Experimental and empirical investigation of a CI engine fuelled with blends of diesel and roselle biodiesel

Abstract The continuous rise in demand, combined with the depletion of the world's fossil fuel reserves, has forced the search for alternative fuels. The biodiesel produced from Roselle is one such indigenous biodiesel with tremendous promise, and its technical ability to operate with compressi...
