The purse key replaces the function of the workshop key.IHKAThe location of the operating buttons on the IHKA control unit has been changed. The func-tionality remains the same.Drive TrainEnginesSULEVM56 SULEV (SuperUltraLowEmissionVehicle) is available on a limited (by state) basis in theE46/2, E46/3 and E46/4.SULEV models (E46 sedan, coupe and sportwagon all with automatic only) will be sold inCalifornia, New York and Massachusetts as 2003 models and in Vermont starting in 2004model year.4E46FLIn addition these vehicles are certified as PZEV (Partial Zero Emissions Vehicles).PZEV regulations include:••••Vehicles must meet SULEV tailpipe emissions standard (approx. 1/5 of ULEV standards)Vehicles conform to Zero Evaporative EmissionsVehicles subject to extended OBD regulations.Emission relevant components warrantied for 15 years or 150,000 milesM56 EngineThe following components are used to achieve SULEV and Zero Evaporative Emissionrequirements:•••••••••••Pistons Revised to change spark travel pathCatalytic Converters Ceramic carriers with high cell density for better “Warm Up”ControlOxygen Sensors Planar wide band O2 sensors in front of the catsVanos Positioning changed during start up for improved start up and emissionsFuel Pump Control Revised with raised pressure and more accurate flow controlFuel Injectors New design for improved fuel flow and higher working pressureFuel System All metal fuel system components made of stainless steelAir Intake System Revised to block HC escapeCrankcase Ventilation RevisedSecondary Air System Mass air flow sensor to monitor secondary air flowCooling System Revised to reduce Ozone levelsCatalytic ConvertersThe catalysts attached in direct proximity tothe engine and are equipped with ceramic(s)carriers in high cell density technology. Theseconverters reach operating temperature fasterand offer quicker control of exhaust emissions.Vehicles are also equipped with dual down-stream converters.Oxygen SensorsThe M56 engine uses four Oxygen sensors,two planar broadband sensors upstream ofthe converter and two sensors downstream.The planar broadband sensor reach operatingtemperature very fast and are able to effect fuelmixtures in approximately 5 seconds.5E46FL [ Pobierz całość w formacie PDF ]
