Effect of B20 heating on the macroscopic fuel spray characteristic

Abstract

Biodiesel is a fuel made from plants or animals. Biodiesel has received much attention from various researchers around the world to be developed. The impact of higher viscosity is the reduced quality of the injection spray produced. The purpose of this study was to determine the effect of heating on spray characteristics. The fuel used in this study is biodiesel 20% (B20). The method used in this study is by heating the fuel using a heater and testing the spray using an injector tester then recording it using a 240 FPS speed camera. Experimental data shows that the heating effect affects the penetration length, at 65°C spray length 49.1 cm, 6.6 cm shorter than ambient temperature. This is also in line with the average spray velocity which has decreased by about 0.6 m/s at 65°C compared to the ambient temperature. While the spray angle changes, at 65°C the spraying angle reaches 22.1°, 2.6° wider than the ambient temperature.
