GF49.10-P-2010V Three-way Catalytic Converter, Component Description
Location
Near the engine in the front section of the exhaust system.
Task
Reduction of the following pollutants in the exhaust:
-
Carbon monoxide (CO)
-
Hydrocarbon (HC)
-
Nitrogen oxide (NOx).
In each catalytic converter, there are two ceramic monoliths with each approx. 600 cells. The exhaust gas flows through these passages. The ceramic
consists of high temperature-resistant magnesium aluminum silicate.
The monoliths are extremely sensitive to warping and are embedded in an elastic wire mesh of high-carbon steel wire and mounted inside a double-wall
housing of stainless steel.
Ceramic monoliths require a support layer of alumina (Al2O3) (the "washcoat"), which increases the effective surface of the catalytic converter by a
