5.2 Feature of EGR system
The primary purpose of the EGR system is to reduce NOx in the exhaust gases.
NOx is generated through combustion at high temperature.
Combustion chamber temperature is lowered by the EGR system to reduce NOx.
Exhaust gases include components with high thermal capacity.
Returning
a part of the exhaust gases to the combustion chamber enables reducing the combustion chamber
temperature.
The amount of exhaust gas returned to the combustion chamber is controlled using the amount the EGR valve is
opened.
