How this entity was disambiguated
This entity first appeared as the object of triple T15944258 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Otto cycle Context triple: [Brayton cycle, relatedTo, Otto cycle]
-
A.
Brayton cycle
The Brayton cycle is a thermodynamic cycle commonly used in gas turbine engines, where air is compressed, mixed with fuel and combusted, and then expanded through a turbine to produce work.
-
B.
Carnot cycle
The Carnot cycle is an idealized thermodynamic cycle that defines the maximum possible efficiency any heat engine can achieve when operating between two temperature reservoirs.
-
C.
Otto engine
The Otto engine is a four-stroke internal combustion engine that became the standard power source for early automobiles and many modern gasoline-powered machines.
-
D.
Carnot engine
A Carnot engine is an idealized heat engine that operates on a reversible Carnot cycle between two thermal reservoirs and represents the maximum possible efficiency any heat engine can achieve.
-
E.
Rankine cycle
The Rankine cycle is a thermodynamic power cycle that converts heat into mechanical work using phase changes of a working fluid, forming the basis of most steam power plants.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
