Impact of Carbon Nanotubes as Additives with Cotton Seed Biodiesel Blended with Diesel in Ci Engine - An Experimental Analysis
2020
G. Ninawe and M. Tariq
In the present global scenario, fossil fuels are facing challenges due to escalating costs, increasing demand and impact on environmental pollution. In internal combustion engines, the emission characteristics and economy of the fuel are controlled by the chemical and physical properties of the fuel. Various additives are being used to act like catalysts with the fuels to improve quality of fuel, to obtain better combustion and to reduce exhaust emissions. At the time of combustion process, fuel instability reactions get accelerated by the catalysts which improve the performance of the engine. In this study, the B10, B15 and B20 fuel blends of cotton seed oil and diesel were mixed with the carbon nanotubes (CNTs) as an additive to analyse the performance and exhaust emissions of a CI engine. The carbon nanotubes were mixed with each fuel blend with the concentration of 50 ppm. All the tests were carried out for different engine loads. Tested characteristics were power, brake thermal efficiency (BTE), specific fuel consumption (SFC), and analysis of exhaust gases like hydrocarbons (HC), CO2, CO, and smoke. The experimental results showed that there was significant reduction of SFC and improved combustion by addition of CNTs. It was also observed that the exhaust emissions, CO, HC, and smoke percentage got decreased by the influence of CNTs.
