일반물리학 1 — Entropy and the Second Law of Thermodynamics: Problem 37

37 The cycle in Fig. 20-28 represents the operation of a gasoline internal combustion engine. Volume \(V_3 = 4.00V_1\). Assume the gasoline–air intake mixture is an ideal gas with \(\gamma = 1.30\). What are the ratios (a) \(T_2/T_1\), (b) \(T_3/T_1\), (c) \(T_4/T_1\), (d) \(p_3/p_1\), and (e) \(p_4/p_1\)? (f) What is the engine efficiency?
