The Performance of a Diesel Engine Blended With Coffee Bean Residue Pyrolysis Oil
In recent years,global economic development has led to rises in crude oil prices and the greenhouse effect.Developing renewable energy has become a major issue internationally,Biomass energy is one form of renewable energy.Biomass enery as a transportation fuel can be deliverd from fats,starch biomass fuel or biofuel,and cellulose biofuels.Because concerns exist that fats could lead to a food crisis,most nations have focused on researching and developing cellulose.In this study,we used coffee bean residue as a fuel source.We employed the pyrolysis process to produce pyrloysis oil products.We also used appropriate emulsion technology and suitable amounts of petroleum diesel for adding coffee bean residue to investigate the influence that coffee bean residue pyrolysis oil with low-add ratios (5 vol.%) has on diesel engine performance.The results indicated that coffee bean residue pyrlosis oil with low-add ratios resulted in an earlier diesel engine ignition time.Additionally,at low rpms,the diesel engines indicated specific fuel consumption (ISFC) was relatively low.However,ISFC was superior at higher rpms.In summary,when adding a portion of coffee bean residue pyrlosis oil to diesel engines,performance was superior during high-rpm operations compared to lower rpm.Pollutant emissions were also significantly improved.The results of this study can provide a reference for future high-add ratios and high-load engine tests.
