Combustion Engine

Combustion Engine

The Combustion Engine is the most powerful engine in BuildCraft and is able to use combustible fuels as a way to produce power.

Information

To make use of these combustible fluids, they must be piped into the engine along with a coolant to keep them from over heating.

Different Fuels

With all combustible fluids, they produce different amounts of power for different amounts of time depending on which fuel is used.

Using dirty fuels in an engine will cause it to get clogged up with residue which you would need to extract.

Engine Mechanics

BuildCraft engines have 5 temperature stages, which determines the speed the engine runs at: Blue, Green, Yellow, Red and Black. Combustion engines will only turn black if the engines internal power buffer fills up as the power has nowhere to go, thus the engine will overheat and needs to be wrenched to be cooled. Engines will always connect to the nearest compatible MJ consumer. You can use a Wrench to rotate it to change which block it is powering.

Combustion engines can be "chained" in a line with up to 5 engines in total.

As with all engines, it requires a redstone signal to run. Gates can be used to detect the engines temperature stages to help you control them.
