With the full switch of the National VI standard, a new term has emerged - DPF regeneration. What is regeneration? Why regenerate? How to regenerate? Today, follow in the footsteps of the truck e-family and take you to understand the mystery of regeneration.
What is regeneration
In order to meet the National VI standard for exhaust emissions, an important component of the engine aftertreatment system has been added - DPF (Particle Trap) to capture harmful particles in the exhaust to achieve the effect of reducing PM particle emissions. DPF filters and oxidizes the collected exhaust gases and harmful particles, a process called regeneration.
Why regenerate? When DPF collects enough harmful particles, it can cause DPF to block. Regeneration can effectively maintain DPF unimpeded, prolong service life, and reduce use and maintenance costs.
There are several ways to regenerate
According to the classification of the starting method of the regeneration function, it is divided into active regeneration and passive regeneration, passive regeneration has always been carried out, but if the driver's speed is slow, the DPF temperature is low, the oxidation rate of carbon particles is slow, and the phenomenon of DPF blocking will also occur, at which time we need to solve it through active regeneration.
Active regeneration is also divided into two types, one is driving regeneration, no manual operation, when the vehicle is normally running at a uniform speed, the engine is in the best condition, in this case, DPF can actively regenerate and does not affect driving.
The second is in-situ parking regeneration, is the need for manual operation when the vehicle is stationary for active regeneration, card friends need to confirm that the clutch pedal, brake pedal, accelerator pedal has not been stepped on, confirm that the anti-regeneration switch has not been pressed, this switch if pressed, will lead to active regeneration can not be carried out, the switch is only in the gas station or near the dangerous goods, in order to prevent the exhaust temperature is too high There is a safety hazard to use, normal driving must not be pressed, while the engine idling, long press the two-second DPF idle switch, The engine speed will soar to 2500 rpm to 3000 rpm, keep the engine running until the engine speed returns to idle speed, and the engine can be extinguished after one minute of idle speed, it is worth noting that according to the size of the DPF and the degree of blockage, the length of the parking regeneration time is also different.
If this method does not solve the problem, it means that your DPF harmful substances seriously exceed the standard, you must be service regenerated, card friends need to enter the repair shop, complete the DPF cleaning, and may need to replace DPF accessories in severe cases.
Finally, the truck e family here reminds you that the use of regular diesel, engine oil can effectively protect DPF, reduce the DPF damage rate, I heard that the national six DPF is very expensive, card friends can take good care of yo!
