Abstract
In order to improve the combustion of two B20-based Ceiba Penandra (CPNTOME B20) and Nigella Sativa (NIZSAOME B20) selected for the analysis, experimental Investigations into a modified diesel engine have been conducted with artificially induced swirl techniques implemented on both the piston and the head of the cylinder. B20 Biodiesels Used to decrease dependence on fossil-based fuels and there by address the alarmins emission levels in the atmosphere as biodiesels are renewable and are carbon neutral candidates. Growing number of piston grooves and number of cylinder head grooves and bridges increase engine output in terms of higher thermal break efficiency (BTE), lower hydrocarbons (HC), carbon monoxide (CO), smoke emissions while CPNTOME B20 showed higher performance while NOx increased from the two B20 blends.
