Which outcome occurs when diesel particulate filters excessively restrict exhaust flow?

💡 Explanation

Excessive backpressure from the DPF forces the engine to work harder to expel exhaust, meaning less oxygen is available for each fuel injection cycle; therefore, fuel pools because of incomplete oxidation, producing soot rather than complete combustion.
