Investigation on effects of cobalt-chromite nanoparticle blends in compression-ignition engine

Abstract This work provides a high-level overview of the performance parameters nanoparticle-fuelled engine emulsion. The nanoparticle cobalt chromite was created by straightforward laboratory procedure. nanoparticles were introduced at concentrations 20 ppm, 40 60 and 80 with optimal concentration being found to be Kapok methylester-20 (KME20) blend. Varying timings operated constant speed 1800 rpm. Injections can given 19, 23, or 27 degrees before top dead centre, which are referred as retardation, standard, advanced, respectively. Brake thermal efficiency is increased 7.2% when blend KME20 ppm advanced compared triggered ignition delay. Unburnt hydrocarbon carbon monoxide levels in ppm-Advanced mix reduced 37.86% 41.66%, respectively, standard injection period. Oxides nitrogen 20ppm - retardation rose 16.45 9.5 percent, duration normal injections. Increased brake for 7.5% related same without doping nanoparticles. Using kapok methyl ester doped improve performance.
