Operation logic：
Smoke purifier constantly collects carbon ash at work, and the accumulation of DPF carrier insides soot particulate matter is more and more, slowly
Micropore (micropore is located at around sealing device) on DPF carriers can be blocked, and exhaust back pressure continues to increase, now from hole
Gas exhaust pressure act on sealing device, the sealing plate of sealing device is gradually increased by gas pressure intensity, when pressure produce
After raw pressure exceedes the pressure of compression spring pre-set, after can compression spring, sealing device will be with DPF carrier tables
Face is separated, and gas is discharged from Separation, and engine exhaust back pressure moment reduces, and makes engine big because of exhaust back pressure
Blocked completely, avoid engine damage.The gas now gone out from hole is just become without by filtering, gas color by white
For black, alarm function is played, now needs to remove in DPF carriers, passes through the carbon ash inside manual method cleaning.
The design principle of product is that the centre bit in clarifier product DPF carriers one end is equipped with a bit of straight-through area,
