Fuel can be inserted into burner devices and burned to power them. Different types of fuel provide different amounts of energy, measured in megajoules (MJ).

Types

This is a list of all items usable as fuel in burner devices, ordered by fuel value:

(1) For the purposes of in-game speed display, the game assumes 1 tile = 1 meter. I.e., a train on basic fuel travels at 72 tiles per second at full speed, and so on.

(2) This assumes the crude oil is processed completely into solid fuel using advanced oil processing and heavy oil cracking as intermediate steps, but not light oil cracking. More efficient methods are possible. In practice, the petroleum gas is more likely to be used for something other than solid fuel.

(3) This fuel type can only be used in a nuclear reactor. Unlike other fuel types, it cannot be placed into standard burners.

(4) Assuming that all U-238 is enriched, all used up cells are reprocessed, and there is no reactor neighbor bonus.

Consumption

The following formula can be used to find how long a fuel will last in a device: Burn time (s) = Fuel value (MJ) ÷ Energy consumption (MW)

Trivia

  • Though the top speeds given by solid fuel, rocket fuel and nuclear fuel are presented as +5%, +15% and +15% respectively, this seems to only be true for trains. The top speeds for cars and tanks are instead approximately +9.5%, +34% and +58% respectively when these fuels are used.

History

  • 0.15.0:
    • Fuel type affects vehicle acceleration and top speed.
