5 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- 6×10 5 N/m 2 Area,A- π×d 2 = π×.04 2 = 1.25×10 -3 4 4 IMEP= IP×60 (L×A×N×K) 6×10 5 = IP × 60.04×1.25×10 -3 ×308×3 ie, IP=462 W MAR BASELIOS.C.E.T 5

6 Overall efficiency = IP × 100% i/p =462 × 100% 1983.47 = 23.29% MAR BASELIOS.C.E.T 6

7  Tidal Waves  Wind Mills

8  Cost of fossil fuels  Employment by compressed air production  Low cost of engine  Low running cost

9  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
