11. Blow-off valves or BOV or similar
Since people insist upon asking about these devices, they need to be discussed ... The purpose of a "blow-off valve" or "diverter valve" on a gasoline engine is to give boost pressure someplace to go when the throttle plate is abruptly closed, to prevent operating the compressor in the "surge" regime. Since a diesel engine doesn't have a throttle plate, a gadget like this serves absolutely no purpose and has no business anywhere on a diesel engine. "But I like the cool noise ..." Too bad, this discussion is focused on things that WORK. Even if you manage to find some way to make such a device work, the noise of people "in the know" laughing at you because they realize that it has absolutely no place on your engine will drown out the noise that the device itself makes.
Asa zice pe un forum dedicat diesel, dar am o intrebare pentru cei care se pricep mai mult ca mine. Poate ca daca iau piciorul de pe acceleratie, aerul in exces tot intra in cilindri deoarece nu este restrictionat de o clapeta de acceleratie, dar daca merg cu o anumita viteza si apoi pentru ca sa incetinesc aplic frana de motor? Toata presiunea pe care a dat-o turbina pana atunci la viteza mare nu se intoarce inapoi spre turbina? Si atunci, in situatia asta nu ar fi utila valva asta care elibereaza presiunea in exces?
