Rotary Engine Delivers 75 Percent Thermal efficiency

A new rotary engine design delivers amazing efficiency. By going back to basic thermodynamics, LiquidPiston has developed an engine with a very high compression ratio that lets the fuel-air mixture burn completely at a constant volume. Then it is allowed to expand to near-atmospheric pressure. The result is a quiet diesel engine that does not need a muffler. And it doesn't need elaborate cooling because there isn't a great deal of waste heat.
