ECI System

The Electronic Control Injection (ECI) system is a computerized emission and fuel control system. The ECI system controls engine operation and lowers exhaust emissions while maintaining good fuel economy and driveability. The Electronic Control Unit (ECU) is the foundation of the ECI system. The ECU monitors many of the related systems to constantly adjust air/fuel ratio. Air/fuel ratio control is achieved by controlling driving time of the 2 injectors installed on injection mixer. The ECI System consists of the following subsystems: Air/Fuel Ratio Control, Ignition Timing Control, Idle Speed Control (ISC), Secondary Air Control and EGR Control.

NOTE: For information on Secondary Air Control and EGR Control Systems, see appropriate articles in this section.
