Which constraint limits maximum efficiency in heat engines?

💡 Explanation

Carnot's Thermodynamic Efficiency limits ideal heat-engine performance, because it defines maximum efficiency based on temperatures, therefore no real engine exceeds this theoretical limit, rather than losses determine fuel consumption or mechanical conditions. Fuel and spark conditions depend on design not bounds.
