The cycle for a heat engine consists of Compression from points 1 to 2. No heat flow but work done on the gas is 460 kJ. Constant volume heating from points 2 to 3. Heat flow into the gas is 128 kJ. Constant pressure expansion from points 3 to 4. Work done by the gas is 37 kJ. Heat flow into the gas is 128 kJ. Expansion from points 4 to 5. No heat flow but work done is 598 kJ. Constant volume cooling from points 5 to 1. Heat flow out of the gas is 81 kJ. The thermal efficiency of this cycle is
