I was wondering. Could the vanes of the VGT be made of ceramic? It would be light and extremely heat resistant and should be reliable as the vanes are not subject to mechanical stresses and pressures other than movement, i.e., opening and closing.
the steel turbocharger is powerful enough, the unit is already small and light, nowhere in engineering, even planes and rockets do not use ceramics. the answer is NO.
What I want know the vanes should be closed or open little bit I want adjust the screw in my turbo but I want know if stays open little bit or closed at all thank you
At low engine speed, the vanes are in the “closed” position narrowing the gap between them which accelerates the exhaust gas onto the turbine wheel. At high engine speed the vanes open up slowing the exhaust gases, which prevents the turbocharger over-boosting.
I guess you get a green light for overall information, but since I was just here for a clearer how VNT turbos work portion I had to skip almost half your video... Otherwise it was great thanks...
Thanks for that Tom. I have not long ago modified gtb2260v turbo (but not fitted yet) to run a mechanical actuator over the electronic item, I just wanted to make sure I have the actuator sat on the right side of the turbo to operate the veins to the correct position. Now I'm thinking I may have it wrong!
Thank you for this video! Very good explanation
Excellent video. Now I get it 😀
I like it.

Ceramic will shatter

So this is the thing that makes turbo diesel truck sounds videos sound so odd

Sebenarnya turbo jet adalah mesin pengubah fasa bukan tutupnya bukan
When the motor is sitting idling will the veins be at a open position and start to close up as the revs increase or the other way round??
Other way round,its almost closed(1-1,5mm)gap at idle,and slowly opens up to make the target boost.Fully opened at max boost and prevent overboost!

And Porsche had this tech so long ago.
Tapi beda dengan destillasi bertingkat uap!!
Secara udara Kotor around..
Jadinya mirip raja minyak..

That power curve is bogus. It maintains the same gradient even though the torque has started reducing.
I hate this idea! My turbo vanes are stuck shut!
use a carbon cleaner
Mr Muscle oven cleaner- seriously!
