  • The best explanation comes from Jeremy Clarkson:

    ''exaust gas is diverted into the turbocharger, witchcraft happens and then you go faster''

  • Now I'm even more confused.....

  • I'm a computer engineer in an office, and I don't know anything about this stuff.

  • @WoWzergKorialstrasz "Atomize the AIR"? I don't think so.. more like forcing more air.. which gets the mixture closer to the Stoichiometric ratio and that is what helps fuel economy.

  • very smart guy, i wanna be a mechanic one day, hopefully as good as him

  • Not to criticize, but the only thing that was left out was that the very end: the other limit of power is when the engine is at too low of an RPM to get the turbo spinning (at a high enough RPM, if spinning at all), thus creating what's called turbo lag.

  • @TheGeek1028 I would think that in this case, as with many others, people speak only about peak horsepower and not about the whole powerband.

  • The cars in this video almost made me want to discredit it's integrity, (not the S2000, the old Civics) but this guy is pretty damn smart.

  • WTF so if it helps burn the leftover fuel. Why does a turbo(if not on the car stock) make it not pass smog?

  • @KeepItBRUTAL1 they view it in a "gas guzzler" type of way, which as you said makes zero sense, just another way to cut down on street racing. so glad my state doesn't have smog, yet....

  • Der Apotheker am Turbolader erzeugen oft Probleme mit dem Netzwerk als Teil eines Fahrzeugs mit Ladeluftkühler ausgestattet.

  • TURBOLADER jemand den Traum in den Benziner. Die Gesellschaft ist nicht zu vergeben, die Entscheidung. Die Verschwendung von Ressourcen durch die Verbrennung von Brennstoffen und Materialien, um Druckluft liefern INTERCOOLER noch heißer als 80 Grad Celsius und einer Temperatur von weniger als 99% der Wärmekapazität des Motorblocks. Der Zylinder und der Zylinder mit Druckluft vom Turbolader zu fahren.

  • Atomises the air? The air is already a gas you dimwit. It atomises with fuel AFTER it has entered the throttle body.

  • Please do the superchargers too

  • Good job Sam, been doing this for over 20 years in ATL

  • so, let me get this clear. the exhaust gasses go through the turbo rather than directly to the exhaust, and burn any extra gas?

  • @robbinshood79 No.

    The exaust gases make the turbo spin. Spinning the turbo spins another turbine on the cool side of the turbo. That turbine has a whole different tubing system, and its objective is to bring in more air, wich will be forced into the engine with the fuel for the combustion.

    So, instead of having normal airflow to the inside of the engine you have a turbine forcing much more air inside. More oxigen = better burn.

  • @Wyrmnax great, thanks. i've been a little confused!

  • @Wyrmnax that was better to understand

  • If the turbocharger is already installed, then how are you "not using it" and therefore achieving better gas mileage? How does the turbo know when to be used for more power, just by hammering down on the gas pedal and increasing your rpm's?

  • @afireinside987 When you're not pushing the engine hard the turbo isn't spooled and thus not making boost. It's essentially idle.

  • my car gets shit mileage with turbo. Mazda cx-7 2007.

  • So this is my question for everyone. Do turbochargers improve efficiency? Do you get the same mpg or more mpg while increasing horsepower?

  • @Emc209i That is true. That is all controlled by the injectors or carb(s), whatever is on the engine.

  • Comment removed

  • @curtis133 very true.

  • @rickster9222 Very good explanation.

  • does turbo work for two-stroke engines?

  • MORON, -____- I don't know how turbo chargers work, I don't know how the exhaust and everything works to cause the rediculous fucking boost. I really don't know how the exhaust gets in at all, I DON"T KNOW ANYTHING ABOUT TURBO CHARGERS, I just know boost is provided by exhaust rather than more air to the piston.

    I can't believe a mechanic (it appears) just basically explained a turbocharger as a supercharger -_-

  • wrong; he explained how a turbo charger works. key difference between turbo and supercharger is that a turbo uses wasted energy, to increase combustion efficiency, whereas a supercharger uses a direct mechanical load placed on the engine to achieve a similar thing.

  • @100percentgiver A turbo charger, as I know a turbocharger, is ran by left over exhaust (that happening in the hotside btw). In the other turbine are is sucked in to be shot through to the pistons, thus giving you a massive boost.

    Superchargers have the well known "parasitic" effect. Running off the crankshaft, they get an instant boost, but power is seeped, but they actually don't get as hot as turbos.

    You're the only one I see on this page understanding his description.

  • @LySeRgIa2 nothing you have said rebutts what i posted. His description is adequate considering hes obviously not an engineer.

  • @LySeRgIa2 the boost comes from increasing combustion efficiency. this is done by driving excess air into the cylinder to aerate the fuel better. If you can also compress the air you get more work done by that cycle due. what both a supercharger and turbo do is achieve this, but with different ways of generating the work required to compress the air. A turbo uses the hot exhaust gasses (basically otherwise wasted energy) to power a turbine, and a supercharger uses the crankshaft

  • UMM im only 15 but i think a turbo is hooked up from the exhaust, when the exhaust blows threw the turbo it spins it wich pushes air threw the carburator sucking more gas and air into the pistons wich is how that works.

    Now dont hate im only 15

    

  • @SuperBmxbadass Most cars nowadays have fuel injection. You're right about the exhaust spinning the fan and compressing more air into each cylinder though.

    PS: I'm 14

  • @XHyperxNovaX ahahh these old bastards thinking there smart lol

  • @SuperBmxbadass The mechanic knows what he's talking about.

  • How can you atomise air? It's already a gas.

  • Comment removed

  • @kalijasin compressing air doesn't atomise it. Air is already a gas, therefore cannot be atomised.

  • @wks1978 atomize: to reduce to fine particles or spray.

  • Comment removed

  • Comment removed

  • @wks1978 Gases can be atomized by being compressed. Ever seen, for example, how gas comes out on the other end of an injector? it comes out as a spray.

  • @kalijasin OK, I get you now.

  • WHAT!?!?!? ITS ALWAYS SPINNING?! I TOUGHT IT ONLY TURNS ON WHEN YOU PUSH A BUTTON IN YOUR GEARSTICK AND IMMEDIATELY MAKES YOU GO TWICE AS FASTER!!!

  • @Towel1e thats nitrous

  • It takes more than 2 minutes to explain the workings of a turbocharger. I would expect a better, longer video from HowStuffWorks. So much is missing: components; how it works and what it does, benefits, drawbacks, comparison with a supercharger, etc...

    As for the guy, who knows? He may be a good mechanic, but this kind of video is more the realm of a mechanic teacher - somebody who is used to clearly and logically explaining and demonstrating this kind of thing to students.

  • anyone else hear the air coming out of the shrader valve stem at 1:40

  • Fuck electric cars.

  • this guy looks like someone who owns a ricer LOL

  • I wonder how long the engines will last with a tubro installed by this guy! he doesnt seem to know whats what! .

  • @GregoryHouseMD1 what are you talking about? everything he said is correct...

  • Sir, your claim at the end of this video is False. Without air the motor would not be running XD.

  • @xXNukeMeXx when he says "fuel" i believe he is referring to the mixture of oxygen and petrol... not just petrol

  • @xXNukeMeXx well the turbo is going to be constantly pumping more air in the more the car works so I dont think he is worried about that... he has to worry about having enough fuel to compensate for the air being forced in... lol

  • people always look down on mechanics but they know a fuck load of things compared to people who work in offices everyday...

  • @shobin05 Coming from someone who works in an office everyday, I have so much respect for mechanics. Its actually my dream to get out of the corporate slavery rat race and open my own customization shop.

  • @franchize31x good luck :D

  • @shobin05 Thus the reason they're a mechanic and the person in the office is a broker? They specialize differently.

  • @shobin05 And people who work in offices every day know a fuck load of things compared to the mechanics. The knowledge is different, everything is determined by the value of that knowledge.

  • @shobin05 i hate that...im gonna be a mechanic when i grow up and im gonna go to lincoln tech next year (senior in high school) and when i tell people their like, why dont you use ur brain or, you to dumb to be a doctor....i hate those people

  • @ODST172 prove them wrong then..

  • @shobin05 i will!

  • @shobin05 The same can be said on people looking down on machinists while they're ignorant of the fact that machinists specializes in using machine tools w/c are the only machines that can reproduce themselves directly and indirectly and can be used to make heavy engineering machineries w/c are used to make machine building machineries w/c in turn are used to make factories that manufactures everything they use in everyday life. Unfortunate that ignorance is predominant in most people!

  • @shobin05 shut up you stupid mechanic grease monkey

  • @stugats77 this guy looks like real asshole thumbs up if you agree

  • @stugats77 lmao, what is your problem? all i said was mechanics are also smart, why are you feeling so offended?

    is it because your so dumb you dont know how to unscrew a light bulb? Or did a mechanic raped your boyfriend? Afraid, thats not my problem,

    And you just replied yourself,

    "@stutgats77 this guy looks like a real asshole thumbs up if you agree", and dont worry i did gave that comment a thumbs up hahaha

  • I can't come on to this site anymore and not see fuckin idiots bagging the makers of the videos. sigh

  • i wouldn't let this dude anywhere near my car..

  • can i use a turbo charger on a weed wacker? answer plz

  • @BlueDragon1212 true that. Superchargers are safer too.

  • I reckon he's referring to superchargers while talking about air atomizing and increasing efficiency. I know that a supercharger leeches power from the engine.

    basically, both systems aim to "charge" the air, increase pressure through forced induction for efficient combustion. Superchargers are coupled to the crankshaft, whereas the turbocharger converts kinetic and heat energy from exhaust gases to run the impeller or compressor. Turbos cause greater psi increase than superchargers.

  • @PushkarChintaluri may they produce less pressure, but unlike a turbo, a supercharger give you power almost as soon as you step on the gas as a result of being belt driven, Where as a turbo has to wait for the exhaust gases to come out.

  • most is bullshit ....atomizing air for example .....no words about some drawbacks , and inernal heat problems , especially about the sock combustion and knocking ....this guy dont understand how turbo´s work ...he just can install them

  • 1:40

    Takes all four cylinders exhaust into one... AREA!!!1

  • THIS GUYS ABOUT AN IDIOT!!

  • When you install a turbo, does you engine drop more gas into the cylinder since you are putting more air in? Someone said its called the stoichmetric ratio or somthing. Also I hear these turbos destroy you engine life by producing excessive heat and putting too much pressure on the cylinder

  • @TheXboxlover45

    Called an intercooler bro, look it up.

  • What a shit of exhaust collector on that S2K!

  • Please remove this video, it is completely wrong he is mixing up external Wastegates and Blow Off Valves.

  • turbo is great deal for cars , but u need to know which the turbo u r can handle it and a better computer program to utilize as much power can get without engine damage

  • PLEASE PLEASE PLEASE do not listen to this video! It is completely wrong. A turbocharger actually works this way: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

  • @wheewheo thats a supercharger... this guy knows what hes talking about

  • Comment removed

  • @wheewheo thats a turbo. this is a turbo charger.

  • @wheewheo Then? What happens when those gases have come into the admission manifold? The pressurized air that is about to get into the block is air from the outside, or its somewhat like a reciclation of the exhaust gases?

  • @wheewheo the exhaust spins a fan and what blows air back in to the compustion chamber what gives the car more boost

  • @wheewheo did you even watch the video, before giving your ignorant comment..

  • @wheewheo

    Right he's actually talking about super Charger :))LOL

  • @wheewheo hello fellow Top Gear fan =p

  • @wheewheo the video said that...

  • @wheewheo LMAO

  • atomizing the air eh?

  • yea save gas.....go luck on smogging

  • haha i told my dad "hey turbo charger gives cars boost to go faster" he says"waste of gas then" then i say "buh wit the boost off it will increase miles" hes looks at me like im crazy and says "i shall consider then"

  • Atomizing the air ? Please explain ...

  • @doldei the turbo is forcing and compressing (making it smaller to fit) the air inside the cylinder to be mix with the gas, therefore 'cause'n my 1988 Conqest tsi with the new 19c turbo to haul ass.

  • @MrFilmMakerNumber2 Do you realy think that there's something happening with the atoms of anything, any changes ? Lol , and making it "smaller to fit" actually has more to do with temperature , but hey , who am I to say anything !?

  • 4cylinder turbo ftw!!!!!!!!!!!!

    FUCK v8s and there cubic inches lolololol

    we got forced induction

  • Atomizing the air?

    Yeah. And it works wonders for your headlight fluid too!

  • TWIN TURBO SUPRA MKIV!!!!!

  • TURBO RX8!!!!!

  • @T3RMN8R are we just shouting "turbo" followed by a car model? cool bro.

  • @onkai It will enchance fuel efficency but it will cost more than fuel will cost.

  • lol 4 cylinders

  • TURBO CARAVAN FTW!

  • thanks been wanting to know that for a minute now!

  • the turbocharger uses the exhaust gas to work while a supercharger uses the engines power itself. the car runs by taking in air/fuel mixture into its cylinders and then ignites which expands the air and creats energy that is turned into motion. but you cant just inject more fuel into the cylinder without more air being injected aswell. so turbocharger basicaly takes the air condenses it and injects it into the cylinders so now you can have more air aswell as more gas. more gas = more energy

  • oi

    so what does a supercharger do then?

    turbos are tiny and superchargers sit ont he intake?

    do they do the same thing?

    the end

    :p

  • the turbo is driven by the exaust gasses which also spin a connected turbine for the intake

  • I STILL DON'T KNOW WHAT IT IS

  • @nonobaOMGWEEGEE2 Think of a turbo as 2 'fans' connected by a shaft. The exhaust blows on one 'fan' turning it VERY fast. The other 'fan' then blows fresh air into the engine under a pressure which is determined by the wastegate.

  • what drives the turbine for the turbo? & why are engines turbocharged? can anyone please answer, thx in advance.... :)

  • @cescagag002 A belt and because you can get more power+ speed out of a charged engine than a normal aspirated engine.

  • @MB007Mustangfan what belt?

  • 1 An engine and a motor are two different things

    2 The only limit to power is not how much fuel you can introduce into the engine. Excessively rich mixutres will reduce HP/TQ

    3 The exhaust manifold looked like an exhaust header to me

  • @pureluck30 Completely agree with pure luck, and also a turbo does not use the exhaust gases produced my an engine it actually uses the heat (why its best to most as close to the cylinder head as possible) and it actually compacts air together allowing more air into the cylinder creating a great air fuel mixture, this guy isnt really that smart

  • @Banakala1991 Not being an ass but you are terribly incorrect. The exhaust gas spins the turbine from one side and expels the exhaust gases through the exhaust pipe while the other side of the turbine is pumping fresh air into the intake manifold and then into the engine.

  • So do cars with turbo chargers in them not have an exaust pipe out the back? or is it just right on the turbo itself? somone explain

  • @TheAandWProductions essentially the exhaust just bolts up to the turbo charger. just look at it as a turbo in between your manifold and the remainder of the exhaust system.

  • @TheAandWProductions I believe its against the law not to have a muffler and tale pipe.

  • logic flows thru this guy

  • finally a person that knows about this stuff...people like him needed more out here in the world!

  • wish he was my mechanic.

  • @paintballgundown8 I'm assuming that we are now bestest friends.

  • all you people spending thousands for faster cars are in the dark. I went to sears and bought myself 2 leafblowers for 60 bucks each. I cut a 2 holes in my hood. put the blower motors outside and ran the blow tubes to my intake pipe. no lag cause they are always spinning and the butt dyno reads at least 30hp gain. torque has similar gains

  • @paintballgundown8 I'm assuming Mexican... Or troll.

  • @Conley800m im assuming someone without a sense of humor

  • He did a good job but he just said what it does not how it works. The motion of the exhaust spins the fan in the turbo which acts as an air compressor. It compresses the air coming from the air filter and forces it through the radiator where it is cooled. Now keep in mind that colder air can hold more fuel. Thus giving you more power

  • @1tirefryer Almost correct, it does not force air through the radiator. It forces air through an intercooler that is either routed through the front or top of the engine to the throttle body. Radiators job is to keep the engine cool by cycling water through the engine.

  • @wasthatfun Yes you are right. I realized this after i commented and thank you for correcting me.

  • Hello, this is the guy on the video. I have been reading comments and need to correct a few things. As far as what it takes to make power. The more fuel you can burn in a engine, the more power you will make. However, you have to have the air to burn the fuel, so that's why your limited to how much fuel you can burn as to how much power you can make. Air can be atomized when swirled around by lets say, a turbo. Seperates the molecules allowing for a more complete burn, like a fuel injector.

  • @RHDMKIII

    Just for clarification...the word "atomized" refers to being comprised of free atoms. A solid or liquid have the ability to be atomized. Any gas or vapor is inherently atomized. In other words, the turbo does not atomize the air to improve fuel economy. It simply creates the same power of an equivalent NA motor at a lower rpm. This

  • Doesnt mention that when your car uses a turbocharger you have to fill up ur gas tank w/high-octane gas instead of regular to avoid knocking. So that costs money! Fuel-efficient yes. Cost-effective no.

  • who gives a shit who knows shit

  • RICERS where the diesel turbo charged

  • I don't give a shit how much I can save with Progressive....I just want to see the video and not a ad

  • guy doesnt know shit lol

  • @Jay200612 you dont know shit

  • a churpacharger is a compressor...hahaha

  • turbo enchance fuel efficency!! Better to tell our parents to get a turbo car!

  • @onkai i heard using a turbo also needs more fuel to have a well balanced combustion. is this true?

  • @onkai i just told my dad , lol

  • Comment removed

  • want to turbo my g6? xD

  • youtube.com/watch?v=JJ2U1GeLzS­8&feature=related

    something that actually makes sense...unlike "atomizing air"

  • Atomize the air?

  • @justduck1313

    yeh dude, the new models contain a small nuke plant which creates tinny atomic bombs that in turn atomize the air. Good thing 56 thumbs up think he "knows his shit".

  • @justduck1313 lol, I guess he meant fuel.

  • 0:55 i just want to let you know that your phone went off. you're welcome

  • this is like relearning the parts of a CPU

  • this is what they learn while crossing the border

  • @PivotPokey wow dude you must be really ignorant not to notice hes not latino.... mahdavi not gonzales idiot

  • @PivotPokey Ass.

  • @PivotPokey guys this was a joke and i am sry to every one who took this the wrong way

  • it's called an engine, not motor.

  • is there a extended version of the video?

  • LMAO at V8s

  • @flamingaxe791 V8s can have turbos too smart one.

  • uh yeah...you cant atomize one substance. you can atomize the fuel in the air, but a turbo wont help with that at all. and a turbo will lower your mileage, because youre generally gonna need to lower compression

  • @pepene93 boost control?

  • @muzacmitchell ...what?

  • @pepene93 im sayin u can have boost control

  • @muzacmitchell sure you can. but you still have the lower compression, and more complicated (aka restrictive) exhaust system.

  • U see all hondas in this video!! Crx, Ek, Eg, S2k. xD Hondas All DAYYY!

  • I had a 95 Saab 2.0T, worst but best turbo car I ever owned. It took what seemed like hours for the boost to build, but when it finally did, the surge was great. I used a manual boost controller at first, then replaced it with a better system from Abbott racing. 18Psi out of the stock turbo, but absolutely awful turbo lag. I much prefer twin turbo's, smaller, spin up quicker.

  • mexican

  • can you hook up your waste gate to the exhaust pipe 1;53 to 1;56

  • NO thats not how they work!

  • turbo is wonderful 

  • The lugs on my wheels take more torque then any shitty honda can produce. Nuff said.

  • TURBO S2000!!!!

  • @JSFER2 gay

    

  • @samanferrari a 2 liter engine that can make 250+ power N/A can make insane amounts when turbo'd. Gay?

  • @JSFER2 ya i can respect that...but the s2000's design is just not my thing
