Diesel fuel is the most energy dense transportation fuel available, and the diesel engine is the most efficient means to transfer this energy density into useful work.


At Speed of Air, we believe that the use of fossil fuel will be a necessary engine of economy for many decades to come. However, we also know that innovative solutions are available now that can have an enormous impact on reducing particulate matter (PM), Oxides of Nitrogen (NOx), oxides of Sulphur (SOx) and hydrocarbons.


Without the use of expensive alternative fuels or after-gas treatments, Speed of Air's Clean Engine Technology promises a clear advantage to your bottom line today while ensuring a cleaner environment for tomorrow.
