Monitor "AIR MASS PER CYLINDER" and "EGR ACTUATOR" parameter on the GDS.
Reference value : At idle condition.
When EEGR actuator does not operate (Approx. 5% duty) at idle : 400mg/st ~ 500mg/st
Fig.1) Intake amount during no EEGR actuator operation under warm -up at idle condition (5.1%) : 400mg/st ~ 500mg/st
☞ When EEGR actuator does not operate at idle, Sudden acceleration then, deceleration make EEGR actuator operates and operating duty for EEGR actuator decreases as time goes by. This control lasts for approx. 60sec. after that, EEGR actuator is OFF(95%)
Fig.2) Intake amount during no EEGR actuator operation at 4000 rpm (4.7%)
Reference values : EGR duty and sensor data for MAFS under intake temperature 48 ℃
EGR duty(%) | 5~40 | 42 | 44 | 45 | 47 | |
Intake air | (mg/st) | 440 | 355 | 290 | 260 | 236 |
(kg/h) | 57 | 52 | 41 | 38 | 31 | |
