Extracted text: In an engine working on the Diesel eycle the ratios of the weights of air and fuel supplied is 50: 1. The temperature of air at the beginning of the compression is 60 °C and the compression ratio used is 14: 1. What is the ideal efficiency of the engine, Calorifie value of fuel used is 42000 k.J/kg. Assume C, - 1.004 kJ/kg K and C, = 0.717 kJ/kg K for air.
