RESULTS OF NASA’ S EXPERIMENTS WITH HYDROGEN IN INTERNAL COMBUSTION ENGINES

The combustion of hydrogen with gasoline or diesel fuel in internal combustion engines has the potential to produce lower emissions and higher thermal efficiency for several reasons.

First, excess oxygen in the charge further oxidizes unburden hydrocarbons and carbon monoxide.

Second, excess oxygen lowers the peak combustion temperatures, which inhibits the formation of oxides of nitrogen.

Third, the lower combustion temperatures increase the mixture specific heat ratio by decreasing the net dissociation losses.

Fourth, as the specific heat ratio increases, the cycle thermal efficiency also increases, which gives the potential for better fuel economy.”

To summarize:

The more efficient HHO engine has more fuel energy converted into useful mechanical energy and less into wasted thermal energy.

This is apparent to the user in increased fuel economy, lower combustion temperatures and approximately 100 C lower exhaust temperature.

The HHO assisted combustion ignites faster and more completely. The same amount of fuel explodes more thoroughly creating more power. This power is transferred into mechanical energy and not heat.

Further, the generated force acts when it is supposed to – at the beginning of the combustion stroke of the engine. Not later when the piston is already half way down the stroke or even worse, while returning on the exhaust stroke.

Residual combustion on the exhaust stroke impeded engine rotation (lowering economy) and increases exhaust temperature and shortens the life of the exhaust valves.
