EMISSION SYSTEM [SKYACTIV-X 2.0]

id0116hf110100


Outline

•  A single-nano catalyst has been adopted for the three-way catalyst to improve emission gas purification efficiency.
•  The emission system purifies contaminants (CO, HC, NOx) in the exhaust gas, blow-by gas, and evaporative gas exhausted from the vehicle.
•  Gasoline particulate elimination equipment (gasoline particulate filter) has been adopted which eliminates PM from the exhaust gas.
