Like the steam engine, the Stirling engine is traditionally classified as an external combustion engine, as all heat transfers to and from the working fluid take place through a solid boundary (heat exchanger) thus isolating the combustion process and any contaminants it may produce from the working parts of the engine.
It was originally developed around 1900 for the twin-cylinder Lanchester car engine where it allowed perfect balancing of the inertial forces on both pistons. A current example of its use is on beta type-Stirling engines; the drive's complexity and tight tolerances, causing a high cost of manufacture, is a hurdle for the widespread usage of this drive.
[10] However, progress was achieved with equal-power spark-ignition engines since 1977, and the Corporate Average Fuel Economy (CAFE) requirements that were to be achieved by automobiles sold in the U.S. were being increased. [11] Moreover, the Stirling engine design continued to exhibit a shortfall in fuel efficiency [11] There were also two ...

Typical four-drum form Brick enclosure of a Stirling boiler in Queensland, Australia, originally fired on sugarcane bagasse. Chimney is to the right. Stirling boilers are one of the larger arrangements for a water-tube boiler: acceptable for stationary use, but impractical for mobile use, except for large ships with modest power requirements.
He is the maker of small Stirling Engines, "flame eater", steam engines and other types of small practical heat engines. Ridders gives free plans for building his motors and offers advice with his experience in various places on the web. After years of stagnation, once shown working models and the simplicity of the design, companies began to ...
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]
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]
