Why doesn't Toyota use a particulate filter?

[VanRichard]

Toyota does not use a particulate filter because its vehicles are equipped with naturally aspirated engines and hybrid Atkinson cycle engines, while only turbocharged engines require the installation of 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. 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. After passing through its densely arranged bag-type filter, the carbon particles are adsorbed onto a 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 expelled.
