It would be cool if you had a bad crash or rear ended that the tank would rupture making the engine cut out and in the end stopping the engine, and in extreme case igniting.
Fuel leaks are implemented, and it is possible for the engine to cut out from lack of fuel. Unless you're driving a Pinto, explosions are highly unlikely. Furthermore, explosions are more trouble than they're worth to code. (or are they?)
explosions.... while they are cool, cars dont explode... i know they can, very unlikely, have a fuel flash fire / fireball if leaking fuel gets ignited, but an explosion needs a contained material ignited and causing the contianment to get destroyed by the pressure inside which then gets released very fast and causes destruction, everything else is just a flash and has not enough power to destroy anything on the car like we see it in movies but maybe a window with luck. i would get a rather runrealistic gameplay feeling from cars exploding more than once in a real life month while crashing cars in beam ng every day. its just too unlikely as i think.^^
well then, ingition of rest fuels spit over parts near the fuel tank which got crushed would be pretty nice of course. ^^
Yes, but if the explosions do work, I think this would be best on the Gabester's Gavril Grand Marshal (Probably) and Nadeox1's Ford Crown Victoria.
When a full fuel tank explodes in a burning car there's little visual evidence for it - but the bang is powerful, and the ground will punch you in the feet for a good distance around. Visually the most you'll see is a brief flash inside the cab and a small bounce. To do this justice, you'd really need a liquid/gas physics simulation in addition to ignition, and that simply isn't the point here. If a modder managed it I'd be impressed and very grateful, but... Not for priority attention? Unless of course it wasn't fully simulated, and was simply a set of timers attached to the series of events I described above. Still, without fire propagation and materials altering visuals due to burning, I don't think it would be worth the trouble.
If the car is on fire and the petrol tank gets hot, you do get a fireball out of a petrol tank BLEVE. There are plenty of videos of car fires in Russia with the petrol tank rupturing after it gets too hot. You can really get anything from a fireball to a flamethrower out of the arse of the car, depending on how the tank ruptured and how pressurized the fuel has become due to heat. There's no definitive way for a fuel tank to fail in a car fire. anyway, I would like to see a good simulation of car fires and the various things that go wrong with them but I'm not going to hold my breath over it
Only speaking from experience - grew up in a bad neighborhood and saw a few parked cars torched by local kids. There'll obviously be a great deal of variety in such a thing - but in general I can say it's a remarkably anticlimactic/unremarkable thing, quite the reverse of the dramatics of mainstream cinema and computer games =)
I've seen first hand a small hatchback crash head first into oncoming traffic and burst into flames, it looked much the same as the videos above. With some clever particle artistry the fire can be done easily enough. In fact the whole spilling, spreading and ignition could be done entirely in a particle system. The harder part would probably be tuning the conditions for it to occur.
Though I have seen a couple vehicles fires... They're like said before. Highly unimpressive compared to what you see in movies. However, one thing I've seen quite a bit of is engine fires in derbies in real life... Because the gas line must run from inside the car (you're not allowed to use the stock fuel tank) Generally from a 5-10 gallon tank that comes from inside the car. If the fuel line breaks, it's generally where there is the most sharp metal. I.e. the motor. Never seen a guy catch on fire, though I have seen a few fires that went inside the car. But most of them really aren't that exciting lol. Only for the guy inside!! It'd be cool to see a few engine fires in the derbies, but, meh, I can live without it
Explosions have a high chance of happening if a spark from metal scraping the ground ignites fuel leaking from a fuel tank. Then again, for an actual explosion there would have to be fuel vapor, as the liquid state just catches fire and burns.
Not necessarily, look at BJCreeper's post. I honestly don't think its necessary/realistic anytime a Grand Marchall bumps into a Covet for it to randomly "burst into flames", cars are designed better & safer, we don't live in the Pinto/Corvair age.
He does have a point but still it's very unlikely for a car to explode and yes it is very unlikely for the marshmallow and covet to crash and burst to flames. I don't want explosions or fire.
Mythbusters did an episode on exploding fuel tanks. They took a gas tank, literally set the gas on fire, and still the gas just burned. No boom boom. Not worth it to implement boom booms. However, gas tanks leaking will probably be implemented. Just keep in mind that it's still a very early alpha and many things will be implemented.
Main issue with this is that a car tank is not sealed enough to create enough pressure to cause a true explosion. There are several outlets: -The fill hole: Even if it is a metal cap on a metal pipe, it still has a rubber gasket to create a seal. The gasket will melt and release the pressure due to the heat of the fire before enough pressure can be built up to result in a true explosion. Most vehicles have plastic caps and/or the part it screws into is plastic. It would melt and release the pressure. -The fuel lines that go from the tank to the engine, if they are rubber then they would melt before the cap did. -The fuel pump may break, or the hose could become detached, this would allow the pressure to escape. If the fuel pump is *inside* the tank, then the electrical wires for it may melt and the hole the go in the tank through would vent the pressure -The tank itself. If not a plastic one that could melt, then a metal one with a rubber gasket between the pieces that could melt. -Evap system. Tanks have a 2nd line that goes to the engine. It collects excess fuel vapors from the tank and occasionally purges them into the engine for combustion. At the same time, it pushes air into the tank to replace any fuel used by the engine. Parts of this system could melt or break in an accident resulting in pressure escaping -the fuel gauge connection to the tank could become damaged or melt in a fire, the hole it enters the tank through would relieve the pressure. All of the above would just result in a slow fire or a flash over, not a true explosion. Bottom line though, is that if the vehicle is on fire, its most likely due to leaking fuel. If the fuel can leak out, then there is an outlet for pressure and pressure will not build up.
In Russia they explode. If a gas tank is or becomes air-tight, the gas can boil and cause pressure, and eventually explode
