Stirling Engine Diagram. Many stirling engines have a gas pressure inside them that is nearly equal to the outside atmospheric pressure. The processes are described with the pv diagram as shown in fig.
Let us now consider the four stages of the stirling cycle. When you heat the outside of the engine the gas expands and pushes the piston out. High speed engines of any type will have a pv diagram that looks round on the edges like this one.
Let us now consider the four stages of the stirling cycle.
Many stirling engines have a gas pressure inside them that is nearly equal to the outside atmospheric pressure. Higher and lower temperatures in the stirling cycle diagram. This video describes and demonstrates the real time measurement of a stirling engines pressure versus volume diagram. In this illustration the lower left cylinder is heated by burning fuel.
