Why doesn't the Volkswagen 380 have a particulate filter installed?
2 Answers
Volkswagen 380 does not have a particulate filter installed because: the 380 is a 7-seater and does not require a particulate filter. Below is an introduction to the functions of a particulate filter: 1. Regeneration function: It can effectively reduce the emission of particulate matter by first capturing the particulate matter in the exhaust gas and then oxidizing the captured particles to regenerate the particulate filter, reducing the soot produced by diesel engines by more than 90%. The captured particulate emissions are subsequently burned off during vehicle operation. 2. Purification function: After the purification cycle is completed, any remaining dust or residue will ultimately be manually removed during routine maintenance. With the help of the engine control system, it not only controls the amount of particulate emissions but also the emissions of pollutants such as hydrocarbons and polluting gases.
As someone who frequently deals with Volkswagen vehicles, I can tell you that the early versions of the Volkswagen 380TSI, such as those before the China V emission standards, did not come equipped with a particulate filter. The main reason was that regulations at the time only mandated the installation of DPFs (Diesel Particulate Filters) for diesel engines, while gasoline engines emitted fewer particulates and were not strictly required to have GPFs (Gasoline Particulate Filters). Volkswagen prioritized cost and performance optimization, designing the engine to reduce particulate emissions through improved combustion systems, thereby avoiding the installation of a GPF to minimize weight and backpressure effects. However, with the introduction of the China VI-B standards, all gasoline vehicles are now required to have GPFs to control pollution, so newer models are universally equipped with them. If your car is a used older model purchased before 2018, it might not have a GPF, but don’t worry—those cars are simpler to maintain, though they are slightly less environmentally friendly.
