Fuel properties and emission characteristics of biodiesel produced from unused algae grown in India

Abstract The high price of different biodiesels and the need for many of their raw ingredients as food materials are the main constraints to be overcome when seeking the best potential alternative fuels to petro-diesel. Apart from that, some properties like high density, viscosity and acid value alo...
