Malo po ebay-u brskam in ker ne vem kje bi denar zapravu sem naletel na zanimivo zadevco ki se ji reče blow pop off ventil. Kakor sem razumel je funkcija tele napravce predvsem zvočna. Ali se mar motim?

Ali imaš avto s turbino?
Ta ventil namreč spušča odvečen pritisk, ki ga ustvari turbina, da ti nebi uničilo motorja.
Tukaj si preberi o tem kako deluje turbina in kakšni so pomembni deli, ki pašejo zraven. Razloženo imaš tudi to, zakaj blowoff ventil zraven turbine in kakšno vlogo igra.

A blowoff valve is a pressure release system present in turbocharged engines. Its purpose is to prevent compressor surge, and reduce wear on the turbocharger and engine. Blow off valves (BOV) relieve the damaging effects of compressor "surge loading" by allowing the compressed air to vent to atmosphere, making a distinct hissing sound.
A compressor bypass valve (CBV), also known as a compressor relief valve or diverter valve, is a vacuum-actuated valve designed to release pressure in the intake system of a turbocharged vehicle when the throttle is lifted or closed. This air pressure is re-circulated back into the non-pressurized end of the intake (before the turbo) but after the mass airflow sensor.
A blowoff valve, (BOV, sometimes "hooter valve", not to be confused with a bypass valve) performs the same task but releases the air into the atmosphere instead of recirculating it. The blowoff action produces a range of distinctive hissing sounds, depending on the exit design. Some blowoff valves are sold with a trumpet-shaped exit that intentionally amplifies the sound. Some turbocharged vehicle owners may purchase a blowoff valve solely for the auditory effect even when the function is not required by normal engine operation. Motor sports governed by the FIA have made it illegal to vent unmuffled blowoff valves to the atmosphere.[citation needed]
Blowoff valves are used to prevent compressor surge, a phenomenon that readily occurs when lifting off the throttle of an unvented, turbocharged engine. When the throttle plate on a turbocharged engine closes, the high pressure air in the intake system is trapped by the throttle and a pressure wave is forced back into the compressor. The compressor wheel slows rapidly and may even stall, and the driver will notice a fluttering air sound. The rapid slowing or stalling stresses the turbo and imparts severe turbo lag if the driver accelerates immediately after the surge event.

lisko napisal/-a: Ventil , ki pa varuje motor pred velikim pritiskom polnjenja turbina pa se imenuje By pass ventil. O delovanju le tega pa prihodnjič

sej se mi je zdelo,da je isto,ampak lisko je na koncu napisal tole:lisko napisal/-a: Ventil , ki pa varuje motor pred velikim pritiskom polnjenja turbina pa se imenuje By pass ventil. O delovanju le tega pa prihodnjič
se pravi,da z diverterjem (oz. bypassom) sigurno ni mislil na tapravo stvar...mogoče ga je pa zamenjal z wastegate-om
Sven napisal/-a:Na posnetku je pred leti posneta lancia delta, pri kateri se dobro tudi sliši piskanje blow off ventila ob spuščanju gasa (00:24-00:26 ).
Upam, da se da downloadat, če pa ne pa lahko komu pošljem, ki bo to dal na server.
