Will the Particulate Filter in Audi Vehicles Get Clogged?
1 Answers
If driven frequently on short trips or for extended periods in congested traffic conditions, there is a risk of the particulate filter in Audi vehicles becoming clogged. The effects of a clogged particulate filter include reduced engine power output, as well as increased exhaust backpressure, which can weaken the vehicle's performance and raise fuel consumption. When the particulate filter warning light appears on the dashboard, it is necessary to clean the filter. The solution for a clogged particulate filter is to shift the car into S mode and drive at high speeds for a period of time. During high-speed driving, the exhaust pipe temperature rises, allowing the trapped particles in the filter to burn off, thereby resolving the clogging issue. The principle of the particulate filter involves coating the diesel particulate filter with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the particulate filter through a dedicated pipe. The densely arranged bag-type filters inside capture the carbon particles on a metal fiber felt filter. Once the accumulated particles reach a certain level, the burner at the end automatically ignites, burning off the trapped carbon particles and converting them into harmless carbon dioxide before being released.
