LAYOUT OF THE EMISSIONS CIRCUIT The complex pollution control circuit that clutters the outside of a diesel engine built after 2010 makes it highway-compliant. On today's highway diesels, DPF and SCR are virtually always utilized. Without SCR, one must rely...

EPA Compliance Instructions An SCR management strategy must include the following, per the EPA: Low DEF reservoir alerts are sent by the driver warning system. Measures to entice drivers: a cap on restarts, a fuel lockout mechanism, or engine deceleration until the...

SELECTIVE CATALYTIC REDUCTION (SCR) Selective catalytic reduction (SCR), a method of exhaust gas aftertreatment, is comparable to DPFs. An SCR system aims to "reduce" NOx back to nitrogen and oxygen while the DPF deals with particulate HC. SCR has been used for more...

NONCATALYZED DPFs Occupational diesel engines with highway certification that are operated for extended periods of time at low engine load must have noncatalyzed diesel particulate filters (NC-DPFs). This kind of application is unique in that exhaust temperatures...

DPF Cleaning Period   Ash remains are left over after regeneration. These ashes largely come from the engine lubricant additive package that burns in the cylinder during regular combustion. Ash residues must be carefully removed. This cleaning procedure must be...

Regeneration Rate Regeneration cycles are planned to happen on a regular basis. Depending on the engine, its power ratings, how the engine is being driven, and the kind of DPF, these predetermined intervals may occur as frequently as once every hour or as infrequently...

Different DPFs Our main goal in this part is to concentrate on the post-2007 DPFs that are required. The type of DPF employed on a certain diesel engine is mostly dependent on the typical exhaust temperature. Three different forms of DPF are often in use: A catalyst....
