6.7L DIESEL





WARNING: The normal operating temperature of the exhaust system is very high. Therefore, never work around or attempt to service any part of the exhaust system until it is cooled. Special care should be taken when working near the catalytic converter or DOC/DPF. The temperature of these units rises to a high level after a short period of engine operation time.

The DR Aftertreatment consists of two inline catalytic converters and a combination diesel oxidation catalyst (DOC)/Diesel Particulate Filter (DPF). The diesel oxidation catalyst (DOC) is a ceramic flow through substrate coated with a catalyst washcoat that is integral to the DOC/Diesel Particulate Filter (DPF) assembly. The close coupled DOC treats engine exhaust gases by converting harmful carbon monoxide, unburned hydrocarbons and other compounds into water, carbon dioxide and heat.

The DC/DH Aftertreatment consists of a combination diesel oxidation catalyst (DOC)/Diesel Particulate Filter (DPF). The diesel oxidation catalyst (DOC) is a ceramic flow through substrate coated with a catalyst washcoat that is integral to the DOC/Diesel Particulate Filter (DPF) assembly. The close coupled DOC treats engine exhaust gases by converting harmful carbon monoxide, unburned hydrocarbons and other compounds into water, carbon dioxide and heat.
