Abstract

Fuel atomization plays a main role in determining the performance of diesel
engines, where the spray pattern illustrates fuel combustion occurs in the
combustion chamber. From fuel spray test results showed that fuel evaporation
characteristics 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 processes
between fuel and air in the combustion chamber with resulted the combustion
process is more completely. Analysis of fuel atomization simulations performed
at injection pressure 150, 180 and 235 bar on the distribution of size,
temperature and concentration of air+fuel mixture. Physical chemical parameters
resulting are the size and temperature distribution patterns fuel+air mixture
sprays. DME is feasible to be used as alternative fuel in diesel engines by adding
2–5% lubricant additives. The use of diesel+DME 50/50 mixed fuel provides the
lowest fuel consumption by generating power of 3x2,975 watts.
