The engine in the figure operates at 50 rpm. ATM conditions are 101 kPa and 17 C. a) Considering that the engine has 4 cylinders and 4 stroke, find the amount of air it absorbs per unit time. b) If Y/H= 0.065, find the amount of fuel used per unit time. c) If Hu =43000 kJ/kg, relative =0.85, ym=0.73, Vc=30 cc, find the Pe and Pi powers of the engine. d) Find the average effective pressure (pme) and effective specific fuel consumption of the engine.
