Effect of Hydrogen HHO on emissions

Adding HHO to an internal combustion engine, results in a faster, more complete combustion of the existing fuel.

Faster and more thorough combustion means that more energy is transferred mechanically to the engine, instead of wasted heat through the exhaust. This has a positive impact not only on power and fuel economy, but also in emissions (as exemplified in the test report by *Eurofins below).

The much faster flame propagation speed of hydrogen is responsible for this and is often compared to a giant “spark plug” in the engine that ignites all the combustible fuel.

In summary, vehicle emissions are mostly comprised of 5 gases (the 6th is applicable to diesel fueled engines):

1. HC
2. O2
3. CO
4. CO2
5. PM
6. NOx

1. HC – Hydro Carbons are essentially unburned particles of fuel that are passed through the entire engine, through the exhaust and into the atmosphere. This is the gas that accounts for smog in our cities. Hydrocarbons are typically reduced by 30-40%.

2. O2 – Oxygen is NON-POLUTING and necessary for our existence. Note the significant increase of clean oxygen as measured by 5-gas analyzers.

3. CO – Carbon Monoxide. This clear, odorless yet deadly gas gets reduced in the range of 25-50%.

4. CO2 – Carbon Dioxide, responsible for the “green house” effect on our planet is typically decreased by 40-60%

5. PM – Particulate Matter is the “solid particles and liquid droplets” in the exhaust of diesel engines, more commonly referred to as “soot”. As HHO is directly responsible for a more complete combustion, this emission is drastically reduced. 70-80% reductions are commonplace, with frequent reports of 90%+.

6. NOx – Nitrogen monoxide and additional oxides are responsible for the “acid rain” pollution that is apparent in metro areas such as Los Angeles.
