Karakteristik spray diesel dan campuran biodiesel nyamplung pada ruang chamber dengan variasi temperatur ambient

Spray characteristics have an important role in improving the quality of combustion compression engines. This study analyzes effect ambient temperature on spray including tip penetration, angle and velocity spray. The research method uses experimental with variations 60 o C, 80 100 C controlled using a thermocouple pressure 0.3 MPa. composition fuel diesel (diesel 100%), B30 (30% biodiesel), B100 (100% biodiesel). Image recording camera speed 480 fms. Based results, increases at all temperatures has is lower.
