About this project
What does Mekanism Diesel Generator add?
Eight multiblock gensets, from a small inline-6 diesel to a 777-block marine two-stroke, plus a helicopter turboshaft, an aeroderivative gas turbine, a methane digester, cooling towers and the plumbing to tie them together. Every engine has its own sounds, smoke, live control panel and real fuel consumption.
At a glance
**8 multiblock engines**: inline-6, V8, V12, V16 diesels, petrol V8, turboshaft, gas turbine, marine two-stroke.
**Built from construction blocks** placed in a pattern, then **formed with one click of the wrench**. The blocks merge into a detailed model; break one piece and everything goes back to blocks.
**Real energy model**: fuel use = power / (fuel energy × efficiency). Diesel, biodiesel, petrol, kerosene, LPG, methane, ethanol, heavy fuel... each fuel has its own energy content.
**Oil and breakdowns**: engines use oil; run one dry or too hot and a piston, a rod or a pump breaks until you fit a new one. **Lubrication port** on every engine.
**Water cooling loop** behind a thermostat (hot water out at 72-75 °C), overheating protection and **cooling towers** (a small one and a hyperboloid one you can build at any size).
**Exhaust lines and stacks**: a thick diesel plume that darkens with the load. Route it into the sky, or the engine room fills with smoke and you get nausea and poison.
**Mekanism-style control panel**: tachometer, kW and temperature dials, live readings (rpm, kW, FE/t, mB/t and litres per hour), tanks, start / stop, redstone control and a hand throttle.
**Real engine sounds**: start, every power notch, ramp up / down, shutdown, with a quieter copy at the stack. **Ear defenders** for the engine room.
**Turning radiator fans**, walkways on the marine engine, detailed models in Mekanism textures.
**Process machines**: anaerobic digester (compost → methane), small fan cooling tower, block heater, heat exchanger to the Mekanism heat network, portable petrol genset.
**Mekanism pipes and cables plug straight in.** Mekanism textures and GUI style throughout.
**Ponder scenes** (Create / Ponder) for every machine.
**ComputerCraft** peripherals and **KubeJS / datapack** hooks (fuel tags, fuel energy data map).
Diesel gensets: inline-6, V8, V12, V16
V8 :

V16 :

The workhorses. The two-strokes (V12, V16) climb through six throttle notches like an EMD locomotive. The four-strokes go from idle to no load, half load and full load. The V16 has a turbocharger, a generator blower and a control cabinet.
Marine two-stroke

The giant: 8 × 12 × 20, 777 blocks, walkways and railings, 262 144 FE/t. It has no radiator: it **needs a water loop** on its cold / hot water ports, even at idle. It starts on light fuel, then switches to **heavy fuel** (heavy fuel oil, crude oil, creosote) after a minute of running. It flushes back to light fuel before stopping, like a real ship engine. Its sound is the V16's, slowed right down.
And Many more !
