Tribo Dynamics, Inc

Tribo Dynamics has developed the rotating liner engine (RLE), a unique lubrication concept for traditional internal combustion engines. The RLE incorporates a rotating liner between the piston and the cylinder bores, exploiting the well proven piston and piston ring advantage of the historic sleeve valve engine and applying it to the modern exhaust-emission-driven reciprocating engines. The RLE technology improves mechanical efficiency, decreases pollutants, increases engine life, and has applications throughout the range of the $50B+ heavy-duty diesel market. The basic engineering assumption behind the RLE has been confirmed by preliminary results from single cylinder light-duty based RLE Alpha prototype.
