Scooter Silencer - What Is Inside A Silencer Lambretta Scooter - смотреть онлайн

Scooter silencer lambretta. In this video I have shown what is inside of it. The price of this silencer is 1200 Indian rupees. A muffler (silencer in many non-US English speaking countries) is a device for decreasing the amount of noise emitted by the exhaust of an internal combustion engine. Mufflers are installed within the exhaust system of most internal combustion engines, although the muffler is not designed to serve any primary exhaust function. The muffler is engineered as an acoustic soundproofing device designed to reduce the loudness of the sound pressure created by the engine by way of acoustic quieting. The majority of the sound pressure produced by the engine is emanated out of the vehicle via the same piping used by the silent exhaust gases. The emitted noise is abated by a series of passages and chambers lined with roving fiberglass insulation and/or resonating chambers harmonically tuned to cause destructive interference, wherein opposite sound waves cancel each other out. An unavoidable side effect of muffler use is an increase of back pressure, which decreases engine efficiency. This is because the engine exhaust must share the same complex exit pathway built inside the muffler as the sound pressure that the muffler is designed to mitigate. Some vehicle owners remove or install an aftermarket muffler when engine tuning in order to increase power output or reduce fuel consumption because of economic or environmental concerns, recreational pursuits such as motorsport and hypermiling and/or for personal aesthetic acoustical preferences. Although the legality of altering a motor vehicles OEM exhaust system varies by jurisdiction, in many developed parts of the world, modification of a vehicles exhaust system is usually highly regulated if not strictly prohibited. When the flow of exhaust gases from the engine to the atmosphere is obstructed to any degree, back pressure arises and the engines efficiency, and therefore power, is reduced. Performance-oriented mufflers and exhaust systems thus strive to minimize back pressure by employing numerous technologies and methods to attenuate the sound. For the majority of such systems, however, the general rule of “more power, more noise applies. Several such exhaust systems that utilize various designs and construction methods: Vector muffler - for larger diesel trucks, uses many concentric cones or for performance automotive applications, using angled baffles to cause exhaust impulses to cancel each other out. Spiral baffle muffler - for regular cars, uses a spiral-shaped baffle system. Aero turbine muffler - creates partial vacuums at carefully spaced out time intervals to create negative back pressure, effectively ‘sucking’ the exhaust out of the combustion cylinders.
