Science

Yesterday’s science arrives today. Hydrogen production developed from 19th century science. Yet this decade marks the time when technology has caught up with the science in this area. The technology now allows manufacturers to put products on the market that everyone may benefit from.

Here you may find a list of more recent science articles on the subject. Key scientists and engineers have documented these advances. They have allowed us greater understanding of the science of hydrogen. The science of hydrogen is becoming a standard feature of engine application. And we are witnesses of these facts of science history.

 

The following are examples of abbreviations used in some of the below-mentioned publications:
ICE – Internal Combustion Engine, and SI – Spark Ignition; as in an “SI engine”.

Emissions and Total Energy Consumption of a Multi-Cylinder Piston Engine Running on Gasoline and a Hydrogen-Gasoline Mixture

Technical Note Report # E-9105, May, 1977,
National Aeronautics and Space Administration, Washington, D.C.

Adding hydrogen to gasoline significantly increased flame speed and allows for a leaner air/fuel ratio. All emissions levels decreased at these leaner conditions.
