Impact of Nanoparticle Based Diesel Fuel Additive on Air Pollutants: Engine Emissions
Fuel additives have played a major role in improving fuel performance for many decades. Additives are chemical compounds added in very small quantities to diesel base fuel to modify or create certain fuel properties. Fuel additives improve fuel efficiency, reduce diesel soot emissions, and alter the emissions of carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbon (HC) species, including several hazardous air pollutants (HAPs).
Cerium Oxide nanoparticles as fuel additives have been increasingly used in diesel engines to promote combustion by decreasing the amount of Soot in diesel exhaust and increasing the fuel efficiency. However, few studies have evaluated the impact of these nanotechnology based fuel additives on pollutant emissions.
To assess the impact of cerium oxide nanoparticles on the environment, scientists at HARC are studying how these nanoparticles affect diesel engine exhaust emissions. This work is led by Dr. Asanga Wijesinghe, Research Associate at HARC Engine & Emission Control Program.
