I would recommend not running the engine until the fuel is drained. Any amount of petrol/gasoline in a diesel can cause engine or fuel system damage.
to resart the computer if it crashes or freezes
freeze out plugs are metal plugs in the block and heads of your engine. they are are there if the coolant was mixed wrong with to much water and the vehicle freezes they will pop out allowing expansion of freezing liquid hopefully saving the engine Part 2: You will see these called freeze plugs, casting plugs, welsh plugs and probably other terms. The holes they plug are part of the cylinder block casting process to allow molten steel/iron/aluminum to rapidly flow into the block casting mold. The fact that they will pop out if the coolant in the engine freezes can be serendipitous but in most cases the plugs go bad due to galvanic action: the steel plugs installed at the factory are dissimilar to the engine block metal and will start to corrode (rust) and will start leaking after a while. This is why most antifreeze manufacturers claim they have anti-corrosion protection; it is also why 99% of replacement plugs are brass. Three points to remember: 1) before replacing plugs do your research and find out EXACTLY how many plugs your engine has and where they are. 2) if you have to replace one plug, replace them all. 3) if you are rebuilding an engine it is cheap insurance to replace the plugs.
a teleporting machine a micro freeze that freezes instead of melting
When you say "plane jet" i assume that you're refering to a jet engine. When something gets stuck, this is called a bird strike. If your engine is an older one ( or if it is not "bird strike resistant certified") then the object will either wedge itself or splatter upon impact, and can jam the air blades inside the jet, causing the engine to fail and the plane to crash. If your plane is resistant to birdstrikes, then the engine will just grind up the thing and it will fly out the back. I hope i answered your question.
Depends. If it just becomes mushy or freezes very little, probably no damage will be done. if it freezes solid, you will have severe internal engine damage. Cracked block, or cracked head is common.
It explodes and the apocalypse happens.... What do you think happens? it freezes
it's freezes
As the water freezes, it will expand.
It can break the water pump housing, engine block, radiator. Major damage.
The parts inside warp and the engine freezes up. After that comes a major overhaul.
It burst out.
it gets cold and freezes
Engine oil will not freeze at any temperature you will encounter. The freezing point is not fixed and depends on many factors. Oil will however get thicker as the temp goes down.
it remain the same as it has definite volume.
It freezes.
Water freezes.
