Just north of M1 Jnc 28 about 10am today, I managed to slip by a truck on the hard shoulder with a runaway engine before they closed the whole lot.
It really was ZERO visibility when passing through the cloud & it even filled my cab with smoke.
Considered pulling up in front & pointing out that you need to stall it to stop it when the thought occurred to me it was probably an auto & I might be wasting my time.
Can you stall an auto?
when we had this on a auto I put box over the fiiler
it was the turbo oil seals that went and it stated to ■■■■ oil out of the intercooler an run on its own oil
Bang 
A smaller engine, but still quite spectacular …
I tried stalling a runaway engine many years ago, all it did was destroy the clutch as well as the engine.
Whist you can’t stall a conventional auto you can stall the current truck fitted autos, put one a high gear and set off with no throttle and try it!

That much smoke x6, then gently waft it over 6 lanes of M1.
It really was ZERO visibility in the cloud, there was so much smoke entering the cab that I’d probably have choked to death if I’d stopped.
Must’ve been really scary for whoever was driving the runaway !
That’s why I posted that video … it’s very easy to say “stay in the cab and stall it” or “put something over the air inlet”, but I can’t imagine doing anything but getting the hell out of the cab and away from the vehicle if that happened to it!
That’s when a CO2 fire extinguisher comes in very handy!
Quick squirt down the air intake=stopped engine 
I was going southbound just as it let go. I’ve never seen so much smoke in my life. It was a white Cf Artic can’t remember the company.

How do you ‘set off’ with no throttle, the clutch won’t engage until you apply throttle.
I don’t think you can deliberately stall a “runaway” with a modern automatic transmission - The computer that controls the gearbox will “see” the high revs and will simply not allow the clutch to engage.
Does make you wonder if worth the prudent owner (preferably standard fitting but elfinsafety would have a kitten) fitting a simple flap in the air intake, in the event of runaway the flap can be used and all intake air cut off, probably too rare an event for such consideration.
Another DAF with a Turbo problem…No way of shutting it down, until it throws a rod and then it`s all over
You can even burn the brakes out trying to stop the buggers 
Could just keep going and burn the clutch out even in a manual.
Need something like a jacket in the air intake but would need to tilt the cab or get in the air box. Has to be largeish like a jacket as it’ll be sucking like a ■■■■■ that’s swallowed a Dyson.
Just let them go, much better in the long run, complete engine instead of bits. These CF’s do seem prone to turbo problems though.

Maybe your firm should have the brakes looked at never mind the bloody turbos
foot brake full on,into first gear and try to move it.If that dont stall you need major brake work done.

1st gear?
The Detroit engine has an emergency stop built in to it . It consists of a spring loaded flap in the inlet manifold which shuts when the handle is pulled in the cab shutting the air off, they have had this facility since the early 1940,s . A handy little gadget that saves a lot of hassle and saves an engine from total distruction.

Thats what i’m talking about, simple cheap and effective…oh hang on a minute this is 2013, it’ll need to be computer controlled and linked to telematics and will need NASA approval before being invoked, then there’s the training course in how to use it 
How do you ‘set off’ with no throttle, the clutch won’t engage until you apply throttle.
point taken, try using minimum throttle.
re the suggestion of engaging first gear and applying footbrake, all that happens is that the clutch fails.
been there , done it.

Agree about first gear, there’s not much energy in engine oil the thing is running on at this point so stalling should be possible in a higher gear.
I expect in practice these poxy gearboxes won’t accept any gear selection with the engine revving its bollox off, about as much use as a chocolate teapot.
Over the years had several of these auto-rubbish things stall on me, both Scania and MAN (several times) always when in auto mode when they selected gears too high for low road speed such as junctions and the torqueless at low revs engines unable to cope, now i only drive the heaps in manual override so wrong gear shouldn’t happen…in theory anyway 
By the way didn’t some LandRovers have this self destructing habit, but caused by seal failures in the pumps so running on Diesel instead, again a real simple stop switch would have been an easy cure.
