The piston of an oil engine, of area 0.0045 m², moves downwards 75 mm, draw-
ing in 0.00028 m' of fresh air from the atmosphere. The pressure in the cylinder
is uniform during the process at 80 kPa, while the atmospheric pressure is
101.325 kPa, the difference being due to the flow resistance in the induction
pipe and the inlet valve. Estimate the displacement work done by the air finally
in the cylinder.
