Background technology
In the course of work of internal combustion engine, need to discharge waste gas after the high-pressure gas expansion in cylinder, so as to fresh air
Into.When air bleeding valve is just opened, the high pressure combustion gas in cylinder is sprayed with very big flow velocity, and combustion gas has at a relatively high energy
Amount, can produce a high frequency noise.Air-flow can be produced by being collided when narrow positions or the turning of discharge duct with tube wall simultaneously
Raw vortex noise.According to the influence of actual exhaust air length of tube and discharge frequency it also occur that the air column resonance noise in blast pipe.
The sound pressure level of exhaust noise is with the mean effective pressure when capacity of internal combustion engine, power output, moment of torsion and internal combustion engine
Deng relating to parameters.In the case where rotating speed is constant, the raising of live load can cause the raising of exhaust noise.The raising of rotating speed
Exhaust noise can be increased, because after rotating speed improves, the capacity of internal combustion engine accordingly increases, while also exacerbates vortex and make an uproar
Sound, these factors will all increase the level of noise of internal combustion engine.By contrast, the noise of diesel engine is bigger than gasoline engine in internal combustion engine,
Because diesel engine has larger mechanical noise, and in-cylinder pressure of the diesel engine in exhaust valve opening is bigger.Due to bavin
The exhaust noise magnitude of oil machine is higher, so generally installing exhaust silencer in diesel engine exhaust system.
In addition, containing hundreds of different compound in diesel engine vent gas, not only smell is strange for this gaseous effluent, and
And make us dizzy, nauseous, influence the health of people.It is general using catalyst by vent gas treatment into very low stain degree gas again
Discharge.
As tail gas goes out blast pipe, many smokeshade can be taken out of and together discharged, produce pollution, and block blast pipe.
