Piston descends, inlet valve opens. Air drawn in at constant pressure (Line 1–2).
Piston ascends, both valves closed. Pressure increases and volume decreases to point 3, combustion at constant volume results in sharp pressure rise to point 4.
Increased pressure at constant volume forces piston down, resulting in increases in volume and drop in pressure (Line 4–5).
Exhaust valve opens, releasing combustion charge with rapid drop in pressure at constant volume (Line 5–2). Piston rises and forces remaining gases out of exhaust at constant pressure (Line 2–1). Cycle begins again at point 1.
