A small single-cylinder, two-stroke cycle SI engine operates at 8000 RPM with a volumetric efficiency of v = 0.85. The engine is square (bore = stroke) and has a displacement of 6.28 cm³. The fuel-air ratio FA = 0.067. Calculate: (1) Average piston speed. [m/sec] (2) Flow rate of air into engine. [kg/see] (3) Flow rate of fuel into engine. [kg/see] (4) Fuel input for one cycle. [kg/cycle] Ans: (1) 5.33 m/s (2) 0.00084 kg/sec (3) 5.63*10-5 kg/sec (4) 4.22*10-7 kg/cycle
