The Exhaust Gas Recirculation (EGR) system helps reduce NOx emissions by recirculating a portion of an engine's exhaust gas back to the engine cylinders. Insufficient EGR flow can lead to higher combustion temperatures, which can cause the engine to overheat, increase the risk of detonation (premature combustion), and emit excessive amounts of NOx. Therefore, all the given conditions may result from too little EGR flow.
