EXHAUST SYSTEM [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)]

id0115m1125800

Outline

• A high compression ratio has been realized by adopting 4-2-1 exhaust pipes and reducing residual gas in the cylinders.

• The loop structure of the exhaust pipes for the 4-2-1 system takes up less space.
