1. Fuel filter: Two-stage precision filtration system (precision 5–10 microns), compatible with National VI low-sulfur diesel (sulfur content ≤10 ppm).
2. Air filter: High-efficiency filtration module (efficiency >90%). In desert regions, inspect every 30 hours; in high-altitude areas, reduce the maintenance cycle by 10% for every 1,000-meter increase in altitude.
