← TechnologyWhich outcome occurs when backflow contaminates a diesel engine's injectors?
A)Increased combustion chamber knocking intensity✓
B)Decreased exhaust catalyst conversion efficiency
C)Augmented particulate filter regeneration frequency
D)Elevated intake manifold oxygen concentration
💡 Explanation
Contamination causes irregular fuel dispersion creating localized lean mixtures; because auto-ignition temperatures are quickly attained, leading to premature combustion knocking, caused by fuel "puddling," rather than homogenous mixture ignition. Therefore, knocking increases, rather than improved catalyst efficiency under regular combustion phases.
