Runaway Diesel Engines 2022 

Lol ha ha

😄😄😄

diesel runaway occurs because the hydrocarbons enter again into the combustion chamber, so the engine seems to get 2 times fuel supply

@@sajanzunnurain88 way to ruin a good joke Dr. Serious. I'm sure that the vast majority of people who liked this probably understand how it works.

*temper

I did this using a drip pan to an M1120 LHS.

NTC is nothing more than a desert where we took helicopters to crash them. With diesel runaway I always figured my t-shirt jammed into the intake would work. Also thought a fuel shut off valve would work. I never thought about the turbo leaking oil. That kinda kills the fuel shut off idea. Fuel, Spark (glow plug) and air keep an engine running as we all know. Looks like chopping air is the ticket. I know turbine engines better than diesel's but I get the idea behind them. Irwin more like sweating. Been there three times winter, spring and summer rotations. Winter is brutal cold at night like my hometown Tucson. Guys who never been in the desert didn't believe me. After that rotation they believed me. Summer rotation I told my guys to use the whole salt pack from their MRE's. Didn't believe me and watching ten soldiers going through muscle cramps was worth it. Do you believe me now? Lesson learned in our AAR. Listen to the guy that grew up in the desert. He might know things about living in the desert. Fucking do pushups till I get cramps.

​​@@DobermansRockhe glow plugs are just for starting in cold weather. A diesel ignites it's fuel by compression. When you compress a gas it gets hotter as it's compressed. In a diesel engine, clean air is compressed until 400°C. Then fuel is injected into that hot compressed air...and ignites on impact. The glow plugs is to heat the fuel if it's cold (because the cold fuel lowers the compression temperature more than usual). Once the engin is warmer, it doesn't need the glow plugs anymore. My father's 78 merc ran perfectly fine with no glow plugs whatsoever (except cold mornings). When a runaway happens due to an oil leak, or injector malfunction, the only option is to smother the engine.

Easy way is a co2 fire extinguisher in the intake Replace that oxygen

Carry a wood plank in your car or truck for this purpose.

Piece of wood or metal not a phone boom

@@driftingbrandonc.6480 As far as i know, no that won't work.

@@driftingbrandonc.6480 No, read the given text in the video

The truck was a total, at the least he could salvage the battery !

@@mattns13 The way he started explaining it as if he knew something too.

He was trying to make sure the spark plugs were inoperable.

@@Hakken1 which is why everyone is making fun of him. It’s a diesel

With its wide eye staring at us. :(

Thats a scraper

I agree to a point. It is possible that engine was already past it and was given a final send off. Could have had a replacement to go in. But I dunno the background of that clip so just a thought

Im sure Detroit sells all the replacement parts to repair that engine if need be. Two stroke diesels are still in service. Just not as commonly in semis. Youll see them in boats, generators, and even some fire trucks (airport/street use)

Sounded like a Detroit on normal work RPM. ;)

When I was young, my dad told me about it while replacing his turbo (I guess he was nervous about the seals sealing properly, etc and an oil leak). He told me, the only way to stop it, it's to block the intake. And then it started to run away lol, after running a while. He ripped off the intake pipe and blocked it with a plank.

Your English is complicated

People love exceed engine oil level. Also old turbos can cause it. I prefer check this level regularly.

​@@nsx001 nuh uh

​@@nsx001you spoke too soon

It was aimed more at the tyre ? :)

By far the funniest one 🤣

They were aiming for the fuel tank for some reason

Extinguisher into the intake would of worked fine

They should have aimed for the intake, could have worked

yeah, also i wonder why manufactories doesn't install some manual intake blocker in case of this

@@CheckEngine69 my nephew had a mk6 Jetta diesel that did in fact have one. So some do.

At the very least have an CO2 extinguisher in the trunk

@@4BillC I think all modern Diesels now have a kill switch for this , once key is removed it closes the air intake valve

@@markchriestenson3257 Sure, then alll you have to do is recognise the runaway, pop the trunk, pop the hood, remove the airfilter, stick the nozzle of the extinguisher in it and let loose. Aer you seeing the problem here? It's probablhy more dangerous to drive with a high-pressure gas cylinder in the trunk than to accept the loss of your engine in the *extremely rare* occasion that a diesel can runaway. properly maintained diesels don't runaway so just don't cheap-out on maintenance and you'll be fine.

he should remove the spark plugs aswell xD

But it is running off the backup auxiliary unit, so if you cut the power it will stop, he says.

That is a very effective way of destroying the drivetrain. Put it in direct drive and hope that the clitch can handle the extra power. One drriver did what you said and it led to a broken differential, two broken driveshafts on the second driven a le and a destroyed clutch.

best way is to put it into highest gear, e brake on and then stall that shit by getting off the clutch fast.

I knew someone that drove a Mack truck and trailer, he stopped at the lights in south Auckland approximately 25 plus years ago and the engine started revving higher ,it couldn't be taken back to idle, they tried stalling it as well as their companies mechanic tried various things to shut it down, they just had to wait for it to wreck itself, it turned out they go a free replacement engine because of a fault

Why 1st Gear.. to stall an Engine in aTruck or Car select a High Gear and let out the cluch, by selcecting a low gear you are introducing to torue the the transmision..yep something will break or he vehicle will jump forward. Keep other foot firmly on brake pedal !! Easy...

He did! He did! He did!

Maybe he thought it was a hybrid engine-clutch-gearbox-rear axle drive type of vehicle.....or he could just be a j**k

@NÄFYUS 2049 Or wait until it burned all the engine oil 🤣🤣🤣

Yeah dude I’m a diesel mechanic this shit is funny they have no clue lol

Ah yes, the old electrical backup auxiliary unit trick.

Yeah, just a tad! BAAAHAHAHAHAHAHAAAA!!!! I hear the Voyager space craft caught a picture of the piston flying by outside of the solar system?

@@Theresistance64 yea after the Voyager probe took that Earth's photograph, the second most magnificent photograph it took of was that very piston that already reached interstellar space moving close to speed of light 😂😂

🤣

What is yeeted

@@nowthatsfunny1 to throw away at great speed😄

Dude these old engines wont fall apart by any means :D Worst case scenario is piston destruction.

Can’t beat them. They will still run until The last days.

I was wondering how he can balance with such huge balls too

Probably didn't fix it, it seized!

So many people and nobody knew to block the intake. But they removed the battery.

I think they could do it for the first two seconds, then the gearbox would have died and possibly take the driver too

My thoughts exactly! Mite aswell go out in a blaze of glory 😜

Freeeeeeedoooooombooom

Or jump the grand canyon

If the clutch doesnt slip lmao

Always Land Rovers

these damn rovers man, great on the outside but not under the bonnet

"A new head gasket was fitted, the turbo replaced and the engine ran fine again." Are you for real? It overrevved until the sump was dry and you're telling me that the pistons, piston-rings and bore was fine? No way! I'm even worried for the crank and rod journals at that point. There's just no way unless it stopped before all the oil was gone.

Why didn’t you put it in gear and press the breaks to stop it?

@@quirinm. Lets be charitable and assume it was an automatic. The clutch could also be an issue.

Try it on a good old truck, he will show you what he's thinking about that

Too funny! I had the exact same car a 78 diesel rabbit! It would runaway going down a hill and all you had to was apply breaks or find a hill to go up. NEVER pull over and stop or it would run until the engine oil was depleted. It scared the crap out of me the first time but after awhile it was entertaining.

Think after the first couple of times, i'd have just let that vent off into the atmosphere.

Just sold my 1981 diesel Rabbit pickup, I miss it. Even though it was barely driveable

@@joekoncovy ..and you named it 'joek-wagon'??

@@joekoncovy did you break your brakes doing that

Ramming it up the tail pipe... 🙄

And dry chem to boot.

more to the point, he used the wrong kind of fire extinghuiser, that one is unlikly to realy stop the runaway, and will actualy damage the internals eaven more

@@crazy031089 That thing was shot already, and would need a rebuild after a massive over-rev like that either way. They just wanted it stopped.

The exhaust was red hot and caught fire. He was putting out the fire. Not a difficult thing to figure out.

Well honestly, when I was researching some stuff on a particular type of bus that I was basing a sim-rig on, I came across a button on the dashboard that the manual of those buses mentions as: "Cease ignition. Switches of the electrical circuits to stop fuel pumps and cylinder ignition." I am not well versed in engine technology at all, but I was looking at that like "Wait what, it's a diesel? How can a diesel have active ignition?" While this might have been a mistake or an attempt at discussing the function of this button to less technically skilled drivers, and it was a bus designed at the end of the 80's, I can see how that might confuse people. (Also, I know that in some countries the battery can be expensive, and next to that, preventing that thing from leaking due to the heat of the engine should it catch fire while on it's way to self-destruction, might also be the idea there. Having another chemical fire on your hands due to a ruptured battery next to a fuel fire from a car should something go wrong there might also be something they tried to avoid).

Id remove a spark plug

They re dumb af lmao 😂😂😂😂

no, removing the glow plug

​@@SawyerDickeyWouldn't do anything. Glow plugs are for starting up.

You can lose or severely damage your hand doing that, the intake pressure is incredibly high on a runaway engine.

​@@benedictearlson9044 maximum it could possibly be is 14.7psi. Engines don't "suck air in", the atmosphere pushes air into the space where the piston used to be, and it can only push at atmospheric pressure.

​@@tissuepaper9962 We are talking about a runaway engine - which may be behaving in an unpredictable manner. I've heard the pressure at the air intake can be excessive in these situations especially with a truck engine, but by all means prove that wrong by sticking your hand over the inlet to try to stop a runaway engine and let us know how it goes.

@@benedictearlson9044 it has nothing to do with the engine or what it's doing. the atmosphere literally cannot push any harder than 15psi, that's why vacuum chambers are so much safer than other types of pressure vessels. You can't physically generate any more of a pressure difference than that with a vacuum pump. This shit is taught in middle school, I *guarantee* that you learned this when you were taught what barometric pressure is.

@@tissuepaper9962cutting the oxygen off with your hand will shred your hand that guy is right don’t know if you’ve seen someone stick a shirt or something in there to stop it but it’s very dangerous

It was a powder entinguisher an no co2 one. So it would do more harm in the intake than it would help. Also there was probably a fire under the car because of the hot exhaust that burned through like everything?

That doesn't make them idiots. They just don't know.

For a we know this might not happen often

@@-fuk57 Well, that's because they don't choose to learn how it works. I chose to learn how all my stuff works before i bought it. My car, my desktop computer(I do knowhow to program), Dj mixing platform and i even know general construction to repair my home. What do we call people that choose not to learn? There's a word in the English vocabulary for that...

@@DJBillionator Your heart is in the right place but your head is....

all they had to do is shut the fuel off

@@lucifermorningstar1274 I don’t think you understand how diesel runaway happens

You're certainly right about the air shut-off. Many (many!!) years ago my 1st truck was a '72 KW with a 318 Detroit V8. I ran coast to coast for a couple of years when I first started out. I had a blown head gasket replaced in Bismarck, North Dakota. When I got back to Milwaukee a few days later, I stopped in a truck wash to clean the truck before going back to my shop. I pulled up a slight slope to get into the wash bay and shut down the truck. Pulling up that slope and immediately shutting off the engine left a rich charge in the intake. When the truck was ready, I started the engine and it ran away almost immediately. The normal RPM limit was between 2100 & 2300 RPM, depending upon who you talked to. That Detroit ran straight up to 3400 RPM while I was yanking on the air shut-off handle... it came off in my hand!!! The engine quickly stopped on its own when a cam follower failed and locked up the engine. After a quick inspection under the cab we found that the steel wire that ran to the butterfly on the 671 Blower intake was never reconnected by the shop mechanic. After spending a week waiting in Bismarck for the head gasket work, I was shut down for another two weeks getting the new problem fixed. When I started driving that KW, I had no experience with that engine. The engine may have reached 3400 RPM but I'm fairly certain my heart was running a whole lot harder than that for a few seconds before the engine seized!!!!

It's interesting that some modern designs of petrol (gasoline) engine, without traditional throttle butterfly, have an emergency intake flap as backup

@@lucifermorningstar1274 Do some reading. Please.

And the guy who sold it and told you to put that AFT in the crankcase is probably laughing as hard as I am (^_^)

let me know how that goes

1.3M miles without a rebuild?

Glad it worked out for you, but yeah, ether and diesels are a potentially bad combo. A one second squirt is about the max. I had an old Farmall 504 in Buffalo New York and unless the block heater was plugged in overnight it would not even think about starting. I also learned about overdoing ether trying to start that tank!!! I learned real fast you only squirt when the engine was cranking and only for about a quarter second. If it didn't catch, WAIT! That engine had glow plugs. Newer ones have an intake heater grid, definitely do not use ether on them! Lessons learned!

@@Jimster481 big engines can still run even when they are fucked up badly

@@Jimster481 yes. Head gaskets and studs at 510k. Transmission rebuilt at 1.2 million. Been thru a few sets of injectors. Stock power levels.

I know what I'm looking up now!!!! Thanks!

Аккум достали чтоб перезаряда не было.😂

Вони тупі як дошка, я би їм права не дав.

Согласен. Ездить научились, а принцип работы дизеля не знают. Раньше в кабине у опытных трактористов и камазистов всегда шапка ушанка старая валялась. Когда дизель уходил в разнос, толкали эту шапку в воздухан и глушили двигатель.

Додумались огнетушителем под днище поливать! Надо было в глушитель дунуть)

that's why guy is delivery man. If he knew something he wouldn't be doing that job.

Wouldn't the fuel pump stop working if they took out the battery?

@@graygrey4191 it will. but when diesel engine runs away it start combusting it's own oil in crankcase, so no fuel or electricity is needed. Only person can do is block intake until engine stops to starve it from air, because engine will run and burn it's own oil until all is gone and it seizes up

@@graygrey4191 no, the fuel isnt whats keeping it running once it runs away, the oil in itself is enough to fuel it under compression.

@@graygrey4191 no, the fuel isnt whats fueling the diesel at this point, something broke (piston) probably, and its fueling itself with its oil

the probability of these runaways are very very very little unless you barely take care of the motor or you just struck a big bad luck, this is highly unlikely to happen

@Sphered was fairly common on old Detroit with solid injector racks. If they sat for a while an injector would sometimes stick and hold all of them to wot

Clean diesel power.

@@Spheredalai also can be common on a perfectly maintained engines, for example an unaware operator hitting a gas line with an excavator and the gas causing a run away because it’s being pulled through the intake manifold even after the fuel is cut from the machine. It can happen to any one of them and well not super common it does happen besides that fact

Besser als jedes e Auto.

Iv'e seen the reverse run close up.. Little Petter engine with a detachable starter handle. Turning it over on the handle and it kicked back then ran backwards. The handle stayed in place, kept there against the 'one way' pawl. No one dared go near it for fear of the handle letting go. The end came with a classic NNNNNEEEEEEEOOOoooooowwww!! Silence and smoke.

I worked on an old diesel ship, Cooper Bessemer engine, and it had Two sets of cams on the camshaft but no reverse in the gears. To reverse you would stop the engine , shift the cams and restart. I shift incorrectly one time and the exhaust came our the air filter! All large ships that have slow speed engines still do this but with automation not an operator like I was. Oh some large ships have controllable pitch props so the can always just turn in one direction, they reverse by changing pitch

@@josephpadula2283 I don't know if you have ever seen the cam drive on a Harley Sportster but each cam is on its own gear, and they are all spun off a gear on the crank. I put different cams in my first Sportster and being a noob managed to get the crank 180 degrees out from everything else. Tried to start it but knew something was wrong when gas came spraying out of the carb throat. Whoops! No harm done but had to take it apart again to get the timing right.

Yeah that I just laughed at. I didn't even know what I was watching. Like "Oh, there is smoke. There must be fire here!" hahaha

I now know why...

Yeah this shit is retarted. Someone could use that motor or those parts.

They did stop it by plugging the intake with a rag,didn't they?

Well why didn’t you buy it since it such a shame 🤷🏽‍♂️

Sounds like either a 4-53 or 71

Or put in last gear while pressing brakes....

@@groovechampion1462 do that in a big engine and say goodbye to your existence

Wait - the other end of the spectrum is block the exhaust though right ? I dont know much about diesel motors besides glowplugs vs sparkplugs like literally that's all I know, also I heard running out of gas is catastrophic but I would think runni g out of air or spark would be just as bad

@@DuctTapedGoat You wouldn't be able to hold anything over the exhaust tight enough to snuff it out. There will be a SHIT TON of pressure coming out the exhaust pipe. WAY more than a human could hold.

@@davelowets hot as hell too, you'll fry your hands to the bone

They have this on diesel powered pull tractors as well. If the tractor gets squirrelly the man on the sled can pull a lever and it will close the intake on the tractor.

Yes, greetings 😀.

are those different than 'american' oil fields??

@@tommurphy4307 yes, better and we know how to not be cunts to people unless it's called for ;)

@@tommurphy4307 I'm not sure. Likely is not any different. But I don't make absolute statements about something I'm unsure of. I've never worked the patch out side of Canada so I cannot state that. I don't know what your question or comment goal was, but I'm replying that I don't state things I don't have first hand knowledge of. You very well could be 100% correct. Or are you picking a message board fight of some kind?

So very few people seem to be capable of figuring this one out. The clutch stands a fighting chance if you get it into gear and rolling THEN get on the brakes (it's just holding with static friction instead of trying to handle a high-torque, high-slip condition). And for those people who are worried about the gearbox exploding, put it in direct drive (usually 4th gear?) so there aren't even any gears involved.

good way to grenade the transmission, drive line, rear end and now you have lots of things to replace

In the higher gears I would think that the tranny would stand a chance.. Doubt the clutch would handle it, though.

@@Rubensgardens.Skogsmuseum Something's got to give if you can't cut the air intake. Clutch probably cheaper than a whole trans or block.

Ikr

Given engine runaways being so rare, it's our instinct to treat smoke with a fire extinguisher as there could be fire.

@@angkhoavo8004 Common Sense Prevailes Dang Nabbit

using a powder extinguisher is about as useful as throwing sand in the intake.. 🤷

That wouldn't work unfortunatelly. You need a big time CO2 extinguisher to even do anything. Those powder pieces of shit are good for extinguishing a trash bin after a burning cigarette was thrown into it. But be aware, because even this can be too much to them, especially for the very small ones.

. I wonder if you run a hose from the exhaust (with all that smoke) to the intake would stall it .... Not that there would likely be a hose on hand.

Maybe if we can stop the plugs from glowing that will make the situation better

Maybe if we wobble the disconnected battery? Take the battery out? Maybe if we carry it further from the car? No? Okay run around shouting at eachother then!

Yah. No spark plugs in diesel engine. Lol

nope, better solution would be to empty CO2 fire extinguisher in intake to prevent air going to engine

@@JensSchraeder even if there were plugs an engine can run with no battery off just the alternator

When a diesel runs away, can you turn it back on right away? Or I'm guessing you need to fix the root problem first

No, none of them did. Should have immediately had a fire extinguisher shooting into the intake, and that enging should have been strapped down MUCH better... thats was a terrible job, that fortunately resolved without any injuries...

@@i-love-comountains3850 they did it on purpose for the video clearly

@@HircineDaWolf NO, they did NOT

He knew what he had to do and did it with purpose

Mechanically injected 4 stroke diesels can too. Saw it happen on an old cat engine when the driver accidentally stalled it starting from a dead stop up an incline. The truck rolled backwards before he could push in the clutch or brake and it restarted the engine running backwards. He laughed and said "hey I got 18 speeds for reverse now!" He shut it off and started it back up, apparently no harm done.

Isuzu diesels can do that. A driver came into the shop worried about smoke billowing out the air intake.

Detroit diesels will run backwards I have witnessed this in person

@@batmanlives6456 even my 6.2?

@@oldrustycars 90% of diesels are Isuzu diesels

Yeah... If you have space to drive, just accelerate in a low gear, shift up and break while having it in gear (no clutch pressed) so it will just slow it down to a stop. Breaks are stronger than the engine

Especially when you're in high gear

@@qwertz4035 good point

Tks for letting people know, many hurt and die because seems everyone tells you to pop the clutch !

Don't risk putting your breaks under high torque, leave it in neutral and smother it with a fireblanket.... thats why most trucks have it AND a extinguisher

Yeah, but modern ones can still runaway by using oil from a turbo leak as fuel, and then still not need the battery, as per the VW at the end of the video...

@@vincenzodigrande2070 thankfully anti shutter valves are standard in modern diesels, it acts just like a throttle in a gas engine, cutting off air to the engine if needed.

Thank you for explaining the risk of this happening to older diesel technologies vs the newer tech

Ah the old Distant Early Warning system. Glad we haven't actually used that to detect incoming bombs yet. Thanks for your service!

If you fire an extinguisher into an engine intake it better be CO2 otherwise it's ruined anyway

Pretty sure I used the term "co2" at least twice . . . In fact, a lot of engine strangers are nitrogen or one of the CFCs, not co2. @@SavedbyHim

I drove heavy diesels for a good 15 years and never knew about this. Even knowing it I don't know if I would have the courage to open the hood and try to starve the intake when it's running away.

Gretta thunderberg

Be very careful stuffing anything into the air intake, the pressure will be incredibly high so if your hand gets sucked in you could lose it.

Good man

Nah it's an excuse to completely demolish a hell cat in a roll race

If not in the car. Just rip the airbox out and trow a big rag

@@JohneyLockhart I worked for a company that had an old 70s Cat excavator that ran away. A guy tried to ball up a shirt and choke the engine but he let go and it litteraly sucked the shirt in and blew pieces of it out of the exhaust! lol . Two shirts later and he got it.

that can be dangerous because the transmission might blow up

the vast majority of them have cast-iron bell housings- your shins are protected

I wonder if an alternative would be providing a part that is easily accessible that is shaped to cover the intake? Grab it and put it on.

@@AToolWithTools typically a semi air cleaner is about 18” in diameter and around 2’ long. That’s if they only have one. Some Peterbuilt and Kenworth models have two. The positive air shutoff valve is currently the most effective solution until someone thinks of something better.

Owners manual? Surely you jest, sir! No one reads the manual!

​@@Matthew_Eitzmanyour a cool dude

its very unlikely tho the smartest solution is to have an air intake shut off switch somewhere so if it ever happens the engine just gets chocked. With modern electronics, as the video said, its easily possibly to connect the activation of the shut off to an RPM limit or engine temp limit

diesels have to loose line of sight with their battery to quit running. :)
