Carnot Engine . Cycles. Objective. The purpose of this lesson is to examine the . Carnot engine cycle.. The Carnot Engine. The heat engine that operates the most efficiently between a high-temperature reservoir and a low temperature reservoir is the Carnot engine.. A generalized heat engine.

Consider a gas in a cylinder with a movable piston. . If the piston is pushed inward by an external force, work is done on the gas, adding energy to the system.. The force exerted on the piston by the gas equals the pressure of the gas times the area of the piston: . J. G. Weisend II. Deputy Head of Accelerator Projects.
