Description
Summary:Biodiesel is well known as an alternative to the CI engines owing to being renewable, environmentally friendly, biodegradable, and non-toxic with fewer emissions. Biodiesel is prepared from several types of vegetable oils, and the current study uses Sterculia foetida oil (non-edible oil). The major problem with using biodiesel blends in CI engines is emissions that rely on physicochemical properties. Hence, the current study is to evaluate the physicochemical properties of biodiesel-diesel blends with the addition of graphene nanoplatelets at different dosage levels of 25, 50, and 75 ppm. The prepared samples are expressed as SFOME20, SFOME20GNPs25, SFOME20GNPs50, and SFOME20GNPs75. The physicochemical properties are measured for prepared samples according to the ASTM standards. The inclusion of nanoplatelets improves the fuel blend properties such as density, viscosity, cetane index, flash point, fire point, cloud, and pour point. In contrast, the calorific value is a little decreased.
