Energy conversion diagram of an internal combustion automobile.

Diagram of a car showing the distribution of 100 units of gasoline energy, with arrows indicating energy losses: 33 units through exhaust, 29 through cylinder cooling, 6 due to air pumping, 4 from other friction, and 3 from piston ring friction, leaving 25 units as usable horsepower.

This diagram illustrates the distribution of energy in a car’s internal combustion engine, showing how 100 units of gasoline energy are used and lost across various components. The image highlights energy losses due to exhaust, friction, air pumping, and cooling, leaving a smaller portion as usable horsepower. Ideal for physics or automotive engineering textbooks, this diagram helps students understand energy efficiency and heat loss in mechanical systems.
