Variation of Fuel Characteristics of Diesel with the Use of Biodiesel and Alcohols (ethanol, methanol, 2-propanol, 2-butanol)

Nowadays, many researches are focused on alternative fuels in internal combustion engines because fossil-based fuels have many negation not only environmental aspects but also economical aspects. Especially, Diesel engines need alternative fuels because of their widespread use and harmful emissions mainly Nitrogen Oxides and Particulate Matter. Alcohols and biodiesel are the main alternative fuels to diesel fuel. They can be used in diesel engines as additive without any modification of engine. In this study, the effect of blending alcohols (ethanol, methanol, 2-propanol, 2-butanol) and biodiesel with diesel fuel on the diesel fuel properties was investigated experimentally. The alcohols were blended as 15% and biodiesel as 20%, 40% and 60% with diesel fuel. The results showed that the use of alcohols with diesel fuel as alternative fuels leads to a decrease in density, viscosity, calorific value, flash point and cetane number values. On the other hand, biodiesel led to an increase in density, viscosity and flash point values, and a decrease in Calorific value and Cetane Number.
