Digital Diesel Electronics

Fine tuning for fuel injection - the Digital Diesel Electronics (DDE) system manages all engine functions in BMW diesel models. This saves fuel, ensures you enjoy smooth, cultivated performance and helps reduce exhaust emissions, thereby minimising your BMW’s impact on the environment.

Common rail fuel injection in BMW diesel engines combines greater fuel efficiency, lower emissions, improved engine sound and significantly smoother running. Digital Diesel Electronics (DDE) supports these important advantages.

DDE is a system that monitors the position of the accelerator and the driver’s application of pressure to determine exactly when fuel injection is to start, as well as the volume of fuel supplied and charge pressure. This ensures optimum fine tuning for the relevant engine responses under all running conditions. The result of this micromanagement is even greater economy, improved smoothness and a reduction of harmful emissions. 

The DDE system is also responsible for speed regulation, and gives the electronic immobiliser clearance for ignition when the correct key code has been supplied.
