What does UFI stand for in fuel injection terminology?

In fuel injection terminology, UFI stands for Unit Fuel Injector. This term refers to a specific type of fuel injection system where each cylinder has its own fuel injector integrated with a pump, allowing for precise fuel delivery directly to the combustion chamber. The Unit Fuel Injector is particularly advantageous in diesel engines, as it enables better fuel atomization and efficient combustion, leading to improved performance and reduced emissions.

Understanding the function of a Unit Fuel Injector is crucial for maintaining and troubleshooting fuel systems in marine engines, especially in maritime applications where engine performance and reliability are vital. Other terms, while related, do not accurately describe this specific type of fuel injection system, focusing instead on different concepts or components associated with fuel delivery.
