine exhaust port, and gas can fully be contacted with supported catalyst, promote the oxidation of harmful gas.
As preferably, the rear end of described end cap snaps onto the front end of carrier.Both link together in the mode of snapping, have increased connectivity robustness between the two.
As preferably, the rear end of described end cap is provided with along the axially extended ring-type port of carrier, and this port snaps onto on the outer circumferential face of carrier front end.The port that is provided with ring-type had both guaranteed that end cap can cover in inflated insert fully, also can increase the intensity of carrier simultaneously.
As preferably, the contacted length of described port and carrier is about 1cm.
Therefore, the beneficial effects of the utility model:
Owing in front end spinning staving, establish the end cap that can shelter from the inflated insert front end; the high temperature of discharging in the enmgine exhaust, have corrosive air-flow of suppressing and can not contact with inflated insert; but directly impact on the end cap inwall; inflated insert is difficult for therefore aging and follows the string; thereby can more stably protect carrier not to be damaged; supported catalyst also can provide oxidation catalysis effect preferably for the harmful gas in the tail gas, helps the qualified discharge of tail gas.
Description of drawings
Accompanying drawing 1 is the sectional view of the utility model automobile exhaust system three-way catalyst protective gear.
Accompanying drawing 2 is sectional views of end cap.
Embodiment
See accompanying drawing; the utility model automobile three-way catalyst protective gear is used to be arranged on air vent of automobile engine and disappears between the hidden weapon, and structure comprises carrier guard circle 2, be located at carrier 4 in the carrier guard circle 2, inflated insert 3 between carrier guard circle 2 and carrier 4, that made by the elasticity nonmetallic material.The front end of carrier guard circle 2 is provided with the front end spinning staving 1 that is connected as a single entity with it, and this front end spinning staving is used to be connected the relief opening position of motor car engine, and the rear end of carrier guard circle 2 is used for being connected with the hidden weapon that disappears.
Described front end spinning staving 1 is tapered, is provided with end cap 5 in front end spinning staving 1, and end cap 5 is also for taper, and the tapering of it and front end spinning staving 1 is close.End cap 5 is made by stainless steel material, and it generally is to be connected together by mode and the front end spinning staving 1 that welds, and it and front end spinning staving 1 are set together coaxially.
The front end of end cap 5 is towards exhaust opening of engine, and the rear end snaps onto the front end of carrier 4.The rear end of end cap 5 is provided with a port that is connected as a single entity with it 6, and port 6 is circular, and it extends axially along carrier 4, and port 6 is socketed on the outer circumferential face of carrier 4 front ends.End 6 is about about 1cm with carrier 4 contacted length.
Like this, end cap 5 is with after carrier 4 is connected, the front end of described inflated insert 3 is promptly in the gap between end cap 5 and described front end spinning staving 1, and the gas of discharging in the engine exhaust port directly impacts on the inwall of end cap 5, and does not contact with inflated insert 3.
