Description of Cordierite Diesel Particulate Filter:

Silicon Carbide or Cordierite Diesel Particulate Filter is installed in the exhaust system of a diesel engine and uses a wall-flow method to filter particulate five (PM) with a removal efficiency of up to 98%. It is an effective means to control the black smoke phenomenon of exhaust gas, and it can also greatly reduce noise pollution. We can produce various types of traps with a hole density of 100 mesh and 200 mesh. The products can reach EURO v, EURO vi, EPA and other emission standards, and can be widely used in diesel vehicles and general machinery.

Performance Characteristics of Cordierite Diesel Particulate Filter:

  1. The black smoke treatment and deodorizing effect are obvious, and the opacity is close to zero
  2. The filter element used in the system has a long service life
  3. The purification system is automatically started, controlled and easy to operate
  4. Intelligent regeneration control system to reduce energy consumption
  5. The structure is sturdy, and the shell package is not modified
  6. Assembled structure, easy to install

DPF Regeneration Function:

There are two types of DPF regeneration: passive and active.

Passive regeneration

When a car is driving at a high speed on a long-distance highway, passive regeneration occurs, which causes the exhaust gas temperature to rise to a higher level and cleanly burns the excess smoke in the filter.

Therefore, it is recommended that drivers regularly drive diesel vehicles on highways or A roads at a continuous speed for 30 to 50 minutes to help clear the filter.

However, not all drivers perform this type of driving on a regular basis-this is why the manufacturer devised another form of regeneration.

Active regeneration

Active regeneration means that as part of the vehicle’s ECU, when the filter reaches a predetermined limit (usually about 45%), it will automatically inject additional fuel to increase the exhaust temperature and burn off the stored soot.

However, if the journey is too short, problems may arise because the regeneration process may not be completed completely.

If this is the case, the warning light will continue to show that the filter is still partially blocked.

In this case, it should be possible to complete the regeneration cycle and clear the warning light by driving at a speed of more than 40 mph for about 10 minutes.
