Traffic noise is the noise that produces by in the motor-driven vehicle going process, is noise source comparatively main in the urban environment noise; And the vehicle exhaust noise is the Main Noise Sources of Motor Vehicle noise, also is the emphasis in the urban environment noise control.For reducing exhaust sound, Motor Vehicle generally adopts muffler to carry out exhaust, and baffler also is the most effective noise reduction means that the control exhaust sound generally adopts.But silencing apparatus inevitably will increase the engine exhaust resistance, thereby affect the performance of motor because structure, reduce its efficient, and particularly during the slow-speed of revolution, output torque is lower, and the moment of torsion export ratio reduces during high rotating speed; How effectively reducing exhaust sound and can guarantee engine performance again, is the difficult problem that silencing apparatus needs to be resolved hurrily.
In the prior art, for addressing the above problem, more is to improve from silencing apparatus itself, such as increasing the silencing apparatus cavity, resonance spare etc. being set in cavity, makes acoustic wave filter structure complicated, increases manufacture cost, and can not effectively address the above problem.
Therefore, need to improve the vent systems of silencing apparatus, can balance effectively reduce engine exhaust noise and guarantee relation between the engine performance, when reducing exhaust sound, effectively promote slow-speed of revolution moment of torsion and high rotating speed power, be more suitable in vehicle according to different the travelling of road conditions, and this exhaust system structure is simple, and cost is lower.
The model utility content
In view of this, the utility model provides a kind of mode of resonance muffler assembly and motorcycle thereof, can balance effectively reduce engine exhaust noise and guarantee relation between the engine performance, when reducing exhaust sound, effectively promote slow-speed of revolution moment of torsion and high rotating speed power, be more suitable in vehicle according to different the travelling of road conditions, and this exhaust system structure is simple, and cost is lower.
Mode of resonance muffler assembly of the present utility model comprises the silencing apparatus resonant cavity, and described silencing apparatus resonant cavity is communicated in the exhaust passage of motor side by side; Side by side connection can be directly separately to connect from the exhaust passage, can also be to be connected to the silencing apparatus suction port in the exhaust passage to the pipeline between the silencing apparatus also, adjusts as required, all can realize the utility model purpose
Further, described silencing apparatus is communicated in the exhaust passage of motor by the exhaust manifold of motor, and described resonant cavity is communicated in exhaust manifold, and is simple in structure, and highly versatile need not change the structure of silencing apparatus and exhaust passage, and is easy to transform.
Further, described resonant cavity is communicated in exhaust manifold by a resonatron, and the resonatron resonant cavity forms resonator system jointly, and resonance effect is better and have possibility of flexible arrangement, more is applicable to flexible light vehicle.
Further, described exhaust manifold is communicated in the relief opening of exhaust passage, and the distance between the connectivity part of described resonatron and exhaust manifold and the relief opening of exhaust passage accounts for the 50-70% of exhaust manifold length; This scope place more can be fit to exhaust pulse rhythm and form the resonance of rule, be beneficial to further noise decrease and improve engine power.
Further, the described resonant cavity chamber volume 2-4 that is engine displacement doubly; The resonance effect of resonant cavity is closely related with its volume and engine displacement, the resonant cavity chamber volume of this structure and the proportionate relationship between the engine displacement can be better realization resonance, the optimum Match that is suitable for air displacement and resonant cavity, play preferably effect, utilize the purpose of the resonant cavity realization model utility of optimal volume.
Further, described resonatron internal diameter is the 33%-67% of exhaust manifold internal diameter, realizes finishing resonance by the tolerance of resonatron and the optimum Match of exhaust manifold air displacement, further eliminates noise and raises the efficiency.
Further, resonatron length is 100mm-300mm; This length numerical value can make resonator gas and Exhaust Gas form better resonance distance, and resonant cavity is better cooperated with silencing apparatus, reaches best resonance effect.
The invention also discloses a kind of motorcycle of using the mode of resonance muffler assembly, described motorcycle is equipped with the mode of resonance muffler assembly.
The beneficial effects of the utility model: mode of resonance muffler assembly of the present utility model and motorcycle thereof, adopt cavity resonator structures to match with silencing apparatus, Pulse tuning is carried out in exhaust, reduce exhaust resistance when eliminating noise, can balance effectively reduce engine exhaust noise and guarantee relation between the engine performance, when reducing exhaust sound, effectively promote slow-speed of revolution moment of torsion and high rotating speed power, be more suitable in vehicle according to different the travelling of road conditions; The utility model is used for motorcycle, effectively reduces oil consumption and surpasses 5%, have preferably energy conservation and consumption reduction effects, and this exhaust system structure is simple, and cost is lower.
