Diesel injection pump, general information: Notes
The diesel injection pump for the AAZ engine is equipped with boost pressure enrichment (BPE) as well as load-dependent injection timing.
Load-dependent injection timing function is integrated with the injection pump. It adjusts the starting point of fuel injection based on engine load. This adjustment helps achieve smoother running. It is switched off at engine speeds above approx. 2800 RPM.
Load-dependent injection timing is switched off by activation of the Injection Start Positioner (N165) -1- on the injection pump, which is activated by the Automatic Glow Time Control Module -J179-.
