Emission analysis on the influence of magnetite nanofluid on methyl ester in diesel engine

Özet

Increase in NOx emission is one of the most important drawbacks for using biodiesel as a potentialalternative fuel for petroleum diesel. Many studies have been carried out to reduce the NOx emissionlevel in biodiesel. The present work is the result of an attempt wherein ferrofluid is added with rice branoil methyl ester in the way of analyzing its effects on emission features. Magnetite concentrate isexothermic and is known for its characteristics of releasing copious heat at higher temperatures.Nanofluid using magnetite is synthesized by reacting Iron II (FeCl2) and Iron III (FeCl3) in an aqueousammonia solution to form Magnetite Fe3O4 (Ferro fluid). Release of heat by magnetite during thecombustion process counterbalance the conventional limitations related with biodiesel such as increaseddelay period, inferior combustion rate and higher NOx emissions etc. Experiments have been conductedwith Rice Bran Oil Methyl Ester (RBOME) and Rice Bran Oil Methyl Ester with addition of Ferrofluid(RBOMEF) and are compared with petroleum diesel. Rice Bran Oil Methyl Ester with addition of Ferrofluidhas been prepared comprising 98.7% biodiesel (Rice bran oil methyl ester), 1% magnetite basedferrofluid and 0.3% surfactant by volume is used in a CI engine. The experimental analysis reveals adecrease in HC, CO and NOx emissions of 19 ppm, 0.011% volume and 93 ppm respectively.
