What is a diesel particulate filter?

Many cars have diesel particulate filters. The particulate filter can be a dye for automobile filtration. It is very important to quickly remove dust from the air to avoid polluting diesel oil. However, many car owners are not satisfied because the particle filter is always blocked.

1. What is a diesel particulate filter? In special vehicles, the engine is regarded as the "heart" part of the vehicle, so the diesel filter is the "kidney" part of the vehicle, and the human kidney plays a role in filtering blood. The diesel filter of special vehicles is the filtered fuel. Because the impurities deposited in the fuel system and the dust suspended in the air will pollute the diesel and the quality of the diesel itself, the diesel filter on the special vehicle is essential.

2. Can the National Six Particle Trap be dismantled? ?

At present, most of the gasoline vehicles in the sixth country are equipped with particle traps, and sometimes there is only one particle trap for the vehicles that emit the tail gas of the fifth country and the sixth country. If the particle trap is disassembled, the tail gas will fail in the audit last year, which will be very uneconomical. Although the particle trap will slightly reduce the output power of the vehicle, the overall impact is not great, and we don't need to disassemble it. For diesel vehicles, it may not be necessary to disassemble the particle trap, because the particle trap has a great influence on the emission of diesel vehicles.

3. Working principle of particle trap When the exhaust temperature is high, GPF burns soot particles. By controlling the air intake and fuel injection in the engine cylinder, the temperature in the particle trap can be increased, so that carbon particles can react with oxygen to burn, and soot particles can pass through the complete combustion regeneration cycle at high temperature. Without GPF, these particles will be directly discharged into the atmosphere, causing air pollution.
