Effect of hydrogen supplementation 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.

Carbureted engines do not have computers and there is nothing that interferes with the operation of HHO.

These installations require only a hydrogen generator and a Current Controller.

Injector, sensor and hydrogen controllers

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.

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
 

Engine sensor controllers

To meet expectations of the ECU and accommodate the altered combustion created by hydrogen, it is important to adjust and balance the sensors of the fuelling system

Better Fuel controllers are the most complete fuel optimization systems available today. A powerful microprocessor and sophisticated programming carefully enhance your fuel injection system. The result – an excellent reduction in fuel consumption while preserving the original engine performance.

These devices control all the sensors of the fueling system. Most importantly, they balance the signals of the sensors and maintain harmony within the vehicle’s computer system; which is the key to fuel savings.

 

How engine sensor controllers work

The computer of the car ECU monitors the Oxygen sensors in order to decide how much fuel to use at any given time.

  • Oxygen sensors controller EFIE adjusts the signals coming from the oxygen sensors to make the ECU think that there is too much fuel in the engine. The ECU responds by reducing the amount of fuel sent to the system.
  • MAP sensor provides the vehicle’s ECU with information about the load on the engine. In other words, how hard the driver is pressing on the accelerator pedal. The MAP controller makes the vehicle think it is always driving down a hill, therefore requiring much less fuel.
  • IAT controller makes the ECU think that the air entering the engine is warmer than it really is. This results in beneficial adjustment in ignition timing and also a reduction of fuel consumed.

How AutoTuner Injector controller works

AutoTuner Injector Controller reduces fuel consumption by dynamically shortening and optimizing every fuel injector pulse sent to the engine.

Fuel reduction is made possible due to the fact that vehicles use an excessive amount of fuel to compensate for the most extreme operational conditions.

The presence of excess fuel is made even more apparent when HHO is installed. HHO increases the efficiency of the engine resulting in dramatically reduced fuel consumption.

AutoTuner is a fully automated device that takes control of the injection system. It maintains original engine performance while achieving excellent economy gains.

AutoTuner Injector Controller can be used with or without hydrogen.

 
 

Fuel saving results:

AutoTuner alone: 18-35%

AutoTuner + Hydrogen: 25-55%

 

PWM current controller for hydrogen HHO generators

A Constant Current PWM is used to control the current supplied to the hydrogen generator, the amount of hydrogen produced and the temperature of operation.

Hydrogen production is based on electrolysis which generates substantial heat. When the generator becomes hot, it consumes more electricity, which in turn causes the generator to continue getting hotter and conduct even more electricity. For example, if the current is set at 10 amps it can increase up to 15 amps when hot.

This undesirable condition is called “Thermal Runaway” that will inevitably boil the water in the system and stop hydrogen production.

To prevent this problem, every hydrogen installation requires a constant current controller to provide a fixed, stable supply of current to the generator.
