The Pneumatic Engine converts PneumaticCraft energy to RotaryCraft shaft power. Pressure tubes must be attached to the back of the engine to give it power. It can store 36,000 MJ of energy, displayed in the GUI.

The GUI features controls which allow precise control of the Pneumatic Engine's output. The Pneumatic Engine takes no time to "spin up" or "slow down," and carries no risks whatsoever except those common to all engines(such as overloading shafts, which can happen very easily).

The engine's reaction to redstone signals can also be configured. The gunpowder icon indicates that it ignores redstone signals, while the lit and unlit torches indicate that it only turns on when its redstone signal is on or off, respectively. The icon can be clicked to toggle between these modes. Note that it will immediately turn off if it swaps to a mode where the signal requirement is not met.

The Pneumatic Engine's input rate has no direct effect on its output. However, certain input rates are required to sustain a given output without it eventually draining all stored energy. If it drains all energy, it immediately stops. It restarts after its stored energy comes back up above a certain amount.

Rotarycraft Handbook DescriptionEdit

"The pneumatic engine uses a turbine to convert pressurized air from BuildCraft conductive pipes into shaft power. Use its GUI to choose the torque and speed output. Higher power outputs will require more air pressure (more MJ per tick)."

SpecificationsEdit

Torque 2048Nm
Speed

Up to 2048 rad/s*

Power Up to 4.194 MW
Power Source BuildCraft Energy
Requires Consumables Lubricant
Risks

None

*The maximum output speed is 2048 rad/s, and the torque is fixed at 2048 Nm.


Conversion ForumlaEdit

The specific conversion rate for the engine is 1 MJ/t = 51.2 kW. This is the power provided by a single Stirling Engine. By contrast, a Combustion Engine running on refined fuel can provide 6 MJ/t = 307.2 kW.

The following table lists the minimum MJ input required to fully sustain certain outputs. A quick reference point is that 5 MJ/t sustains one quarter of a megawatt(256 kW). FCE shows the number of Fuel-run Combustion Engines required to sustain the given output.

MJ/t Power Note FCE
0.02 1.024 kW 1
0.04 2.048 kW 1
0.08 4.096 kW Redstone Engine(cannot be connected to kinesis pipes) 1

Tips & TricksEdit

  • The table above does not indicate a requirement for sustained input. The input doesn't have to be sustained or even existent for the machine to run off of its stored energy. 36,000 MJ will, for example, provide 262.144 kW of power for (36,000 / 5.12) = ~7,031 ticks = ~351.6 seconds.
  • When the torque or speed is adjusted, the effect takes place immediately as long as there is stored energy. Any shafts or flywheels connected can be overloaded instantly.
