A spark-ignition engine operates on an ideal Otto cycle with a compression ratio of 8. At the beginning of the compression process, air is at 100 kPa and 17°C. Calculate the thermal efficiency of the cycle.

Keep in mind that these are just sample problems and solutions. For a complete and accurate solution manual, I recommend purchasing the official solution manual or accessing instructor resources. solucionario termodinamica cengel julio 9ed

Using the Otto cycle equations, we can calculate the thermal efficiency: A spark-ignition engine operates on an ideal Otto

η = 1 - (1/r^(γ-1)) = 1 - (1/8^(1.4-1)) ≈ 56.5% solucionario termodinamica cengel julio 9ed
