20120324889 | ADVANCED UNIFLOW RANKINE ENGINE AND METHODS OF USE THEREOF - An Advanced Uniflow Rankine Engine (“AURE”) that is effective and thermodynamically efficient at higher speeds (e.g., 400-1800 rpm) and has low torque output. This allows the AURE to be compact of size without the need for a massive foundation found in prior art steam engines. The AURE includes an admission valve assembly, a cylinder head/valve gear assembly, a cylinder/piston assembly, a crank shaft assembly, an external sump, and an integral condenser. The admission valve assembly includes a counterbalancing poppet valve and valve stem that creates counterbalanced unsupported areas that allow the poppet valve to operate at higher speeds. The AURE can be fueled by raw, unprocessed fuel, including biomass, to generate efficient energy in a smaller overall package. | 12-27-2012 |
