SILENCERS FOR TWO WHEELER & THREE WHEELERS
[code no.3850]
Automobile silencer is an essential part of any automobile.The main function of silencer is to reduce noise of the vehicle.
An automobile vehicle, while running on a road, produces an intolerable noise, which, is otherwise controlled by a proper noise reducing device, will create a hugenoise. The device, used to minimise this noise is called 'Silencer' this device bring the noise of an auto engine to much extract. Until comparatively recently, the design of silencers for automobiles & transport vehicle engines has been largely empirical based unreactive and/or dissipative principles. Reactive silencers work on the principle of reflecting sound energy back towards the source. (But may also provide some energy dissipation by crossflow depending on the design). Dissipative Silencers incorporate chambers or sections lined with sound absorbent materials in which sould energy is absorbed. (and turned into heat).
Four basic type of auto engine silences in simplified diagrams are sketched.Each have numbers variants. The simplest ones-the expansion chamber & resonator are basically tuned filters with narrow band, attenuation wiliest still retaining straight through geometry (and thus minimum back pressurlers). The reversed flow (or multipan) is capable of even wider and attenuation (particularly) at law - frequencies), but usually at the expense of higher back pressure because of the torthnous gas flowpath con which , the per furnace of silencer largely depends).
