HEAT ENGINE CYCLE DIAGRAM
Heat Engine Cycle
Engine Cycles For a constant mass of gas, the operation of a heat engine is a repeating cycle and its PV diagram will be a closed figure. The idea of an engine cycle is illustrated below for one of the simplest kinds of cycles. If the cycle is operated clockwise on the diagram, the engine uses heat

OverviewCarnot's diagramModern diagramCarnot cycleCarnot's theoremEfficiency of real heat enginesA Carnot heat engine is a theoretical engine that operates on the Carnot cycle. The basic model for this engine was developed by Nicolas Léonard Sadi Carnot in 1824. The Carnot engine model was graphically expanded by Benoît Paul Émile Clapeyron in 1834 and mathematically explored by Rudolf Clausius in 1857, work that led to the fundamental thermodynamic concept of entropy. Every thermodynamic system exists in a particular state. A thermodynamic cycle occurs when a system is takSee more on enpedia · Text under CC-BY-SA license
PV Diagrams Pressure-Volume (PV) diagrams are a primary visualization tool for the study of heat enginese the engines usually involve a gas as a working substance, the ideal gas law relates the PV diagram to the temperature so that the three essential state variables for the gas can be tracked through the engine cycle. Since work is done only when the volume of the gas changes, the

Heat Cycle Analysis. The characteristics of the heat cycle associated with a heat engine are normally described by means of two state change diagrams, the PV diagram showing the pressure - volume relationship, and the TS diagram showing the temperature - entropy relationship.

For any kind of heat engine or refrigerator (reverse heat engine), the processes involved form a cycle on the P-V graph. The work is the area of the enclosed region on the graph. The diagram for a refrigerator is a little more complicated than this because of the two phase changes involved, but this is basically what it looks like:
Heat Engines: the Carnot Cycle
This simplest heat engine is called the Carnot engine, for which one complete heating/cooling, expanding/contracting cycle back to the original gas volume and temperature is a Carnot cycle, named after Sadi Carnot who in 1820 derived the correct formula for the maximum possible efficiency of such a heat engine in terms of the maximum and minimum gas temperatures during the cycle.

Carnot Cycle. Carnot Heat engine (based on Carnot Cycle) was a concept developed by Nicolas Leonard Sadi Carnot (1796-1832, a French Military Engineer and Physicist) so that one can visualize a reversible heat engine in practice. Carnot engine is a reversible heat engine which works on Carnot cycle.

The Carnot Cycle has performed as an engine, converting the heat transferred to the gas during the processes into useful work. A similar Brayton Cycle explains how a gas turbine engine works, and an Otto Cycle explains how an internal combustion engine works.

The Carnot heat engine is a reversible heat engine working between cycles of operations. So, in the Carnot heat engine, the ideal gas, which is used as a working substance comes back to its initial state at the end of each cycle. What is the Carnot cycle? The Carnot heat engine works on the four reversible processes. Isothermal gas expansion
