Usually it's due to a bad turbo leaking oil into the intake side. The engine starts running off the oil, which increases the RPMs and in turn sucks in more oil to feed the engine. Only way to stop it really is to block the flow of air, or drop the clutch in a high gear to force the engine to stop running.
I have an SUV with a diesel engine. There's a throttle in my car's intake system, so when I turn off the engine, the throttle stops the air from getting in the intake manifold. Don't modern trucks have a similar system
Every vehicle has some sort of throttle body that opens and closes, even big rigs. Not all diesel vehicles come with something to help prevent or stop a run away engine though. A runaway engine can still suck air in past a throttle body.
I have a lot of commercial diesels. None of them have any sort of throttle body from the factory. Care to show me which engine specifically your speaking of ?
So none of your commercial diesels have a device that controls the amount of air that comes in? Your engine's intake is just 100% open 100% of the time?
This doesn’t look like this is the scenario here but while working in the oil field we had kill switches on a lot of out trucks as there are wells thats produce Methane and when it would go through the air filter it would cause the truck to takeoff.
They explained it. Diesels can basically keep running at high rpms with no way of turning them off. Like you try to turn it off and it just keeps going until it either destroys itself or you can starve it of air
Yes. Also did you know that diesel automatics aren't fully automatic? You can change the gears if the computer isn't changing them properly. You just don't have to worry about synchronizing or a clutch pedal. Don't think you can stall them like this though.
What's in the video is diesel runaway. Which is caused by a damaged turbo leaking oil into the combustion chamber. Once that starts it's a nearly never ending cycle until you burn up the oil, motor explodes or the air is cut off.
Improper maintenance and over stressing your motor. I don't know how common it is in oil fields.
Let's say you get low on antifreeze. Over heat the engine. The heat causes stress cracks on the turbo. You cool the motor and top off antifreeze. Later on you pull a heavy load up a hill warming the engine above 200. Stress cracks get worse and start spitting a few drops of oil into the motor. Motor starts running off of oil. Goes into Can't stop won't stop mode ^(TM).
My driver leader wondered for a while when I ran on i40 in the gorge with a specific shipper I always shut down halfway through for at least 2 hours. Finally told him I didn't want to become a ball of flaming metal. Am I being overly cautious? Maybe. But I'd rather be overtly cautious than a ball of flame.
An old mechanic i worked with told me a story about a runaway he encountered. Tried this (stall on high gear), and the input shaft on the transmission just snaped.
Dropping high gear is worth a try but not a guarantee to work. The best course of action if that fails is to get away from the truck and let it do his thing. Even a 70k engine is less expensive than your life.
Roda-deco is one brand. They are called a positive air shut off device. Any dealership can get them, usually run about $3500-5000. If you get one test it with the vehicle off, then try and start it. They really don’t enjoy being smothered to a stop repeatedly.
There are devices that you can install that do exactly this. I've seen them on diesels at oil refineries. Refineries require them for safety incase their is a flamable gas leak that could also cause an engine runaway.
Dumping the clutch is one way to kill the engine, but another is to just blast a fire extinguisher directly into the air intake. No matter what you do though, there will be thousands of dollars of damage done.
It's not going to matter much what kind you use because after a runaway, even if you stop it quickly, you need a rebuild. Your rotating assembly was not made to hand 5k rpm and it's very unlikely to be okay. Taking off the the whole intake side to clean out the extinguisher chemicals will be part of the teardown for inspection anyways so fuck it spray it
Fun fact, steam engines are actually where the term "rolling coal" comes from. If you had a fireman who couldn't do their job very well, you'd just say that he's rolling coal
Cheaper and easier to use your fire extinguisher. Motor is pretty much toast anyway, so it's going to do a lot less damage than taking out the clutch and bell housing and a drive line. Save the block and rebuild it. Or potentially put a rod through the block or destroy the drivetrain.
I imagine it depends on how quickly you're able to set this up. If you recognize The Runaway situation before it's screaming at 3,000 RPM you have a better chance I think
3k? I watched a red top Cummins run away and driver just freaked out. I ran over and threw my coat over the air intake to kill it. ECM showed max rpm of 7100 and change! Yes, the noise level was insane.
I don't doubt they would rev higher than that, I'm just saying anything past around 3,000 RPM, and I'm not trying to save it anymore. I'm getting away from the damn explosion that's about to happen
id be surprised if that thing was any less than 3k. look at the smoke. and governor's dont mean anything to a runaway. this thing was going as fast as it could spin
I agree. And that's why I probably wouldn't try this. As a company driver I do what I can to prevent a runaway from ever happening but if my truck ever starts eating its own oil I'm just going to get as far away from it as I can and let insurance deal with the rest
Could be a run away diesel, but seeing the save prob not cause only way to stop a run away diesel is covering the air intake (usualy turbo, cause thats what causes the run away diesel)
Unless you can load the engine enough that it can't overcome, which is what it looks like here. Probably a high gear against set brakes and luck that the clutch held.
A runaway diesel engine is where it is running out of control. (Not a vehicle driving away with no driver.) Since diesel engines run on compression ignition alone and not a spark like gasoline engines, and a runaway typically happens when fuel is being supplied in some abnormal way, shutting off the key will not turn off the engine. Sometimes can happen from fuel injectors stuck open, more often happens from a failed turbo seal allowing engine oil into the air intake for the engine, which will cause the engine to speed out of control and continue to supply its own fuel.
The most reliable way to stop a runaway is to cut off air supply, or by what seems to happen here is to supply a large load to the engine that it can't overcome (by putting the transmission in a high gear against set brakes). That is what caused the truck to buck and lift.
Thanks! That was really helpful. I always thought runaway trucks had to do with the brakes, bc you see emergency ramps on the mountain passes (like the Eisenhower).
So he is just going to let the engine run at full steam until the fuel is spent?
No, they stopped the engine, that was what the bucking was. The engine turning against the stopped wheels and levering the engine against the frame and drive system. After it’s stopped it’s not going to be running.
Again, this is a runaway engine not a runaway truck. Those ramps are for failed brakes on downhills.
He removed the air from the airbrakes so the trailer was immobile, a runaway diesel feeds engine oil to itself until it runs out but he put the engine in drive and it immediately stopped the engine since the trailer brakes wer3 on
When my turbo blew out and started grinding bits of metal. Had to roll 2 KMs to breakdown area. When I started it up after waiting for tow truck it was pissing smoke like this.
10,000 grand later new turbo .
Forced the truck to shift interrupting the synchro between the motor and transmission. Aka: he stalled it. Next option if you can get the hood open is to toss a shirt or blanket or something into the intake choking the air.
Less likely it's combustible vapor and more likely it's an oil leak from the turbo feeding in. More oil means more rpm, more rpm means more oil. At that point it's feeding itself its own fuel, so shutting off the diesel fuel does nothing. Starving the air or being able to load the engine enough that it can't overcome that load (like was done here assuming by putting in a higher gear and dropping the clutch with the brakes set) are going to be basically the only ways to stop it short of letting it stop itself by failure.
Damn.. I know it's impressive and I know "it worked" and we all have the idea.. but its scary dangerous.. I know an older feller who did this to stop his runaway and the flywheel exploded and shot through the floorboard and cut his leg off..
NOT something I'd suggest..
In tractor pulling the build a cage around the bell housing because this can happen..
My suggestion is to clog up the air box with clothing of some sort.. killing the power from the battery disconnect might work too..
killing the power from the battery disconnect might work too..
Not from a diesel. Probably turbo puking oil in the intake. which in turn fuel the engine. which builds up more oil pressure. And the cycle continues. Fuel injection is out of the picture here.
With that being said. I know the dd engine has a throttle body to choke it during regen. so it might work.
Supposed to, but that requires proper maintenance. You're definitely better trying to scoot out of the way of the transmission and changing gears like the guy in the video did or throwing a shirt/coat/blanket into the intake manifold.
22 Cascadia familiarity here: it shuts the motor off if I open the hood latch at least during Opti-idle (at least supposed to). I was off one day while my truck was in the shop. I checked my fluids after since the repair was for the lifters and I wanted to make sure that they properly topped them off. I get ready to roll, do a little cursory walk around my truck checking it in case someone hit it, leaving the Opti-idle on. I'm not going recheck fluids since I had the night before and I didn't move, truck didn't do a lot of on/off throughout the night since it was fairly cool to the temperature sensors. Anyway, truck starts itself up and lo-and behold someone had popped the strap to my hood. I know that I had latched it the day before because my hood didn't wobble around when I scootched around the yard to park.
I did ask about it but the shop tech just looked at me like "of course it'll run with the hood open. How else can we listen to an unmuffled motor?"
TL;DR: don't trust the sensors. Just pay attention to the truck, take care of the machine and be ready to do something janky if you want to try to prevent it from becoming a ball of fire.

No they wont. The most an engine can pull is pure vacuum, which would be 14.7psi on the atmosphere side of whatever is blocking the intake.

A throttle body will never be perfectly sealed. Unless there is a lot of force and a perfect seal then a runaway diesel will find air.

They don't find enough air to run. I've stalled them out with a jumbled up tarp.
