Renewable fuels form an essential means to reduce greenhouse gas (GHG) emissions emitted by vehicles and non-road machines. Due to the limited production so far, different blends of renewable fuels in fossil fuels are a realistic way to implement the

ASME 2009 Internal Combustion Engine Division Fall Technical Conference.
The demand for increased use of biofuels in both on- and off-road diesel engines is growing. The carbon dioxide emissions must be reduced, but the increase in the petroleum prices and possible shortage of crude oil also promote the interest in biofue

The aims of this research are to find, in decentralized production, more economical and effective techniques based on sustainable energy to extract and transesterificate oil to fuel (the use of ethanol, catalysts, and so on), to find new more effecti
