Freightliner Cascadia / Cummins X15

A success case study in heavy haul efficiency optimization, demonstrating significant fuel savings under severe service conditions.

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.

Vehicle

Unit 333 - Freightliner Cascadia (2023)

Engine

Cummins X15 (Efficiency Series)

Technology

360ES-PEM-15L

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): Double-tanker configuration with 65-Ton gross towed weight.
  • Operational Cycle: Average speed of 28 km/h creates 'Ghost Mileage', penalizing economy.
  • The Baseline: Under these conditions, the baseline drops to 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 front flame 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.

MetricIndustry Standard (Baseline)With 360ES-PEMImprovement
Fuel Economy1.10 km/L1.28 km/L+16.36% Efficiency
Consumption90.9 L/100km78.0 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%.

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.
