Leerlauf regelt das EML, Zitat:
The Electronic Throttle Control System (EML) regulates the operation of the throttle valve(s). The scope of EML design on BMW engines provides:
• Throttle valve positioning for optimum starting
• Precise idle speed regulation without the use of an external idle control valve/circuit
• Progressive throttle opening curves matched to the driving program (with EGS/AGS interface)
• Cruise control operation without additional control modules and linkages
• Automatic synchronization of the throttles (airflow balancing) for two independent banks,throughout the entire engine speed range (M70, S70, M73 engines only)
• Intake air volume control for ASC/DSC (Automatic Slip Control/Directional Stability Control)systems
• Maximum road speed limiting
• Emergency “Failsafe” operation in the event of component failures
The EML control module is a link in the total scope of Engine Management Control. The EML is interfaced with other control modules to complete the management system, which includes:
• ECM(s) - Except E46 (EML integrated in MS42.0 ECM)
• EGS/AGS
• ABS/ASC
The main components of the EML system are:
• Accelerator pedal position sensor (PWG)
• Accelerator pedal position sensor (driver’s wish sensor - integrated in throttle housing, E46 MS42.0)
• Throttle valve assembly/assemblies with electronic control motor(s) - DK/MDK
• EML control module (MS42.0 ECM - E46)
