Create Aeronautics: Portable Engine Liquid Fuel
by XenraO
Liquid fuel for the Portable Engine lets the engine burn fluids such as lava that arrive through pipes, not only solid fuels.
What it does
The Portable Engine normally takes solid fuel. This mod adds liquid fuel support, so the engine can consume fluids like lava fed through pipe systems. Servers and players both need the mod installed, since the environment is client and server.
Custom fluids can be added through a datapack. Entries can be limited to load only when a chosen mod is present, and a replace option avoids overwriting existing entries. Both options can be used together. The mod is for NeoForge on 1.21.1 only and is released under the MIT License, but it is not open source.
Key features
Liquid fuel intake
The Portable Engine accepts fluids such as lava delivered by pipes, alongside its solid fuels.

Conditional and safe entries
Entries can load only when a specific mod is installed, and a replace option prevents overwriting existing fuel entries.

What the author says
Adds liquid fuel support to the Portable Engine from Create: Aeronautics (Simulated). Instead of relying solely on solid fuels, the engine can now consume fluids like lava through pipe systems. Both neoforge:conditions and replace can be used together — they are not incompatible.
