Assembly EGR Cooler Module with EGR
Valve and By Pass Valve
Assembly EGR cooler module consists of the
EGR cooler
EGR valve
Bypass valve
The EGR cooler assembly is provided with inbuilt
electronic EGR and a by-pass valve.
The EGR Cooler is a heat exchanger that is used
to cool the exhaust gases before they are
recirculated to the intake manifold. The hot
exhaust gases are routed into the EGR cooler
from the exhaust pipes through the EGR valve. In
the EGR cooler, the exhaust gases are made to
pass through metal tubes that are surrounded by
engine coolant. The cooled exhaust gas is more
effective to help to reduce the pollutants.
The EGR valve is electrically operated by the
EMS. There is an EGR Cooler bypass valve,
which is controlled through the EMS using an
electro-pneumatic valve.
