Exhaust filter Three way catalytic converter for Toyota Land cruiser prado 3400 middle catalyst

The exhaust gases from the engine pass through the exhaust manifold and into the TWC. The TWC is composed of a ceramic honeycomb structure coated with a thin layer of precious metals such as platinum, palladium, and rhodium.

As the exhaust gases pass through the honeycomb structure, the precious metals catalyze a series of chemical reactions that break down the pollutants. CO is converted to CO2, HC is oxidized to CO2 and H2O, and NOx is reduced to N2 and H2O.

The Toyota Land Cruiser Prado 3400 middle catalyst is an essential component of the vehicle's emission control system, helping to ensure that it meets the required emissions standards. Regular maintenance and inspection of the TWC can help to prolong its lifespan and ensure that it continues to operate effectively
