Liquid fossil fuels are the main source of energy in transportation vehicles and aviation for many decades. This dependence on fossil fuels can be reduced by liquid biofuels blended with fossil fuels or utilized purely. The purpose of this research is to authenticate a method for different fuels for measurement of injection rate based on the spray momentum measurement and total fuel mass injected. So, in this research B50, B100 and simple diesel fuel hydraulic behavior was investigated. All the measurements have been taken in a chamber/cylinder filled with nitrogen gas at high pressure, which results in the gas density of 22.7kg/m(3) and 34.6kg/m(3), using the injection pressures 600, 800 and 1000 bar. Spray angle and spray tip penetration measurements presented that an increment in injection pressure boosted fuel spray dispersion whereas increment in ambient pressure showed a reverse effect. All fuels have almost same momentum flux for their regarding conditions. B50 and B100 have a greater momentum efficiency than simple Diesel. Momentum flux increases to a factor of almost 1.4 with every 200 bar rise in injection pressure. The fuel mass injected showed a reduction in fuel mass for B50 2-3% and for B100 5-6% as compared to diesel fuel. (C) 2021 THE AUTHORS.
