THREE CYLINDER ROTARY PNEUMATIC ENGINE • WHAT IS PNEUMATIC ENGINE ? • IDEA BEHIND THE PROJECT • HOW IT WORKS ? • WHY THREE CYLINDER ENGINE ?
ANALYSIS • Engine power • Bore diameter ,d– 40 mm = .04 m • Stroke length ,L – 40 mm = .04 m • Speed ,N – 308 rpm • Number of cylinder ,K- 3 • Indicated Mean Effective Pressure ,IMEP- 6×105 N/m2 • Area ,A- π×d2= π×.042 = 1.25×10-3 • 4 4 • IMEP= IP×60 (L×A×N×K) • 6×105 = IP × 60 .04×1.25×10-3×308×3 • ie, IP=462 W MAR BASELIOS.C.E.T
ANALYSIS • Overall efficiency = IP × 100% i/p • =462 × 100% 1983.47 • = 23.29% MAR BASELIOS.C.E.T
GENERATION OF COMPRESED AIR • Tidal Waves • Wind Mills
MANAGEMENT CRITERIA • Cost of fossil fuels • Employment by compressed air production • Low cost of engine • Low running cost
FUTURE DEVELOPMENT • FOR THIS ENGINE TO INCREASE EFFICIENCY 1) CYLINDER BORING 2) NYLON CAP ABOVE PISTON 3) COPPER TUBES FOR AIR FLOW 4) AIR LEAK FREE JOINTS • DUO ENGINE
