Which consequence results when lubrication breakdown occurs continuously during Carnot cycle operation?

A)Piston/cylinder scoring accelerates drastically
B)Isothermal volume expansion fails fully
C)Adiabatic compression ends prematurely
D)Overall cycle efficiency remains unchanged

💡 Explanation

Lubrication breakdown causes increased friction which promotes adhesive wear; Piston/cylinder scoring accelerates drastically because friction coefficient rises, increasing material removal rate therefore greater wear occurs progressively rather than negligible or constant friction.
