4. A CI engine operating on the air standard diesel cycle, has cylinder conditions at the start of
compression of 65 o C and 130 kPaa. C 12.3 H 22.2 fuel is used (Q HV = 42, 500 kJ/kg) at an equivalence ratio
of 0.81 with a combustion efficiency of 98 %. The engine is 2.4L, 4 cylinder and is operating at 2000
rpm. Mechanical efficiency is 95%, and compression ratio of 19. Assuming that Indicated engine
efficiency is 100 % and no exhaust residual.

Calculate: a) P,V and T at cycle state points, b) cut off ratio, c) bore and stroke for a square engine, d)
indicated work net, e) brake thermal efficiency, f) Indicated power produced by the engine, g) torque, h)
volumetric efficiency, i) Brake mean effective pressure, j) Indicated specific fuel consumption [gm/kW-
