The compression stroke of an Otto cycle decreases the cylinder volume from V1 = 0.04 m³ to V2=0.01 m³. If the initial pressure and temperature are P₁ = 100 kPa and T₁ = 75 °C, respectively, determine (A) the mass of air in the engine, m, and (B) the maximum cycle pressure, P2. Assume the fluid is air with an effective specific heat ratio of k = 1.33.

The displacement volume of an internal combustion engine is 2.16 liters. The processes within each cylinder of the engine are modeled as an air-standard Diesel cycle with a cutoff ratio of 2.5. The state of the air at the beginning of compression is fixed by p1 = 1.6 bar, T1 = 325 Kand V1 = 2.36 liters. If the cycle is executed 2100 times per min, determine: a) the compression ratio, b) the net work per cycle, in kJ, c) the maximum temperature, in K, d) the power developed by the engine, in kW, e) and the thermal efficiency.
