True, military uses halon in all their wheeled and track vehicles that have fire suppression systems.co2 will work fine no need to get expensive both displace air
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!

Now that is a handy size ! With a remote activated switch, it would work like a champ.Anyone decide to assemble a CO2 bottle into the fording hole yet? I came across some small bottles that could be used.

480 cubic inches, 240 per revolution as it is a 4 stroke. 3600 rpm so 86400 cubic inches per minute, that is 500 cubic feet. One pound of carbon dioxide is about 8 cubic feet so a one pounder needs to be discharged at 8/500 minute, roughly one second.I understand the concept of using CO2, but, has anyone considered the number of cubic feet of gas needed to completely displace the O2 being pulled into the engine and that this flow will have to continue until the rotating mass comes to a full stop or they will just re-start?
Just a thought......
That is why I said a 5 pound extinguisher would be needed. If there is an intake butterfly valve, then far less would be needed as manifold pressure would be reduced. My TDI has such a device to prevent shut off shudder, works well to kill the engine too when I have had to override the electrical fuel shut off due to immobilizer malfunction (hot-wire to injection pump shut off solenoid, this is an electronic modulated version of the LDT/LDS injection pump).Keith_J
Check your math. They will be pulling roughly 500 CFM (just over what the air cleaner is rated) at that speed, and at 8cf per pound that is 62.5 pounds, and that assumes that the engine comes to a full stop in 60 seconds from that speed.
What you need to consider is 1) The engine will not be going 3600 rpm. 2) When you shut-off an engine, it will slow down and stop much faster since the compression is NOT helping to turn the crank. Just for grins and giggles, go out and check your truck. See how fast it will stop turning after you shut-off the fuel. It is a lot faster then you think.480 cubic inches, 240 per revolution as it is a 4 stroke. 3600 rpm so 86400 cubic inches per minute, that is 500 cubic feet.

sounds like a five pounder is necessary.
During a run-away as the original poster had happen, engine speed would be very high. The issue of fueling from lube oil would require choking or extinguishing with carbon dioxide.What you need to consider is 1) The engine will not be going 3600 rpm. 2) When you shut-off an engine, it will slow down and stop much faster since the compression is NOT helping to turn the crank.

frank8003 I ask is that picture and information inside the TM’s or in a work order somewhere at the end of a TM?[/QUOTE said:Found it.
One would think but at that rpm your more inclined to breaking something, although if it stalls the engine it might be worth it.There is all this talk about CO2, would putting it in 5th and stalling it not work?
