Which outcome occurs when a diesel engine's fuel injector nozzle erodes, increasing its orifice size?

💡 Explanation

When nozzle erodes, the fuel injection timing advances and fuel quantity per cycle increases as injection pressure drops, leading to incomplete combustion at peak compression. Therefore, elevated cylinder temperatures and knocking result, rather than other outcomes which require distinct mechanical issues or fuel calibrations.
