Problem 1 (65 pts): The cylinder of a Diesel engine is initially filled with air at 100 kPa and 298 K (piston is at BDC). The air is then compressed isentropically with a compression ratio of 20. Fuel, n-dodecane, is then introduced and combusted with the air, which produces work output (i.e. pushes the piston back to BDC). At the end of the power stroke, the temperature of the combustion products is 1020 K. The amount of heat lost to...
