EMISSION REDUCTION SYSTEMS




1. AIR-FUEL RATIO FEEDBACK CONTROL


Refer to GROUP 13D <4B12> - Fuel Injection Control .
Refer to GROUP 13C <6B31> - Fuel Injection Control .

2. CATALYTIC CONVERTER




Catalytic converter is installed in the center of exhaust pipe below the floor and in the exhaust manifold junction of each bank <6B31> Based on appropriate air-fuel ratio feedback from oxygen sensor, 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.
