Due to the high petrol prices and adequate performance, diesel vehicles have always been a more friendly option for people’s pockets. But what about the dreaded DPF filter?
Your vehicle’s particulate filter removes diesel soot from the exhaust gas of a diesel engine, and like any other filter, it slowly gets clogged up with the soot that it traps.
When you buy a diesel car, you think: ‘come on, the DPF located within my car’s exhaust system regenerates automatically, which is why this filter will never trouble my ride.’ Well, do you know that a DPF needs high temperatures to self-clean automatically? Low mileage and short journeys will leave you distressed with a blocked DPF. Let’s list down our top 4 causes of DPF failure:
Regular Short Start-Stop Journeys
Repeated short drive times at less than highway speeds is a practical reality in today’s world, where the roads witness high traffic, red lights and brake lights.
A good DPF regeneration takes place at a higher engine speed and with the kind of driving that most people are bound to practice, the vehicles probably never gets hot enough to regenerate.
The worst part is: when you drive with a dirty filter, your engine works harder than it should be; so, unfortunately, you have to experience less power, poor fuel economy, and more damage.
Wrong Engine Oil
Many people use standard engine oil for their vehicles. However, this is a wrong doing. Vehicles fitted with DPF’s are special vehicles that require a Low or Mid SAPS engine oil. SAPS means “Sulphated Ash, Phosphorous, and Sulphur.” A low SAPS engine oil has a smaller quantity of Sulphated Ash, Phosphorous, and Sulphur, preventing the DPF filter from becoming prematurely blocked.
Issues with EGR
An anti-pollution device, the Exhaust Gas Recirculation (EGR) valve is designed mainly for minimizing the amount of nitrogen oxide (NOx) emitting out of the vehicle’s exhaust pipe.
The carbon dust inside the exhaust gasses clogs up the EGR system, reducing the movement of EGR valve. Due to this, the engine doesn’t function properly, leading to inefficient fuel consumption and more carbon dust production.
Soon, this causes a DPF to become jammed.
Mind you; good quality turbochargers rarely become faulty. Let’s get this clear: without the correct operating conditions, these components will perform ineffectively.
So, if there’s a turbo failure, your diesel engine will produce more of the revolting black soot than the usual. In such a scenario, a faulty turbocharger will also be responsible for the leakage of a huge amount of oil into the fuel system, further leading to the DPF being drowned in an ocean of engine oil.
