Some Developments in Small Reciprocating Rankine-Cycle Engines Using Organic Working Fluids 700162
Thermo Electron's development program on Rankine-cycle engines is reviewed. Intake valve losses are shown to be an important aspect of engine efficiency, particularly with organic working fluids. Experimental data on engine indicated efficiencies are presented, and show values to 80%. These results were demonstrated in an engine with less than 1.0 CID.
