What does it mean when the Great Wall pickup's particulate filter is self-cleaning?
2 Answers
The meaning of the Great Wall pickup's particulate filter self-cleaning is that the vehicle has automatically initiated the regeneration process, which fully burns off particulate matter to restore the DPF's ability to continue capturing particles. Below is a detailed introduction about Great Wall Motors: 1. Overview: Great Wall Motors is a Chinese automotive brand established in 1984, headquartered in Baoding, Hebei Province, mainly producing SUVs, sedans, pickups, and new energy vehicles. It is the first privately-owned automotive enterprise listed on the Hong Kong H-share market, the largest specialized manufacturer of SUVs and pickups in China, and a multinational corporation. 2. Others: Its brands include Haval, WEY, ORA, Tank, and Great Wall Pickup. Great Wall Motors adheres to an "over-investment" strategy in technology R&D, focusing on effective research and pursuing leadership.
I've driven diesel pickup trucks for years and know all about the DPF regeneration process. The Diesel Particulate Filter (DPF) is an environmental device in vehicles designed to capture soot particles from exhaust gases, preventing air pollution. However, when too many particles accumulate over time, it can clog and affect performance. Regeneration is the system's automatic high-temperature combustion process: the engine raises temperatures to over 600 degrees Celsius, burning the accumulated particles into ash and clearing the filter. This usually happens during highway driving—for example, a few minutes after entering the freeway, the dashboard will display a regeneration prompt. This isn't a malfunction but a normal functional design, common in diesel vehicles like Great Wall pickups. No need to worry, but avoid shutting off the engine during regeneration, as it may interrupt the process and lead to more complex issues. I've encountered a few instances where the system showed regeneration failure during city traffic jams, requiring a stretch of highway driving to complete the cycle. Regular maintenance is key—using the right engine oil and diesel additives can reduce regeneration frequency, with general checks recommended every 5,000 kilometers. Overall, regeneration extends the device's lifespan and keeps the pickup running smoothly.
