Comparing the density of the oils: Plant (Lio, Sunflower, Neem, Nigel) and diesel

The density is an important feature, especially for biofuels, as it determines the design and technological features of feeders (pumps, injectors); more on a system installed, use of widely different density of biofuels would result in combustion setting changes with implications for maximum power, efficiency and emissions of pollutant. In our study, we report measurements of the density of vegetable oils (Lio, Sunflower, Neem, Nigel) and diesel fuel depending on the temperature. These measurements were made between 10°C and 85°C. These measurements show that the neem oil decreases very remarkable as compared to other oils as the temperature increases.
