7- 4 EMISSION CONTROL SYSTEMS
H020C01S-GAT
EGR SYSTEM ; For a diesel engine
This system helps control oxides of nitrogen by recirculating a part of theexhaust gas into the engine.
Diesel Particulate Filter (If Installed) The Diesel Particulate Filter (DPF) system removes the soot emitted from the vehicle. Unlike a disposable air filter, the DPF system automatically burns (oxidizes) and removes the accumulated sootaccording to the driving condition. In other words, the active burning by engine control system and high ex-haust gas temperature caused by nor- mal/high driving condition burns and removes the accumulated soot.However, if the vehicle continues to bedriven at low speed for long time, theaccumulated soot may not be auto- matically removed because of low exhaust gas temperature. In this par-ticular case, the amount of soot is out of detection limit, the soot oxidation process by engine control system maynot happen and the malfunction indica- tor light may blink. When the malfunction indicator light blinks, it may stop blinking by driving the vehicle at more than 60km/h (37 mph) or at more than second gear with1500 ~ 2000 engine rpm for a certain time (for about 25 minutes). If the malfunction indicator light con-
tinues to be blinked in spite of the procedure, please visit an authorizedHYUNDAI dealer and then check the DPF system.
If you continue to drive with the mal-
function indicator light blinking for a long time, the DPF system can bedamaged and fuel consumption can be worsen.
