Which effect occurs when excessive fuel accumulates upstream of a closed intake valve in a gasoline engine?

💡 Explanation

When excessive fuel pools before a closed intake valve, hydraulic lock occurs because liquid fuel is incompressible, preventing the piston from fully compressing the mixture on the compression stroke. Therefore, hydraulic lock results, rather than misfire, pre-ignition or knocking which depend on different air/fuel ratios and ignition timings.
