railway RRB JE (CBT I + CBT II) Mock Test 2024 Internal Combustion Engine IC Engine Cycles Otto Cycle
The pressure and temperature of air at the beginning of compression in an Otto cycle is 100 kPa and 300 K, respectively. The heat added per kg of air is 1436 kJ. The compression ratio is 8. What will be the maximum temperature of the cycle? [Ratio of specific heat = 1.4; 80.4 = 2.3; Cv = 0.718 KJ/kg-K.]
