Combustion Engine

The Combustion Engine is the most powerful engine in BuildCraft and provides 10-60 Redstone Flux per tick (RF/t) depending on the fuel source.

Usage
One Combustion Engine can adequately power all BuildCraft machines, however two are required to fully power a Quarry or a Refinery. The Combustion Engine is fueled with lava, oil, or fuel, but unlike the other engines, it must be cooled with water or the engine will explode. It can be filled with water using pipes or buckets. It needs a redstone signal to operate.

Power
The amount of RF/t that the Combustion Engine produces depends on the type of liquid that is used:

The smaller colored side of the Combustion Engine is the side which is providing power. The orientation of the engine can be changed using a BuildCraft wrench.
