Our HHO generators use electrolysis to split water (Hâ‚‚O) into hydrogen (Hâ‚‚) and oxygen (Oâ‚‚), forming HHO gas. This gas is then directed into the combustion chamber, via the air intake manifold, where it mixes with our normal fuel.

We use a small amount of the car's energy to produce hydrogen, but when added to the combustion, it enhances efficiency, releasing more energy than is used to produce the hydrogen itself, significantly reducing fuel consumption and pollution!

NASA conducted several studies on using hydrogen as a supplemental fuel in an internal combustion engine running on gasoline. Their research specifically demonstrated that the higher flame speed of hydrogen allowed for an extended efficient lean operating range in a gasoline engine. Lean-mixture-ratio combustion in internal combustion engines has the potential to produce low emissions and higher thermal efficiency for several reasons:

1. Excess oxygen in the charge further oxidizes unburned hydrocarbons and carbon monoxide.
2. Excess oxygen lowers peak combustion temperatures, inhibiting the formation of nitrogen oxides.
3. Lower combustion temperatures increase the mixture's specific heat ratio by reducing net dissociation losses.
4. As the specific heat ratio increases, the cycle's thermal efficiency also improves, potentially leading to better fuel economy.

CALTECH, also conducted research on calculating the thermal efficiency of system fuel economy using supplemental hydrogen. The overall engine efficiency increases and outweighs the energy loss incurred in generating hydrogen, resulting in improved fuel economy for the system as a whole.

Engine Torque

An average increase of 19.1% in engine torque is obtained using HHO compared to pure diesel operation. The power gain is due to the oxygen concentration in HHO gas and the improved mixing of HHO with air and fuel, which enhances combustion. 

The results show that the addition of HHO can significantly enlarge the flammable region and extend the flammability limit to lower equivalence ratios. Since HHO gas has a low ignition energy and a fast flame speed, the HHO-diesel mixture ignites more easily and combusts more quickly than pure diesel fuel. Thus, improved torque at high speeds can be achieved.

Engine Temperature

The high laminar flame velocity of HHO reduces ignition delay and shortens the combustion period, leading to lower heat losses and a combustion process closer to ideal constant-volume conditions. This results in an increased compression ratio and higher thermal efficiency, ultimately lowering engine temperature.

Engine Noise

The high burning velocity of hydroxy results in a faster increase in pressure and temperature, which may minimize knocking, especially at idle conditions (low or no load). Additionally, the reduction in the ignition delay period leads to decreased engine noise.

Fuel Consumption

An average gain of more than 20% in SFC (Specific Fuel Consumption) is achieved using the HHO system. The reduction in fuel consumption is due to the uniform mixing of HHO with air (high diffusivity of HHO) and the higher presence of oxygen, which assists diesel combustion and improves efficiency. The highest savings occur at high speeds because diesel fuel is difficult to burn completely under lean conditions due to the increased residual gas fraction and poor mixing. Since HHO has a high flame speed and wide flammability range, the addition of hydrogen helps the fuel burn faster and more completely.

Carbon Emissions

An average reduction of 13.5% in CO emissions is achieved at mid and high engine speeds. The absence of carbon in HHO gas is a major factor in CO reduction. The wide flammability range and high flame speed of HHO gas allow the engine to operate at lower loads. The HHO-diesel fuel mixture burns faster and more completely than pure diesel fuel. Thus, CO emissions at high speeds and under lean conditions are effectively reduced after HHO addition. Since HHO gas contains oxygen, higher combustion efficiency is achieved, resulting in lower CO emissions.
