Which outcome occurs when elevated exhaust gas recirculation (EGR) lowers combustion temperatures excessively in diesel engines using dual fuel injection?

💡 Explanation

Higher EGR flow lowers combustion temperatures; incomplete oxidation occurs due to insufficient heat. The mechanism is flame quenching, because partial oxidation produces unburned hydrocarbons and carbon monoxide, therefore increasing UHC emissions rather than completing combustion.
