Diesel owners, are you prepared for a runaway engine?

It is very rare occurrance, but if it happens to you, you might be even more unhappy if you haven’t got the equipment to stop it.




Stuffing a rag into the air inlet is problematic for a number of reasons, but a long blast from a “halon substitute” extinguisher will shut it down fast without damaging the engine (any further) and with no messy corrosive powder residue.




Amerex makes great extinguishers, they are commercial quality and can be refilled after use. I have a bunch around my house.


Real halon extinguishers are more effective, but very costly. They are made with recycled halon, the manufacture of which has been banned for over twenty years. Like the R12 refrigerant, when the supply is used up there won’t be any more, so the cost keeps climbing.




You can use your fancy high dollar extinguisher on a regular fire, no worries, but it just is not a good idea to squirt a dry chemical one into your runaway engine....


So, who carries an extinguisher, or two, and do you carry one like this? Have you even thought about a runaway? A blown turbo oil seal is all that is needed....

Seems there is plenty of other things to think about, this will not make the cut.


Probability is pretty low, compared to say, the 80k lbs. truck next to me, running at 75, merging into my lane without a warning.


But thanks anyways.....
