Background
Exhaust Gas Recirculation (EGR) is a method of
reduce the high cylinder operating temperatures
reducing oxides of nitrogen (NOx) emissions by
where NOx is most likely to occur. Lower combustion
introducing non-combustible exhaust gases into the
chamber temperatures result in lower NOx emis-
combustion chamber. These gases absorb heat and
sions.
