Fuel Injector

Fuel Injector:




The fuel injection system on the DOHC 2.2L engine utilizes sequential fuel injection in which the PCM independently controls each fuel injector. The PCM grounds each fuel injector circuit for a certain length of time based on engine operating parameters. The fuel control system is designed to maintain a 14.7 to 1 air/fuel ratio under all engine running conditions except power enrichment (heavy acceleration/heavy engine load), deceleration and cold engine startup. The PCM can turn fuel injectors Off during deceleration, misfire diagnostics and traction control.
