Robert Stirling patented the first practical example of a closed-cycle hot air engine in 1816, and it was suggested by Fleeming Jenkin as early as 1884 that all such engines should therefore generically be called Stirling engines. This naming proposal found little favour, and the various types on the market continued to be known by the name of ...
Since the Stirling is an external combustion engine, the exhaust has virtually no odor and pollution levels can be made very low. Another hybrid electric car GM experimented with in 1969 was the XP-883 which featured a similar, but reversed drive line to the Stir-Lec I (using front-wheel drive , with a front-mounted motor and engine, along with ...
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 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]
NASA patented a type of solar-powered Stirling engine on August 3, 1976. It used solar energy to pump water from a river, lake, or stream. [1] The purpose of this apparatus is to “provide a low-cost, low-technology pump having particular utility in irrigation systems employed in underdeveloped arid regions of the earth…[using] the basic principles of the Stirling heat engine“.
