The Otto Cycle: Thermodynamics for Mechanical Engineers

The Otto cycle is a reasonable way to model spark ignition engines analytically. The key characteristic of an Otto cycle is that we assume that heat is added at constant volume.

In this example, you’ll learn the process for solving Otto cycle analyses by applying the ideal gas law and identifying the isentropic processes to help fix states. We’ll also work through an example numerically to give you an idea of how to do these problems on your own.

Great content! excellent refresher. Whats confused me is how to approach a 2nd law analsysis on an internal combustion engine. Entropy is an odd beast to get the mind around
