The EGR system allows a measured quantity of exhaust gas to be directed back to the
intake manifold. The exhaust gas is introduced to the incoming charge air in the intake
manifold, where it mixes with the air/fuel mixture and lowers the peak gas temperature,
reducing nitrogen oxide (NOx) exhaust emissions. The EGR valve is electrically operated
and is controlled through an input from the powertrain control module (PCM). The EGR
valve must not be disassembled or removed from the intake manifold.
The EGR system is fitted with an EGR cooler. The EGR cooler reduces the temperature of
the exhaust gasses being returned to the intake system. By reducing the EGR temperature,
the intake air charge density is not adversely affected, so maintaining the optimum fueling
characteristics.
