Abstract

This study experimentally investigates the effects of using biodiesel made from Ruta oil in 
combination with diesel fuel, on diesel engine performance. The blending ratio of the prepared Ruta 
methyl ester (RME) biodiesel with nominal diesel fuel might range from 10% to 30% by volume. The 
experimental study focuses on diesel engines operating at a steady speed and exposed to varying loads. 
The results show that adding RME biodiesel slightly lowers the BTE and enhances the BSFC and BSEC. 
Using data gathered from tests. Experimental results showed that a 20% RME biodiesel blend produced 
the best results, with HC and CO emissions dropping dramatically as the blend percentage increased. 
The results show that adding nanoparticles somewhat increased the BTE while decreasing the BSFC. 
The results acquired are confirmed by comparing them to those reported by other researchers operating 
under the same conditions.
