Which mechanism limits usable energy output in a continuously running combustion engine exhausting to atmosphere?

💡 Explanation

When combustion exhaust is released, increasing entropy occurs because heat disperses into the environment, increasing disorder in the system according to the Second Law, ultimately causing less heat available for doing work. Therefore, increasing entropy, heat dissipation results, rather than valve backflow, injector problems, or piston friction which involve purely mechanical losses.
