How to make and add your own fuels!

How to make and add your own fuels to use in planes/cars/boats/ekranoplanes/catapults?/helicopters/tanks/and whatever else (die glocke)

The adding fuel part

You can right click the game in your library, a menu pops up, here's what to do: Manage > Browse local files, then it takes you to the files, then go: Flyout_Data > StreamingAssets > Fuels, you can then drop any fuel files you find on discord, there.

The Making fuels part.

If you are looking to replicate fuel, research it and fill variables accordingly, if not, make your own, here's how to do both (this is as far as i know)

(you can copy a file and change things to get what you want)

Take a look at the screenshot of what you will see in files,

here is what they mean:

id: fuel identification number (cannot be the same as an already existing fuel.)

name: In game name

density: Fuel density, volume/weight in g/cm³

specific_energy: {joules/kg from burning}

heat_capacity: This is the specific heat of the fuel in Joules per Kelvin per kg. It's the amount of heat in Joules needed to raise the temperature of 1 kg of the fuel by 1 K.
It's basically a measure of how much heat it "steals" from the combustion energy to raise its own temperature. Thanks to Sundae for clearing this up.

stoichiometric_ratio: stoichiometric ratio is the ratio of air and fuel needed for efficient combustion, IE the ideal fuel to air ratio for gasoline it is 14.7 parts air 1 part oxygen, and its different for other fuels, like for nitromethane its like 8.3:1 (thanks to frenchfry for the comment)

auto_ignition:Auto ignition temperature. In kelvin

freezing_point: Freezing temp in kelvin


Thanks for reading, if you have further questions or inquiries my discord is "mrthermonuclear")

hope to see your custom fuels in the flyout discord!

@The Tour Guide: you have ID conflicts set the id to a different number (must be unique)

[Korvoid]

@Sadigov uh that's probably because it's missing a id so if you add "id=15" or similar (id has to be unique), then that should work

[The Tour Guide]

whenever i make a fuel, it doesnt show up in the game, well it does but it overwrites Jet A, and it makes two of them, completely the same. Help

[sadigov]

Koevoid, your fuel does not work for some reason

[Korvoid]

I pretty much second what hydrophobic water said, but you can go lower with the heat capacity, and I think the other way with the stochiometric_ratio, that is burning 1*e^-19 kg's of air per kilogram of fuel, which will make it incredibly inefficient, though require a lot less air.
and auto ignition can probably sit at about 2000-2500 if your using it in a Jet engine.

and as i'm in the process of working it out anyway, this is what liquid Hydrogen (which is a great fuel looks like:

name=Hydrogen
density= 0.07085
specific_energy=142000000
heat_capacity=8100
stoichiometric_ratio=34
auto_ignition=858
freezing_point=14

this should be quite a good fuel but I'm not sure how functional it'll be in a jet engine on the basis that it's auto ignition point is quite low and it has a high heat capacity which might create preignition, so it might be worth adjusting by decreasing the heat capacity, and increasing the auto ignition point

[Hydro-phobic Water]

a good starting place is
specific_energy=418400000000000
heat_capacity=246
stoichiometric_ratio=.0000000000000000001
auto_ignition=9999999

no idea of what practical/actual limits there are other than I think energy, going too high causes issues.

[asunder]

specific energy and density, along with stoichiometric ratio are the ones that would help with that most, just mess around and add zeros

[PowerBongo18457]

How do i create an extremely powerful fuel

[Sundae]

@mrtweak Sure

[asunder]

@Sundae thank you, and I'm sorry, may I add the comment to the guide?
