Hyundai i-30: Engine Control System / Electric Exhaust Gas Recirculation (EEGR) Control Valve
Description and operation
The Electric EGR Control Valve is installed in between the EGR cooler and the
exhaust line and is a solenoid valve. This valve controls EGR (Exhaust Gas Recirculation)
amount by the ECM's duty control signal depending on engine load and the need
of intake air.
The Exhaust Gas Recirculation (EGR) system is used to add the exhaust gas to
intake air in order to reduce an excess of air and the temperature in the combustion
chamber.
