Stirling Engine : A Beginners Guide

Stirling Engine : A Beginners Guide ->->->->

Last year I was an IB student in the MYP program. At the end of the year we had to do a research project on something that interests us. Doing some research on the internet, I came across something called a stirling engine."So, what the heck is a stirling engine" You may ask. Well when I first heard of it I thought of a chrome plated V8 internal combustion engine. However, according to a quick look at Wikipedia, "A Stirling engine is a closed-cycle regenerative heat engine with a permanently gaseous working fluid". Stirling engines happen to be one of the more efficient engines invented and can even act as a heat pump if manually turned. With the world taking a new focus on "green" energy, the stirling engine is making a comeback, being used in generators on small scales in remote areas and in larger scales, contributing to power grids.The next few steps will get more into the history and applications of stirling engines.If history and long boring back stories aren't your thing skip over to the build at Step 4.

Stirling engines are now starting to gain popularity for it's high fuel efficiency and being relatively quiet while running. They are used in some generators as they can be powered by any heat source like solar or gas/wood flame. There are larger scale solar farms in Arizona that produce power using stirling engines.

In the 90's, NASA was experimenting with putting a stirling engine into a truck. They could burn any fuel that they wanted including diesel and even jet fuel. They eventually scrapped the idea for research into its uses as a stationary generator.

There are a few basic parts to the kind of stirling engine we are going to build. There is the flywheel, power piston and displacer. The power piston is what captures the expansion and contraction of the working fluid. The displacer moves air inside the engine to heat it up or cool it off. The flywheel keeps momentum and turns the engine to the next stage while the power piston isn't pushing or on the pull stroke when it is weaker.

"An Introduction to Low Temperature Differential Stirling Engines" it is wonderful intro and how to guide. Too bad it seems to be out of print. This configuration of engine was looked at, among other uses, as a CPU cooler for computers.

Stirling engines (formerly referred to as steam engines) are the second tier of engine. They use cobblestone instead of wood or iron so are still cheaper than the Combustion Engine. Previously, it had been stated that Stirling Engines would not blow up and would simply stop operating when heated too much. In recent versions, the Stirling Engine will only explode if energy produced is not being removed from the engine. Stirling engines will explode at 250.0C. Note that the flame gauge on the Steam/Stirling Engine GUI does NOT indicate if it has any energy to run or not, but rather if there is still fuel being added to build up heat. In other words, the stirling engine continues to run quite a while after the instant the flame gauge empties and there is no more fuel in the slot to burn (unlike Vanilla machines).

The stirling engine runs on burning items and so needs refuelling to continue operation. Burnable items include lava buckets (which are consumed in 2.2.10), coal, charcoal, wood, planks, sticks, saplings, crafting tables, chests and bookcases--basically it will burn everything a normal furnace will burn, including Cactus and Sugar Cane (Though from 4.1.2 on, cactus and sugar canes will not work within this engine). The stirling engine also needs a redstone signal or pulse to run. Fuel items can be pumped in via a transport pipe for convenience.
