dc.description.abstract | The use of biodiesel fuel has a very high viscosity and density
compared to diesel oil, this makes diesel engine performance
less than optimal. With the addition of gasoline to biodiesel, it
will reduce the viscosity and density of biodiesel and have a
lower flash point. And also the fuel heating process aims to
reduce the level of viscosity and density of the fuel so that it is
the same as diesel oil. This study aims to know the spray
characteristics of fuel B0 (100% diesel oil), B30 (30%
biodiesel and 70% diesel oil) and B30G5 (95%B30 and 5%
diesel oil) with temperature variations 60ºC, 80ºC, and 100ºC
on injection pressure of 17 MPa. The results of the tests that
have been carried out that the increase in temperature of the
fuel and variations in injection pressure will affect the value of
the spray tip penetration, and the spray area. The result of the
spray characteristic test that produces a good value is B0 fuel
(100% diesel) but the closest to the B0 fuel value is B30G5. | en_US |
