Eco-neev , a nano-diesel fuel additive is a scientifically and commercially proven diesel fuel combustion catalyst which reduces fuel consumption,greenhouse gas emissions(CO₂) and other harmful exhaust emissions. Eco-neev has gone through several trials in the transport and mining sectors in the last 5-6 years in countries like U.K. (the largest bus company in U.K.), Europe (Transport), Russia (Mining) and USA (Mining). In domestic market, Nanotech Solutions has recently carried out a trial with Himachal Road Transport Corporation (HRTC) and TATA Steel which produced excellent results.

Eco-neev:

• SAVES FUEL
• CLEANS ENGINE
• LOWERS HARMFUL EMISSIONS

"The less you burn, the more you earn"

The reduction in CO₂ emission is a critical issue in mitigating the effects of global warming; however, the damaging effects of soot on both climate change and human health are less well known. Twelve million tonnes of soot are released into the atmosphere per year, of which, in urban evnironments, up to 45% is from diesel-powered road vehicles (Highwood and Kinnersley 2006). Some authors consider that soot is the second most effective atmospheric global warming pollutant and that a reduction in soot emissions might be a relatively easy 'win'in the battle against global warming (Bond and Sun 2005).

Clearly, new products that reduce both CO₂ production by reducing fossil fuel consumption, and soot production by promoting enhanced combustion have a potentially huge benefits to the consumer in reduction of fuel bills and in the reduction of harmful exhause emissions.

Development of Cerium Oxide:

The development of an engine exhaust system designed to reduce the emission of unburnt hydrocarbons, carbon mon oxide (CO), and nitrogen oxides (NOx) began in the 1970s and led the development of the CeO₂-based three-way catalyst system or catalytic converter present virtually all vehicles in the Western world today (Gross et al.).

Benefits of Cerium Oxide

Some rare earth oxides have the ability to donate and store oxygen from their crystal lattices depending on a variety of environmental factors, particulary the atmosphere surrounding the CeO₂. In practice, in an oxygen-lean environment CeO₂ will act as a catalyst, donating oxygen and assisting in the combustion of various species, such as hydrocarbons and soot. Thus, the intoduction of CeO₂ into engine exhausts reduces the pollutants emitted from the engine during combustion.

Concept of Eco-neev

The Eco-neev concept is to allow the catalytic benefits of CeO₂ to be available to the fuel during the initial combustion, within the cylinder itself. There is also an increase in the catalytic activity of CeO₂ as particle size decreases, rendering a nanoparticle form of the material attractive from a fundamental property point of view (Logothetidis et al, 2003). As a fuel additive the use of ceramic such as CeO₂ is novel, as the overwhelming majority of current fuel additives are based on organic molecules and polymers (Bosch Automative Handbook, 5th edition 2000). There is a number of technical challenges to incorporating such materials into fuels, however, the most notable of which is the density of the material, rendering an exremely small particle size a required parameter for suspension in the fuel (there must be no settling of the material over time).
