2013 Vol. 20, No. 2 299--305
EN Over the next few decades the automotive industry will be faced with a number of challenging decisions as the world’s supply of oil reduces and the global population increases beyond 7 billion. These factors have driven some researchers to look at blending fossil fuels with alternatives such as crop[...]
Journal of KONES
EN This paper presents and discusses selected research results of the diesel engine fuelled with blends of: diesel oil (DO), synthetic ethanol (ET) as oxygenated additive and small quantity of fatty acid methyl esters (FAME) used as emulsifier. Content of ethanol in diesel oil was changed in wide range[...]
