What Four Processes Make Up The Ideal Air Standard Otto Cycle?

What Four Processes Make Up The Ideal Air Standard Otto Cycle? The four-stroke Otto cycle is made up of the following four internally reversible processes: 1–2, isentropic compression; 2–3, constant-volume heat addition; 3–4, isentropic expansion; and 4–1, constant-volume heat rejection. Which of the following lists the four steps of the Otto cycle? The four processes
