Fit for Diesel Sport Vehicle Catalytic Converter Euro IV

How do Catalytic Converter And Mufflers work?

Modern cars feature Three Way Catalytic Converter to handle emissions: nitrogen oxide (NOx), hydrocarbons and unburnt fuel.  Ceramic blocks lined with precious metal catalysts – platinum, rhodium and palladium – provide an extremely large surface area for gases to pass over and trigger chemical reactions that reduce harmful pollutants while making your car run cleaner.

 

Exhaust Pipe Catalytic Converter use sophisticated chemical processes to store and release oxygen efficiently.  Their catalysts utilize advanced chemical principles to do just this, operating best when an engine operates within a narrow range of air/fuel ratios near stoichiometric point.  If too lean of an air/fuel ratio occurs, its ability to reduce NOx drops dramatically;  to maintain maximum effectiveness oxygen sensors on modern cars monitor this ratio continuously to signal catalytic converters to oscillate between rich and lean conditions for maximum reduction efficiency of NOx, HC and CO reduction efficiency of 98%!
