DPFs are devices fitted along the exhaust pipe which are designed to remove soot or particulate matter from the exhaust gas from a diesel engine. The diesel particulate matter is what gives diesel exhaust fumes a dark heavy smoke. The soot is the by-product of incomplete combustion of diesel within the engine. Depending on the type of DPF fitted on a diesel engine vehicle 85% to 99% of soot can be filtered from the exhaust fumes. It therefore enables the exhaust pipe to emit none visible fumes.
The efficiency of these filters depends on the materials used in their manufacture. Common materials used in the manufacture of DPFs include silicon carbide, ceramic fibre, cordierite and metal fibre. The material used also affects the price of the filter.
Like with any other filter DPFs might become clogged with the particulate matter over time. As such, they need to be emptied. DPFs are designed to get rid of the soot in environmental friendly ways. This is through a process called regeneration where the diesel particulate matter is burned off at high temperatures leaving ash residue. Modern cars are designed to burn off soot through active regeneration where the vehicles computer system triggers the production of heat to burn off the soot.
Emissions from diesel engines have been linked to environmental pollution. In particular, diesel particulate matter contributes to air pollution. Once the particulates are airborne, inhalation can result in lung and heart problems.
The law doesn't require that you fit a diesel particulate filter in your car. However, standards have been set to control the emissions from diesel engine vehicles. Currently in the United Kingdom, the Euro 5 standard applies. This standard also applies to all members of the European Union.
The Euro 5 standard requires that diesel particulate emissions do not exceed 5mg per kilometre. It also sets the maximum amount of carbon monoxide emissions from such engines at 500mg per kilometre. The maximum amount of combined nitrogen oxides and hydrocarbons per kilometre is set at 230mg. The London Low Emissions Zone is another standard set to reduce the amount of particulate emissions within London.
These standards target car manufacturers. However, having your vehicle fitted with a DPF is the best thing to do in order to keep the environment clean.
