What is a diesel particulate filter? Is it important for cars?

All new diesel vehicles are equipped with diesel particulate filter (DPF). We explain what it is and why we need your car and clean the DPF. Generally speaking, you don't need to know the engineering design of cars, but if you drive the latest diesel models, it may be helpful to know DPF. This abbreviation refers to diesel particulate filter. As the name implies, this is to prevent automobile exhaust from emitting small and toxic particles. However, many DFP working modes may cause problems if specific preventive measures are not followed.

What is DPF and why should I know? Especially the owners of diesel vehicles, or they will hurt their cars. What is a DPF filter? Unlike gasoline engines, diesel engines burn fuel, so as a by-product of the combustion process, they produce a lot of smoke and dust. This beautiful and almost invisible substance will bring great health problems to the environment. The job of DPF is to destroy and destroy DPF before possible things happen. DPF became the standard in 2009, but before that, some diesel vehicles had already installed this technology.

Clean DPF

The primary task of DPF is to capture and suppress harmful particles, and at the same time, to get rid of them. DPF realizes this process by burning at extremely high temperature and converting particles into harmless ashes, which is called DPF regeneration. Reasons why DPF regeneration and diesel oil are harmful to short-distance travel

DPF can be started in many ways, but it usually needs exhaust gas to get quite high heat, that is, twice the heat of a domestic oven, about 500 degrees Celsius. Driving a car at a speed of 40 miles per hour for a few minutes will lead to "manual regeneration", which will automatically remove particles from DPF at regular intervals.

However, many drivers who live in cities or only drive short distances will not raise the exhaust temperature high enough to "passively update". This may lead to soot accumulation, eventually blocking the DPF, leading to engine problems, such as decreased fuel efficiency and fire. Warning lights may appear on the dashboard. If you don't drive at high speed often, the engine will actively regenerate to remove DPF. This is where the engine makes the exhaust gas hot enough to burn soot, and the car doesn't need to drive at high speed.

Unfortunately, active regeneration only happens when the car is running, so city drivers who usually drive while parking will find that their cars can't actively play DPF. Most cars have a two-level early warning system. If you see an amber light, you should be able to drive at 40 miles per hour for about 10 minutes and play DPF. However, if the red DPF warning light is on, it means going to the garage. DPF maintenance

When the DPF indicator light is on, it usually gives a warning that the equipment needs cleaning. Your car manual will tell you how to drive to achieve this goal. According to these instructions, if the indicator light doesn't go out, you should give the car to the dealer as soon as possible. DPF detergent can be bought in auto parts stores, but the jury doesn't care about the effectiveness of this liquid, so it's best to leave DPF cleaning to experts.

According to the serious blockage of DPF, dealers can use special DPF detergent products and technologies. If this service is not provided, please ask if you can uninstall DPF and send it to a professional company for cleaning. This process costs about 100. The garage obviously charges for removing and reinstalling the filter. If you are unlucky, excessive smoke will cause irreparable damage to DPF. In this case, it needs to be replaced, and the cost of replacing DPF may exceed 1000. But buying after-sales DPF can save some money.

Do you need to consider DPF?

Many immoral people suggest getting rid of your car, but this is only the end. Not only will you cause unnecessary damage to the environment, but your car will automatically fail in the MOT test. Finally, if you have a diesel car, make sure you know how to regenerate DPF. Therefore, as long as you see the warning light coming on. Parking (all you have to do is read the manual) will further aggravate the congestion.
