Turbocharged engine design. Working process of a turbocharged car engine. How a turbine and compressor works? Why is air cooling in an intercooler necessary?
Could u tell me whats the difference between a turbo engine and a naturally aspirated one in terms of accelration? I mean in a NA engine you feel more and more power as u climb the revs while in turbo u feel a steady pull by tje time turbo spools up Thanks
wait you made a mistake! the first case by using a pulley, its the science of a supercharge and not the turbocharge! thats the difference between both system
@@RacanYlum i didnt mention something like u say i did... idk what u talking about and i know very very well how a supercharger works and how a turbo works cause i have both supercharged nad turbo cars (and NA also)... my question was completely different but got my answers long ago
One very important part of turbo systems that was left out was the blow-off valve. When your foot comes off the gas, and the throttle body closes, the turbo is still spinning, trying to force air into the cylinders via the intake manifold. If you can't eliminate that pressure, all sorts of bad things can happen, like blowing the plumbing off the inter cooler. Hence the blow off valve. It is set at a pressure that allows excess pressure to be blown out of the system, but not all the pressure. You want some, so when you accelerate, the turbo doesn't have too much "lag", and will spool up faster. BTW, colder air is more dense, making the air/fuel mixture more explosive.
It would be extremely unlikely to blow off the intercooler plumbing by having no BOV. When the throttle closes the turbo isn't under much load and the air in the system is simply diverted back to the compressor wheel, which makes the turbo flutter noise. The pressure in the system isn't very high at that point. But having no BOV can make the turbo very laggy between gear shifts because the compressor wheel is slowed down between shifts.
Blow-off valve it's definitely handy at the intake side to protect the blades and also loved by tuners especially the atmospheric blow off valves that releases the air into the atmosphere making the famous noise. As far I know on stock mainly wastegates are present which is for to regulate the boost pressure (by routing the upstream flow back into the exhaust), the intercoolers are also typically installed on sport cars by tuners, it's something you won't find either on a regular stock street car.
@@allencarabajal8989 ah ok thanks for that, I will admit my knowledge on diesels is lacking a bit. I know there are a lot of petrol and e85 powered cars running 20+ psi no problems with no BOV
To anyone who wants to turbo their vehicle, unless it was built to take the high pressure from a turbo, you need to upgrade your gaskets and piston rings, otherwise the pressure will break your engine. This is because your stock ratio of air-fuel is usually 14-1. The forced air turns this higher to 20-1 or more. You ideally want an engine built close to a 6-1 ratio.
@@slicelol1463 First you need to check how much pressure your turbo can produce! A (cheap) Turbo wouldn't hurt to add onto already existing engines. However, something of say higher-class Would receive an influx of air. So, the crucial calculation regions Would be the Header Strength. The Pressure waves and it's increased vibration. The pistons (And their rings) The engine block itself (if not heavy duty) To maintain if it would become a critical failure in your setup. Heating especially when using an exhaust setup.

Note that the turbocharger and supercharger were invented in the late 19th and early 20th centuries respectively. The were utilized to enable piston-engined aircraft to operate effectively above 10K feet. Some, like the P-38 Lightning, had both. If you live in a high-elevation environment, it's best to get a vehicle with a turbo and/or blower.
A year ago we bought our first turbo vehicle - a 2019 Kia StingerGT-2 3.3L (twin turbos). Compared to the previous 2.4L 2011 Kia Optima EX we had - the performance is stunning. 365hp/376ft/lbs torque. She pulls nicely.
The primary use of the turbocharger is to operate the engine at sea level on a standard day, regardless of altitude. This is where all reciprocating operate at their best performance. And this is the primary reason this system is used on aircraft engines. Use in automotive is only about 40 years old, but it works there too.
Now just need to do this diagram with blow off valve/ Waste gates. Perfect clear cut, simple and to the point we need more of these! I think one of Camshafts and supercharged Combustion engines would be cool as well!
If you simplify how the turbine side works its pretty easy to visualize how a wastegate works. Exhaust gas goes from engine into the turbine inlet which spins the turbine fan and then the exhaust gas goes out the turbine outlet and from there through your exhaust system and out the car right? The turbine is connected to the compressor via a shaft so when the turbine wheel turns so does the compressor wheel. The thing is if you allow ALL of the exhaust gas through the turbine inlet it will turn the turbine wheel too fast, which turns the compressor too fast (which puts more air into the engine than what you are expecting). The wastegate helps to regulate how much exhaust gas goes into the turbine which limits its speed. So the wastegate sits in between the engines exhaust ports and the turbine inlet. Either on the exhaust manifold (external wastegate) or as a part of the turbine housing (internal wastegate). The turbine gets just enough exhaust gas to spin at the appropriate speed and any excess exhaust gas goes through the wastegate inlet and then to the wastegate outlet where it is either vented to the atmosphere OR piping routes the exhaust gas back into the exhaust system AFTER the turbine.
Fiat used to make smaller diesal turbo motor 1.3 L with 100 HP due to Turbo compression very efficient of fuel and power !!! In India many cars fitted with this engine !!!! Great explanation loved the graphics and narrative!👌👌👌👍👍👍👍
@@skydive7054 think that's kinda his point. I have an 04 WRX and an 02 C5 Z06, the lag of the turbo vs the instant responsiveness of N/A make for a different experience, both a blast to drive though. So i also recommend it :D (and obviously the amount of turbo lag varies depending on the car and what's been done to it, but, I'm speaking in general here)
this is the clearest, most easy to follow way i've ever seen this explained! I never fully understood how a turbo worked before other than someone telling me "It boosts the power by putting more air into the engine" which wasn't exactly wrong, but didn't really explain it at all either. Thanks!
Thank you I am learning ,Planning to turbo charge my motorcycle soon , but I need little bit more time to study and find out what's best fits to my 200cc engine
This was a really good explanation. I had my wife watch this since she asked me how they work and what the difference was between this and a super charger. It was hard for me to explain it so that she could visualize it. So this was perfect.
I have an 08 Acura RDX with a 2.3L 4 cylinder turbo. I love how the turbo can adjust for higher altitudes and provide less drop off in power compared to regular gas engines in the mountains.
funnily enough thats the exact reason turbochargers were made for. Engineers started installing them in planes back in WW2 alongside superchargers to combat power-loss at higher altitudes so the planes could run faster and more powerfully all around.
@@Bonkers-yl2jd I'm starting to see high end cars like Volvo using superchargers+turbos and others using electric motors on turbos to reduce spool time. I've added an Acura MDX Sport Hybrid with 3 electric motors and 3.0L N.A. engine. Pretty much performs the same as a zero lag turbo or supercharged engine with mpgs in the 25-27 range in city/hwy always for a +4500lbs 3 row SUV. The 3.0L suffers a bit at high altitudes; but, the electric motors make up for it.
One of the most important aspects of how a turbocharger works is due to the combustion process expanding the gases exiting the engine so the volume (and pressure) of gas entering turbine housing is much greater than the volume of gas being pumped by the compressor.
That's an important point, because I always wondered how this was not breaking any laws of energy conservation if the power it gives is more than the power it takes
Assuming gasoline is pure octane: C8H18 + 12.5 O2 → 8 CO2 + 9 H2O So you take one mole of a liquid and 12.5 moles of oxygen molecules and get 17 moles of gas product. The octane is a liquid and one mole's volume is .162 L. A mol of any gas at STP (for simplicity) is 22.4 L. That means we start with .162 L of octane and 12.5 x 22.4 = 280 L of oxygen for a total of 280.162 L of reactants and end up with 17 x 22.4 = 380.8 L of products, resulting in a volume increase of about 36%, and this does not yet take into account the expansion from ambient temperatures to 400-500 degrees F, which is far more significant than the volume increase from the reaction. (BTW, been a very, very long time since chemistry class)
I just love the feel of my turbo kicking in on my SAAB 9-3. Such a fun driving experience. It feels like 100 horsepower at low boost, then as you spool it up it feels like you're giving those horses steroids so you get 175 hp. Too bad that turbos add another system that could possibly fail and also shortens the life of your engine.
@@jesukxd8494 absolutely. I just got a car financed, a Mercedes W212 E200 to be exact. It has awesome comfort compared to the saab. But the saab just feels way better to throw around for being so old. The saab definitely has a better driving experience.
I'm at the point in my life that I don't want to break down or have tons of problems with my vehicle & have super low repair costs if problems arise. All this while at least getting 30mpg. My 5 speed '07 Focus ST achieves all the above. Its all about simplicity

Great video, well explained. I have 2 questions, if anybody could please answer: 1 - in a naturally aspirated car, the throttle body should be between the air filter and the intake manifold. Where is the throttle body in a turbocharged car? Between the intercooler and the intake manifold? 2 - what's the air path in a turbocharged engine? Is it air filter -> turbo -> intercooler -> throttle body -> intake manifold -> cylinder? Does that mean that when I start accelerating and the turbo is not working much because of lag, air still passes through turbo and intercooler to reach the cylinders?
yes you would be right about the throttle body, and yes you are right about the order of them as well for the second question, the reason for lag or "turbolag" is because lets say when putting the gas pedal to the floor, air is still needed at that moment to get taken in by the turbo combusted and spit out to spin the turbine of the turbo via exhaust gases which increases the pressure of the system and the air in it which spins the turbine which is connected to the intake turbine, then allowing the intake turbine of the turbo spin faster therefor sucking in more air which equals mo powa babeh
You can decrease turbo lag by putting smaller twin turbos vs a single large one but top end power would be greater on a large single one. It's also very important to take into account the displacement of the engine vs the mm size of the turbo. The colder the air temp is coming out of the intercooler the more power you can make. For max hp you will need forged steel crankshaft, rods or connecting rods and pistons, some applications with very high cylinder pressure will do a process called O-ringing the block and heads to completely seal the cylinder to the head.
Excellent explanation! People should know that a turbocharged engine/car will break down prematurely/earlier as compared to a similar car without the turbo. Turbos put extra pressure on the moving engine parts even when built with stronger or better materials. If you want more power, get the turbo but if you want your engine to last longer don’t get the turbo.
Virtually all factory built turbocharged cars are built now to be reliable under moderate boost pressure. Having said that, the actual amount of pressure used is relatively low as the primary need is for fuel efficiency through best fuel burn. The other option is to overbuild the engine first - make it tough and reliable with heavy duty components, then adding turbocharging. However, this is mega expensive and really only useful if you're aiming for massive power.
Does the increased oxygen content cause a more complete combustion of fuel therefore making it more environmentally friendly? How big of a difference in emissions will this cause? Also, What are some examples of small engines with turbochargers?
It allows the engine to burn more fuel under load and still burn less while idling. So better fuel economy and more power. They're not intended for emissions, but may effect emissions.
I have a 2017 Ford Escape Titanium AWD 2.0 Eco-Boost. It has 245 Hp. 6 speed trans and Sport Mode with Paddle shifting. It runs and drives like a Go-Cart. It catches other cars and SUV's off guard at the light. Shawn.
What is missing in this explanation is the utilization of the thermal energy of the exhaust gases. That is what makes a turbo charger really work. The temperature difference of the gas entering versus the gas exiting the turbine is what supplies the most energy to the system, not the pressure out of the cylinder.
The maximum temperature of the combustion is limited due to reliability. If it werent, you would want as hot air as possible. But since it is limited, you are better off compressing the air at a lower temperature, as it requires less power.
@@Utubesuperstar cooler air is denser at the same pressure than warmer air, but cooler air is not at higher pressure; pressure is an independent variable.
This is going to shorten the lifespan of those little 4 cyclinder engines. I think that's what automakers want, they want you to buy their cars more, and what a great way to do it- get more bang for your buck, but not forever like those old engines! There's no replacement for displacement! There's a reason these big blocks last as long as they do.
One question. In the first iteration of the cycle, does the air pass through the turbo's compressor (ergo, gets compressed) with the same compression ratio as the cylinder (ideally speaking)?
Channel is neat. Another keynote to take from this is that turbo's and extra pulley's give life a good meaning. Thank you for all your videos, I'm a new fan.
Couldn’t you put a pulley on the turbo charger to kick start it before the exhaust gas rotates it, to eliminate turbo lag? Would it also be possible to create a “vacuum charger” that creates areas of low pressure to pull in air for the engine?
So quick question- the heat produced from the turbine/exhaust is inefficient when the heat transfers to the compressor, so than why have them connected so close? Use a longer shaft that doesn't transfer the heat? Or am I missing something?
This was a great video and very informative, but could you explain why it looked like exhaust air traveled into the intake to the turbo, it was at the 2:31 point of the video.
The exhaust air traveled into the intake on the turbo so it could spin the propeller that’s on the inside that is then connected to a shaft that runs to the other side of the turbo that then spins in the opposite direction sucking air into the motor, where you see the smoke come out of the turbo is where the exhaust from the car goes. And then it goes through mufflers etc all the way out the back of the car hope this helped!
So if you increase the driveline In the turbos length you’ll have less heat when the are gets sucked in because it’s farther away from the heat sourced exhaust wheel

this is the clearest, most easy to follow way i've ever seen this explained! I never fully understood how a turbo worked before other than someone telling me "It boosts the power by putting more air into the engine" which wasn't exactly wrong, but didn't really explain it at all either. Thanks!
Thanks for the info Eric Warheim!
thanks for the comment
Nice! I finally understand how a turbo charger works and what is an intercooler!
Excellent
All I know is that turbo goes stutututu and I go happy
I finished watching 2 ads to support
Thanks for explanation
Me too
Thank you I am learning ,Planning to turbo charge my motorcycle soon , but I need little bit more time to study and find out what's best fits to my 200cc engine
Literally the best explanation on the entire internet.
This was a really good explanation. I had my wife watch this since she asked me how they work and what the difference was between this and a super charger. It was hard for me to explain it so that she could visualize it. So this was perfect.
I have an 08 Acura RDX with a 2.3L 4 cylinder turbo. I love how the turbo can adjust for higher altitudes and provide less drop off in power compared to regular gas engines in the mountains.
funnily enough thats the exact reason turbochargers were made for. Engineers started installing them in planes back in WW2 alongside superchargers to combat power-loss at higher altitudes so the planes could run faster and more powerfully all around.
@@Bonkers-yl2jd I'm starting to see high end cars like Volvo using superchargers+turbos and others using electric motors on turbos to reduce spool time. I've added an Acura MDX Sport Hybrid with 3 electric motors and 3.0L N.A. engine. Pretty much performs the same as a zero lag turbo or supercharged engine with mpgs in the 25-27 range in city/hwy always for a +4500lbs 3 row SUV. The 3.0L suffers a bit at high altitudes; but, the electric motors make up for it.
Best 3D explanation ever~ Simple to understand and nice 3D graphics explanation. Great Job!!!
Thanks
Thanks for the lore explanation
One of the most important aspects of how a turbocharger works is due to the combustion process expanding the gases exiting the engine so the volume (and pressure) of gas entering turbine housing is much greater than the volume of gas being pumped by the compressor.
That's an important point, because I always wondered how this was not breaking any laws of energy conservation if the power it gives is more than the power it takes
Assuming gasoline is pure octane:
C8H18 + 12.5 O2 → 8 CO2 + 9 H2O
So you take one mole of a liquid and 12.5 moles of oxygen molecules and get 17 moles of gas product.
The octane is a liquid and one mole's volume is .162 L. A mol of any gas at STP (for simplicity) is 22.4 L. That means we start with .162 L of octane and 12.5 x 22.4 = 280 L of oxygen for a total of 280.162 L of reactants and end up with 17 x 22.4 = 380.8 L of products, resulting in a volume increase of about 36%, and this does not yet take into account the expansion from ambient temperatures to 400-500 degrees F, which is far more significant than the volume increase from the reaction. (BTW, been a very, very long time since chemistry class)
I just love the feel of my turbo kicking in on my SAAB 9-3. Such a fun driving experience. It feels like 100 horsepower at low boost, then as you spool it up it feels like you're giving those horses steroids so you get 175 hp. Too bad that turbos add another system that could possibly fail and also shortens the life of your engine.
Saabs are just different ♥️
I have 175 hp Saab 9-3. Great car
@@jesukxd8494 absolutely. I just got a car financed, a Mercedes W212 E200 to be exact. It has awesome comfort compared to the saab. But the saab just feels way better to throw around for being so old. The saab definitely has a better driving experience.

@@ab-edit5486 The ford focus isn't really a US car, it was designed by euro ford and is a pretty reliable car.
@@liamholcroft7212 I had a 2006 Ford mondeo made in gemrnay and it was an unreliable piece of trash. Sometimes the alternator (made by Valeo) (battery charger) giving up and then the whole air cidntioning setup breaking down from compressor to leak in condensor coil which require taking apart the whole dashboard for costly repairs. Then engine problems of various kind to water body giving up to radiator exploding to radiotor plumbing problems to engine over heating to engine getting blown. It was the worst most unreliable car ever. Even when it was just 4 years old. Never going near amaerican trash cars again.
One of the many reasons why I loved 2Fast2Furious so much and some of the others. They showed off the inside of the engine and everything through out into the exhaust.

A belt going from the crankshaft to the compressor shaft is not a turbo charger, that's called pro-charging
ProCharger is a brand centrifugal supercharger is what you’re describing.had one on my last mustang.
Yeah I was hoping someone else saw that because I knew it wasnt right
People should know that the turbo can spin up to 200,000 rpms, that's also important to know
Excellent video 🏆
love the ingenuity behind all these techs
which about to be obsolete soon enough
Great video, well explained. I have 2 questions, if anybody could please answer:
1 - in a naturally aspirated car, the throttle body should be between the air filter and the intake manifold. Where is the throttle body in a turbocharged car? Between the intercooler and the intake manifold?
2 - what's the air path in a turbocharged engine? Is it air filter -> turbo -> intercooler -> throttle body -> intake manifold -> cylinder? Does that mean that when I start accelerating and the turbo is not working much because of lag, air still passes through turbo and intercooler to reach the cylinders?
yes you would be right about the throttle body, and yes you are right about the order of them as well for the second question, the reason for lag or "turbolag" is because lets say when putting the gas pedal to the floor, air is still needed at that moment to get taken in by the turbo combusted and spit out to spin the turbine of the turbo via exhaust gases which increases the pressure of the system and the air in it which spins the turbine which is connected to the intake turbine, then allowing the intake turbine of the turbo spin faster therefor sucking in more air which equals mo powa babeh
@@epicalty8474 thanks for the answer! Moh powah babeeehhh!
You can decrease turbo lag by putting smaller twin turbos vs a single large one but top end power would be greater on a large single one. It's also very important to take into account the displacement of the engine vs the mm size of the turbo. The colder the air temp is coming out of the intercooler the more power you can make. For max hp you will need forged steel crankshaft, rods or connecting rods and pistons, some applications with very high cylinder pressure will do a process called O-ringing the block and heads to completely seal the cylinder to the head.
This was really cool and informative. But what software did you use to build the 3d models? It looked amazing.
I don't know
probably blender
Thank you 🙏
Hey very nice video.
Thanks to you I now understand how it really works.
It would be cool If you could explain how a supercharger works
Thanks, I'll try
Excellent explanation! People should know that a turbocharged engine/car will break down prematurely/earlier as compared to a similar car without the turbo. Turbos put extra pressure on the moving engine parts even when built with stronger or better materials. If you want more power, get the turbo but if you want your engine to last longer don’t get the turbo.
Most modern engines are turbo-charged. They have been effective in the past and soon will be the only type of engine in the future
Technically you are correct but the difference is negligible and doesn't really apply for most modern day turbo cars that are designed for it.
@@liamaldous2624 diesel turbo is reliable
Air çharge coolers are neat
Virtually all factory built turbocharged cars are built now to be reliable under moderate boost pressure. Having said that, the actual amount of pressure used is relatively low as the primary need is for fuel efficiency through best fuel burn.
The other option is to overbuild the engine first - make it tough and reliable with heavy duty components, then adding turbocharging. However, this is mega expensive and really only useful if you're aiming for massive power.
Does the increased oxygen content cause a more complete combustion of fuel therefore making it more environmentally friendly? How big of a difference in emissions will this cause?
Also, What are some examples of small engines with turbochargers?
It allows the engine to burn more fuel under load and still burn less while idling. So better fuel economy and more power. They're not intended for emissions, but may effect emissions.
Great information
I have a 2017 Ford Escape Titanium AWD 2.0 Eco-Boost. It has 245 Hp. 6 speed trans and Sport Mode with Paddle shifting. It runs and drives like a Go-Cart. It catches other cars and SUV's off guard at the light. Shawn.
Now take this system and add more turbos. More turbos makes more power then you gap the opposition. ;)
Quattro turbo :-)

i tell you how the turbo work
the air go in ther, through there, it go to the coola, it go out of ther and there it go stutututu
sick video
Thank you!
What is missing in this explanation is the utilization of the thermal energy of the exhaust gases. That is what makes a turbo charger really work. The temperature difference of the gas entering versus the gas exiting the turbine is what supplies the most energy to the system, not the pressure out of the cylinder.
Mushroom oil is the best for turbos
Great video.👍🏻👍🏻
Thanks
Amazing video!
Thanks
The cooling part was unexpected for me. I thought it's similar to smithing where we want our air to be heated, before forcing it to the forge.
The compressed air is cooled to reduce chances of pre-detonation and increase efficiency (just see PV curve of a compressor with intercooler).
The maximum temperature of the combustion is limited due to reliability. If it werent, you would want as hot air as possible. But since it is limited, you are better off compressing the air at a lower temperature, as it requires less power.
Cooler air is denser hence higher pressure and more potential and thus kinetic and thermal energy
@@Utubesuperstar cooler air is denser at the same pressure than warmer air, but cooler air is not at higher pressure; pressure is an independent variable.
Turbo goes WOOOSH CHUCHUCHUCHU and you go fast. That's all you need to know.
I need to learn more about this
Nice video, thanks ,👍
This is going to shorten the lifespan of those little 4 cyclinder engines. I think that's what automakers want, they want you to buy their cars more, and what a great way to do it- get more bang for your buck, but not forever like those old engines! There's no replacement for displacement! There's a reason these big blocks last as long as they do.
praise our LORD 🧠 thank you Jesus Christ for being our savior
AMEN
Amen
Very good video.
One question. In the first iteration of the cycle, does the air pass through the turbo's compressor (ergo, gets compressed) with the same compression ratio as the cylinder (ideally speaking)?
Channel is neat.
Another keynote to take from this is that turbo's and extra pulley's give life a good meaning.
Thank you for all your videos, I'm a new fan.
Couldn’t you put a pulley on the turbo charger to kick start it before the exhaust gas rotates it, to eliminate turbo lag? Would it also be possible to create a “vacuum charger” that creates areas of low pressure to pull in air for the engine?
Such combinations can be used on sports cars, but for a regular car it will be expensive.
Thanks. Well done. Recommend this explanation😊😊😊😊😊
Thanks
Very nice visuals
Thanks
At this rate, “But you didn't have to cut me off” just starts playing itself at these videos.

Awesome Video
Thanks
Great video
Thanks
also look into wastegates and blow off valves to get the full picture of a turbocharged engine
Does bigger throttle body do quite the same?
Thank you very much!!! :)
So quick question- the heat produced from the turbine/exhaust is inefficient when the heat transfers to the compressor, so than why have them connected so close? Use a longer shaft that doesn't transfer the heat? Or am I missing something?
Can you give some information about front wheel drive cars and how they work. We do love to watch it.. 😃
I will try to do it
This was a great video and very informative, but could you explain why it looked like exhaust air traveled into the intake to the turbo, it was at the 2:31 point of the video.
The exhaust air traveled into the intake on the turbo so it could spin the propeller that’s on the inside that is then connected to a shaft that runs to the other side of the turbo that then spins in the opposite direction sucking air into the motor, where you see the smoke come out of the turbo is where the exhaust from the car goes. And then it goes through mufflers etc all the way out the back of the car hope this helped!
What happenes when you put a gearing on the part where the windt Thing go’s on ? You can dubbel the windt producing right ?
So if you increase the driveline In the turbos length you’ll have less heat when the are gets sucked in because it’s farther away from the heat sourced exhaust wheel
thx, finally get it
When i was 15 i bought my 1st car a 1980s honda accord hatchback and not 1 year later me and few buddies added a junk yard built turbo to stock motor we did work on previous...it was a rocket and gave me like 75 to the gallon...gave this car to an uncle that was moving back to Guatemala...car still his daily driver...its original burgundy still with stick .....best fun ever...
