1. What is the function of a scavenging air receiver?
The scavenging air receiver collects and stores scavenging air for diesel engines.
2. What is the purpose of a jacket cooling system?
The jacket cooling system is designed to cool the engine cylinder and prevent overheating.
3. What is the meaning of the term ‘Sulphur content’ in marine diesel engines?
Sulphur content in marine diesel engines refers to the level of sulphur in the fuel used. High levels of sulphur in fuel can lead to harmful emissions.
4. What is a shaft generator on board a ship?
A shaft generator is a type of generator that is driven by the main engine of the ship. It is used to generate electrical power while the ship is underway.
5. What is the purpose of a ballast water treatment system?
The purpose of a ballast water treatment system is to remove or kill organisms that may be present in the ballast water of a ship. This is important to prevent the spread of invasive species and protect marine ecosystems.
6. What is the function of a turbocharger on a marine diesel engine?
A turbocharger is used to increase the air pressure in the cylinders of a diesel engine, which leads to better combustion and increased power output.
7. What is the role of a purifier in a marine engine?
A purifier is used to separate oil and water from fuel. This helps to ensure that only clean fuel is used in the engine and reduces the risk of engine damage.
8. Define the term ‘reversing gear’ in a marine engine.
A reversing gear is a device that allows the direction of rotation of a marine engine to be reversed, enabling the ship to move forward or backward.
9. What is a ‘fresh water generator’ and what is its function on a ship?
A fresh water generator is a device that is used to convert seawater into potable water for use on board a ship. This is important to ensure that there is enough fresh water available for drinking, cooking, and other uses.
10. What is the purpose of a cylinder liner in a marine diesel engine?
A cylinder liner is a sleeve that is inserted into the cylinder of a diesel engine. It helps to protect the cylinder from wear and corrosion, and also improves heat transfer between the cylinder and cooling system.
