Modern medium speed diesel engines normally have relatively short crankshafts with large diameter pins. How do these design features affect the reliability of crankshaft deflection readings?
The design of the crankshaft has very little effect on the readings when compared to the inaccuracies that arise due to human error.
Very short, stiff crankshafts do not deflect even when the engine is running so the readings are unaffected.
They increase the risk of inaccurate readings due to the 'stiff' shaft having very small natural sag which may therefore result in 'floating journals' in the static condition.
They reduce the risk of inaccurate readings as the large diameter pins result in a relatively heavy shaft which will reduce the risk of 'floating journals'.
