3) Control Logic

The EGR system controls the EGR amount based on the map values shown below:
※
Main map value: Intake air volume
※
Auxiliary map value:
- Compensation by the coolant temperature
- Compensation by the atmospheric pressure: Altitude compensation
- Compensation by the boost pressure deviation (the difference between the requested value and the
measured value of boost pressure)
- Compensation by the engine load: During sudden acceleration
- Compensation by the intake air temperature
The engine ECU calculates the EGR amount by adding main map value (intake air volume) and auxiliary
map value and directly drives the solenoid valve in the E-EGR to regulate the opening extent of the EGR
valve and sends the feedback to the potentiometer.

(1) Operating conditions

Intake air temperature: between -10 and 50℃
-
- Atmospheric pressure: 0.92 bar or more
Engine coolant temperature: between 0 and 100°C
-
- When there is no fault code related to EGR

(2) Shut off conditions

- Abrupt acceleration: with engine speed of 2600 rpm or more
- When the engine is idling for more than 1 minute
- Vehicle speed: 100 km/h or more
- Engine torque: 380 Nm or more
