Particulates and gaseous emissions from an engine running on fossil fuel (diesel/gasoline) have severe health and environmental impacts. Even after the improvement in engine technology and use of after-treatment of emissions technology, the exhaust pollutants are not regulated appropriately. Latest legislations are getting more stringent and geared towards measuring particulate number concentration in addition to traditional mass-based measurements. Hence, upgrading the quality of fuel to reduce emissions and accurate measurements of these emissions become necessary. Due to their large specific surface area, nano-additives help to improve the combustion, performance, and emission characteristics of the fuel. The research page outlines the setting up of the baseline characteristics of the engines.
