Executive Summary
In a rigorous field test conducted with Transportes Azteca, the 360ES-PEM system demonstrated a verified fuel efficiency increase of 16.36% to 20.7% under severe service conditions. Despite the vehicle operating with a “full” double-trailer configuration (65 Tons payload) at low average speeds (28 km/h), the system delivered enhanced torque and optimized combustion, outperforming the standard engineering baseline for the Cummins X15 engine.

360ES-PEM-15L (Patent Pending)
The Challenge: "Severe Service" Conditions
The objective was to validate performance in a high-stress environment where standard diesel efficiency typically collapses.
- Extreme Load (Edible Oil Tankers): The unit operated in a “full” double-tanker configuration transporting Edible Oil. The specific load breakdown confirmed by the fleet consists of 50 Tons of product payload plus 15 Tons of equipment tare weight (Tankers + Dolly), resulting in a 65-Ton gross towed weight.
- Operational Cycle: The average speed was recorded at 28 km/h. According to TMC RP 1108 standards, this low speed creates “Ghost Mileage” (wear and consumption without distance gains), drastically penalizing fuel economy.
- The Baseline: Under these specific conditions, the theoretical engineering baseline for the engine drops to approximately 1.06 - 1.10 km/L.
The Solution: 360ES-PEM Integration
360 Energy Solutions installed the 360ES-PEM-15L onboard hydrogen generation system. The unit features a micro-computer calibrated to the specific fuel map of the Cummins X15 ECU, injecting a precise dosage of H2+O2 to accelerate the flame front and ensure complete combustion.
Key Results (Validated Telemetry)
Phase 1: Maximum Potential (Empty)
After firmware updates and calibration, the unit was tested without a payload to verify stoichiometric balance.
Result: 2.95 km/L (33.9 L/100km) over 500 km.

Phase 2: The "Stress Test" (65 Tons / 28 km/h)
This phase measured real-world performance under maximum load.
| Metric | Industry Standard (Baseline) | With 360ES-PEM | Improvement |
|---|---|---|---|
| Fuel Economy | 1.10 km/L | 1.28 km/L | +16.36% Efficiency |
| Consumption | 90.9 L/100km | 78.0 L/100km | -14.2% Fuel Volume |
Engineering Note: If compared against the calculated “Severe Traffic” baseline of 1.06 km/L, the net efficiency improvement rises to 20.75%.

Historical Reference (Pre-Calibration)
Historical data analysis shows previous performance over long-haul routes (1,370 km), providing a broad context for the unit’s operation prior to the final optimization phase.

Operational Impact & TCO (Total Cost of Ownership)
Projected Round Trip Performance
By analyzing a complete cycle (500 km Loaded + 500 km Empty), the fleet achieves a highly profitable combined average:
- Leg A (Loaded 65t): 1.28 km/L
- Leg B (Empty): 2.95 km/L
- Global Cycle Average: 1.78 km/L
Global Cycle Improvement
+27.1%
This represents a significant improvement over the typical mixed-cycle fleet average of ~1.4 km/L.
Maintenance Benefits (Zero Soot)
- DPF Protection: The hydrogen-enhanced combustion significantly reduces particulate matter, eliminating active DPF regenerations and saving fuel normally wasted on cleaning the filter.
- Extended Oil Life: Cleaner combustion reduces carbon blow-by, keeping engine oil cleaner for longer intervals.
Conclusion
The 360ES-PEM system successfully validated its ability to maintain torque and efficiency in scenarios where diesel engines typically struggle. Achieving a sustained 1.28 km/L with 65 Tons of payload is a major engineering extension, proving the technology is not just a fuel saver, but a heavy-duty torque enhancer.
