Otto, Diesel, and Dual Cycles

Consider an air-standard Otto cycle. Operating data at principal states in the cycle are given in the table below. The states are numbered as in Fig. 9.3. The mass of air is 0.002 kg. Determine Consider a cold air-standard Otto cycle. Operating data at principal states in the cycle are given in the table below. The states are numbered as in Fig. 9.3. The heat rejection from the cycle is 86 Btu per lb of air. Assuming c_v = 0.172 Btu/lb . °R, determine

(a) the compression ratio.

(b) the net work per unit mass of air, in Btu/lb.

(c) the thermal efficiency.

(d) the mean effective pressure, in lbf/in.²
