Problem 2: A large, straight six, compression-ignition truck operates on an air-standard Diesel cycle using heavy diesel fuel (Qur=41,400 kJ/kg) with 98% combustion efficiency. The engine has a compression ratio of 16.5:1. Temperature and pressure in the cylinders at the start of the compression stroke are 55°C and 102 kPa, and the maximum cycle temperature is 2410 °C. Calculate: a) Temperature, pressure and specific volume at each state of the cycle. Tabulate your results. b) The air-to-fuel ratio of the cylinder gas mixture. c) The gas temperature at EVO. d) The indicated thermal efficiency.
