Engineering-complete.
Manufacturing-ready.
Built to aerospace-adjacent standards. HCU-128™ is not a mechanical add-on — it is a software intelligence layer that transforms any diesel engine. Patent CA 3,280,535 active.
Per-cylinder precision. Real-time adaptive control.
H₂ Stored at 350 bar
High-pressure composite cylinders (CSA HGV 3.1) behind cab. Reduced to ~3 bar via regulator.
Per-Cylinder Injection
H₂ metered directly to each cylinder — not the manifold — enabling precise dosing and better combustion.
HCU-128™ Adaptive Control
ARM Cortex-M7 monitors RPM, load, temp in real-time. Closed-loop mass-flow control. Torque-based blending logic.
Enhanced Combustion
Hydrogen's 9× faster flame speed promotes more complete diesel combustion — same power, less fuel.
Triple-Redundant Safety
SW shutdown + solenoid cutoff + hard-line isolation. Leak detectors. Thermal PRDs. ISO 26262 certified.
Built to last 10+ years in the harshest conditions.
Every relevant standard. In scope from Day 1.
Element 72 First-Mover: NRCan classifies H₂ dual-fuel retrofits as "Element 72 — Partial Gap" in Canada's H₂ Codes & Standards Roadmap. Hydrix enters now to help shape the standard, not just comply with it.
Three moats that compound.
Proprietary hardware + adaptive software + clear regulatory pathway. Each layer reinforces the others.
