ECI CEC System: Operation: Notes

The ECI system is primarily an emission control system, designed to maintain ideal air/fuel ratio under all operating conditions. When an ideal ratio is maintained, the catalytic converter can control carbon monoxide (CO), hydrocarbon (HC) and oxides of nitrogen (NOx) emissions.

The ECI system consists of the following subsystems: Fuel Control, Data Sensors, Electronic Control Unit (ECU), Idle Speed Control (ISC), Emission Control, Fuel Cut-Off, catalytic converters and other related components.
