Fuel Injection System - Multi-Point: Description

The Electronic Fuel injection (EFI) system is a pulsed time, speed density, fuel injection system. Fuel is metered into intake air stream, according to engine demand, through injectors mounted on a tuned intake manifold.

An on-board Electronic Engine Control (EEC-IV) module receives input from various engine sensors to compute required fuel flow necessary to maintain correct air/fuel ratio throughout engine RPM range.
