How Many Kilometers for One Regeneration Under China VI Standards?

When the vehicle has completely consumed two tanks of gasoline, the regeneration indicator light on the dashboard will illuminate. Regeneration typically takes about 5 minutes, though the required time may vary for different vehicle models. During regeneration, it is advisable to find a well-ventilated and open area. After pressing the regeneration button, the vehicle will automatically increase its RPM to process, requiring no driver intervention. China VIa: China VIa serves as a transitional phase between "China V" and "China VI" standards. China VIa will be implemented for gas-powered vehicles on July 1, 2019, for urban vehicles (such as city buses, sanitation trucks, postal vehicles, etc.) on July 1, 2020, and for all vehicles on July 1, 2021. China VIb: China VIb represents the true "China VI" emission standard. China VIb will be implemented for gas-powered vehicles on January 1, 2021, and fully implemented for all vehicles on July 1, 2023.
I've been driving a China VI diesel vehicle for several years, and the regeneration interval really doesn't have a fixed number—it generally fluctuates between 300 to 1,000 kilometers. For me, driving more on highways, DPF regeneration occurs around every 600 kilometers. But if I mostly drive short trips in the city with frequent traffic jams, it drops to about 400 kilometers. Regeneration is automatically triggered by the vehicle's sensors monitoring particulate accumulation, and usually, an indicator light will come on to show it's in progress. Never turn off the engine or park during regeneration, as this can worsen carbon buildup and easily clog the filter. Regularly driving at high speeds to keep the engine running at higher RPM helps raise exhaust temperatures, efficiently cleaning the DPF and extending its lifespan, while also saving fuel. Just remember to regularly check the dashboard indicator lights and stay alert.
Having been exposed to China VI emission vehicles for just a few months, I've noticed that the regeneration interval is quite flexible, typically initiating automatic regeneration of the exhaust particulate filter between 500 to 1,000 kilometers. This is largely influenced by engine load and driving conditions – maintaining steady speeds on highways can extend the regeneration interval, whereas stop-and-go city driving might trigger it as early as 350 kilometers. It's helpful to refer to the vehicle manual, which indicates that the regeneration process usually takes about 10-30 minutes, during which slight exhaust odor is normal. Ideally, align this with daily driving habits; if frequent short trips dominate your routine, plan more long-distance drives to assist in cleaning, thereby preventing potential maintenance issues down the line.
Working in an auto repair shop, it's common for China VI diesel vehicles to undergo autonomous DPF regeneration every 400 to 800 kilometers. The exact interval depends on the DPF backpressure sensor readings—the ECU initiates high-temperature fuel injection treatment when particulate accumulation exceeds standards. In urban low-speed driving, regeneration occurs more frequently (around 400 km), while highway driving extends it to 700 km. Never stop the engine during regeneration; maintain driving to fully heat the exhaust and clear soot. Owners should regularly inspect filter condition and drive at highway speeds at least weekly to effectively reduce clogging risks, prolong component lifespan, and maintain environmental compliance.
