Diesel Particulate Regeneration
Diesel Particulate Regeneration in Erith - Apollo Autos
The increase in the popularity of diesel powered vehicles is well documented and the reasons for the increase in the popularity over recent years is that diesel engines unlike in the past have evolved to now perform more like the traditional petrol engines, with the added benefit of vastly improved fuel economy.
The disadvantage of this however is diesel exhaust emissions (Black Smoke). Diesel fuel is derived from a form of heating oil, this does not allow for an environmentally friendly engine.
To improve the efficiency and exhaust gas emissions on modern diesel engines manufacturers are now fitting Diesel Particulate Filters (DPF) to modern diesel engines.
The DPF is fitted in the vehicle’s exhaust system and catches or collects exhaust gases and soot particles from the engine reducing exhaust gas emissions, as with all filters they need to be cleaned from time to time to prevent blocking. DPF is designed to be cleaned by the vehicle under certain driving conditions; this is normally at freeway speed. If the filter is not cleaned it will eventually block causing operating problems with the vehicle.
The introduction of DPF on diesel engines has caused problems with vehicles that only travel in urban cycles and often do not travel at motorway speed, for the vehicle to effectively clean the D.P.F the vehicle is required to travel at motorway speed for a period of time to allow the regeneration process. If this is not carried out eventually the D.P.F will become blocked and cause the vehicle to become underpowered and in some cases stop.
