Stopping a screaming engine...

Just a thought that popped into my head the other day after reading a few threads about Diesel engines running away on engine oil, so I thought I'd get the consensus off you lot!

If an engine is providing its own fuel through sump oil, and presumably you can't stall it in 5th gear with the brakes, would a CO2 fire extinguisher kill the combustion process?

Here's where a snorkel really would come in handy! Being able to dump a shed load of co2 into the inlet should in theory break the combustion cycle and slow or stop the engine, but would it be enough?

Over to you gents....

I reckon yes if it were a reasonable size extinguisher but a lump of wood over the intake is preferable..

1. Brakes are more powerful than engines.

2. Block the inlet with anything but flesh.

Yes, unless it has an autobox, then you're fooked....
Best approach to this is prevention; occasionally checking the manifold air intake for excess oil to gauge the health of the turbo, because if you've ever seen or heard a run away diesel, you'd know you wouldn't be tempted to go anywhere near it to even attempt blanking off the intake to shut it down.

..or kittens

Now I'm confused - I should or shouldn't use kittens?

Kittens are fine, as long as they are larger than the inlet diameter; the fur on smaller ones buggers up turbochargers. Fluffy ones are especially good when damp.

Kittens should always be used,because kittens grow up into cats and cats are basically cnuts.

:d

till you rip the arse out of the clutch

I would have thought that CO2 will work.
A 6kg extinguisher lasts 15 seconds, this should give the engine time to come to rest.

But would the very cold temp do damage to the engine ?
I know it's still better than self destruction, but would it crack the head or something.

As long as it stalls it cheaper fix than an engine
