Using an 8-hole Port Fuel Injector, this study describes the performance of gasoline-ethanol mix sprays at varying pressures. The perforations are positioned radially. At 1 bar, 2 bar, and 3 bar injection pressures, the spray characteristics are measured using Digital Image Processing Technique. Researched here are the spray behaviours of pure gasoline and gasoline-ethanol mixtures with 3:1 and 1:1 concentrations of Ethanol. The injector's necessary Pulse is produced using an Arduino UNO. Photos of the spray are taken using a fast shutter speed camera and then analyzed in MATLAB to determine its properties. Canon 5D Mark II is the camera model utilized. Spray angles and penetration depths improved as pressures rose. Even though there is a large gap between the viscosities of gasoline and Ethanol. The spray characters look the same at various pressures. This goes against the usual expectation that spray angles would decrease with increasing viscosity for a given surface tension.
