What it does#

The Caloric Engine burns anything a furnace burns and turns it into FE. It makes 40 FE/t while it has fuel, and pushes that power out of its front into whatever is touching it.

Fuel is worth more here than in a furnace. A piece of Coal gives 60,000 FE, enough to run the engine for 75 s, and the engine lights the next item before the last runs out, so its output doesn't dip between items.

Building it#

######

Using it#

Put fuel in its one slot, by hand, by hopper, or by turning on auto-input. Click the tabs and the coloured faces below; they behave like the real screen.

• Burns any furnace fuel for FE
• Pushes FE out of output faces
• Auto-input pulls fuel from neighbours
• Celerity: more output, more fuel per FE
• Economizer: more FE per fuel item

1. 1
   The engine's own store of power. It fills while nothing takes the FE and empties as neighbours draw it.
2. 2
   Running while it burns. Idle when it's out of fuel; Disabled when redstone has switched it off.
3. 3
   The fuel slot. The flame above it lights while fuel is burning.
4. 4
   What it makes each tick, how full the buffer is, and how long the item now burning has left.

   Which faces take fuel and which push power. Click a face to change it; right-click to go back.

Fuels#

Every furnace fuel works. Most are worth their furnace burn time × 25 FE × 1.5, rounded to the nearest 250 FE; a few have a set value of their own. Some common ones:

Fuel	FE per item	Burns for, at base rate	Value from
Coal	60,000 FE	75 s	burn time
Charcoal	60,000 FE	75 s	burn time
Block of Coal	540,000 FE	675 s	fixed
Blaze Rod	80,000 FE	100 s	fixed
Dried Kelp Block	100,000 FE	125 s	fixed
Lava Bucket	200,000 FE	250 s	fixed
Oak Log	11,250 FE	14.1 s	burn time
Oak Planks	11,250 FE	14.1 s	burn time
Stick	3,750 FE	4.7 s	burn time
Sawdust	3,750 FE	4.7 s	burn time

Automation#

Out of the box it powers whatever its front touches, no cable needed:

Front Output (pushes FE); Every other face Input (takes fuel). Auto-input off, Auto-output on.

Feed fuel by hopper or pipe into any input face, or turn on Auto-input to pull it from a chest beside it. Side configuration explains faces, modes and redstone control for every machine.

Upgrades#

A tier kit raises its output and buffer and opens module slots.

Tier	Kit	Output	Buffer	Module slots
Base	None	40 FE/t	20,000 FE	0
Tempered	Tempered Upgrade Kit	80 FE/t	40,000 FE	2
Fortified	Fortified Upgrade Kit	120 FE/t	80,000 FE	4
Luminous	Luminous Upgrade Kit	160 FE/t	160,000 FE	6
Harmonic	Harmonic Upgrade Kit	240 FE/t	320,000 FE	8

• Celerity Module · up to 4
• Economizer Module · up to 4

Engines trade their two modules against each other:

• Celerity raises output by 50% each, but every item of fuel gives less FE.
• Economizer adds 34.375% FE per item each and 25% buffer.

Four Celerity modules triple the output, 3×, at 33% of the FE per item. Four Economizers get 2.375× the FE from every item at the same output. Four of each give 79% of the FE per item at triple the output.

Good to know#

• Its running sound is a crackle over a low hum. Turn it off with Sounds on the Configuration tab.
• With Jade installed, looking at the engine shows its output and the fuel left.
• Sawdust from the Kerf Mill is fuel, so a log-sawing line can feed its own engine.
