Abstract
The utility model relates to a multi-functional silencer. The casing structure of the appearance is a bidirectional conic pipe and a stimulating blowout hollow throat. The inside is designed with a turbulator, a power absorber and a two stage ported sub. The utility model still more effectively reduces the exhaust noise, which can enhance the engine power, can reduce the generation of the carbon monoxide and the soot in the combustion process, can decrease the pollution of the end gas and can do the action of eliminating the flame and the spark of the waste gas to achieve the purpose of safety. The utility model can be applied for exhaust systems of various combustion engines such as automobiles, etc.
Description
The utility model belongs to mechanical silencer.Specifically, be the mechanical silencing apparatus that belongs to the internal combustion engine exhaust gas system.
Before the utility model is made, the mechanical silencing apparatus of the internal combustion engine exhaust gas system that always uses in the past, the shell construction of its external form is simple cylindrical tube, and its indoor design has a direct-exhausting type ported sub and three dividing plates, and exhaust flow is directly discharged by ported sub.In use there are a lot of shortcomings in the silencing apparatus of this kind structure: its noise elimination effect is relatively poor, can not improve engine power, carbon monoxide and soot generate in a large number in the combustion process, cause the tail gas public hazards, and flame in the waste gas and Mars can not be eliminated, and is very dangerous in the use.
The utility model improves at above-mentioned shortcoming exactly, thereby has finished a kind of multifunction silencer of new structure.
The utility model is achieved in that
Shown in Figure of description, the shell construction of its external form is two-way conical tube (in the accompanying drawing 1) and draws spray trunnion (in the accompanying drawing 7) and form.Indoor design has turbulator (in the accompanying drawing 2), energy absorber (in the accompanying drawing 4,5) and secondary ported sub (in the accompanying drawing 3,6).
The present invention in the silencing apparatus indoor design turbulator and energy absorber, this technology mainly is to play to change the waste vapour flow path direction and absorb the waste vapour Burning in Effect of Sound Energy, makes it more effectively reduce exhaust noise.The secondary ported sub has also been designed in silencing apparatus inside, and this technology can also play the effect of eliminating flame and Mars in the waste gas except that playing sound deadening, reach the purpose of safety.The afterbody design has speed of a motor vehicle air-flow to draw the spray trunnion, and it can make and form tenuity in the exhaust process in silencing apparatus, promptly produces the suction force of waste gas in the countercylinder.This just helps to improve the flammable amount of charging into of closing vapour, has also reduced the consumption of motor power in exhaust stroke, so can improve the power of motor.Because the existence of suction force makes scavenging more abundant, that is burning is more abundant, thus reduced the generation of carbon monoxide and soot in the combustion process, thereby reduced the tail gas public hazards.
The utility model can be applicable to the vent systems such as various types of explosive motors such as automobiles.
The utility model embodiment.
The low carbon steel plate that with thickness is 0.8 millimeter becomes two-way coniform shell (as in the Figure of description 1), draws the spray trunnion (as in the accompanying drawing 7), turbulator (as in the accompanying drawing 2), energy absorber (as in the accompanying drawing 4,5) and ported sub (as in the accompanying drawing 3,6) with the die stamping that designed, use spot welding and roll welding technology then, be assembled into multifunction silencer by the erection drawing requirement.This silencing apparatus possesses several major functions described in the specification.
Record so that east wind 140 type automobiles are on probation: 1. under engine behavior, improving power when the speed of a motor vehicle is zero is 5%; It is 7% that the speed of a motor vehicle improves power when per hour being the 40-60 kilometer; The speed of a motor vehicle per hour is that to improve power more than 80 kilometers the time be 9-10%; 2. exhaust noise is not more than 75 decibels; 3. eliminate Mars rate 100% in the waste gas; 4. exhale pernicious gases: HC is not more than 3.8 gram/kilowatt hours; CO is not more than 23 gram/kilowatt hours; NOx is not more than 3.1 gram/kilowatt hours.
Claims (2)
1, a kind of profile is the silencing apparatus that shell construction, indoor design have device such as ported sub, it is characterized in that, described shell construction is two-way conical tube and draws the spray trunnion, and described ported sub is the secondary ported sub.
2, silencing apparatus according to claim 1 is characterized in that, turbulator and energy absorber device have also been designed in the inside of said shell construction.
