204 Car care By processing all of this information, the ME9 system can control fuel injector opening duration, ignition timing, intake camshaft phasing and turbocharger boost pressure to provide excellent engine performance while maintaining low emissions and fuel consumption. NOTICE The Trionic engine management system continuously monitors the operation of these systems and has on-board diagnostic capabilities (OBD II). If the Engine malfunction (CHECK ENGINE) light in the main instrument illuminates, the Trionic ECM has detected a problem. The car will continue to operate, but performance may be diminished. You should have your car checked by a workshop as soon as possible. We recommend that you contact a Saab dealer. ORVR (Onboard Refueling Vapor Recovery) All hydrocarbons formed when refueling will be recovered by the car and not released into the atmosphere. The hydrocarbons are absorbed in an evaporative emission canister. When the engine is subsequently started, the evaporative emission canister is gradually purged as air is sucked into it through a shut-off valve. The hydrocarbon/air mixture passes through the evap canister purge valve and into the engine where it is burned. "Refueling", see page 157. When refueling, make sure you screw the filler cap on and keep turning until it has clicked 3 times.

Bosch ME9 engine management system, V6 engine The Bosch ME9 engine management system is a system that combines sequential multiport fuel injection, electronic distributorless ignition and turbocharger boost pressure control into one system and intake camshaft phasing control. The ME9 engine control module (ECM) monitors many different engine parameters such as Charge air pressure. Intake air temperature. Crankshaft position. Engine coolant temperature. Throttle position. The oxygen content of the exhaust gases.
