Friction reduction accounts for 6% efficiency increase
It's unique to add components to an engine mechanism and end up with lower friction.
It's really the case though with the GoEngine technology where the eccentric bearing and the conrod bigend bearing both run at half the crankshaft speed.

Two bearings have less friction as one bearing running at double speed
Another advantage reducing friction is realised by the weight reduction of 40% of the one part conrods.
