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

Cautions to protect the catalyst filter

▶

Use the designated fuel only.                                

Observe the recommended service intervals of engine oil.

Check the engine oil level frequently and add if necessary.               

Do not idle the vehicle unnecessarily.

Do not turn off the engine while the vehicle is running.                   

Do not shift the gear selector lever to neutral when going downhill.

Do not use improper engine oil or fuel additives.

Do not drive for a long time when the warning lamp is illuminated.

Make sure no flammable material, such as dry grass or tissue paper, contacts with the catalyst filter 

while the vehicle is parked.

For the vehicles used in urban traffic, driving on the expressways for more than 1 hour at least once 

per week is needed so that the PM inside CDPF isn't collected to one side only.
