Exhaust Emission Control System
The exhaust emission control system
includes a secondary air supply system,
and a PGM-FI system. (California only:
also includes an oxidation catalytic
converter.)
No adjustment to these systems should be
made although periodic inspection of the
components is recommended.
Emission Control Systems
PGM-FI System
The PGM-FI system uses dual sequential
fuel injection. It has four subsystems: Air
Intake, Engine Control, Fuel Control, and
Exhaust Control.
The Engine Control Module (ECM) uses
various sensors to determine how much air
is going into the engine. It then controls
how much fuel to inject under all
operating conditions.
Ignition Timing Control System
The system constantly adjusts the ignition
timing, reducing the amount of HC, CO
and NOx produced.
