Auxiliary Engine – Definition and Pronunciation
What is Auxiliary Engine?
An auxiliary engine on a sailboat is a small engine that is intended for intermittent use, such as anchoring, going in and out of harbors, and making a course in a flat calm. On an auxiliary sailboat the prime means of propulsion is intended to be the sails, not the engine.
An auxiliary engine on a big vessel is a smaller engine used primarily for powering onboard equipment and systems, such as generators, pumps, winches, and refrigeration units, rather than for propelling the ship. These engines ensure the continuous operation of essential systems, especially when the main engine is not running or when additional power is required.
Examples of Auxiliary Engine
The true sailboat auxiliary engine is designed to power in and out of anchorages or when conditions are so light that significant progress cannot be made under sail alone.
From “Self-Survey Criteria for the Engine and Electrical Systems”.
Lower electrical power demand allows installation of less auxiliary engine power.
From “Gas and diesel low-pressure two-stroke engine (X-DF)”.
The second mechanic is responsible for the main and auxiliary engines, including emergency diesel generators (EDG), as well as all associated technical equipment. He is responsible for shafting, including gearboxes and release couplings, stern tube devices, propulsors and the mechanical part of the steering device.
