DPF filter – what is it and what is it for?
Back in 1969, Daimler-Benz developed the first “soot filter” based on fibrous materials and tested in commercial vehicle exhaust systems, together with the German company MANN & HUMMELIN. The purpose in the initial phase of the development of this filter was to keep larger soot particles in the exhaust system, since it has been proven that such particles cause serious health problems.
According to statistics, as many as 91% of the world’s population lives in places where the concentration of pollutants in the air exceeds the limit values. Therefore, over the years, new technologies and devices have been developed in order to meet the increasingly stringent requirements of nature protection. Today’s vehicles pollute the air as much as 95% less than in the 1970s.
One of the technologies for reducing environmental pollution are DPF filters (Diesel Particulate Filter) that have evolved over time – from fiber-based filters to very complex ceramic exhaust gas flow systems, with one goal – to separate all solid particles that pollute the environment and which are dangerous to our health. Such filters do their job well… until they fill up!
Why is it important to use adequate and high quality motor oil?
Car manufacturers with DPF filters are introducing a filter regeneration process that cleans and empties the filter full of solid particles. It is in this process that adequate and quality motor oil plays a very important role. The process of the regeneration process begins by raising the temperature to the limit at which concentrated soot particles burn. One way to achieve this is to inject a larger amount of diesel fuel and discharge it with exhaust gases into the DPF.
This process causes two problems: engine oil enters the DPF along with the fuel and diesel fuel enters the oil sump. Mixing diesel fuel with engine oil reduces the viscosity of the oil, which is why such oil cannot protect engine components and lubricate them properly. It will also cause a significant drop in oil pressure with side effects on engine performance. So, those small amounts of fuel that go into the crankcase cause dilution and decomposition of the oil, which means that the oil loses its lubricating properties, removes heat less and does not protect engine parts from corrosion! Therefore, all engine oils compatible with the DPF filter must have the additional ability to retain all their properties with the effect of diluting the oil with fuel.
In addition, engine oil with a high percentage of sulfate, phosphorus and sulfur (SAPS) will not only affect the operation of the DPF filter, but will also clog the particle filter and reduce its capacity. For this reason, all engine oils must be compatible with the DPF filter, which means that they must have low levels of sulfate, phosphorus and sulfur.
MOTUL 8100 motor oils are of high quality, and some are formulated to be fully compatible with DPF filters.
If you want to protect your car’s engine and extend the life of your DPF filter, use high-quality engine oil that is compatible with the DPF filter!
