EGR System Monitor


Emissions of NOx increase proportionally with the temperature in the combustion chamber. The Exhaust Gas Recirculation (EGR) system is designed to circulate non-combustible exhaust gases into the manifold to dilute the A/F mixture. In this manner, the EGR system lowers the combustion temperature and reduces NOx emissions and pre-detonation (knocking).
