Which outcome occurs when an internal combustion engine's fuel injector nozzle gets partially clogged with carbon deposits?

💡 Explanation

When an injector nozzle clogs, fuel distribution becomes uneven due to inconsistent droplet size because of altered spray pattern from injector. Therefore, increased engine knocking results from pre-ignition rather than reduced emission, oil viscosity, or turbocharger issue, who require larger scale systemic faults.
