Which outcome occurs when fuel injector nozzle erosion compromises atomisation in a diesel engine?

💡 Explanation

When nozzle erosion degrades atomisation, larger fuel droplets form because the surface area decreases, leading to incomplete combustion and increased particulate matter emissions. Therefore elevated PM emissions result, rather than oil viscosity reduction, increased EGT, or compressor speed reduction which need different engine malfunctions.
