Types of Fuel Injection Systems in Marine Propulsion
Fuel injection systems in marine propulsion can be categorized into several distinct types, each tailored to specific engine requirements and operational contexts. The primary types include port fuel injection (PFI), direct fuel injection (DFI), and electronic fuel injection (EFI).
Port fuel injection operates by delivering fuel to the intake manifold, allowing it to mix with air before entering the combustion chamber. This method enhances fuel atomization, improving combustion efficiency and engine performance. It is commonly used in smaller marine engines due to its lower complexity and cost.
Direct fuel injection, on the other hand, involves injecting fuel directly into the combustion chamber under high pressure. This technique provides superior combustion control, leading to better fuel efficiency and reduced emissions, making it increasingly popular among modern marine engines.
Electronic fuel injection utilizes sensors and a control unit to optimize fuel delivery based on engine conditions.
