Diesel Catalytic Converters Technical Information
The
Selective Burner Substrate starts the process by the selective burning of larger
particulates. This burning also helps start the catalytic reduction
process of NOX as well as CO and HC conversion in the Primary Converter.
The Primary
Converter continues the NOX, HC, and CO reduction and conversion and aids in the
light off of the Clean Up Converter substrate.
The Clean Up
Converter substrate finishes any reduction and conversion that still needs to be
done as well as finishing the Particulate Matter reduction.
The Special
Silica Carbide substrate lights off faster, retains heat longer and by virtue of
its flow characteristics, helps to reduce NOX and Particulates.
