Gasoline engines operate approximately on the Otto cycle, consisting of two adiabatic

Chapter 19, Problem 53

(choose chapter or problem)

Gasoline engines operate approximately on the Otto cycle, consisting of two adiabatic and two constant-volume segments. Figure 19.24 shows the Otto cycle for a particular engine. (a) If the gas in the engine has specific heat ratio find the engines efficiency, assuming all processes are reversible. (b) Find the maximum temperature in terms of the minimum temperature (c) How does the efficiency compare with that of a Carnot engine operating between the same temperature extremes?
