Cylinder Bank Synchronization
The throttle valves are synchronized automatically on the EML IIIs system. This ensures that both cylinder banks receive the same air charge and creates a smooth running engine. The synchronization takes place at an idle during the purge system shut off time. The synchronization process last approx. 100 seconds.
The total conditions for synchronization to take place are:
- Idling
- Engine speed between 560 - 720 RPM
- Throttle valve stops recognized (DK idle position)
- Load difference side-to-side no more than .04 to 10 %
- No faults in DME/EML control modules
- Purge system shut down
The EML control module processes the load signals from the two DME control modules. If a difference exists, the EML will adjust the DK motors to achieve equal air throughput on both banks. If the load difference is greater than 10%, the synchronization will not take place and a fault is stored in the memory.
