Which outcome results when differential fuel vaporization occurs in multi-cylinder engines?

💡 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.
