Other devices which use linear alternators to generate electricity include the free-piston linear generator, an internal combustion engine, and the free-piston Stirling engine, an external combustion engine.
12.
The external combustion engines and boilers on steam locomotives were large, heavy and time and labor-intensive to maintain, and the days of steam for high speed were numbered.
13.
It relies on a complex design known as an external combustion engine and can operate much more efficiently than the internal combustion engines that power cars, for example.
14.
In 1816, Robert Stirling, a multitalented minister of the Church of Scotland, patented a simple design for an external combustion engine; unfortunately, it proved too costly to mass produce.
15.
External combustion engines can use almost anything that burns as fuel whilst internal combustion engines and rocket engines are tailor built to burn a specific fuel, typically gasoline, diesel or ethanol.
16.
Mark 60 CAPTOR mines begin being deployed in 1979 . It is powered by a two-speed, reciprocating external combustion engine, and has a range of 8, 000 yards at 28 knots.
17.
A "'timing or valve chest "'is a compartment on an internal or external combustion engine ( e . g . gasoline or steam engine ) which provides access to the tappets and valves.
18.
Cycles that model external combustion engines include the Brayton cycle, which models gas turbines, the Rankine cycle, which models steam turbines, the Stirling cycle, which models hot air engines, and the Ericsson cycle, which also models hot air engines.
19.
Another common use is to provide a relatively safe ( see disadvantages below ) heat source for model steam engines, such as those manufactured by Wilesco and Mamod, and other external combustion engines such as Stirling engines and pop pop boats.
20.
Engines of similar ( or even identical ) configuration and operation may use a supply of heat from other sources such as nuclear, solar, geothermal or exothermic reactions not involving combustion; but are not then strictly classed as external combustion engines, but as external thermal engines.
