You don't say? You may wish to review this paper published by the Lund Institute of Technology. Please note the word "vacuum" does not appear in it.
Further to your "forced induction" comment...
From Para. 1.1.3, in part: |
Are you seriously arguing the how a CCV system works or the benefit of vacuum pulled on a crank case? Like seriously?
Diesels don't make MANIFOLD vacuum.
Does the turbo suck or blow into the BMW CCV tube? It pulls, right? The higher the turbo spins, the more it sucks, right? It's sucking gases from the crankcase. Right? Kind of like a vacuum, no?
If you read ALL of my post, you'd see where I mention pulling vacuum with the exhaust to avoid pulling blow-by back into the intake. Regardless, both methods work excedingly well in performance application when used in concert with a quality catch can.
Venting to atmosphere will increase blow-by in forced induced applications. Piston ring seal can be weakened without crank case vacuum, boost pressure then passes by the rings leading to increased crank case pressure, blow-by and power loss.
Might want to do a few more google searches, uber!
