What does SFI mean?

SFI is a type of multipoint fuel injection system in which each injection valve will open just before the cylinder intake valve opens. The individual injections work by themselves because they are fired individually. Other multi-port systems will fire all the injectors in a group no matter if the cylinder is ready or not. But the SFI has many advantages, direct injection is quickly becoming the system of choice and it is replacing the SEFI systems.
