The stirling engine is significantly more powerful than a basic Redstone Engine, but uses fuel such as Coal. It will slowly gain heat if it is producing more power than is being extracted from it and eventually explode if it reaches 120 degrees.

Stirling engines (formerly incorrectly named steam engines) are the second tier of Engines. They use cobblestone instead of wood or iron so are still cheaper than the Combustion Engine. These engines cannot explode unless there is an oversupply of power. Note that the flame gauge on the Steam/Stirling Engine GUI does NOT indicate if it has any energy to run or not, but rather if there is still fuel being added to build up heat. In other words, the stirling engine continues to run quite a while after the instant the flame gauge empties and there is no more fuel in the slot to burn (unlike Vanilla machines).

Stirling engines output 1MJ/t while on (given a redstone signal). The stirling engine runs on burning items and so needs refueling to continue operation. Burnable items include lava buckets, coal, charcoal, coal coke, wood, planks, sticks, saplings, crafting tables, chests and bookcases—basically it will burn everything a normal furnace will burn. The stirling engine is turned on/off via a redstone signal and requires an active redstone signal to run.

Fuel MJ Time, seconds
Cactus, Sugarcane 50 2.5
Stick, Sapling 100 5
Plank, Log, Scaffold 300 15
Scrap 350 17.5
Scrap Box 3150 157.5
Charcoal 1600 80
Coal 1600 80
Coal Coke 6400 320
Lava Bucket 20000 1000

It is impossible to pump lava directly into the engine, players can only place buckets of lava in.

Steam Engine gives significantly more MJs from a unit of fuel than this engine, but can not burn lava buckets.


Stirling engines can be used as a power supply for mining machines, and can be connected to each other or can transfer power through Kinesis Pipes.

Though all BuildCraft engines run at the same speed when hot (1 cycle per second) the Stirling engine produces 20 times more power than a basic Redstone Engine.

Stirling engines are a good choice for powering a Pump for 1 or 2 Combustion Engines, while if you are using more, a combustion engine will be needed for the water supply.

On the GUI extra-window it shows how much "heat" and MJ is stored, if the stored MJ value goes too high (1,000) the engine WILL explode, so players shouldn't produce excess power.


  • As of BuildCraft 3, applying this engine to a Kinesis Pipe shall always take off the amount of MJ stored, making it not be able to explode, however the MJ in the pipes need to be used or these shall explode.
  • As of BuildCraft 3, it wasn't possible to rotate the engine using the wrench.
