Turbos in Diesels usually only need an oil feed for lubrication and cooling as their exhaust temps are lower than Petrol/Gas Turbos who need a coolant feed as well due to higher exhaust temps.
Side note: t is interesting that a TDI (diesel) engine has a throttle body. It serves two purposes, under low load when EGR is most active closing the throttle helps to reduce pressure in manifold and thereby helps the exhaust to push more exhaust gasses into intake manifold. And the other purpose is to help with rappid engine shutdown without shudder vibration. Diesel are known to shake when shutting down,.
That was a good breakdown, I like the snapping removal tool. I also like the part where a little kid’s feet swing in and out of the frame. The turbines are a lot smaller than I imagined. Do you have a large semi truck diesel turbo to breakdown ? Those must be a lot bigger turbines? Would like to see a supercharger breakdown, although those are probably a lot harder to come by. I imagine the exhaust turbine is just replaced with a belt driven pulley and it’s mostly similar the rest of the way.
great video.i have a turbo that is leaking intake pressure down the oil return pipe.i took the return off and put a pipe from it into a bottle of water.i sealed the turbo intake and when add any pressure to the turbo it blows bubbles in the bottle.i can get to about 2 psi and even that drops away quickly to no pressure at all.have you seen this before?.
The variable geometry design has a whole lot of moving parts, in an area that gets really hot. I wonder if the added performance is worth the extra fragility.
You need to floor it weekly to keep them working and burn carbon deposits. If you drive it very delicately variable vanes (1) do not open, as you only use part throttle operation and (2) they get quickly clogged with carbon (EGR has its flaws). So, as long as you use the full rev range and the actuators work regularly, plus you 'give it some' at least every two weeks so you can get rid of the carbon build-up, these turbos tend to work quite reliably. In older cars vacuum lines get brittle, so it's a first thing to check if you lack power.
Kinda surprised a variable speed electric motor is not used to run the turbo. I have various sized snap ring removal tools also. Great tear down and explanation!
@@speedkar99 Understood, Seems a lot of extra "stuff" to use the exhaust gasses. Too, kinda crude in input vs output (lag). Superchargers require horsepower. Electrical motors (torque) & modern control devices just "seem" to me to be more precise for conditions of specific boosted air injection But hey, what do you expect from an electrician. I promote your channel to all the other motor heads & retired old farts like me. You are #1. Thanks Bro.
I have this engine in my Skoda Octavia 08. The turbo leaks oil so they are not that good, my car has over 32 thousand kilometers. Can you explain to us why this happens sometimes? Does the turbo have an age?
Very surprising to see how small those turbines are. I agree with what you said near the end of the video...that you have to work those little engines so hard they really don't get all that much better mileage. I assume that working that hard would shorten the life expectancy of the engine as well.
@@speedkar99It is physics (Carnot efficiency) not politics. Nicolas Léonard Sadi Carnot, 1824, Paris. Due to lower friction and a higher fill grade, the efficiency is higher and emmisions are lower. A jet engine is technically an internal combustion engine made out of a turbocharger, simple said.
Nice. My Škoda has this model engine. Low consumption and high power in demand. But it needs to be pushed regularly to prevent the turbo getting clogged. A mistake the previous owner did and I payed.
@@speedkar99 Exactly! I have VW Passat with 1.9 TDI and it seems that it needs Italian tune up every now and then :D Otherwise it won't reach higher rpm:s near redline and just won't accelerate after certain point :D

I see u used the mrs brush 1st then urs 😂🤣 U are one smart dude! Turbos always overheat/ burn up. I wished I could dismantle a 1.8 prius motor over & over so I knew it inside out. Love ur videos, SO interesting!! Thank u. 👍
Great video as always. How many people are working on your video? Because there was 1 clip thats was some one els for sure or your holiday was that great. Your skin was uhm darker.
Sir I really like your videos. You're clear, quick and to the point. You don't dick around and I like that. Just quick, thorough information like an information video should be.
What i don't understand is A) How does a diesel benefit from a turbo? Don't they normally run lean? Couldn't they just inject more fuel (to a point, eventually they would need more air)? B) Why does a diesel need an intercooler? The main funccion of the intercooler is to prevent knock, but a diesel works by having more compression and heat. Couldn't it just have more pressure to compensate for the less dense air? C) Why does a diesel have a boost limit? It doesn't knock, and if it can't make too much power, isn't it easier to just inject less fuel? (But also, the turbo can be a restriction in the exhaust)
With a Diesel, you can suck/force in as much air as possible, but since it's not mixed with fuel until the top of the compression stroke when diesel is injected (compression ignition), there's no chance for predetonation. Do that with a gas engine and the gas that's already mixed with the air in the compression stroke could detonate before the spark fires (spark ignition). Intercoolers are still needed because anytime air is compressed the temperature is increased, according to the gas law, regardless of the engine type that's driving the turbo.
A) A diesel benefits from a turbo in a few specific ways: 1- They tend to have much higher compression ratios than a gasser. Having pre-compressed air stuffed into the cylinder will further raise the compression and increase combustion efficiency. 2 -Diesel fuel if it were compared to gas would have an extremely high "octane"(meaning harder to ignite), and the higher pressures extract the most energy from the burn. 3- the higher compression and burn pressures increase the engine torque, which compensates for the lower rev range diesel engines have. B) A diesel needs an intercooler for the same reason any turbo engine does: as air is compressed, the temperature rises. As it does, the air will expand some, reducing the overall charge density, and as a result, the amount of oxygen that is stuffed into the cylinder. By cooling the charge air, the maximum density and oxygen content can be stuffed into the cylinder for better performance. C) Boost limits are for two main reasons: 1- The piping joints are often rubber in production vehicles, and have a maximum pressure rating. Exceeding this can blow them apart. 2. The bigger reason is the head bolts. Higher compression results in higher burn pressures, which adds more stretch to the head studs or bolts. If the cylinder pressure goes too high, the head gasket will fail, and the engine has the potential to blow. Hope this answers your questions.
@@thomasmiddlebrooke1012 also diesels have boost limit because there is a limit on how much pressure a turbo can make reliably. If you were to let the turbo make as much boost as it could, it would over-rev, heat up and be exposed to loads that it wasn't designed to run at
Good day from Waterloo. Boy very interesting video Growing up on farm with diesel tractors, makes me always think that turbo on diesel is free hp. It does need more fuel & higher hp. Gas engine to run 14-1 ratio gas = air it needs more gas for extra compress air. Is this right??? Thanks Boy when your son was swinging I 1st thought he was flying right into camera. Thanks good video
The stoichiometric ratio 14:1 is different than the compression ratio and they vary from engine to engine. That was the wife swinging in the background lol
That actuator that controls the turbo vanes has a rubber diaphragm that cracks over time and eventually leaks vacuum, and is a “non serviceable” part from Volkswagen. Boy was that fun to replace in the car on my old 2006 😂 German engineering at its finest. I had to make my own tools to remove most of the hardware for that job
You called the anti-shudder valve a throttle body when diesel engines have no throttle bodies. That valve is to prevent runaways and excessive engine shake when turning off the car.
Dumb question: does a turbo constantly “work” then? Like even while cruising on the highway you are always using you turbo to draw more air? Is that why your gas/mileage drops?
It partially works all the time but the more you accelerate, the more fuel goes in and more thermal mass exits the motor to spin the turbo. Thus the end result is that there might be a partial vacuum in the manifold until you decide to give more gas and the pressure increases due to increased fuel burned. So when cruising the highway, at least usually my Volvo 940 manifold pressure stays negative (usually -0.6 to -0.8 bar) but it is certainly higher than idle manifold pressure (around -1 bar). TLDR: the turbo works a little yes but not as much as when applying more gas (accelerating).
@@speedkar99 I think they call it PICTURE in the Chanel Configuration. Sorry if I am just imagining things ! Would be great to see a basic explanation of the different configuration of Hybrid cars, even if you have not got your hands on those yet. Thanks anyway, you are one of the best out there, no doubt, and I've seen dozens of auto-sites.
Specifically speaking coolant to air type coolers are called intercooler/aftercooler but the Air cooler which use Ram Air are called as charge Air cooler..truely impressed and inspired by your videos🥰 you have immense knowledge astounding 🔥
Most times a turbo dies because of other problems. Lack of lubrication, foreign objects. Sometimes the spare turbo will die too, before the problems are corrected.
Among petabytes of pure garbage your channel is the best I found in about a year. Again, I knew the principle but I've never seen turbocharger disassembled. That's a hell of a knowledge, so I'd like to thank you for doing that and I hope UA-cam pays you a decent money for your work. Just a question though: what's the purpose of this blow-off valve if it sends compressed air back to the inlet of the turbocharger? It seems to be a closed loop, not decreasing overall pressure of the compressed air, so why's that for? I thought that blow-off valve releases excessive air straight to the atmosphere. Could you explain me that? And again, thanks for uploading super interesting content.
Blow off can release to the airbox or the atmosphere. When released to the airbox (at ATM pressure) it just gets recirculated and dampens the sound (that's why on most OEM setups you don't hear the air rushing out) whereas if you release to ATM it'll make the distinctive whistle
@@speedkar99 Now I understand. Recirculating excess air to the airbox dampens the whistling sound while still reducing pressure as the airbox isn't pressurized. Thanks for the explanation!
This guy went back in time when the engine was still in the car and back to continue his explanation
I went back in time taking apart the turbo too, then skipped around explaining the intake part. Filmed it out of order

The variable geometry design has a whole lot of moving parts, in an area that gets really hot. I wonder if the added performance is worth the extra fragility.
Moving parts and heat isn't the issue...lack of lubrication would be
not all variable geometry turbos are good but the ones used in vw engines last a long time

I don't really like the plastic gears inside the throttle body because if they break you get a runaway potentially
The throttle body shouldn't control much in a diesel anyway, but yes everything is moving to plastic, including stronger mechanisms like wiper motors.
They may be made of nylon and that would be strong enough. IMO
