16.3 Mass moments of inertia
The mass-moments of inertia of the main engines (including flywheel) are typically as follows:
J [kgm²] Engine
500...560 W 6L32
520...600 W 7L32
520...650 W 8L32
650...690 W 9L32
730...810 W 12V32
830...900 W 16V32
980...1010 W 18V32
16.4 Air borne noise
The airborne noise of the engine is measured as a sound power level according to ISO 9614-2.
The results are presented with A-weighing in octave bands, reference level 1 pW. Two values
are given; a minimum value and a 90% value. The minimum value is the lowest measured
noise level. The 90% value indicates that 90% of all measured noise levels are below this
value.
