Mechanical Fuel Injection
Mechanical Fuel Injection (MFI) is a fuel delivery system that uses mechanical components, such as pumps, valves, and nozzles, to precisely meter and inject fuel into an engine's intake manifold or cylinders without electronic control. It was widely used in automotive and aviation applications before the advent of electronic fuel injection (EFI), offering improved performance and fuel efficiency over carburetors. The system operates based on engine speed, load, and other mechanical inputs to adjust fuel delivery.
Developers should learn about Mechanical Fuel Injection when working on legacy automotive systems, restoration projects, or specialized high-performance engines where mechanical reliability and simplicity are prioritized over electronic complexity. It is particularly relevant in motorsports, vintage vehicle maintenance, and educational contexts to understand the evolution of fuel injection technology and mechanical engineering principles.
