Q: Why is 2.4-L referred to as the maximum volume instead of the displacement volume in Example 9-60?
note: maximum volume = V1. displacement volume=V1-V2

reference：
displacement volume
9-60
9-153
9-164
9-167

What is the definition of cutoff ratio?

Post #1 has too many links to read through and it is not clear why you have included them.

However, in the model answer for Example 9.60, the author uses ##V_1= 0.0024m^3 (=2.4L)## which, as you say, is incorrect. (I get ##V_1 = 2.514L##.) Presumably that's the problem about which you are asking.

So it looks like a simple mistake by the author.

$$r_c=\frac{V_3}{V_2}$$
