We had a Hino truck runaway on us about 10 years ago. It's a cherry picker truck setup and it isn't fun being 15m up in the air when the all of a sudden the motor starts revving it's gaskets off... and no emergency stops worked!

Yeah I just suffered the same thing.... oil seal in turbo blew and oil blew through the intake. Engine very quickly climbed to 3500 and with my foot on the brake I pulled into the nearest drive way and stole their garden hose, soaked my shirt and wrapped it around the filter. Starved it of fuel and after about 10 seconds the engine stalled itself.
Then a rather red faced home owner comes running out wondering what all the noise was and why there was a shirtless fat shit standing in his driveway

Hi !
Air intake shut off systems are the only proven, reliable method to stop a diesel engine once it has begun to run away. IMO of course

I've had this happen on 2-stroke dirt bikes when they are hot enough and lean out, only lasts for about 20-30 seconds though.

Ha! Hows about a runaway petrol? Kind of, sort of.... Early bird visit to the butchers before GF crowds supply stock-up this morning and saw a bunch of folks around a popped Y62 bonnet in the car park. Car won't shut off. Keeps on idling. Key in/out, button presses did nothing. Positive 12v disconnect killed it swiftly.
Got me thinking. TD is a dumb diesel motor. Older non-electricy ones would keep on trucking without 12v once started.
But how about the new-ish ones with that NATs shut-off valve on the pump and the #1 injector somehow being tied electrically (nuffy here speaking).
Would they shut off without 12v?

Our old TD42 still need 12V to keep the fuel solenoid open.

Really ??
We took a battery out of a running GQ and put it into a dead alternator/ battery, Dmax so we could limp it to towable grounds.
GQ kept chugging along.

Didn't kill the alternator on the Q? The regulators really do not like having an open circuit.
My advice is: not to follow my advice.
