Does Lexus Have a Particulate Filter?

[VanChase]

Lexus has a particulate filter. 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. 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 engine exhaust particulate trap through a dedicated pipeline. It passes through the densely arranged bag-type filters inside, which adsorb the carbon soot particles onto filters made of metal fiber felt. When the amount of adsorbed particles reaches a certain level, the burner at the end automatically ignites, burning off the carbon soot particles adsorbed on it and converting them into harmless carbon dioxide that is then expelled.
