The possibility of replacing the relatively fuel inefficient gas turbine for certain commercial applications with the more efficient reciprocating engine. A problem for both marine and power generation reciprocating engines is the short duration of allowable full load operation imposed by durability...

For industrial and commercial applications, the cost of fuel typically exceeds the initial cost of the engine by a large factor. For example, a 3% reduction in fuel consumption for a 500 hp industrial diesel operating at rated power and 8,000 hours per year represents over $7,500 in annual savings (...

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 en...

Detailed theoretical and modeling analysis combined with SVE data predicts fuel consumption savings through piston friction reduction to be in the range of 3.0-4.5% at full load (stationary engine applications), up to 9% under urban traffic driving conditions (Class 7 or 8 truck), and 27% at idle (v...

Sleeve Valve Engines (similar technology in terms of piston lubrication) were built in very large numbers and used successfully in WWII warplanes. While SVE's demonstrated 10 times lower cylinder wear rate and established records for fuel efficiency, they would not meet today's stringent emission st...
