Consider an air-standard Otto cycle. At the beginning of the compression process, the pressure and temperature are 1 bars and 300 K. The displacement volume is 2 liters, compression ratio is 10 and the pressure at the end of the combustion is 4 times the pressure at the end of the compression.Use cold-air standard calculations and determine:1-the pressure, temperature and volume at each state and fill in the below table. 2-the net work per cycle. 3- the thermal efficiency of the cycle.
The cycle involved in the operation of an internal combustion engine is called the Otto cycle. Air can be considered to be the working substance and can be assumed to be a perfect gas. The cycle consists of the following steps: I) Reversible adiabatic compression from A to B. 2) Reversible constant-volume pressure increase from B to C due to the combustion of a small amount of fuel. 3) Reversible adiabatic expansion from C to D. 4) Reversible and constant-volume pressure decrease back to state A. Determine the change in entropy (of the system and of the surroundings) for each step of the cycle and determine an expression for the efficiency of the cycle, assuming that the heat is supplied in Step 2. Evaluate the efficiency for a compression ratio 10:1. Assume that in state A, V=4.00 dm', p= 1.00 atm, T= 300 K, that VA = 10 Vb, pc/pb = 5, and that Cp.m = (7/2)R Note that R = 8.314 J K-1 mol-1 and dm = 10-1 m.
