Why does the Volkswagen 380 not have a particulate filter?

The reason why the Volkswagen 380 does not have a particulate filter is that the 380 version is equipped with a high-power 2.0L engine, while the 330 version with a particulate filter is a low-power 2.0L version. If there is a problem with the particulate filter, the vehicle's fuel consumption will increase. Function of the particulate filter: The particulate filter can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Principle of the particulate filter: The diesel particulate filter is coated with platinum, rhodium, and palladium metals. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate trap through a special pipe. After passing through the densely arranged bag filters inside, the carbon particles are adsorbed on the filter made of metal fiber felt. When the amount of adsorbed particles reaches a certain level, the burner at the end automatically ignites and burns, turning the adsorbed carbon particles into harmless carbon dioxide that is then discharged.
The Volkswagen 380 does not have a particulate filter, which is related to emission regulations. With years of experience in car repair, I've observed that in regions with lower emission standards, such as certain areas, the engine's higher combustion efficiency alone can pass inspections, allowing Volkswagen to omit this component. A particulate filter is a device that captures tiny particles from exhaust gases. Installing it would increase weight and cost, and it might also clog, leading to higher fuel consumption. Without it, the car is lighter and more agile, maintenance is simpler, and it saves some money. However, it's important to note that as regulations tighten in the future, similar to those in Europe, it will likely become mandatory to install one. Users should prepare early to avoid complications. Currently, Volkswagen is optimizing engines to reduce pollution, but this is not a long-term solution. Under the trend of environmental protection, changes will inevitably come.
