Does the Volkswagen CC Shooting Brake have a particulate filter?
1 Answers
Volkswagen CC Shooting Brake is equipped with a particulate filter. The Diesel Particulate Filter (DPF) is a ceramic filter installed in the exhaust system of diesel engines, which captures particulate emissions before they enter the atmosphere. Its function is to filter out tiny particles in the exhaust gases. When a certain amount of particles accumulates, it automatically burns off the captured particles, thus achieving a continuous working cycle. The diesel particulate filter effectively reduces particulate emissions by first capturing the particles in the exhaust and then oxidizing them to regenerate the filter. The regeneration of the filter refers to the process where, during long-term operation of the DPF, the accumulation of particles gradually increases the backpressure in the engine, leading to a decline in engine performance. Therefore, it is necessary to periodically remove the deposited particles to restore the DPF's filtering performance. A clogged particulate filter can reduce vehicle power. Some vehicle models, upon detecting a clogged particulate filter, will automatically reduce the power output of the diesel engine. Additionally, significant exhaust resistance can also weaken the vehicle's power performance.
