What Does PFI Stand For?

PFI stands for Port Fuel Injection

Port Fuel Injection (PFI) is an advanced fuel delivery system used in internal combustion engines, where fuel is injected into the intake manifold ports, allowing for improved atomization and mixing with air before entering the combustion chamber. This technology enhances engine efficiency, reduces emissions, and optimizes combustion performance by ensuring precise control of the fuel-air mixture, contributing to better throttle response and overall driving experience. PFI systems are commonly found in gasoline engines and are crucial for meeting modern emission standards while delivering reliable power.
