Experimental Spray Investigation of Biodiesel Fuels Derived from Corn Oil and Canola Oil

Abstract

Spray characteristics of fuels are one of the most important factors for engine research owing to their relationship between performance output and emission level. The aim of this study was to investigate the spray behavior of biodiesel fuels derived from corn oil and canola oil, utilizing a piezo injector. Effects of ambient pressure and injection pressure on spray characteristics like spray penetration length and spray cone angle were investigated in a constant volume combustion chamber. Ambient and injection pressures were in range of 0-15 bar and 600-1000 bar, respectively. As a result of this study, sampled biodiesel fuels have longer penetration and smaller spray angles. This can be explained by having higher viscosities resulting in slower evaporation and atomization.
