Abstract: Due to global warming and pollution, emission norms are very firm all over the world, in order to reduce these emissions the current research is going on in alternative fuel. The study of fuel spray characteristics is important, which influences the emission, combustion and mixture formation in the engine. The spray characteristics of fuel mainly depend on fuel injection pressure, fuel density, viscosity, temperature, combustion chamber pressure and injection duration. The main aim of the work is to study the macroscopic spray parameters in a glass chamber for Chicha oil methyl ester (CCOME) and diesel fuel and non dimensional analysis of spray characteristics of tested fuel were obtain from the images captured by a high speed video camera. It was found that CCOME has longest spray tip penetration and spray area when compared with diesel fuel. It was found that tested fuels exhibit better spray characteristics at higher injection pressures.

Keywords: macroscopic spray parameters; spray shape factor; CCOME; Chicha oil methyl ester; diesel; dimensionless analysis.
