By optimizing spray characteristics we can minimize raw emissions from the diesel engine which are mainly NOx and PM.As engine manufacturers are under increasing regulatory pressure to reduce NOx and particulate emissions by emission governing agencies, there is need to study effect of spray characteristics. Spray characteristics such as spray angle, spray pattern, atomization, fuel droplet size and distribution, spray tip penetration and nozzle type and nozzle geometry have significant effects on Diesel engine performance parameters and emissions. Turbulent characteristics of air fuel mixing are affected by the shape and condition of the nozzle inlet that is nozzle geometry. In this paper the effects of nozzle whole geometriesare discussed in brief.
