Does the BMW 125 have a particulate filter?
1 Answers
BMW 125 is equipped with a particulate filter. Function of the particulate filter: The particulate filter can reduce soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Technology applied in the particulate filter: The particulate filter utilizes advanced electronic control systems, catalytic coatings, and fuel-additive catalysts. Principle of the particulate filter: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate trap through a dedicated pipeline. After passing through the densely arranged bag-type filters inside, the carbon soot particles are adsorbed onto the filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites, burning off the adsorbed carbon soot particles and converting them into harmless carbon dioxide that is then released.
