SUNDSTRAND'S ORC ENGINE GOES FOR A BUS RIDE

AN ORGANIC RANKINE CYCLE ENGINE DEVELOPED BY SUNDSTRAND AVIATION DEMONSTRATED THE FEASIBILITY OF POWERING CITY BUSES BY AN EXTERNAL COMBUSTION ENGINE. FUEL IS BURNED TO GENERATE SUFFICIENT HEAT TO VAPORIZE THE FLUID, WHICH THEN IS DIRECTED TO THE TURBINE WHEEL TO PRODUCE ROTATIONAL FORCE FOR THE OUTPUT SHAFT. THE EXHAUSTED VAPOR IS PASSED THROUGH A REGENERATOR TO TRANSFER ANY LEFTOVER HEAT TO THE RETURNING FLUID. THE USE OF AN ORGANIC FLUID IN PLACE OF WATER ALLOWS THE SYSTEM TO OPERATE EFFICIENTLY WITH REASONABLE-SIZED TURBOMACHINERY COMPONENTS. THE BUS PERFORMS COMPARABLY TO PRESENT CITY BUSES, AND ITS EMISSIONS ARE WELL BELOW THE 1967 STANDARDS FOR NOSUBX, HC AND CO DUE TO THE EXTERNAL COMBUSTION. THE ENGINE MEETS NOISE LIMITS, AND CAN BURN ANY OF SEVERAL DIFFERENT KINDS OF FUEL. IT PROVES THAT SUBSTANTIAL REDUCTIONS OF EMISSIONS, NOISE AND VIBRATION ARE POSSIBLE USING AVAILABLE MATERIALS AND PROVEN TECHNOLOGY.
