Some Audi race cars are powered by the NEW R10 engine. This engine is now available in new AUDI SUV on a V12 Configuration. TDI Turbo Direct Injection. Trade Mark of Volkswagen
@@playgt326 It ran on synthetic diesel, made using gas to liquid. Could easily be fed from vegetable oil stock, but wasn't due to the relatively low volumes needed for their race program....
Diesel has really evolved over the years. Since the introduction of Turbos, its incredible what you can get out of these engines. Can't wait to see the Subaru Diesel. Bet you will see it in the WRC.
This should be a t.v. commercial representing the TDI as we know of. But we don't hear much of Le Mans in my country, only F1. Greetings from Ireland. :)
The Honda S2000 is my fav car becuase of all the power it produces in a 2.0L engine, The Audi TDi Engine has made me on my favorite list just by listening to the engine purr and how it uses diesel fuel and dominates. Go Audi.
Robert Huber made a prototype in the 60s, and hino used a denso common rail system in 1995... its called the edu-u2 common rail, or something similar to that boshe made the first computerized common rail, but basically just added the ecm and i/o's to the denso system
When VW introduced their TDI engines TDI stood for Turbo Diesel Intercooler, cause they still used swirl-chamers, there for no direct injection. Modern cars uses electronic direct injection and TDi stands for Turbo diesel with Direct Injection. Mercedes 2.5 L OM602.962 Turbo Diesel used mechanic direct injection, but was not an true TDI engine, even though it was a turbo direct injected engine CRDI stands for Comonrail Direct Injection, Ford used Volkswagen 1.9 CRDi engines for example in Galaxy
Entropy should have never entered the discussion. Neither should have "273K" or half of that other stuff. So Duck, you really understand entropy hey? I am glad you are on the job judging the quality of other people's comments.
@nemanume There are certainly indirection diesel engines, which work with a pre-combustion chamber (search on internet). and TDI stands for Turbocharged Direct Injection
That's also due to the high amount of paraffines in diesel fuel. I heard that they often use winter Shell V-power diesel because the lower amount of paraffines have a lower burntime.
My bad experience with the Audi was long ago in the 1970s. The A/C never worked and the valve guides wore out within a few thousand miles. I had them replaced once and they soon leaked oil again. There were other problems too that no one could seem to repair. But that was 30 years ago, and I am sure that Audi is making more reliable cars now because I see a lot of them on the road. If the later model Audis were as unreliable as mine was the manufacturer wouldn't be in business now.
Exactly. The problem of the diesel engine is that it needs more air to increase the rotation frequency. Sequential turbocharging and variable geometry turbocharging can the engine more breath. Both Audi and BMW are experimenting with both technologies.
Yes, you're right. I was mixing things up. Anyway the second law describes the increase of entropy which isn't important in a flowing system. And since high temperature heat can only dissipate towards low temperature heat I can't imagine a 273K intercooler not to work? It might slow down burn time though.
you are correct, pre-ignition is only a concern is petrol engines, because all diesels are direct injection..... by definition. All diesel engines compress the air, which creates the heat, which ignites the fuel that is injected when a petrol engine would be firing a spark plug. Diesel engines are fuel throttled, unlike petrol engines that are air throttled. hence the reason my 6.2L diesel has no carburator or throttle body.
@letmesnitch I thought that TDI was Turbo Diesel Injection but, in Wikipedia I read the meaning of TDI and it's Turbo Direct Injection, refering to da Direct Fuel Injection System used in VW Diesel Engines. Da homologue in Gasoline is da TSI engine
Yeah, I heard about 2 stage injection. Seems it's actually invented a long time ago. Isn't it similar to Alfa's TwinSpark to get have a first light preignition and having the second spark ignite the whole mixture?
You are thinking of -273C. 273K is 0 Celsius. The guy who mentioned 273K is just trying to be fancy and show off. Pre-ignition can occur on any engine that does not have direct injection, Diesel or petrol. Some new petrol engines (Audi and GM and some others) are direct injection so they can run really high compression ratios without worrying about pre-ignition.
Maybe It stands for Turbo Direct Injection for VW/Audi products, but for all other manufacturers it stands for Turbo Diesel Intercooled. Mazda B2500 TDI in South Africa is NOT direct injected. Isuzu 280 DT was direct injected but no intercooler. Isuzu 300 TDI was direct injection WITH an intercooler. Ford Escort TDI was NOT direct Injection, but had an intercooler.
it might be as you say. can't argue as long as i don't have any kind of experience with cars made in US. Anyway more often service and check-up is good for your own safety. You can drive more confidently when you know your car it's as it should be.
why dont they put this engine in the r8 instead of a freaking lambo engine? the r8 is an awesome car, but when it has a lambo power plant, its just a lambo in an audi body, i would love a turbo diesel race engine in an r8, or an r8 all toghether, but its like putting a chevy engine in a ford chassis, either you just dont, or you have some weird frankenstein
Wow, that's pretty scary. I remember reading that when Mercedes went to an electronic braking system, they had an emergency hydraulic override in case it decided to go "windows".
I to am a diesel lover, but bare in mind that if a petrol car was turbo charged at the same pressures the power would be a lot more, until it fell apart/ melted itself etc!
@ttaborda You should also get your bases right! Audi A8 (D2) 3.3 TDI was the first using common rail in the VAG group per say And the EDC common rail was developed by Magneti Marelli for Fiat. As there where not enough cash for continuing development they sold their invention to Bosch group who continued development and then presented it to the world in the Alfa Romeo 156 JTD.
With DiesOtto and CCS/GCS I specifically meant the core ideology Homogeneous Charge Compression Ignition. Except the DaimlerBenz AG concept uses unleaded fuel and Volkswagen Group AG wants sulphur- and arene (aromates) free biomass-to-liquid fuel.
amasing that diesel can make suck a nice saund and the car is awsome tooo sum say that diesel is fuel of the devil some say thet diesel is the fuel of the feuture we will se nice vid
@ttaborda I think TDI stand for Turbo DIesel? I don't have anything to back that up, but that's what I've always thought it meant - what do you think it stands for, since this shouldn't be called TDI?
The Clausius statement which states that heat cannot transfer from a low temperature object to a high temperature object? Anyway, the (sub-)273K intercooler is not an idea. It's simply a quick thought. ;) I still believe in DaimerBenz's DiesOtto and Volkswagen's CCS technology which combine diesel cycle with otto cycle. Do you think this is only possible cause of direct injection and variable compression ratios?
You would get cooling problems and preignition due to the extremely high airpressure. Unless they invent an intercooler which cools way below sub-273K temperatures, but that would result in either engine knocking or no burning process at all. Theoretically, you a diesel engine can easily be tuned much higher thermodynamically then petrol engines. But our technology isn't advanced enough to build an engine that could handle the forces.
Le Mans rule makers have dropped the tank capacity for diesels only ..no rev limits, no other restrictions whatsoever...basically they'll get 2 or 3 laps less advantage over the petrol engined cars this year. The rule makers may have been a little more harsh but for the fact that the French Peugeot \ Citroen company have entered a v12 diesel this year also. The Peugeot seems to be a little louder to me, anyone else heard it yet ??
The second law cosists of Kelvin-Planck and Clausius. Look at the Clausius statement. I suppose an intercooler at 273K would be feasible if you carried around bags of ice. There is no reason for a cooler intake charge to cause slow burn time (desirable in a diesel actually).
SqtH3nry3, pre-ignition in a direct injection diesel like this TDI is not possible. Only air is compressed in a diesel and then the fuel is injected so pre-ignition can't occur. Since you seem to like thermodynamics, I suggest you become familiar with the Second Law of Thermodynamics. You might learn something about your 273K intercooler.
@letmesnitch Making some sense about your comment, I review in other sources and all of them agrees that da meaning of TDi is "Turbo Direct Injection" U_u
So what do you suggest, that american cars dont need to be maintained? cars do need service no mather the make. FSI and TDI are both direct-injection fuel systems. first is for petrol and last applies to diesel. there is also DSG (Direct Shift Gearbox) but this is some other stuff. regards.
Thats my point, a petrol would die. A diesels max bhp is limited by max revs mainly as bhp= torque x rpm divided by constant, so max bhp means little, look at diesel torque figure, these r high. Engine knock is a result of high temp, it is the sound of sonic booms due to flame fronts exceeding the speed of sound. With petrol u can get fuel puddling aswell if temp to low. Big coolers can cause lag aswell.
