Case Study
Stage 1 · Customer Problem
📋 Customer Problem
A Northwest mining company focused on mineral resource extraction operates in a typical Northwestern environment characterized by arid conditions, heavy windblown sand, and large temperature variations, with long and complex logistics supply chains. In the field operating environment, fuel management faces demanding challenges:
🌪️
Harsh Fueling Environment
Windblown sand is severe at field sites. During open-air fueling, large quantities of dust particles easily mix into the fuel tank, contaminating diesel at the point of use.
🛢️
Fuel Quality Fluctuation
Due to the remote location, diesel at the supply chain terminal often contains substandard impurities and gums, inconsistent from batch to batch.
⚙️
Frequent Core Component Damage
Dirty diesel causes precision HPCR injector nozzles of construction machinery to suffer frequent wear and clogging, resulting in high repair costs.
📉
Low Operational Efficiency
Insufficient engine power, black smoke, and frequent failure repairs affect the mining progress and overall productivity.
Stage 2 · Fuel Analysis · NEW
🔬 Fuel Analysis
Fuel sampling from field fueling operations revealed contamination levels far exceeding engine manufacturer specifications, with the Northwestern arid environment contributing heavy sand dust and extreme temperature swings causing condensation:
| Metric | Before Treatment | After Treatment | Improvement |
|---|
| ISO 4406 Cleanliness | ~24/22/19 | 13/10/7 | 5-6 levels ↑ |
| Free Water (ppm) | ~140 | ≤50 | 64% ↓ |
| Visual Appearance | Dark, cloudy with visible sand particles | Clear, bright | — |
| TAN (mgKOH/g) | 0.16 | 0.06 | 63% ↓ |
| Particle Composition | Windblown sand, mineral particles, dust | ≥99% removed at ≥3 μm | 99% ↓ |
Values are representative of the Northwest arid mining environment with heavy windblown sand and extreme temperature variations causing condensation in storage tanks. The portable unit moves with fueling trucks to any field operation point, completing purification during diesel injection. Post-treatment ISO 13/10/7 exceeds typical engine manufacturer requirements (ISO 18/16/13).
Stage 3 · Solution

💡 Lessons Learned
✅
Key Success Factor
The portable design was the critical decision for the Northwest mining operation's dispersed field fueling points. Unlike stationary systems, the JY-219A follows fueling trucks to any location, completing real-time purification during diesel injection. The "fuel while traveling, real-time purification" approach ensures cleanliness at the actual point of use, regardless of how remote or dusty the fueling location. The rugged structure withstands windblown sand and extreme temperature variations.
⚠️
Common Pitfall
Northwestern mining environments have extreme day-night temperature swings that cause condensation in storage tanks, introducing free water into diesel. Standard filtration approaches focus only on particulate removal and ignore water, leading to tank corrosion and microbial growth. Windblown sand during open-air fueling adds contamination that stationary systems at the main storage tank cannot intercept. Without point-of-use portable purification, fuel is recontaminated between the storage tank and the machinery.
🔄
Replication Advice
Ideal for all field and arid mining operations with dispersed fueling points where stationary systems are impractical. The portable approach is essential for operations where fueling trucks move between multiple remote sites. The rugged, all-weather structure is critical for environments with windblown sand and extreme temperature variations. For large operations, deploy multiple JY-219A units across different fueling teams for comprehensive coverage.

Customer feedback
In the desert mining area of the Northwest, dust is everywhere, and fuel quality is hard to guarantee. Jingyuan's JY-219A changed our situation. It is light and portable enough to follow the fleet anywhere. Since we started purifying fuel at every fueling, injector nozzle failures have decreased significantly, and the saved fuel costs effectively cover the equipment cost. This is a reliable quality assurance for our heavy machinery.
