5- The mechanical and indicated thermal efficiencies of 4-stroke four cylinder over square
engine are (83% & 33%) respectively. The fuel calorific value of (42000) kJ/kg is consumed
at a rate of (20 kg/hr.) when running at a fixed speed. The brake mean effective pressure
developed is (6.4) bar. The combustion process was completed when the crank angle is 20°
ATDC with piston speed ( 8.5 ) m/s and the volume is 80cm', the ratio of connecting road
length to the crank shaft off set is 3.75. Calculate the connecting road length and the camshaft
speed of the engine.
[ Take Cr = 11]
