6L V6 gasoline engine and evaluate the wear of the piston rings and piston ring/liner interface with a market representative fuel containing a generic additive using radioactive tracer technology (RATT) and white light interferometry (WLI).
To this end, the piston rings may achieve better sealing characteristics within a low distorted cylinder bore, and, for unchanged sealing demand, the engine friction losses could be reduced by decreasing the pretightening force on piston rings.
Hence, the piston rings are lubricated by oil, the film thickness of which results in low friction and reduced wear.

The suspension resulted from both the natural disaster and the fact that the vehicle makers use unique piston rings, which Riken's and the clients' engineers jointly design.
Given that Riken, a major maker of piston rings, needs more time before resuming full-scale operations, it is possible that the output loss could increase, according to officials at the automakers, including Honda Motor Co.
Some of that fuel may even seep past the piston rings and into the oil.
