EGR System
Exhaust Gas Recirculation System (EGR)
The EGR system is designed to reintroduce exhaust gas into the combustion chambers, thereby lowering combustion temperatatures and reducing the formation of Oxides of Nitrogen.
The amount of exhaust gas that is reintroduced into the combustion cycle is determined by several factors, such as :
engine speed
engine vacuum
exhaust system back-pressure
coolant temperature
throttle position
