EMISSION REDUCTION SYSTEMS


These decrease CO, HC and NOx in the exhaust gases and consist of air-fuel ratio feedback control and catalytic converter.

1. AIR-FUEL RATIO FEEDBACK CONTROL


Refer to GROUP 13E - Fuel Injection Control .

2. CATALYTIC CONVERTER



The exhaust manifold and the centre exhaust pipe include a catalytic converter.
Based on appropriate air-fuel ratio feedback from linear air-fuel ratio sensor and oxygen sensor (rear), CO and HC are oxidized and NOx is reduced. Catalytic converter is a monolith with beehive design with catalysts on the unit surface. It is protected by a thermally insulating mat and enclosed in a shell.
