3:08 is a supercharger, not a turbo. A supercharger is driven by the crankshaft via a belt, because of this, a supercharger is always turning, and has no lag, unlike a turbo that is driven by the exhaust gases and must spool up before giving power.

Thanks for using my suggestion!❤

👍

A 2016 Freightliner Cascadia with a 15L Detroit Diesel has around 24 psi boost.

So am i only one or others also notice, alfred buchi invented turbocharger, okay so what ? He started his work in 1910 but got patented license in 1905.. 🤔 how is that possible without even making it ... 😮

[@SurvivenTerry]

Also you cant just slap a turbo on anything without some special tuning and adjustments. The same concept goes for nitrous boosting.

[@ontheroadagain4773]

It already has been told that the thing at 3:08 is a mechanical supercharger, in this case a belt-driven screw compressor that rotates at pretty much same rpms as the engine. And at 5:03 is in fact an electric powered supercharger, not a turbo either. "Turbo" itself actually means the exhaust powered turbine. The advantage of an electric powered compressor is that it starts to wortk immediately when you press the trottle, before the engine itself reacts, faster than even a supercharger. And a computer controlled electric powered compressor can give the right torque at any speed and load.

Have you heard of a "turbo compound" engine? Scania introduced the 11 litre DTC11 engine in 1990 that produced 401 hp, around 25 hp more than the normal intercooled DSC11 engine. It had a normal turbocharger + another exhaust turbine connected in series with the first one. The power from this turbine was mechanically transferred by gears directly to the crankshaft. This is indeed a more complex construction and I don't know how much this technology has been used.

[@zbaktube]

This was the one that was a bit loudish "whistling" engine, wasn't it? I remember one Scania from my childhood that has that funny airy noise, but went like a bullet...

[@ontheroadagain4773]

@@zbaktube It's possible, but the 14 litre V8 of that time also had a distinct whistling turbo sound. Already in 1990 the strongest V8 produced 500hp!

@@ontheroadagain4773 Those were the trucks! I remember first having one to my father. It was like 10 years later? Not sure. It had tempomat. And first scared the sh.t out of me when we went uphill. I was used to when the road was rising our old truck was slowing down. But not with that truck, it gave automatically a bit of gas and just run uphill without any effort. I thought first the truck engine got runaway and we wont be able to slow it down 😀 Back a bit to the DTC11, was the extra exhaust turbine switchable? How I remember that the extra whistling sound (over the turbo whistling) only came when the truck went uphill... But I was a little boy, my memories just aren't that clear...

[@ontheroadagain4773]

@@zbaktube I have no experience from the DTC11, but the text about it tells the turbine has "hydraulic switching". Unfortunately the history book about Scania I have is in german and I'm not good at it. I had to use Google. There is a good exploded view of the engine in the book but it isn't good enough to show exactly how this switch works.

[@zbaktube]

​@@ontheroadagain4773 Can you send me the exact title of the book? I had my fair share with the German language, If I can find a cheap one I would buy it 🙂

[@brianburgess3231]

What about an aircraft?

[@user-poopee]

Would be epic to see

[@anesuchirima96]

😮 it also has a turbo?

[@brianburgess3231]

usually super

[@ProCoder11996]

Turbocharger only exist in piston engine aircraft i guess, As turbine engines are very different

[@brianburgess3231]

@someonez768 my dad had two piston engine aircraft, uncle had 4 .. none were turbo charged.

Peace be upon you. My husband is a truck driver and he is looking for work. Can you help me with any information? He has a tourist visa, but he wants to live in Canada and work there. If anyone is looking for workers, please, even if it is in the garbage, it is normal.
