WebFeb 20, 2024 · Any heat engine employing the Carnot cycle is called a Carnot engine. Figure 15.4. 1: This novelty toy, known as the drinking bird, is an example of Carnot’s engine. It contains methylene chloride (mixed with a dye) in the abdomen, which boils at a very low temperature—about 100 o F. To operate, one gets the bird’s head wet. WebA heat engine can only convert part of the energy it received from the source to work. A certain amount of heat is dissipated to the sink as waste heat.

A Carnot heat engine is a heat 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.
