Abstract
The utility model relates to a motor car noise eliminator, comprising a silencer body 1, an exhaust guide tube 2, an air inlet connector 3, a decompression chamber 4 and an exhaust barrel 5. The utility model is characterized in that the decompression chamber 4 is provided between the air inlet connector 3 and the exhaust guide tube 2; the decompression chamber 4 is a cavity chamber which is larger than the bore diameters of the air inlet connector 3 and the exhaust guide tube 2. The utility model has simple structure and convenient installation, can smoothly delivery the horsepower when the engine is in the initial outbreak and acceleration, has better sound-deadening effect, simultaneously decreases the damage on the engine and the silencer brought by the boosted air pressure in the initial outbreak and acceleration of the engine, and extends the service lives of the engine and the silencer.
Description
One, technical field
The utility model relates to a kind of silencing apparatus, is particularly useful for noise eliminator of motorcycle carries out the usefulness of step-down to the high pressure exhaust gas of motor discharge silencing apparatus.
Two, background technique
Existing silencing apparatus is that what baffle plate is installed in its exhaust pipe, or set up several empty chambers, and being connected on the exhaust opening of engine by an elongated conduit, the high pressure exhaust gas that motor is discharged, smoke etc. slow down step by step, be discharged into then in the atmosphere, reach the purpose of noise elimination.But owing in the exhaust pipe what baffle plate is installed, and the connection exhaust pipe is one section elongated pipe, the recoil resistance that when waste gas, smoke to high pressure slow down, is produced, output power to motor has produced great negative effect, obviously be embodied in startup and speed change, the shift process by testing, directly have influence on power steadily, to motor, the influence in silencing apparatus life-span, and it is not really desirable that motor is discharged the effect that the pressure relieving of high pressure exhaust gas, smoke promptly eliminates the noise.
Three, summary of the invention
The purpose of this utility model provides a kind of silencing apparatus, solves motor in initial burst, steady output power when quickening, and the surge air pressure when reducing because of motor initial burst, acceleration simultaneously brings the problem of destruction to motor and silencing apparatus.
The utility model comprises muffler body exhaust pipe, exhaust manifolds, air inlet connecting head, it is characterized in that: be provided with decompression chamber between air inlet connecting head and the exhaust manifolds, this decompression chamber be one than air inlet connecting head and the big chamber of exhaust manifolds internal diameter.
The high pressure exhaust gas that decompression chamber described in the utility model is discharged motor, smoke etc. at first carry out pressure and discharge, thereby reduced high pressure exhaust gas, smoke pressure negative effect power to motor, low pressure exhaust gas, smoke after pressure discharges are again decayed step by step through the obstruct of what plate washer in the exhaust pipe, are discharged in the atmosphere then.
The utlity model has following advantage: motor is steady output power in initial burst, when quickening, it is effective to eliminate the noise, reduce the motor initial burst simultaneously, surge air pressure has prolonged the working life of motor and silencing apparatus to the destruction that motor and silencing apparatus bring when quickening.Simple in structure, easy for installation.
Four, description of drawings
Fig. 1 is the utility model structural representation, also is first embodiment of the present utility model.
Fig. 2 is the utility model structural representation, also is second embodiment of the present utility model.
Fig. 3 is the utility model structural representation, also is the 3rd embodiment of the present utility model.
Five, embodiment
See also Fig. 1 to Fig. 3:
The utility model by muffler body 1, and exhaust pipe 2 air inlet connecting heads, 3, decompression chamber 4 and exhaust pipe 5 form, wherein, silencing apparatus 1 one ends connect exhaust pipe 5, the other end connects exhaust manifolds 2, it is characterized in that: be provided with decompression chamber 4 between air inlet connecting head 3 and the exhaust manifolds 2, this decompression chamber 4 be one than air inlet connecting head 3 and the big chamber of exhaust manifolds 2 internal diameters.
The connecting head that decompression chamber 4 described in the utility model and air inlet connecting head 3 and exhaust manifolds are 2 can be welding, or long connect or be threaded.
Fig. 1 as can be seen, decompression chamber (4) is rugby shape.
Fig. 2 as can be seen, decompression chamber (4) is cylindrical.
Fig. 3 as can be seen, decompression chamber (4) is spherical in shape.
Working principle of the present utility model is: the high pressure exhaust gas that engine emission goes out, smoke etc. are through short air inlet connecting head 3, enter decompression chamber 4 large spaces rapidly and carry out pressure release immediately, thereby reduced the waste gas, smoke of high pressure negative effect power to motor and silencing apparatus 1, low pressure exhaust gas, smoke after step-down discharges are again decayed step by step through the obstruct of several plate washers in the exhaust pipe, are discharged in the atmosphere then.Like this, motor is steady output power in initial burst, when quickening, and the noise elimination better effects if reduces the motor initial burst, the air pressure that increases sharply when quickening is to the destruction that motor and silencing apparatus bring, and prolonged the working life of motor and silencing apparatus simultaneously.
