DIESEL ENGINE

5.9L DIESEL ENGINE

Exhaust gases travel from the engine turbocharger through the front exhaust pipe into the Catalytic Converter which treats the exhaust gas by converting harmful carbon monoxide, unburned hydrocarbons and other compounds into water, carbon dioxide and heat.

The exhaust gases are then forced through the muffler for noise control. From the muffler the exhaust gases flow through the tail pipe and out into the ambient atmosphere.

6.7L DIESEL

Exhaust gases travel from the engine turbocharger through the front exhaust pipe into the exhaust system After treatment. The After treatment consists of the Diesel Oxidation Catalyst (DOC) and a Diesel Particulate Filter. The DOC treats the exhaust gas by converting harmful carbon monoxide, unburned hydrocarbons and other compounds into water, carbon dioxide and heat.

The partially treated exhaust gases from the DOC flow into the catalyzed Diesel Particulate Filter (DPF) which traps and accumulates particulate matter (soot) and further treats the exhaust gases to reduce harmful compounds. The trapped particulate molecules will be periodically removed from the DPF through a thermal regeneration process initiated by the engine's electronic controls.

The exhaust gases are then forced through the muffler for noise control. From the muffler the treated exhaust gases flow through the tail pipe and out into the ambient atmosphere.
