How the Hydrogen Generator Works

Our PEM Hydrogen Generator Kit introduces a small, precisely controlled amount of hydrogen and oxygen gas (HHO) directly into your engine's air intake system. This revolutionary process ensures a more complete and efficient combustion of your vehicle's conventional fuel—be it diesel or gasoline—delivering substantial business advantages

01

On-Demand Hydrogen Generation (PEM Technology)

Our system uses the highly efficient PEM (Proton Exchange Membrane) water electrolysis technology. This process electrolyzes pure water to instantly generate clean hydrogen and oxygen without the need for corrosive chemicals or additives. The system operates with low power consumption (4V 15A), in contrast to conventional hydrogen generators.

02

Optimized Combustion

Hydrogen is an ideal combustion gas because its diffusivity is 12 times and its flame propagation speed is 8 times that of fuel. When a proper amount of hydrogen is introduced, it significantly improves the combustion efficiency of your fuel, especially during frequent starts, acceleration, and at low engine speeds (under 3000 RPM), where fuel consumption is typically maximized and combustion is insufficient.

Intelligent Microcomputer Control

The core of our system is our independently developed Microcomputer, which features a high-precision, low-energy consumption 7 nanometer chip. It continuously reads real-time engine data and utilizes a high-precision background algorithm to dynamically adjust the engine's injection time, ignition timing, and transmission shift time based on driving habits and the amount of hydrogen gas. This ensures the trace hydrogen ignites at the most accurate time, maximizing the engine's thermal efficiency and fuel combustion efficiency.


How Hydrogen Conversion Works


Input: Pure water

Inside the onboard reservoir, distilled water is supplied to a sealed electrolysis cell.

The PEM electrolysis process splits the water (H₂O) into its pure components — hydrogen (H₂) and oxygen (O₂) — using controlled electrical current.

Unlike older “HHO” or additive-based systems, PEM cells require no chemicals or electrolytes, making them clean, safe, and virtually maintenance-free.

Technical Detail:

  • Operates at low voltage (12–24 V DC)

  • Produces high-purity hydrogen gas on demand

  • No storage — hydrogen is created only when the engine is running

The generated hydrogen is fed through a precision control unit and introduced into the air intake manifold of the engine.

The small volume of hydrogen mixes with the incoming air–fuel mixture, acting as a combustion enhancer rather than a replacement for your fuel.

What Happens:

  • Hydrogen raises the flame propagation speed

  • Fuel droplets burn more completely

  • Less unburned carbon exits the exhaust

This process improves thermal efficiency and reduces fuel waste, resulting in noticeable gains in performance and mileage.

Engine Benefits:

✅ Smoother throttle response

✅ Reduced engine knocking

✅ Cleaner spark plugs and valves

During combustion, the enhanced air–fuel mix produces a hotter, more uniform flame, converting more of the fuel’s chemical energy into motion and less into waste heat or soot.

As a result:

  • Fuel savings: Up to 20–25 % in typical road use

  • Lower emissions: Noticeable reduction in CO₂, NOx, and DPM (Diesel Particulate Matter)

  • Cleaner engine internals: Hydrogen helps remove existing carbon buildup

  • Extended maintenance intervals: Cleaner combustion means fewer oil and filter changes

Environmental Impact:

Hydrogen-assisted combustion directly reduces soot and particulate emissions, helping vehicles meet stricter Australian and Euro emission standards without costly engine overhauls.

Every Hydro Auto Tech system includes an electronic controller that synchronises hydrogen production with engine activity:

  • Starts producing hydrogen only when the engine is on

  • Automatically adjusts output based on RPM or throttle load

  • Monitors temperature, water level, and electrical current

  • Engages safety cut-offs for overheating or dry-cell conditions

This ensures consistent, safe operation while maximising performance.

Because the hydrogen is generated directly from water and electricity already available from the alternator, the process adds only a minimal load on the electrical system.

Over time, the system pays for itself through reduced fuel consumption, lower emissions, and extended engine lifespan.

Our kits suit all vehicles makes and model as long as the on board computer allows for additional components.

No, our hydrogen generator kits are not pressurized units therefore this modification does not require compliance plates.

We all drive our vehicles differently and in some cases of city driving you might get slightly less fuel saving to highway driving, but overall, you will see improved fuel efficiency.
