Watching the videos on the new 6.7L PSD, and more specifically the one that contrasts the change in engine noise kind of got me thinking. I am aware that the 6.0L uses Hydraulic Electronic Unit Injection vs Piezo Electric injectors on the 6.4 and 6.7.
1) Can somebody explain the differences in injection strategy in terms of the number of injections per cycle between the 6.4 and the 6.0?
2) Have there been any changes to that strategy in the 6.0 from year to year with factory updates?
From what I seem to remember the 6.0 utilizes 2 shots/cycle(pilot and main injection) when the engine is above a given temperature due to the oil viscosity.
