System
 Objective/Function
 Composition
Exhaust gas recirculation (EGR) system
 NOx decrease.
Reduce NOx generation by controlling exhaust gas recirculation volume according to engine warm-up condition and driving conditions.
  • EGR valve (DC motor)
  • EGR valve position sensor
  • EGR cooler
  • EGR cooler solenoid valve
Diesel particulate filter (DPF) system
 Particulate matter (PM) is removed.
PM accumulated in the diesel particulate filter is removed.
  • DPF assembly
  • Exhaust differential pressure sensor
  • Exhaust gas temperature sensor
Fuel additive system
 Mixing fuel additive with fuel at constant rate allows PM at DPF regeneration to be burned at lower exhaust gas temperature.
  • Fuel additive tank (fuel additive pump)
  • Fuel additive-ECU
  • Fuel tank cap presence sensor
Emission reduction system
 Fuel injection control
 Particulate Matter (PM) decrease.
 Common rail
Catalytic converter
 CO and HC decrease.
Reduces the CO and HC in the exhaust gas, by promoting their oxidation reaction.
 Monolith catalyst
