The operating principles of a four‐stroke engine are used to illustrate the basic principles that govern the engine limitations and engine efficiency. The purpose is to give an in‐depth understanding of the engine as a process that can be used as a foundation on which modeling, control, and diagnostics problems can be built. For modeling and analysis, the thermodynamical cycle is divided into several separate processes that are modeled individually. The assumptions made in the modeling of the different processes are summarized in this chapter. The chapter also summarizes and describes the most important results from the ideal gas cycles. It demonstrates the development of detailed models, capable of describing the measured pressure traces more accurately. These models incorporate effects such as finite burning time, as well as heat and mass transfers, giving models that cannot be solved analytically but instead can be simulated using computers.
