Abstract

Fuel spray injection plays a main role in determining the performance of dieselengines, where the spray pattern illustrates fuel combustion occurs in thecombustion chamber. Characteristics of Sauter Mean Diameter (SMD) spray isdevoted to fuel evaporation, and mixing and combustion quality affected bypressure injection (P) and the physical chemical properties of the fuel (density,surface tension, viscosity and boiling point). From fuel spray test results showedthat fuel evaporation characteristics of fuel at a certain pressure effect on engineperformance. The higher the injection pressure will reduce the diameter of thefuel sprays after injection (SMD), thus speeding up evaporation and mixingprocesses between fuel and air in the combustion chamber with resulted thecombustion process is more completelyKata kunci: characteristics of fuel spray, diesel fuel, DME.

Abstract

Fuel atomization plays a main role in determining the performance of dieselengines, where the spray pattern illustrates fuel combustion occurs in thecombustion chamber. From fuel spray test results showed that fuel evaporationcharacteristics of fuel at a certain pressure will effect on engine performance.The higher the injection pressure will reduce the diameter of the fuel sprays(sauter mean diameter), thus speeding up evaporation and mixing processesbetween fuel and air in the combustion chamber with resulted the combustionprocess is more completely. Analysis of fuel atomization simulations performedat injection pressure 150, 180 and 235 bar on the distribution of size,temperature and concentration of air+fuel mixture. Physical chemical parametersresulting are the size and temperature distribution patterns fuel+air mixturesprays. DME is feasible to be used as alternative fuel in diesel engines by adding2–5% lubricant additives. The use of diesel+DME 50/50 mixed fuel provides thelowest fuel consumption by generating power of 3x2,975 watts.Kata kunci: kinerja mesin, solar, DME, simulasi atomisasi, dinamika fluida
