Which risk increases when biofuel impurities disrupt combustion cycles?

A)Injector nozzle clogging develops rapidly

B)Increased exhaust valve thermal fatigue✓

C)Fuel pump cavitation becomes substantial

D)Reduced catalyst bed efficiency occurs

💡 Explanation

Incomplete combustion deposits carbon on exhaust valves; cyclic thermal stress rises because energy isn't fully captured due to uneven combustion. Therefore, fatigue increases, rather than simple clogging or cavitation which can happen, independent of combustion cycle consistency issues.
