Diesel particulate filter regeneration system
WebThe Cummins Particulate Filter contains the Diesel Particulate Filter (DPF) which collects and oxidizes carbon to remove particulate matter (PM) by more than 90%; the Diesel Oxidation Catalyst (DOC) aids in this process and is also contained in the Cummins … Cummins develops industry-leading aftertreatment technology designed to … WebA diesel particulate filter (DPF) is a filter that captures and stores exhaust soot (some refer to them as soot traps) in order to reduce emissions from diesel cars. But because they only have a finite capacity, this …
Diesel particulate filter regeneration system
Did you know?
Filters require more maintenance than catalytic converters. Ash, a byproduct of oil consumption from normal engine operation, builds up in the filter as it cannot be converted into a gas and pass through the walls of the filter. This increases the pressure before the filter. Warnings are given to the driver before filter restriction causes an issue with driveability or damage to the engine or filter develop. Regular filter maintenance is a necessity. WebThermal regeneration of diesel particulate filters involves the oxidation of solid particulates to gaseous products, preferably to CO 2. Depending on the DPF system design and on the engine operating conditions (exhaust …
