Environment effect of La2O3 nano-additives on microalgae-biodiesel fueled CRDI engine with conventional diesel

In this present work, corn oil biodiesel with La2O3 was used as an additive with neat diesel fuel and blends were prepared. La2O3 nanoparticles are dispersed in the emulsions with different dosage levels of 50, 75, and 100 ppm. A single-cylinder, four-stroke CRDI diesel engine is made to run on different fuel concentrations to study the effect of emission characteristics of the fuel. The test engine was operated under constant engine speed (1500 rpm) and different engine load test conditions. According to the experimental results, fuel blends with biodiesel fuel emission increases CO2 and NOx and reduces the CO, HC, and smoke emissions compared with the B20 fuel.
