Abstract
The utility model relates to an external purification muffler for Beijing jeep serial vehicles, which comprises a flange disk 1, a housing body 2, a catalytic conversion purifier 3 and a muffler device. The front half part of the housing body 2 is provided with the catalytic conversion purifier 3 and the rear half part is provided with the muffler device, and the rear half part of the housing body 2 is provided with three partition boards 5 which can be divided into a front cavity, a middle cavity and a back cavity. A hollow throat 6 is arranged at the middle of two partition boards 5, namely the inner part of the middle cavity. A guide tube 4 is arranged between the three partition boards 5, namely the inner parts of the front cavity and the middle cavity. An exhaust tube 7 passes through the three partition boards 5. Holes are arranged on the guide tube 4 and the hollow throat 6. The utility model combines the functions of tail gas purification and noise elimination as integration, and meanwhile, the utility model reaches the standards and has no change of any part of an original automobile.
Description
The utility model relates to the external purification silencing apparatus of a kind of Beijing jeep series automobiles, is suitable for the tail gas clean-up and the noise elimination of Beijing jeep series automobiles.
The gasoline engine car that present China generally adopts is the carburetor type oil supply system, and institute's discharge tail gas has substantially exceeded country and local emission standard.Therefore solve the exceed standard main method of problem of exhaust emissions, install the catalyzed conversion purifier exactly additional.But need remove automotive muffler because the catalyzed conversion purifier is installed on the jeep series automobiles of Beijing, take the automotive muffler position, the problem of having brought displacement noise to exceed standard so again.
For making engine exhaust emission up to standard, must remove this car silencing apparatus, account for the outer catalyzed conversion purifier of its position fitting machine, but the problem of engine exhaust noise can't solve, and this vehicle chassis structure, purifier and silencing apparatus can't be installed simultaneously, 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, a kind of internal structure that changes original baffler is provided, employing one integrates the external purification silencing apparatus of Beijing jeep series automobiles that purifies the two kinds of functions of eliminating the noise, make it reach good purification and noise elimination effect, satisfy the emission standard requirement.
The purpose of this utility model can realize by following measure:
The external purification silencing apparatus of a kind of Beijing jeep series automobiles, it comprises flange plate (1), housing (2), catalyzed conversion purifier (3) and silencer, it is characterized in that housing (2) front half part is provided with catalyzed conversion purifier (3), housing (2) latter half part is provided with silencer; Silencer is by conduit (4), dividing plate (5), trunnion (6) and outlet pipe (7) are formed, housing (2) latter half part is provided with and can be divided into ante-chamber, three dividing plates (5) of lumen and back cavity, trunnion (6) is arranged on the centre of two dividing plates (5), be in the lumen, conduit (4) is arranged between three dividing plates (5), be in ante-chamber and the lumen, one end of conduit (4) leads to the purifier exocoel, the other end leads to back cavity, and outlet pipe (7) passes outside logical housing (2) bonnet of three dividing plate 5, one ends, the other end leads to catalyzed conversion purifier exocoel, and conduit (4) and trunnion (6) are provided with the hole.Package unit front end flange (1) is connected with the engine exhaust pipe flange.
Advantage of the present utility model:
1, this external purification silencing apparatus collection tail gas clean-up, the two kinds of functions of eliminating the noise can make purifying vehicle exhaust in one, eliminate the noise, and reach exhaust emission standard and noise standard requirement simultaneously.
2, this purifying muffler takes up room for a short time, and the former car silencing apparatus position of only occupying rational in infrastructure can be played two kinds of effects simultaneously.
3, this external purification silencing apparatus profile and connecting means connect former car silencing apparatus external dimension design fully, and be easy for installation, need not change any parts of former car.
Description of drawings is as follows: accompanying drawing 1 is a structural representation of the present utility model.
Below by embodiment, be described in further detail in conjunction with the accompanying drawings:
The utility model is by flange plate 1, shell (2), catalyzed conversion purifier (3) and silencer are formed, catalyzed conversion purifier (3) is installed in the front half part of housing (2), silencer is installed in the latter half part of housing (2), silencer is by conduit (4), dividing plate (5), trunnion (6) and outlet pipe (7) are formed, the latter half part of housing (2) is provided with three dividing plates 5, be divided into ante-chamber lumen and back cavity, trunnion 6 is arranged on the centre of two dividing plates 5, promptly in the lumen, conduit 4 is arranged between three dividing plates 5, be in ante-chamber and the lumen, an end of conduit leads to the purifier exocoel, and the other end leads to back cavity; Outlet pipe 7 passes three dividing plate 5, one ends by outside the housing bonnet, and the other end leads to catalyzed conversion purifier exocoel, and conduit 4 and trunnion 6 are provided with the hole.Motor car engine is discharged gas, enters the noise elimination ante-chamber by catalyzed conversion purifier (3), enters noise elimination lumen and back cavity by trunnion (6) again, enters the exocoel of purifier 3 again by conduit (4), finally discharges by outlet pipe (7).A whole set of purifying muffler is installed on the former silencing apparatus of jeep series automobiles position, Beijing, and after piloting engine, waste gas can reach by this purifier and purify the optimum efficiency of eliminating the noise.
