Harjamoottoreita

Harjamoottoreita, also known as auxiliary engines or auxiliary power units (APUs), are small, self-contained engines used to provide power and heat to various systems on aircraft, ships, and other vehicles. They are typically used when the main engine is not running or when additional power is required. Harjamoottoreita are designed to be reliable and efficient, often using a combination of fuel types such as diesel, kerosene, or even electricity. They are commonly found in military and commercial aircraft, as well as in naval vessels and some ground vehicles. The use of harjamoottoreita allows for increased flexibility and redundancy in power systems, ensuring that critical functions can continue even if the main engine fails.
