a run away diesel to me is any means that you dont have control over shutting it down IE the stop lever or key.

Well, your definition is wrong.

Every other engineer / fitter / mechanic on the planet uses the correct definition.

I guess it is just a question of whether you go with them, or convert them to your definition.

It is what it is. it's the aim of this topic to help people if their engine is un-shutdown able via normal methods not mince words and definitions..

Exactly, it is what it is, and not what it ain't.

You have a failure to shutdown or close the rack, you do not have a runaway problem.

Confusing and possibly scaring those who don't know any better doesn't help anyone on any topic.

Well, It'll help anyone who has a engine that wont shut off. So, if there's nothing constructive to post. then please dont bother. if you have a suggestion. by all means post it

if it just won't shut off, you might be able to shut it off w/ a shirt, but if its a true runaway, it'll suck the shirt right in.

ok.
calm down guys.
Aqua. you have good intentions with your answers, but a runaway is a dangerous engine destroying failure that must be controlled asap, or face an exploding shrapnel spewing failure of epic proportions.

a lack of shutdown with throttle control is a relatively simple and never dangerous problem that is little more than an inconvenience.

another problem with any vehicle is a situation where acceleration of the engine occurs, from either a stuck throttle, fuel metering problem or some other such condition, but the engine is not in danger from this conditon as the fuel is still controlled by the pump, and cannot overrev due to design.
while dangerous for driving, it can still be controlled by removing the fuel supply, or otherwise stalling the motor.

a RUNAWAY is a diesel specific problem that has SPECIAL meaning in the diesel crowd, and should not be confused with any other condition.

there are two and only two ways to get a runaway conditon.
one. ingestion of the motor with an uncontrolled amount of fuel, either motor oil dumped into the turbo/sucked in past the rings or entering an area of raw fuel like a natural gas mine, or something

two, an internal linkage problem that changes the fuel metering characteristics and as such the safety limits in the Injection pump.

that's it.

and the only safe way to fix such an actual RUNAWAY is to cut off the oxygen supply to the motor with either a board/flap shut off, or a dump of CO2 into the throttle choking the intake completely.

if someone could change the name to How to shut down un shutdown able Diesels that'd be peachy

as a side note, thanks vstech

I'll see your two and raise you one.

Seen it happen, AEC 5 cylinder (bus engine) with an oil bath air filter mounted half way up a crane, some numpty over fills the oil bath, then starts the engine...

http://maps.google.co.uk/maps?hl=en&ie=UTF8&hq=&hnear=Exeter,+United+Kingdom&ll=50.257193,-5.045021&spn=0.006194,0.016512&t=h&z=17

crane was on the left bank, newham road, where the water curves channel curves sharply to the right and shallow out, flywheel landed on the right bank just above the high tide mark literally at the edge of malpas road.

I never thought of an oil bath causing that, I have a 404ci turbo JD tractor here with an oil bath. might keep that in mind.

The old 240's had oil baths but not turbo. So unlikely to wind up. Might be a good way to get a 240 to go harder!!

to be fair, I didn't either much... before the cockney twat blew the AEC up.

having said that they're still confined to dry and dusty places so most people won't even encounter one, but if they do, that max fill line really matters..

it's not the turbo that winds up the motor, it's the uncontrolled amount of fuel (oil in this case) that causes uncontrolled RPM's and self destruction!

A block of wood to the intake pipe. If its turbo it will actually "pull it in" some, but if its a nice sturdy chunk of a 2x6", it will stop it.

I wouldn't use my hand, even on a non turbo. Because I have one of each and I wouldn't want to just accidentally use it on the wrong one.

Now, y'all, go out to your garages, locate a piece of a 2x6 and practice.
