These are mainly found in diesel vehicles. The particle filter is designed to catch soot particles inside. Later, when the particulate filter becomes clogged, the soot undergoes a chemical breakdown process called pyrolysis. DPFs are designed to trap and store particulate matter, such as soot, that is produced by the diesel engine during normal driving. The DPF allows exhaust gases with particulate material to enter the DPF where the soot is trapped inside the filter, allowing cleaner exhaust gases to exit into the atmosphere, which then reduces the exhaust Fortunately, there is an easy way to clean a DPF !
