← TechnologyWhich outcome results when differential fuel vaporization occurs in multi-cylinder engines?
A)Lean Knock in specific cylinders✓
B)Uniform Exhaust Gas Temperatures
C)Optimized Catalytic Converter Efficiency
D)Balanced Cylinder Power Output
💡 Explanation
Differential fuel vaporization leads to some cylinders receiving less fuel because fuel fractions with higher boiling points remain unvaporized. This uneven distribution causes lean mixtures triggering detonation or knock rather than power balance; therefore, lean knock is the immediate consequence.
