A Stirling engine cannot start instantly; it literally needs to "warm up". This is true of all external combustion engines, but the warm up time may be longer for Stirlings than for others of this type such as steam engines. Stirling engines are best used as constant speed engines.
An external combustion engine (EC engine) is a reciprocating heat engine where a working fluid, contained internally, is heated by combustion in an external source, through the engine wall or a heat exchanger. The fluid then, by expanding and acting on the mechanism of the engine, produces motion and usable work. [1]
A Stirling engine eliminates the need for water anywhere in the cycle. This would have advantages for nuclear installations in dry regions. United States government labs have developed a modern Stirling engine design known as the Stirling radioisotope generator for use in space exploration. It is designed to generate electricity for deep space ...
In mechanical engineering, the Beale number is a parameter that characterizes the performance of Stirling engines. [1] It is often used to estimate the power output of a Stirling engine design. For engines operating with a high temperature differential, typical values for the Beale number are in the range 0.11−0.15; where a larger number ...

In 1842, James Stirling, the brother of Robert, build the famous Dundee Stirling Engine. This one at least lasted 2–3 years but then was discontinued due to improper technical contrivances. Hot air engines is a story of trials and errors, and it took another 20 years before hot air engines could be used on an industrial scale.

A Fluidyne engine is an alpha or gamma type Stirling engine with one or more liquid pistons. It contains a working gas (often air), and either two liquid pistons or one liquid piston and a displacer. [1] The engine was invented in 1969. [2] The engine was patented in 1973 by the United Kingdom Atomic Energy Authority. [3] [2]
