by CARTI3R7

Create: Smart Diesel Generator Addon adds a Smart Diesel Engine block to Create for NeoForge 1.21.1, with a scroll-wheel speed control and bucket refueling.

NeoForgeClient and serverAll rights reserved1.21.1

What it does

The addon adds a Smart Diesel Engine that outputs kinetic power to Create machinery. Its speed is set with the scroll wheel, from -256 to 256 RPM, and scrolling into negative values reverses the rotation, so no gearshift or transmission setup is needed. The control behaves like a Creative Motor.

Refueling is done by hand: right-clicking the generator with a bucket of valid fuel fills it, so pipes, pumps and piping are not required to start the engine. Valid fuels named by the author are Biodiesel, Ethanol and Plant Oil. The addon works alongside Create Diesel Generators, which supplies the diesel generator it extends, and it requires Create and Create Diesel Generators to run.

The addon is for NeoForge on Minecraft 1.21.1 only. Servers that run it need every player to install it too. It is released under All rights reserved and is not open source. The latest file is 1.21.1 for 1.21.1, published on 2026-07-19.

Key features

  1. Speed direction control

    The scroll wheel sets the engine's rotation speed between -256 and 256 RPM, with negative values reversing direction.

  2. Smart Diesel Engine block

    A new engine block that gives the player a fixed, adjustable kinetic output instead of a standard generator's output.

  3. Manual bucket refueling

    Right-clicking the engine with a bucket of valid fuel refills it without any pumps or pipes.

  4. Compatible fuel types

    Biodiesel, Ethanol and Plant Oil are accepted as fuel, as listed by the author.

How it compares

Full comparison

Create Diesel Compat (IE Diesel Generator) is server-side only, under the MIT License, and not open source, so only the server needs it; it covers 1.21.1. Diesel Generators: Oil Info is client and server, under the MIT License, also for 1.21.1 and not open source. Create: Smart Diesel Generator Addon is client and server and under All rights reserved, which differs in its speed and direction control.

Only 1.21.1 is listed, with NeoForge as the sole loader.
