Injector Rattle Cause

[JTaylor2005]

Hi all. Had a look around today as to what causes the injector rattle. I found this very interesting. Apparently it can also cause a higher injection quantity and pre injection that is too large causing more knock/rattle. Sounds like it could be causing a large spike of cylinder pressure in the affected cylinders as well by the looks of it.

Have a look at fly specs post about 2/3rd of the way down.
