Which outcome occurs when direct fuel injectors in a diesel engine experience thermal cracking?

💡 Explanation

When injectors experience thermal cracking, incomplete combustion occurs because the fuel atomization is non-uniform, leading to regions of fuel-rich combustion that increase particulate matter emissions. Therefore, increased particulate matter results, rather than cylinder overheating, engine torque reduction, or fuel pump failure, which require different mechanisms.
