An other aspect that the software Crankshaft Balance Design calculates is
the fluctuation of the crankshaft speed during the cycle,
in fact, the energy developed by the combustion is concentrated in a
one part of the cycle and is redistributed according to the inertia of the crankshaft
and the elements connected to it.
This determines a
different crankshaft speed and consequently a different duration of
phases, therefore the inertia, especially at low loads, can also influence
the fluid dynamics of the engine and therefore modify the performance.
The software calculates then the duration of the phases in function of the fluctuation of the crankshaft speed and also shows how is modified the
duration between the stroke of compression and expansion.
