text: There are only three piston phases in a four stroke inline six and, whilst the nature of the piston motion can never result in a 3rd-order imbalance (the pistons have no oscillation at that rate), it does appear in the kinetic energy exchange between the pistons and crankshaft (mathematically because of the squaring of velocity resulting in a specific intermodulation of frequencies).
