Recommended equipment

The correct combination of a hydrogen generator and an electronic controller is required to achieve maximum fuel saving results.

  • Select generator from the chart below
  • Use an AutoTuner controller for a gasoline engine
  • Use a DieselTuner controller for a diesel engine

Gasoline engines consume excessive fuel, while diesel vehicles operate on an excess of air. These entirely different technologies require different approaches.

Better Fuel has developed unique solutions to effectively reduce fuel consumption on both types of engines.


Hydrogen generator selection

The choice of a generator is determined by the engine size of the vehicle you plan to install this equipment on.

Effect of hydrogen in different types of engines

Fuel injected vehicles are equipped with multiple sensors. The ECU monitors all the sensors and it is programmed to expect a certain “normal” behavior.

Hydrogen alters the combustion properties of the existing fuel. When the sensors detect this unexpected condition, the ECU responds by adding more fuel and negating the improvement in fuel economy.

If sensors are not adjusted properly, there will be more power and torque, but no fuel savings.

Injector, sensor and hydrogen controllers

AutoTuner is a fully automated fuel reduction system for all gasoline engines. It consists of three independent products integrated into one universal device:

  • Injector Controller
  • Fuelling system Sensor Controller
  • High output Current Controller for a hydrogen generator

DieselTuner is specifically designed for diesel engines. It consists of two products:

  • Fuelling system Sensor Controller
  • High output Current Controller for a hydrogen generator

Typical results:

AutoTuner alone: 18-35%

AutoTuner + Hydrogen: 25-55%

DieselTuner + Hydrogen: 15-40%
