Abstract
The utility model relates to an external purifying and silencing device for Beijing Jeep series automobiles, which comprises a shell body 3, ceramic carrier catalyst 6 and a silencing device. The front half part of the shell body 3 is filled with the ceramic carrier catalyst 6, when the exhaust of an engine is discharged, the purifying effect is achieved by the catalyst, the silencing device is arranged on the back half part of the shell body 3, a partition board 8 is arranged between a front and a back cavities of the back half part of the shell body 3, and the partition board 8 is provided with three holes. A middle hole is provided with a tapered sleeve 7, and both side holes are provided with a throat pipe 9 and a main exhaust pipe 10. The exhaust of an automobile directly enters a silencing back cavity through the tapered sleeve 7, enters a silencing front cavity through the throat pipe 9, and is discharged through the main exhaust pipe 10.
Description
The utility model is a kind of external purification silencing apparatus that is used for Beijing jeep series automobiles, is applicable to the tail gas clean-up and the noise elimination of Beijing jeep series automobiles.
At present, the gasoline engine car that China generally adopts is the carburetor type oil supply system, and institute's discharge tail gas has substantially exceeded country and provincial standard, and therefore, solving exceed standard one of the method for problem of exhaust emissions is exactly that purifier outside engine is installed.But need remove former car silencing apparatus because purifier outside engine is installed, take former car silencing apparatus mounting point, the problem of having brought the exhaust emissions noise to exceed standard so again.
For making engine exhaust emission up to standard, must remove the former silencing apparatus of this car, account for the outer exhaust purifier of its position fitting machine, but the problem of engine exhaust noise can't solve, and this vehicle chassis structure can't have been installed purifier and silencing apparatus simultaneously, and this contradiction is particularly outstanding on present Beijing jeep car.
The purpose of this utility model is exactly the deficiency that exists on the above-mentioned prior art, change the internal structure of motor silencer, adopt a kind of external purification silencing apparatus that is used for Beijing jeep series automobiles that purifies the two kinds of functions of eliminating the noise that integrates, make it reach good purification and noise elimination effect.
The purpose of this utility model can realize by following measure:
1. external purification silencing apparatus that is used for Beijing jeep series automobiles, it comprises flange plate (1), takes over (2), housing (3), ceramic-substrate catalyst (6) and silencer: housing (3) front half part is equipped with ceramic-substrate catalyst (6), the outer surface of ceramic-substrate catalyst (6) is equipped with steel mesh (4), is provided with liner (5) between the steel mesh (4); Silencer is arranged on the latter half part of housing (3), silencer is made up of taper sheath (7), dividing plate (8), trunnion (9) and main exhaust (10), taper sheath (7) is arranged in the ante-chamber of latter half part of housing (3), dividing plate (8) is arranged on the middle part, chamber, front and back of the latter half part of housing (3), three holes are arranged on the dividing plate (8), middle hole connects taper sheath (7), the hole of both sides connects trunnion (9) and main exhaust (10) respectively, and the front end of housing (3) is connected with flange plate (1) by taking over (2).The described external purification silencing apparatus that is used for Beijing jeep series automobiles: trunnion (9) be contained in the housing (3), main exhaust (a 10) part is contained in the housing (3), a part is stretched out outside the housing (3).
Advantage of the present utility model:
1. this external purification silencing apparatus integrates tail gas clean-up, two kinds of functions of noise elimination, can make this tail gas purification, noise elimination reach exhaust emission standard and noise standard requirement simultaneously.
3. this purifying muffler takes up room for a short time, rational in infrastructure, takies former car silencing apparatus position, can play two kinds of effects.
3. former car silencing apparatus size design is pressed in the connection of this external purification silencing apparatus profile fully, and is easy for installation, need not change any parts of former car.
Description of drawings is as follows: Fig. 1 is a structural drawing of the present utility model.
Below by embodiment, be described in further detail in conjunction with the accompanying drawings:
The utility model is organized by housing (3), ceramic-substrate catalyst (6) and silencer, and the front half part of housing (3) is installed ceramic-substrate catalyst (6), and silencer is installed in the latter half part of housing (3).Silencer is made up of taper sheath (7), dividing plate (8), trunnion (9), outlet pipe (10).Motor car engine is discharged gas by catalyzer (6), enters the noise elimination back cavity by taper sheath (7) again, enters the noise elimination ante-chamber by trunnion (9), discharges by outlet pipe (10) again.A whole set of purifying muffler is installed on Beijing jeep series automobiles, after piloting engine in former silencing apparatus position, and the optimum efficiency that waste gas can reach purification, eliminate the noise by this purifying muffler.
Claims (2)
1. external purification silencing apparatus that is used for Beijing jeep series automobiles, it comprises flange plate (1), takes over (2), housing (3), ceramic-substrate catalyst (6) and silencer, it is characterized in that: housing (3) front half part is equipped with ceramic-substrate catalyst (6), the outer surface of ceramic-substrate catalyst (6) is equipped with steel mesh (4), is provided with liner (5) between the steel mesh (4); Silencer is arranged on the latter half part of housing (3), silencer is made up of taper sheath (7), dividing plate (8), trunnion (9) and main exhaust (10), taper sheath (7) is arranged in the ante-chamber of latter half part of housing (3), dividing plate (8) is arranged on the middle part, chamber, front and back of the latter half part of housing (3), three holes are arranged on the dividing plate (8), middle hole connects taper sheath (7), the hole of both sides connects trunnion (9) and main exhaust (10) respectively, and the front end of housing (3) is connected with flange plate (1) by taking over (2).
