Purpose of a Turbocharger - Explained

[imthaman1234]

so basically a turbo blows exhaust gas back into the engine to create a bigger explosion hmm very interesting

[sage1wt]

So the exhaust pressure from the cylinder is used to bring in more Air (by spinning a tubine) right? So is the exhaust waste is confined from the air; therefore, the exhaust doesn't make another cycle through the cylinder?

What a great video! I wish I knew more about this stuff

[EngineeringExplained]

@sage1wt The exhaust leave the engine, so no, it does not make another cycle through the engine (cylinder). However, since most engines use EGR (exhaust gas recirculation) some of the exhaust actually does go back into the engine. This is for emissions purposes, and I will eventually have a video on this topic.

[sage1wt]

why dont you get more veiws? I have always wanted to take a class or two about engines at my high school; although, there is no need to because you have "explained" Everything I want to know. Thanks You

@sage1wt Honestly I've been surprised with the amount of views I've gotten. Considering my channel is less than a year old, I'm pretty proud of 2000+ subscribers. But hey, if you want to spread the word, that'd be awesome! :)

[shunjingus]

Does the fuel/air mixture ratio remain constant when the turbo is in effect to when it's not? Does the car have a sensor on the current boost level in order to increase the amount of fuel injected into the piston at the same throttle position?

[EngineeringExplained]

@shunjingus Yes, the ratio attempts to stay the same. There are sensors measuring the amount of air going into the engine, which then tells the ECU to spray more fuel.

[SoyAussie]

ive always wondered, does adding a turbocharger help or hurt your mpg ?

[EngineeringExplained]

@SoyAussie Well the intention is to increase power by increasing the mass of air in the cylinders so that you can burn more fuel. However with a smaller engine that is turbocharged, you can create equivalent power to larger engines, and get better fuel economy when you want to (just don't floor it and shift early).

[fredd164]

Could you describe how an alternator functions in a car?

[EngineeringExplained]

@fredd164 Definitely on the to-do list. Just need the time!

[JayBird90210]

@fredd164 simplest explanation I can think of right now. Your alternator has a magnet and surrounding that magnet is alot of coiled copper a.k.a a stator. Now once you start the engine the drive belt is attached to the magnet and spins the magnet really fast and since we know that when a magnet that moves surrounded by copper coil produces electricity that electricity is sent to your battery to charge it...... BTW I am open to any corrections concerning terms and science from anyone

you are amazing.



[David20931]

dude these videos are great!

dont stop making them

[lindaleparkrolo]

rapid expansion, not an explosion...although I think running 100% methanol will cause that or detonation.

[yamenad]

keep it up bro :) i like your videos, Watched it them all :)

i think a pre written script will make you more pro in this business :) and a slightly better lighting too :)

you got great knowledge and ur sharing and teaching is appreciated.

[EngineeringExplained]

@yamenad Lighting has definitely been an issue, my camera doesn't seem to have enough lighting no matter how many I put in the room (it was cheap). Also, I wanted this to seem as if my friend has asked me how something works, and I'm simply responding in a manner that's easy to understand. What I say is what I know; it's not something I've memorized and rehearsed. Although it may seem more rugged, I believe it's easier to follow. Thanks for your support!

[joeslimon]

Good video, although I would differentiate between gauge pressure and absolute pressure. When you first said 15psi, I was assuming absolute.

[EngineeringExplained]

@joeslimon Apologies, I tried to make it clear by saying 15 (or whatever number) psi "of boost" so that it is seen as additional.

[ErnieL23]

great video :p

[davidle24]

Yeah, another good video!

[nerdypielover]

Very good explanation, you deserve alot more views, you described all the aspects of how it works, it was easy to understand, and well presented all together

[EngineeringExplained]

@nerdypielover Thank you! I'm just getting started with this channel so I'm hoping it builds interest. Throw suggestions at me for future videos anytime!
