Analysis of performance and emission parameters of IC engine fuelled with neem biodiesel and n-octanol additives

Abstract

The usage of biodiesel as a source in diesel engines is prevalent in recent years in the aim of reducing emission that are produced when using diesel. Researches are undergoing in the fields of alternative fuels to improve the energy content and combustibility of biofuels used in engines. Biodiesel being a renewable energy source is widely used as an alternative for fossil fuel. In this test octanol (Oct) is added to neem biodiesel (NBD) and diesel (D) as an additive to create the fuel blends and its impact upon performance and emission characteristics are evaluated. The fuel properties are found be improved on using higher alcohol additives such as octanol which is having high energy content as well as high cetane number and are also easily miscible in biodiesel and diesel. From the experiment conducted on diesel engine using both diesel as well as with prepared blends, significant decrease for all emission associated with neem biodiesel, diesel and octanol blends was found without any substantial loss of performance compared with results while using neat diesel. The results indicate that blending octanol with biodiesel blends is a viable option as alternative fuel source for CI engines.
