Use of marine auxiliary engine

A marine auxiliary engine is a secondary engine that provides power to a ship’s systems and equipment.

The purpose of a marine auxiliary engine is to provide electrical power and hydraulic power for the ship’s various systems and equipment. These systems can include:

1. Electrical power generation:

Auxiliary engines are used to generate electricity for lighting, communication, navigation, and other essential systems.

2. Pumping systems:

Auxiliary engines are also used to power the various pumps on the ship, including bilge pumps, fire pumps, and ballast pumps.

3. HVAC systems:

Auxiliary engines provide power to the heating, ventilation, and air conditioning (HVAC) systems on the ship.

Why do we use four stroke engines on ships as an auxiliary engine?

Four-stroke engines are commonly used as auxiliary engines on ships instead of two-stroke engines for several reasons:

1. Flexibility:

Four-stroke engines are more flexible in terms of their power output and can be adapted to different power requirements. This makes them suitable for use as auxiliary engines on ships, where power demands can vary widely.

2. Lower Operating Costs:

Four-stroke engines are generally more fuel efficient than two-stroke engines at low and medium loads, which is where auxiliary engines typically operate. This means that they can help to reduce the operating costs of a ship.
