← TechnologyWhich outcome occurs when biodiesel fuel degrades in a common rail diesel injection system?
A)Increased fuel injector nozzle clogging✓
B)Reduced engine block heat conduction
C)Decreased turbocharger turbine efficiency
D)Elevated fuel pump cavitation threshold
💡 Explanation
When biodiesel degrades, oxidation and polymerization form gums and sediments because unsaturated fatty acids react, leading to injector nozzle clogging. Therefore, increased nozzle clogging results, rather than altered block conduction, turbocharger performance, or pump cavitation which involve different mechanical aspects of system.
