Turbochargers Explained | How Single, Twin-Scroll, VGT & Electric Turbocharger Works?

Turbochargers Explained | How Single, Twin-Scroll, VGT & Electric Turbocharger Works?
Turbocharger:
A turbocharger often called a turbo, is a gas compressor. It is used to force air into an internal combustion engine. A turbocharger is a form of forced induction.
It compresses the intake gas forcing more air into the engine to produce more power for a given displacement. They have greater power density, and they are more efficient. A turbocharger is connected to an engine to give it more power.
At the most basic level, a turbocharger consists of just three major components: the turbine, the compressor, and the bearing system that supports the turbine shaft, connecting the turbine and compressor wheels together.
Working:
As the engine is running, the exhaust gases would otherwise be wasted, but on a turbocharged engine, these exhaust gases pass through the turbo, which spins one fan called the turbine.
The turbine wheel is responsible for converting heat and pressure into rotational force. As the turbine wheel rotates, it spins the turbine shaft, which spins the compressor wheel.
As you see, the compressor wheel has a fixed connection to the turbine wheel via a standard shaft, so when the turbine wheel spins, the compressor wheel also spins. The compressor’s job is to suck air into the turbocharger, pressurize it, and force it into the engine intake manifold. And from there, into your combustion chamber, this air compression helps turbocharged engines produce more power at normal atmospheric pressure.
Components of Turbocharger:
Other main components of a turbocharger are a wastegate, intercooler, actuator bearing system, and oil supply. The wastegate is a valve that controls the number of exhaust gases that flow through the turbine. It regulates the boost pressure and prevents the turbocharger from overspeeding.
Intercooler: An intercooler is used to cool the compressed air from the compressor before entering the engine. This helps to increase the density of the air, which results in more oxygen available for combustion and more power from the engine.
Oil supply and Drain: Turbocharger needs lubrication and cooling. Thus, it's connected to the engine's oil supply system to provide lubrication and cooling to the bearings and shaft. Also, it has a drain system to remove the oil that has circulated through the turbo.
Bearing system: The bearing system is a set of bearings that support the shaft and allows it to rotate smoothly and efficiently. The bearing system also helps maintain the turbocharger's proper operating conditions.

Fun fact: The Roots-style superchargers are older than the piston engine itself and were first in use to pump air into iron furnaces.

[@BigUriel]

A roots supercharger is a lobe pump, they already existed before piston engines, it was only when one was fitted to an engine that it started being called a supercharger. Centrifugal compressors also existed long before, as did turbines. Again it was only when one was fitted to an engine that they started calling it a turbocharger.

You´ve missed the Saab 99 Turbo, developed in 1977, and introduced their 99 Turbo in 1978, with a wastegate, in a ordinary familycar.

[@TheEngineersPost]

Thank you for pointing that out, the Saab 99 Turbo was a significant development for Saab and it was fitted with a turbocharged version of the 2-litre engine. We'll make sure to include it in future videos.

[@N-Lee]

Saab Turbo was my first experience with a turbo vehicle. It was a fun car to drive. I loved feeling that Turbo Power kick in.

[@mrgreyman3358]

In Australia, when a saab arrives off the boat, it takes about 6 weeks before it can go on the sale lot, due to the need to do rust repairs on them. the company I worked for use to do about 20 a week.

What is the cause of not functioning of the lever of the actuator of the turbo

[@moviesenthil]

If it gets to be electric, then we can even use a reciprocating pump, eliminating rotors altogether. Far more efficient and a small pump can produce all the pressure needed. In fact, a little cylinder can store a certain amount of compressed air to open up and supply the extra air to the engine as soon as it starts up.

[@julietasalomon5015]

Electric driven turbo charger is promising and should be further developed by using vfd motors electronically controlled with respect to engine speed or throttle. .Anyway, thanks for the knowledge!

3:01 - I always thought the wastegate was on the cold side (compressor) of the turbo. But the video says it is on the hot (turbine) side.

[@jasonga]

Back in the 90’s you could buy a turbo go a car and it was called ‘TURBO ZET’. They were electric and worked well, you could get a kit for loads of cars!! Dunno what happened to them??

[@AbhishekTiwari-yd5pz]

Turbos power in insane😍

[@christophermarshall5765]

Mercedes were using forced induction in the 1920's, but that was a supercharger, coupled directly to the crank via electric clutch.

[@ripemm5737]

So you hook up your turbo to the air intake and the exhaust manifold? Why doesn’t that make sense to me.

[@nolesy34]

Basically... The exhaust spins it The spinny thing is now spun Air doesn't like to be spun as it gets hotter.. so its fed into a intercooler Then if there to much air it goes su tu tu tu Cannot be simpler

[@shiftygirl6434]

@@nolesy34 lmao perfect "su tu tu tu" colder air is denser air = moar air. otherwise its all just hot air

[@jakemurphy9536]

I agree. Completely ruins an otherwise informative video. If the maker of this video had watched the finished item, he/she would be aware of the poor quality audio, and then done something about it. At least, I hope this would be the case, as poor quality affects audience numbers and viewing figures adversely. I can only surmise they just do not care. Not good enough. I won't be watching any more content from this source.

[@s4ml0ck54]

Saying that turbos are more compact than superchargers is wrong. The full assembly of a supercharger literally comprehends the supercharger and the pulley with the belt. A turbocharger unit in the other hand consists of the turbo, the whole intake manifold, the exhaust from the engine to the hot side of the turbine, the wastegate, the oil line to the turbo and this is the essential; imagine the space that this system occupies with all the sensors and electrical harness, the intercooler, and the pop-off valve with the screamer exhausts.

[@hunnybunnysheavymetalmusic6542]

Turbos are all fine and stuff, probably all engines should have them.

Just a Learning Question on Turbocharger for a V6 3.6l engine in Porsche Cayenne. Can you run an Air Cooler for the Exhaust Gases to help keep the Turbo cool? And Running your Oil through a Transmission cooler be Wise Too? Thanks.

[@krolon9786]

You very much do not want to aircool your exhaust, you're gonna take energy away from it and it won't be able to spool the turbine, plus you'd probably melt the cooler anyway. Consider water cooled turbo. There's also oil coolers if you're worried about overheating your oil. Anyway, if you want to DIY then you have to EXTENSIVELY research the topic of boosting or you risk blowing your engine. Or just give it to someone experienced, boosting is not cheap anyway.
