Also, using a ported design rather than conventional poppet valves makes for extraordinarily quiet operation,” stated LiquidPiston co-founder and Chief Technology Officer Nikolay Shkolnik.
“Imagine what you could do with a light weight, quiet, 20 HP diesel engine the size of a shoe box,” said Edward Richards, CEO of LiquidPiston. “The company is working with industry partners to develop applications ranging from Auxiliary Power Units for long haul trucks, to field generators for the military, lawn and garden equipment, and range extenders for series hybrid electric vehicles. A number of companies are pursuing new engine designs, but unless the underlying thermodynamics are improved, those engines will only offer incremental advantages over existing technology. The High Efficiency Hybrid Cycle sets a new bar for efficiency and puts engine designs on a new efficiency learning curve. Our running prototype indicates it will be feasible to provide the disruptive improvement in fuel efficiency that is so critical to our economy and environment.”
