Hi, has anyone measured what element it emits, it's temperature and mass/sec (launch sequence, takeoff, landing if the values differ) for all four engine types? I still have not yet switched to the SU version and can't test myself, thanks.
All engines emit some sort of gas:
Steam: ["low temperature"+50] steam (probably boiling/condensation point, so 150C and thus 323K)
Petrol: 1500K CO2
Hydrogen: 2000K steam
All engines additionally heat up a column 3 tiles wide and 10 tiles tall below them by their exhaust temperature divided by distance from the engine. This is hard-capped at 3200K.
For example, 3 tiles directly below the center of hydrogen engine should get +2000K, 3 tiles below them should get +10
