Catalytic Converter: Description and Operation
Catalytic Converter
Catalytic Converter
The catalytic converter serves two purposes: it permits a faster chemical reaction to take place and although it enters into the chemical reaction, it
remains the same, ready to repeat the process. The catalytic converter combines hydrocarbons (HC) and carbon monoxide (CO) with oxygen to form
water (H2O) and carbon dioxide (CO2).
Catalytic Converter
The catalyst is structured in the form of a honeycomb monolith. The catalyst consists of a porous substrate of an inert material, coated with platinum and
other metals, the catalytically active materials. This device, located in the exhaust system between the exhaust manifold and muffler, requires the use of
heat shields due to its high operating temperatures.
The heat shields are necessary to protect chassis components, passenger compartment and other areas from heat related damage.
