This is a real 4-step heat engine that has expansion and compression processes in which the engine will do useful mechanical work by lifting a 100-gram mass (and the piston) from one height to another. The objective of this report is to identify and analyse the processes in each component, record data such as pressure and temperature at different locations as well as studying the refrigerant's phases (thermodynamic states) (Figure 2) to construct the refrigeration cycle on a real pressure enthalpy chart provided by SOLVAY. The equations used were under the assumption that the engines working substance is an ideal gas. The objective of the heat engine experiment is to comprehend the working principles of the heat engines, to plot the P-V diagram for the cycle experienced by the heat engine and to evaluate the work done by the heat engine. A device known as heat engine is used to convert thermal energy into other useful forms of energy.
