Component Location: Overview

WARNING: This page is about a different variant/trim than selected.

The engine emission control system reduces the level of hydrocarbon emissions released to atmosphere from the engine.

The engine emission control system consists of a PCV (Positive Crankcase Ventilation) system with part and full load breathers.

Piston blow-by gases and metered fresh air are drawn through the breathers into the engine air intake and added to the air charge. The resultant depression in the engine sump, front covers and cylinder head covers reduces the load on the joint seals in those areas.
