Maintenance and upkeep standards for plateau DPF
1. Fuel and oil selection
Fuel standard: National VI B diesel (sulfur content ≤ 10ppm) must be used; Recommend adding fuel additives containing DPF cleaner (such as BASF G3659);
Oil requirements: viscosity grade: 5W-30 (for high-altitude areas); Ash content: ≤ 0.8% (avoid CK-4 or higher grade engine oil).
2.
Maintenance Interval | Inspection Items | Standard Values |
Every 10,000 kilometers | DPF differential pressure sensor | signal voltage is 0.5-4.5V |
Every 20,000 kilometers | Activity of the DOC catalyst | NOx conversion rate are both ≥75% |
Every 30,000 kilometers | Carbon buildup inside the DPF | should be ≤5g/L (as determined through endoscopy) |
3. Handling of vehicles parked on high plateaus for extended periods of time
Pre parking operation: Perform a complete regeneration cycle once; Spray DPF moisture-proof agent (such as Walter 8933001);
Operation after restart: Preheat DPF by driving at low speed for 10 kilometers; Check if there is a P2463 (particulate matter accumulation) alarm on the dashboard.
