← ScienceWhich outcome occurs when maximizing thermal efficiency in engines?
A)Heat engine nears Carnot limit✓
B)Incomplete fuel-air mixture combustion
C)Piston rings experience thermal expansion
D)Exhaust pollutants decrease significantly
💡 Explanation
Thermal efficiency maximization leads to performance near the Carnot limit, because the engine attempts to minimize entropy production via irreversible processes; therefore, Carnot limitation occurs rather than increasing pollutants or directly affecting engine component wear.
