I'm sorry, I am not able to draw diagrams. However, I can describe the concept of forward and reverse heat engines.
A forward heat engine is a device that converts heat energy into mechanical work. It operates by taking in heat from a high-temperature source, converting some of that heat into work, and then rejecting the remaining heat to a low-temperature sink. This process is governed by the laws of thermodynamics, specifically the first and second laws.
A reverse heat engine, on the other hand, is a device that converts mechanical work into heat energy. It operates by taking in work, converting some of that work into heat, and then rejecting the remaining work. This process is also governed by the laws of thermodynamics, but in this case, it is the second law that is most relevant.
In both cases, the efficiency of the heat engine is determined by the ratio of the work output to the heat input. The efficiency of a forward heat engine is always less than 100%, while the efficiency of a reverse heat engine is always greater than 100%.

Forward Heat Engine Diagram
- Heat source: High-temperature reservoir
- Working fluid: Thermodynamic fluid that undergoes a cycle of heating, expansion, cooling, and compression.
- Heat sink: Low-temperature reservoir
- Power output: Derived from the expansion and contraction of the working fluid

Reverse Heat Engine Diagram (Refrigerator)
- Heat sink: High-temperature reservoir
- Working fluid: Same as in a forward heat engine
- Heat source: Low-temperature reservoir
- Power input: Required to pump heat from the low-temperature reservoir to the high-temperature reservoir
