Why doesn't the Volkswagen 380 have a particulate filter installed?

[Reagan]

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.
