A four-cylinder, four-liter CI engine operates on air-standard Dual cycle at a compression ratio of 15:1. At the start of the compression stroke, conditions in the cylinders are 50C and 95 KPa. If the heat added at constant volume is 1.378 kJ, the heat capacity ratio is 1.35, the heat capacity at constant volume is 0.821 kJ/kg K, and the air gas constant is 287 J/kg.K, calculate the temperature at state x (T) [6 marks]
