Njegova naloga je pa ta da, ko ti presaltas, npr v obmocju najvecjega boosta, ta ventil spusti boost ven (medtem ko originali spuscajo v auspuh), zato da turbina ohrani tiste vrtljaje, tako da ko spet zahtevas od motorja moc, jo tudi imas.

Kuul, kolk kaj stane in kdo ti mora to notri našraufat?

Pa a je kdo kaj tebe vprašal? s***** s tem sarkazmom nekam, ker samo smetiš forum.

Ja, koliko stanejo kaj take zadeve in KDO ti to notri našraufa (v smislu, ali si lahko sam ali rabiš kakšno posebno znanje za to pizdarijo). Now, be gone.

Blow-off valves or BOV or similar on diesel engines

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.

Installation: Impossible. Cannot be made to work even if you insist upon it.

Advantages: None.

Disadvantages: Won't work. People who actually know how a diesel engine works will laugh at you for even considering it. You are your own warranty.

Cost factor: Too much, all things considered.

Cautions specific to this modification: Won't accomplish anything.

Suggested modifications in parallel: Irrelevant.

"Bang for the Buck": One hundred percent total waste of time and money.

What if I want more? Do something that actually accomplishes something ...

Can you put a blow off on a diesel engine?

A blow-off valve is designed to prevent compressor surge on turbo-charged engines. Compressor Surge occurs when the engine's THROTTLE PLATE is suddenly closed, giving the Charge from the Turbo compressor, no where to go. So the blow-off is plumbed in somewhere between the Compressor's outlet and the Engine's Throttle body, allow unwanted Boost Pressure to be vented to Atmosphere or Intake stream before Compressor inlet. So, that being said, it should be obvious why most modern Turbo-charged, direct-injected Diesel Engines would have no need for a "blow off valve". A diesel engine is controlled by fuel, thus not requiring it to have a "intake air throttle plate". In a diesel engine, all mixing of FUEL/AIR occurs in the Combustion Chamber, by design the Diesel operates in EXCESS AIR situations, it can pump up to 600X times more air than it needs @ low idle. A Diesel builds peak power and Manifold Boost when UNDER-LOAD, so when you cut fuel to that engine while under load, the Manifold boost still has a place to go since the engine is still pumping air. The manifold boost tends to drop off quickly since it is being displaced by the cylinders, and since the turbine drive pressure will be less as well. This is why diesels do not provide "engine braking" without the use of devices, (i.e. Jake Brake, Exhaust Brake.), where as a gas engine provides said "engine braking" ability.

Exceptions Occur
A few diesel engines of the past few years have used a throttle plate, mainly as part of some solutions in order to meet new diesel emissions standards. this is another topic really. I'm an off-road diesel tech, so I'm not really familiar with these light-duty/automotive diesel that utilize the throttle plate, so I won't say for sure if they would benefit from a Blow off valve.

Ojoj, not again. Na dizlih bov nima smisla, ker dizel nima lopute za plin. Imas sicer nekaksne simulacije BOV-a za dizle, ki pa samo simulirajo un pfsssst... kot da bi en radio noter obesil, toliko ucinka ima to.

Ce hocete pravo stvar, bo treba turbo bencinca nabavit
