Its Most important purpose is to reduce destructive emissions of hydrocarbons, carbon monoxide, and nitrogen oxides by changing them into significantly less harmful substances including drinking water vapor and carbon dioxide as a result of chemical reactions.
By no means use water or steam cleaners on hot DPFs to stop thermal shock hurt, and refrain from banging about the housing.
Check for visual smoke and dash warnings, and watch fuel financial system weekly. Evaluate backpressure after oil changes. This catches concerns early in advance of key clogging occurs.
As diesel exhaust passes with the filter, soot particles become trapped inside the partitions. Underneath normal driving disorders, these trapped particles are “burnt off” by DPF regeneration, where exhaust temperatures get to above 600°C.
