The document discusses the Otto cycle, which models the thermodynamic cycle of spark ignition engines. It describes the Otto cycle process as involving reversible adiabatic compression and expansion as well as constant volume heat addition and rejection. Diagrams of the P-V and T-S representations of the Otto cycle are presented. The document also provides numerical examples and is authored by Dr. Dinesh Kumar on applied thermodynamics and the Otto cycle used in internal combustion engines.
