Tire burnouts are boring. This guy actually burns his whole engine out ;-) Although i don't think he intended to do so. I wonder what would have happened, if the other guy did not incidentally come along to shut the engine down.
This was a turbo diesel model BMW. What happens is the seal in the turbo fails which causes oil to be blown through the intercooler piping into the engine. The oil is combustible and causes the engine to continue to run. This condition is also called a "runaway"
Blocking the air intake is one option, but on the M57 engine the way the pipes and ducting are its difficult, not to mention the angy pissed off noise the engines already making that completely puts you off putting your hand anywhere near it.
I've heard that stuff like this happens when you have old diesel engines. Bits of fuel and oil make flammable, greasy glop which stays in recesses in engine. Then, after a long time this thing can suddenly get to the cylinders and start uncontrolled combustion. That's what I've heard.
This happened to me without a crash, the engine runs aways with itself and self destructs. As a diesel needs no fuel inginiters as such, it just keeps drawing in more fuel even with the ignition off and the keys taken out!
What has happened is that the diesel engine has begun to run on its own oil, so even switching the engine off will not stop it. Whether down to an oil leak internally or over filling with oil. Luckily someone knew how to stop a 'run away" diesel engine
@bonecrime Great observation on that one! Alot of folks out there just dont catch on to these things that quickly! It is good to see we still have some machanically inclined people around!
@denne007 Yes, if the turbo leaky oil attain into engine and it will use the oil as fuel. You can switch of the ignition or pull out the key, engine will run till oil is depleted or engine blows up.
@DYNAMIZER I never knew that was even possible! So not only are you revving your engine to death, but you're draining your oil at the same time? Bad scene, for sure! Do you think that that is how that guy shut it off? By putting it in 5th and popping the clutch? Not that it's anything I have to worry about...they hardly sell diesels in the US. But still interesting to know. Thanks.
@jzy0104 he wasn't burning fuel .. he was burning the engine oil!!! the engine oil is passing in the turbo to lubricate the bearing but if the seal on the intake side is shot, engine oil will enter in the engine and act like diesel, thus igniting. The only thing to do against that is to open the intake and place your shirt or anything blocking incomming air.
To be honest, I laugh at those who says to turn of the engine :D The guy has already turned ignition off, it wont even help if he removes the key.. it's a diesel engine! Diesel engines work on compression, they don't have spark plugs, they have glow plugs. Glow plugs are usually switched off after few minutes from cold start. When the engine is warm it doesn't need them to be heated as heat form engine block is enough to keep engine going. In this case turbo shaft or seals failed.
oil from the blown turbo goes into the intake and combusts, even if you shut the ignition off the engine would theoretically try to run itself, but i guess modern cars do have systems to prevent this (I know my 1.9TDI has smthin just for that case).
@kaimelis dont wanna argue but there is only semi-automatic, which gived you 3 options, auto, auto-sport, and clutchless manual( all u do is change up and down clutch is done for you) trust me i know because i wanted a manual but they dont make em only the steptronic semi auto,
The engine (diesel) experienced a diesel runaway. The trottle sticks but the engine cannot be shut off. It can run with no electrical input, therefore, it just keeps sucking the fuel into mechanical (engine driven) fuel pump. Scary when it happens to you.
@mazda6six read the description and / or just few comments, he has keys in his hands ("off"), and since he has automat, there is no way to stop the engine, till he eats all the oil...
This is why u allways have to check ur turbo. I had this problem once with my 530d automatic. Lucky i had some small kife in my car, so i cut the intercooler pipe and the engine was saved, just me and everything in engine bay was covered in oil. I still driving the car with no problems now
Runaway diesel : only way to stop is is to drop clutch on a manual, or plug the intake with a cloth to choke off the air so it won't combust anymore. Dropping the clutch is better because the choking can cause hydrolock if it puts in much oil. Probably still better than to wait for the big bang because of run-dry big end bearings though.
@ebradahusla the turbo leaked oil on the compressed air side. by the high rpm of the turbo, the oil gets supttered, gets into the engine and because it's an disel engine, the engine runs with the oil of the leaking turbo on it's highest rpm. so you can't stop it by switch it off. the only way is to put it in 5th gear and leave the clutch.. otherwise it will stop when the oil is empty or the engine overheats an gets stuck.
It's caused by leakage of oil from the turbo, so it enters the cylinders and burns. The only way to stop it is engaging the highest gear and slightly releasing the cluth, whilst pressing the brake pedal.
@quatroportte That is not a blown head gasket, it's a failed diesel fuel injection pump. My turbo diesel car did exactly the sanme thing last night, but luckily for me, I have manual transmission, so i was able to stall the engine before any damage was done.
Mialem tak w swoim transicie,moim szybkim pomyslem bylo wbicie najwyzszego biegu i wcisniecie na maksa hamulca tym sposobem udalo sie go zadusic,inaczej motor na zlom a winowajca to pompa wtryskowa pozdrawiam:)
ppl who dont know whats happened to the bmw must read that its a problem at turbo, sometimes when the turbo crash the engine stay puting oil in turbo and cuz the turbo is crashed then the oil go with air and return to the engine and burn with air , and the engine wont stop if u will try stop it by the keys u must put the gear at 5 and stop it like the man did in this video
@DYNAMIZER Thats right, but not necceseraly oil from the turbo, could be any oil from the engine also. If there is a leak/ crack internally in the engine and the oil gets in the silender, too hot and it will "pre ignite". To get it in gear is almost impossible because of high revs. My Nissan truck engine did the same thing.
You have to cut off the air. Nothing burns without air. Throwing a jacket or heavy shirt into the air filter box often works. Easier said than done, though.
@Pitchplus8 ja is leider so da die einfach den ladedruck hochballern ohne die kennfelder anzupassen und dann passiert sowas nunmal unweigerlich früher oder später... besonders die E46 320d VFL (mit 150 PS) haben mit turboplatzern zu kämpfen
Most new diesels have an automatic valve that closes the inlet part and they can just be switched of with the ignition key. The engine gets no more air and it stops.
I know that diesel engines don't have a throttle valve like gasoline engines do. If you read the other guy's comment you will see that I was telling him that modern bmw's don't have a mechanical linkage at the throttle body like older cars do. They have drive by wire throttle.
This is called a runaway. Basically it starts consuming its own oil and running at a very high RPM as a result. He's lucky they could shut it off without shoving a rag in the intake.
Would unhooking the battery really help? Diesels don't have spark ignition. If it goes berserk, it goes berserk... can't do anything until it seizes, blows or burns, unless you stall it with a manual transmission.
Bear in mind that a diesel doesn't have an ignition system. If this indeed was a runaway diesel there's not much one can do, if there is any combustible product getting in the engine it will continue to run. Decades ago I recall watching a American gasoline powered car 'diesel' backwards as is sucked all the unburned fuel in the exhaust system. Anyway, I don't imagine the engine in this BMW is in very good condition at this point.
@XSickBastardzX Actually nowdays diesels are having airflaps that close when turning engine power off. When no air is sucked into cylinder engine stops running even if it had oil running/burning. In this case those flaps are probably removed cause m57 engines are having problems with them. Anyway it's shitty case when engine starts running with oil. :|
@215alessio youre most welcome! if you ever visit youll see its incredible how many different fruits we grow here you had no idea existed, its due to the microweathers we have here, youre at the beach its dry tropical, drive 85 km and be at cloudy tropical, we havce more then 5 different type of tropical types in 54 000 sq km, but only in wet or dry season. Id say you dont have many suv's in italy because you dont need them I was at lago di garda and you have pretty much perfect roads anywhere
ive had this happen to me in a turbo diesel, the turbo oil seals let go and the engine was running on its own oil. even if if u turn the car off at the key it still keeps running, only way i could kill it was put it in 5th gear and stand on the brake as hard as i could to make it stall.
Ein Diesel hat keine Zündung. Das passiert, wenn ein Diesel sein eigenes Motoröl verbrennt. Mit Schaltgetriebe kann man mit Glück noch abwürgen, bei Automatik hat man verloren.
BTW... sorry for my bad English. I'm Dutch. p.s. the other guy in the video try'd to help but believe me... he did nog stop the engine. It died.... Maybe the guy new what was happening but and he try'd to find the clutch but he didn't find it.... (X5 3.0d is automatic) When it happens to you and it's an automatic there is one way to stop the engine.... pul off the intake-hose and block the intake! The engine can't take its air and will stop cause te oil won't burn without air.
With a runaway diesel engine. With the vehicle stopped, set the park brake, hold the foot brake down hard, set transmission in highest gear, let the clutch out to stall the engine. (^_^)
No funciona en este caso ya que es un motor diesel y está quemando el aceite que se filtra de la vena que lubrica al turbo, aparentemente falló la junta que impide el contacto entre el aceite y la admisión.
@mazinais31 That wont help.. The car has a generator = its producing its own electricity. You have to choke the engine, the easiest way would be to take off the airfilter and put a towel in the pipe. - Or disconnect the Fuel/air-mixture meter. Or if u have a manual gb - all u have to do is put it in 5th gear + handbrake and release the clutch.
Wrzucamy 5 bieg i puszczamy sprzęgło-auto gaśnie i po problemie :) Ewentualnie jeśli jest to możliwe zaglądamy pod maskę i ręcznie zamykamy przepustnice przyduszając silnik-i po problemie.... :)
Tylko ze to automat jedynie odciąć wąż od egr i przyłożyć coś płaskiego by zamknąć dolot powietrza bo rękę raczej nie bo czerwono by z tlumnika poleciało
@frankfranke: Schlauberger, da ist sicher außer Dir keiner drauf gekommen. Wenn ein Diesel auf die lustige Idee kommt Öl aus dem Sumpf anzusaugen und zu verbrennen kannst Du so viel Schlüssel abziehen wie Du willst. Der bleibt an. In Kombination mit Automatikgetriebe kannst Du das Ding noch nicht mal abwürgen, sondern nur warten bis das Öl alle ist und der Motor verreckt.
@renesisrx8 yes thats true. New italian cars make it even a step further. Gasoline cars with no trottle, (therefor only diesels had no trottle). For even more fuel efficiency than wired controlled trottles like German gasoline cars
@adminlvieira Stop the car, step on the breaks as hard as you can, put it in highest gear and then dump the clutch. It depends, but it could stall the engine or just slip on the clutch. And it of course won't work if it's automatic. The second option is to try to block the air intake somehow. There's probably more ways, but that's what I can think of atm.
They couldn't stop it, they probably already took the keys out but the engine kept running on oil. And since it was automatic they couldn't release the clutch either in gear. The black smoke is pure oil that's burning.
@Greddybear wont be that, if that was the case, turning the ignition off would stop the engine. it will be running off the sump oil, this can oly happen in a diesel engine, petrol engines dont have enough compression to run on oil
continuing my earlier post.... Engine is using engine oil as a fuel, that's why smoke is so black... Most of you don't know what are you talking about, search here How diesel engine works or something.... petrol engine works differently form diesel engine....
Yep ... smother it (not usually possible), stall it, or shut off the fuel supply (not usually possible in a passenger car). It won't burn only oil, it must have some mix of deisel ... in heavy trucks .. if your are daring enough to get that close ... you can shut the fuel line off. Its my understanding that its hard to get it in any gear with the rpms so high ... ? ...
@Chiuas666 naja, der Lader bekommt auch im kalten Zustand jenach dem beim anfahren seine 200000 Umdrehung ab je nach Größe des Laders. Den Vorzeitigen Tod des Laders machen schlechte Ölqualität durch nicht eingehaltene Wechselintervalle aus, sowie direktes abstellen nach Vollgasprügelei so wie man es z.B. hat wenn man Auf dem Autobahn Rastplatz Pinkeln geht. Generell gilt es den Motor immer etwas nachlaufen zu lassen und nicht direkt abzustellen.
@CaHboKk Это Х5 они в 90% случаев с автоматом покупались. Может и не помочь. Может просто сцепление спалишь. Ее можно вырубить только остановив подачу воздуха в движок но до него еще добратся надо. Это же не камазовский дизель в котором только пара шестеренок крутятся.
runaway diesel. They didn't shut it off, it seized. Really there is no way to stop one. Once is finds its own fuel source (over filled with oil or blown turbo seal) it will just keep going.
@sander2908 maybe automatic. But a high reving 3.0 litre diesel engine you wont stop with releasing clutch in a high gear. U only will kill the clutch too :P
@NightmearSVK , actually you can, at least on some cars. If you can get to the air intake duct or hose & either block it or collapse it will choke the engine & stop it. Although it's not as quick and maybe not be quick enough before it throws a rod, oh yea & it means you've got to go under the bonnet with the engine about to blow up right next to ya!!
