Proper noun
Otto cycle
The basic thermodynamic cycle of the normal four-stroke internal combustion engine: isentropic compression, constant-volume heat addition, isentropic expansion, and constant-volume heat rejection.
Comparing the two formulae it can be seen that for a given compression ratio ( r ), the ideal Otto cycle will be more efficient. Source: Internet
In contrast, the idealized Otto cycle of a gasoline engine approximates a constant volume process during that phase. Source: Internet
Other cycles, such as the Otto cycle, Diesel cycle and Brayton cycle, can be analyzed from the standpoint of the Carnot cycle. Source: Internet
However ammonia cannot be easily used in existing Otto cycle engines because of its very narrow flammability range and there are also other barriers to widespread automobile usage. Source: Internet
Furthermore, the ideal Otto cycle formula stated above does not include throttling losses, which do not apply to diesel engines. Source: Internet
The Otto cycle by comparison has both the heat addition and rejection at constant volume. Source: Internet
