A diesel engine operating on the air-standard Diesel cycle has six cylinders of 100 mm bore and 120 mm stroke. The engine speed is 1800 rpm. At the beginning of compression, the pressure and temperature of air are 1.03 bar and 35 °C. If the clearance volume is 1/8th of the stroke volume, calculate (i) the pressure and temperature at the salient points of the cycle, (ii) the compression ratio, (iii) the efficiency of the cycle and (iv) the power output if the air is heated to 1500 °C Assume cp and cy of air to be 1.004 and 0.717 kJ/kg K respectively.
