Ahh ok. TY
I think the driver of the runaway is committing an offence by running a vehicle on the highway without having paid excise duty on the fuel
I think that Doctor Diesel originally designed his engine to run on ground nut oil (peanut butter)
Diesel (the person, not the fuel) designed the diesel engine to run on anything which would ignite solely under compression. He even experimented with coal dust, but couldn’t build something strong enough to contain the massive compression ratio needed to ignite it.

They run VERY well on veg oil, depending on the fuel pump.
We drained an old Vx Cavalier of any trace of diesel 30yrs ago, when using veg oil was only just beginning to surface. My mate ran it for nearly 6mths & swore that it performed better with more MPG.
Some tripe on here.
40 years in the job seen turbos split,sieze,explode even but one where the “cold” side seal blows,pumps oil into the engine after filling a 20 litre intercooler with oil.then the engine burns a low aromatic fluid like oil in the chambers without first locking by trying to compress a fluid is one I cant wait to see.
And dont give me that bollox about oil “mist” in the charge air.If you remove the diesel that engine stops.

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.
Detroit with an inlet flap. My ■■■. bloody 2 stroke.

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 buggersMaybe 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?
Yes first gear if the wheels are locked you can put it in ANY gear and it will stall the truck,why put it in a high gear?Brakes should overcome any crap 5 or 600 bhp bloody truck engine if they are working.2000nmtr at the flywheel is bugger all compared to 2000nmtrs at each wheel.
You ever see the video of the stupid French police trying to drag trucks off the road during a strike with their brakes on.Even the bullcrap french army couldnt move them with tanks.
I run my 4x4 on a mix of 90% used veg oil and 10% petrol most of the time. I occasionally fill up at ASDA or Tesco.
I don’t get any problems with fuel pumps but so have to change filters fairly regularly

So if by removing the derv you stop the engine how come the engine can continue to run once the fuel has been switched off?

I know there was a spate of Daihatsu Four-Track runaways, and this was caused by a combination of factors
-
Worn injectors dribbling fuel into the cylinders
-
Worn rings letting the fuel dribble past into the oil
-
Oil level rising as a consequence until the pistons splash and squeeze the diesel/oil mix back past the rings into the combustion chamber.
And voila! The unstoppable diesel!
Many years ago I was given a Rover 216S as a company car (it was their way of saying I had got as far as I was going). I could park outside my house, go indoors, put the kettle on, go back outside and the thing would still be running on…on petrol, with fuel injection!

Its an urban myth that a diesel engine only runs on diesel! I have seen big diesel engines run to destruction after a turbo failure, the turbo has exploded first and is then followed by a hole in the side of the block where it chucks out conrods for fun.
Speak to any Lister Petter engine owners- they were/are well known for sucking up the sump oil and blowing themselves to bits- no diesel required once its started to runaway
And the reason you use a higher gear to stall simple by stalling that way you are putting less torque through the clutch minimising the risk of destroying it,

Shhh
The grown-ups are talking.
I remember back in the 60’s the coal merchant next to our garage fired up his four pot TK Bedford and the pneumatic governor diapragm had split. The engine screamed its head off and the guy smashed all the fuel lines off with a coal hammer but by then it was running on the sump oil, he even managed to smash the injector pump in half and still it kept roaring away! Our foreman stuffed a coal sack over the airfilter and it eventually died, funnily enough the engine was fine after the pump was repaired, I bet there wasn’t much carbon left in the ports though!

And just by turning off the key how do you know the ecu has shut down?When trucks had H4 headlights if you held the high beam on and turned off the ignition the engine kept running by back feed through the headlight flash stalk and if you got melted headlight elements the power from the dipped beam also kept the motor running if you stopped the truck with the lights on.

Well you learn a new thing every day BKING…They DAFs are indeed passing oil in to the intercooler and then in to the inlet manifold,where it is happily injested by number 6 cylinder and bending a conrod …Meanwhile engine oil is also happily making it’s way in to the CAT …
Obviously if just pottering or manouvering when it blows and the driver is alert ,you can get away with just the turbo. But if overtaking on a dual carriageway ,then all of the above will probably happen
Other makes may respond differently to a blown turbo

I remember the good old 432 APC with an hydraulic governor ,and the fun we had when that sprung a leak …A fire extinguisher soon stopped it

Funny that, considering that I get a few cases a year of diesel engines self-destructing from the exact thing you happen to disagree on! Not a nice thing to witness happening either…
