Which risk increases when exhaust gas recirculation (EGR) significantly slows reaction rate?

💡 Explanation

Decreasing the reaction rate via EGR increases unburned fuel residence in cylinders creating hotspots; this is because slower combustion allows localized pre-ignition, therefore increasing engine knock events rather than decreasing them under normal conditions.
