Which outcome occurs when a diesel engine's fuel injectors malfunction, injecting excess fuel during each cycle?

💡 Explanation

Incomplete combustion leads to soot formation because the high fuel-air ratio during each engine cycle hinders complete oxidation; therefore soot accumulates inside the cylinders, rather than efficient combustion and lower emission, resulting in lower cylinder wear.
