Influence of Renewable Fuels and Nanoparticles Additives on Engine Performance and Soot Nanoparticles Characteristics

The fuel combustion in diesel engines can be improved by adding nanomaterials to the which result an reduction pollutant emissions and enhance quality of combustion. engine performance soot nanoparticles characteristics were evaluated this study with copper oxide (CuO2) rapeseed methyl ester (RME) under variable speeds. addition CuO2 RME significantly improve brake thermal efficiency (BTE) decline specific consumption (BSFC) 23.6% 7.6%, respectively, compared neat fuel. inclusion into led decrease concentration number particulate matter (PM)by 33% 17% comparison without nano additives, respectively. Moreover, PM is decreased 31.5% during various It was also obtained that emitted particles (npo) reduced 23.5% diesel, while diameter (dpo) increased 8.6% diesel. Furthermore, size more than
