What are the issues with the particulate filter in the Tayron?
1 Answers
Particulate filter clogging problem. It can lead to engine exhaust faults and high fuel consumption. 1. The reason for the emergence of particulate filters: In the China VI emission standards, especially with the increased requirements for fine particulate matter (PM) mass and the newly added particulate number (PN) limit, this poses a major challenge for many automakers. This is because with the current generation of high-pressure direct injection engines, fuel is directly injected into the combustion chamber during cold starts at low temperatures, making the power delivery more "direct." However, due to insufficient atomization of the air-fuel mixture, the control over particulate matter is inadequate. 2. The cause of particulate filter clogging: The particulate filter performs "regeneration," which is a self-cleaning function, burning off the internally captured particles under certain operating conditions. Regeneration requires specific conditions. Most vehicles need to operate at high engine speeds to reach the exhaust temperature required for "regeneration." However, many users are unlikely to notice this, as the majority of their driving may be urban commuting, often even at low-speed crawling for distances under 10 kilometers, making it difficult for the particulate filter to meet the conditions for "regeneration."
