DIESEL PARTICULATE FILTERS (DPF)
Roadwarrior DPFs contain a cordierite filter with alternately plugged channels. The exhaust gas is forced to flow through the filter walls, trapping particulate matter such as soot, hydrocarbons, and lube oil ash, and allowing exhaust gas to pass through.
DIESEL OXIDATION CATALYST (DOC)
In many 2007 and later model year heavy duty trucks, the DOC plays a key role in the thermal management of the DPF. A small amount of fuel is injected in front of the DOC on a period basis, which is then combusted on the DOC and allows the release of heat for the regeneration of soot in the DPF.
SELECTIVE CATALYST REDUCTION (SCR)
The SCR is an advanced active emission control technology system that injects a liquid reducing agent through a special catalyst into the exhaust stream of a diesel engine. The source of reductant is typically automotive grade urea, also known as Diesel Exhaust Fluid (DEF).
A modern diesel aftertreatment system known as the “One-Box”. While meeting the requirements of emissions regulators such as the EPA, the best thing about One Box is that it is a compact assembly that includes all the components in a small box efficiently!
