Auxiliary engine is a term used in the maritime industry to refer to any engine that is not the vessel's main propulsion system. This term is spelled /ɔːɡˈzɪljəri endʒɪn/ in IPA phonetic transcription. The first syllable is pronounced like "or" without the r, followed by "gzil" which rhymes with "fizzle". The stress falls on the second syllable, pronounced like "liary". The final syllable is pronounced like "engine", with the stress again falling on the second syllable.
An auxiliary engine refers to a secondary or additional power source used to assist the main engine or provide supplementary power for machinery or systems. Typically found in vehicles, ships, airplanes, or industrial settings, an auxiliary engine is designed to serve as a backup or support system to ensure continuous operation or to fulfill specific functions.
In the context of transportation, an auxiliary engine typically functions when the primary engine is not operating, such as during startup, idle modes, or when additional power is required for specific purposes. These engines can be used to power systems like air conditioning, heating, electrical generators, hydraulic pumps, or winches. They are often smaller, more lightweight, and consume less fuel compared to the primary engine.
In marine vessels, an auxiliary engine is employed to generate power for onboard functions such as navigation, lighting, or communication, especially during periods of mooring, anchoring, or when the main engine is not in operation. Moreover, these engines are crucial for maneuvering a ship in ports or harbors, aiding in steering and maintaining an appropriate heading.
Within the industrial sector, auxiliary engines are commonly integrated into machinery or equipment to provide additional power or for specific purposes that require an independent power source. This ensures uninterrupted operation and allows versatility in demanding applications.
Overall, an auxiliary engine acts as a reliable backup system, providing auxiliary or supplementary power when the primary engine is not in use or requires assistance. Its capability to deliver reliable support when needed makes it a vital component in various domains, ensuring steady operation and functionality.
The word "auxiliary" originates from the Latin word "auxiliarius", which means "helping" or "assisting". It was formed from the root "auxilium", meaning "aid" or "support".
The term "engine" has its roots in the Latin word "ingenium", which translates to "innate quality", "talent", or "ability". It eventually came to refer to machines or devices that convert energy into mechanical work.
Therefore, the etymology of the phrase "auxiliary engine" combines the idea of something that assists or aids (auxiliary) with the concept of a machine or device that generates power or performs work (engine).
