CPC Definition - Subclass F02G
This place covers:
Hot-gas or combustion product positive-displacement engine plants and use of waste heat of combustion engines, not otherwise provided for.
This place covers:
Hot gas positive-displacement engine plants, e.g. Stirling engines.
Attention is drawn to the following places, which may be of interest for search:
Positive-displacement engine plants characterised by the working gas being generated by combustion in the plant | |
Steam engine plants, special vapour plants, plants operating on either hot gas or combustion-product gases together with other fluid | |
Gas-turbine plants | |
Jet-propulsion plants |
In this place, the following terms or expressions are used with the meaning indicated:
Plant | An engine together with such additional apparatus as is necessary to run the engine. For example, a steam engine plant includes a steam engine and means for generating the steam. |
This place covers:
"Stirling" type engines.
Stirling engines are divided in three types:
- Alpha.
Pairs of sealed pistons in separate cylinders (no displacer).
a. with parallel pistons.
b. with cylinders opposed in line.
c. with cylinders opposed parallel.
- Beta.
Piston - displacer arrangement: piston and displacer in the same
cylinder. Cylinder has a hot end and a cool end:
- Gamma.
Piston - displacer arrangement : piston and displacer in separate cylinders: 
This place covers:
Stirling type engine having at least two working members, e.g. pistons, delivering power output. E.g. Vuilleumier cycle:
This place covers:
Positive-displacement engine plants characterised by the working gas being generated by combustion in the plant, e.g. positive displacement engine plants with external combustion:
In this place, the following terms or expressions are used with the meaning indicated:
Plant | An engine together with such additional apparatus as is necessary to run the engine. For example, a steam engine plant includes a steam engine and means for generating the steam. |
This place covers:
Profiting from waste heat of combustion engines, not otherwise provided for, e.g. converting heat directly to electric power via a thermoelectric generator using the Seebeck effect or converting the waste heat to mechanical power using a Rankine cycle.
