Cyclic Variations of Combustion Characteristics in Diesel Engine Operating With B20 Blends with Alcohol Additives

Biodiesel is a renewable biological fuel which has higher density and viscosity as compared to mineral diesel. However, the simple approach to reduce the viscosity of biodiesel is to blend the mineral diesel with biodiesel. While the use of alcohol additives (ethanol and methanol) in the biodiesel b...
