Some things to know about turbo charged engines. When the turbine compresses the air for the intake, it also increases its temperature. On a diesel engine they have to run what is called an intercooler because the compressed air is too hot entering the engine on its own. So an intercooler is used to cool the air to increase its density prior to it being ingested into the intake. It is normal to idle the engine, an extra one or two minutes before shutting it down to allow the oil to run through the turbo as it spins down. The turbo does not spin at idle because there is not enough exhaust pressure. Turbos are most efficient at wide-open throttle settings. The difference between a turbo charged engine, and a supercharged engine is a turbo charger runs off the exhaust gases, while the supercharger is mechanically driven off the engine. Another name for a supercharger is usually called a blower.

Turbo charged petrol cars use intercoolers as well. Why is that?

[@lewisd56]

@@rachetsredemption8265 same reason for turbodiesel engines, increase density and hence oxygen content per unit volume, plus cooler air lets the engine run cooler. A turbo wont spin at idle because a bypass valve switches it off by letting the exhaust gases go around it, once there is enough exhaust pressure the valve closes and the turbo is allowed to spin.

[@aviatortrucker6285]

@@rachetsredemption8265 Like I stated before, when air is compressed, the temperature rises and becomes less dense. The more the boost the hotter the air gets. In a gasoline engine this can cause combustion the same way as a diesel engine. You don’t want that you want the ignition timing to ignite the fuel at the proper time with a spark plug. This is why they use an intercooler, which is a device for cooling down the air prior to it being ingested into the intake manifold.

I normally wouldn’t recommend people learn flying knowledge on KZbin but in the case of the channel I make an exception, this is properly explained and well edited. Excellent work

[@jilliandecastro5843]

Very well versed

[@shanehunter9276]

Having just completed your IFR course, I am looking forward to the Commercial course as well; the instructional methods, demeanor, and graphics are spot on! Thanks for all you are doing!

[@adrianjones8073]

Your instrument videos helped me so much, I'm so happy you're starting a commercial class now that I'm working on my commercial. Impeccable timing lol

[@flightinsight9111]

Glad to hear it! We've been hoping of putting this Commercial together for a long time. Now it's only hours away!

[@johnjohn3241]

These videos literally helped me become a better flight instructor. Thank you!

[@brackenquinton2955]

You are such a legend. Such a great straight to the point explanation.

[@aviator3815]

This is such a plain English version of PHAK. Well done, sir! I’m a CFI, and I have my students subscribe to your channel

[@treezy2x31]

Just watched a sporty’s video on this and they made it so confusing. So I came to my ol reliable lol. You’re a national treasure

[@airwalk247]

I love the video, Almost a tutorial in the begining and an OJT example with a Sim half way though, showing a next to real life example. Explaination was well done. Liked and subscribed.

[@cletus2199]

I was thinking about this very same topic today as I was driving home from ground school academics(army rotary wing). Thanks for this explanation!

[@flemmingstelling8079]

Very well explained - good yet simple graphics - thx

[@mikepapahotel]

Excellent explanation! 😊👏🏻👏🏻👏🏻

[@YourFriendlyGApilot]

Super explanation, as always!! Thank you for the great content.

[@masterswitchaviation]

Great explanation!

[@vfx7t]

I love too PA-28R Turbo Arrow III/IV (MSFS) from Just Flight thank you from Algeria ;))

[@AM.Boxing]

Commenting and liking as I promised

[@JustSayN2O]

A friend of mine has a Turbo Commanche single, 1970 I think, which features a manual wastegate control on the throttle quadrant, left of the throttle. Four controls: wastegate, throttle, propeller, mixture. The wastegate control has a tab which mechanically PREVENTS the combination of closed wastegate and closed throttle. More specifically, the throttle control has to be advanced further forward than the wastegate control.

[@swordfishchaser7]

Great videos! Don’t stop!! Make a CFI course!!

[@flightinsight9111]

Thanks! More people requesting this will make us consider it sooner!

[@ritzneo]

Where is the manifold intake pressure in the cockpit at

[@aca20031]

Is manifold pressure meaningfully higher than outside air pressure due to (1) Ram air pressure, the relative speed of the air caused by our airspeed and (2) suction created by the vacuum in the pistons as fuel burns and pistons are pushed uP

[@dennisnbrown]

You should probably address turbo normalized

Needed to hear this 🙌! Get to the top FAST = Promo_SM!
