Question: An SI engine, modeled as an ideal Otto cycle, runs at a compression ratio of 9.6:1 with a maximum cylinder volume (V 1 ) of

An SI engine, modeled as an ideal Otto cycle, runs at a compression ratio of 9.6:1 with a maximum cylinder volume (V₁) of 2 L and a corresponding displacement of 1.8 L. Combustion leads to a maximum temperature of T₃ = 1800K. Using the air standard value of γ = 1.3, find the engine efficiency and the work per cycle. Compute the engine’s power at 5000 rpm. Assume that the in take temperature and pressure are 300K and 100 kPa. you will need the value of C_V from Problem 11.2.
