The systems forcontrollingemissionsto the
atmosphere require regular checking and
adjustment at the intervals specified in the
service program.
In addition to meeting the exhaust emission
regulations and thereby helping to keep the
environmentclean,acorrectlytunedengine
will also give maximum fuel economy.
Saab Trionic engine management
system
Saab cars imported into the United States
and Canada meet all applicable emission
control standards. The engine family and
appropriate tune-up specifications are iden-
tified on a label affixed to the left front inner
fender.
These engine families meet applicable EPA
Federal Standards, California State Stan-
dardsandCanadianFederalStandardsand
are equipped with the following systems:
The Saab Trionic engine management
system is a unique Saab development that
combinessequentialmultiportfuelinjection,
electronic distributorless ignition and turbo-
charger boost pressure control into one sys-
tem.
The Trionic engine control module (ECM)
monitors many different engine parameters
such as:
•
•
•
•
Sequentialmultiport fuelinjectionsystem.
Three way catalytic converter.
Crankcase emissions control system.
Evaporative emission system.
• Intake manifold pressure.
• Intake air temperature.
• Crankshaft position.
• Engine coolant temperature.
•
•
Throttle position.
The oxygen content of the exhaust gases.
The ECM receives information regarding
engine knocking from a sophisticated feed-
back function in the ignition discharge unit.
By processing all of this information, the Tri-
onic system can control fuel injector open-
ing duration, ignition timing and turbo-
charger boost pressure to provide excellent
engine performance while maintaining low
emissions and fuel consumption.
