What it does#

The Ignition Engine burns oils and refined fuels and turns them into FE. It makes 100 FE/t while it has fuel, the highest base output of the engines, and pushes that power out of its front into whatever is touching it.

The fuel decides the value. A Crude Oil Bucket is worth 100,000 FE; the same bucket of refined gasoline is worth 400,000 FE, four times as much. Refining pays.

Building it#

Using it#

There is no fuel slot. Fill the tank with a bucket (use the bucket on the engine) or pipe fuel into an input face. Click the tabs and the coloured faces below; they behave like the real screen.

  • Burns oil and fuels from other mods

  • See JEI for every accepted fuel

  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 the tank is empty; Disabled when redstone has switched it off.
  3. 3
    The fuel tank. Hover it for the fluid, how much is in it and what a bucket is worth. It can be filled but never drained, so it only ever gives its contents to the engine.
  4. 4
    What it makes each tick, how full the buffer is, and how long the whole tank lasts at the current output.
  5. 5
    Which faces take fuel and which push power. Click a face to change it; right-click to go back.

Fuels#

Any fluid carrying one of the tags below burns, from Enthalpy or from another mod. A tag that nothing in your pack fills simply stays empty. Enthalpy makes crude oil, vegetable and fish oil, ethanol, biodiesel and gasoline; the fuel chains guide shows how to get from raw material to the best fuel.

The Vortex Separator makes crude oil, plant oils and, in its fluid mode, gasoline.

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.

Pipe fuel into any input face, or turn on Auto-input to pull it from a tank 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.

  • 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 bucket gives less FE.
  • Economizer adds 34.375% FE per bucket each and 25% buffer.

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

Good to know#

  • Hovering the tank shows what a bucket of the fluid inside is worth, and with JEI installed it offers a list of every accepted fuel.
  • The engine draws fuel from the tank in small sips, so a half-empty tank still runs at full output.
  • 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.

Fuel values are in the enthalpy:ignition_fuels fluid data map, keyed on fluid tags, so any mod that tags its fluid is picked up.
