Experimental investigations on diethyl ether as fuel additive in biodiesel engine
Ramadhas, A.S.; Jayaraj, S.; Muraleedharan, C. - In: International Journal of Global Energy Issues 29 (2008) 3, pp. 329-336
In this work, biodiesel (methyl esters) is produced from unrefined rubber seed oil by two-step transesterification process. Biodiesel engines are prone to cold-starting problems in winter seasons and emit more nitrogen oxides. To overcome these problems, diethyl ether is used as a fuel additive...
