Emission Control Systems
158
Information
The EPA requires that motorcycles built after
January 1, 1983 comply with applicable noise
emission standards for one year or 3,730 miles
(6,000 km) after the time of purchase when
operated and maintained according to the
instructions provided.
The exhaust emission control system includes
the following components that should not need
adjustment, although periodic inspection by
your dealer is recommended.
❙
PGM-FI System
The PGM-FI (programmed fuel injection) system
uses sequential multiport fuel injection, and is
comprised of air intake, engine control, fuel
control, and exhaust control subsystems.
The engine control module (ECM) uses sensors
to determine how much air enters the engine,
and then controls how much fuel to inject.
❙
Ignition Timing Control System
The ignition timing control system adjusts the
ignition timing to reduce the amount of HC,
CO, and NOx produced.
❙
Secondary Air Injection System
The secondary air injection system adds filtered
air into the exhaust gas to help improve
emission control performance.
❙
Catalytic Converters
The exhaust system contains one or more
catalytic converters. Catalytic converters use a
catalyst to convert most of the harmful exhaust
gas compounds into harmless compounds.
