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 accepts inputs from various engine sensors to compute required fuel flow necessary to maintain correct air/fuel ratio throughout engine RPM range.
The EEC-IV module sends a command to injectors to meter approximate quantity of fuel. System will automatically sense and compensate for changes in altitude and will permit push-starting vehicle (manual transmissions only).
