RSET Inc. is developing the rotation liner engine(RLE), a unique lubrication concept for traditional internal combustion engines. The RLE incorporates a rotation liner between the piston and the engine block, exploiting the well proven piston and piston ring advantage of the historic sleeve valve engine ( a total of 200 million horsepower of SVE's were built during WW2) and applying it to the modern exhaust-emission-driven reciprocating engine. The RLE improves efficiency, decreases pollutants, increases durability, and has applications thought 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 prototype.
