Why does the Tiguan L380 not have a particulate filter?
1 Answers
Due to the fact that the Tiguan L380 version is equipped with the EA888-DKX 2.0T high-power engine, this power configuration adopts a four-way catalytic converter setup. Moreover, since this engine meets the current PN11 standards and also complies with the China 6B emission standards, the Tiguan L380 version does not come with a particulate filter. Basic working principle of a particulate filter: For example, a diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by a diesel engine enters the engine exhaust particulate filter through a dedicated pipeline. After passing through the densely arranged bag-type filters inside, the carbon smoke particles are adsorbed onto the filter 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 smoke particles adsorbed on it, converting them into harmless carbon dioxide that is then emitted. Consequences of particulate filter blockage: The gradual accumulation of particles on the particulate filter of a gasoline engine can lead to blockage of the particulate filter, causing poor engine exhaust flow, which in turn results in decreased engine power. Function of the particulate filter: The particulate filter is mainly used to capture particles in the vehicle's exhaust gas to improve the quality of the vehicle's exhaust emissions and reduce air pollution. The particulate filter used in diesel vehicles is called DPF, while in gasoline vehicles it is called GPF, both of which operate on roughly the same principle.
