Combustion Engine: mp;2oil 3 MJ/tmp;r (one bucket ≈ 4 min) or mp;2fuel 6 MJ/tmp;r (one bucket ≈ 21 min).
Its heat rises with the output (faster in deserts). mp;4Above 100 °C it needs watermp;r, which keeps it at 100 °C – fuel ≈ 2 mB/t, oil ≈ 1 mB/t.

Without water it reaches 250 °C after 10–15 minutes: it shuts down and the coolant boils away. Right-click with an empty hand or a wrench resets it.
In the menu: put buckets (water, oil, fuel) or ice into the slot – the content flows into the right tank.
Continuous operation: a 
Pump on a water pool (3×3 or more = infinite) and 
fluid pipes to the engines. Fuel from a 
Tank via a
