How long does the self-cleaning of the Great Wall Pao's particulate filter take?
1 Answers
The self-cleaning of the Great Wall Pao's particulate filter typically takes around 5-10 minutes. Below are the precautions to note during the self-cleaning process: When the vehicle is undergoing the regeneration procedure, the owner must not turn off the engine, as the cleaning of the particulate filter requires raising the exhaust temperature to burn off the particulates inside the filter. Turning off the engine would prevent the cleaning process from being carried out. If the engine is accidentally turned off, the owner simply needs to restart the engine to initiate the regeneration procedure again, without worrying about causing any adverse effects on the vehicle. Below are the common reasons why the particulate filter gets clogged frequently: 1. Poor fuel quality: Prolonged use of fuel with high impurities can not only clog the engine injectors but also increase exhaust particulates, leading to clogging of the particulate filter. 2. Not using specialized engine oil: National VI vehicles require the use of low-ash engine oil. Failure to use low-ash engine oil increases the likelihood of the DPF (Diesel Particulate Filter) getting clogged. 3. Prolonged idling: Idling can cause carbon buildup in the engine, and at the same time, fuel cannot be completely burned during idling, leading to an increase in exhaust particulates. In such cases, the DPF is very prone to clogging.
